  • Handheld augmented reality system for resistive electric circuits
           understanding for undergraduate students
    • Authors: Fernando Reyes-Aviles; Carlos Aviles-Cruz
      Abstract: Augmented Reality (AR) is a recognized technology having a great potential to enhance the cognitive learning process. In this paper, a mobile AR system is proposed which helps in the understanding of resistive electric circuits for undergraduate engineering students. The designed system employs a smartphone, a measuring instrument, and a resistive circuit on a breadboard. The smartphone captures a photograph of the electric circuit and receives data from the measuring instrument (current and voltage) to calculate theoretical values and generate a layer of virtual objects which is then merged with the original image and displayed on the screen of the smartphone. In order to display the AR, a markless method is developed for a typical circuit for identifying resistors in a circuit and set virtual objects over it. The developed circuit displays (via AR) the theoretical current, voltage, power, and their measured values, as well as the error for each parameter. Technical efficiency of the developed system is 98%. Additionally, a satisfaction qualitative study is presented.

  • A computer-based educational tool for simulating multifactorial
           experiments of physical processes
    • Authors: Antonio Concha; Ana Cristina Delgado Chavez, Nagamani Balagurusamy, Rajeswari Narayanasamy, Suresh K. Gadi
      Abstract: In this article, challenges in designing example problems of multifactorial experiments for an academic purpose are identified, and an algorithm for simulating multifactorial experiments is presented. It is based on a proposed mathematical function, which mimics a physical system, can be employed for any number of finite factors, and contains a unique peak, with which a unique optimal solution for an experiment is guaranteed. The proposed algorithm is implemented on an application developed with JavaScript, HTML, and CSS, which has been tested in the classroom for highlighting all characteristics of experimental design.

  • Lecture capture use in engineering education: Influence of students’
           social and behavioral factors and teachers’ perceptions
    • Authors: Anisur Rahman; Mohammad Aminur Rahman Shah, Sanaul Huq Chowdhury
      Abstract: This paper discusses the influence of students’ social and behavioral features on lecture capture use in the learning of engineering courses, as well as teachers’ perceptions of pedagogical changes and students’ performance. Results show that the students’ perceptions about lecture capture are highly positive in terms of improving learning and academic performance. With respect to behavioral factors like attention deficit, the study suggests that a significant number of students having difficulties in maintaining attention during lectures and rely on lecture capture for further understanding. With respect to social factors, variation in the use of lecture capture has also been observed between native and non-native English speaking students, and in students with different levels of past experience in using lecture capture. Lecturers of these engineering courses have expressed optimism about using lecture capture, and have raised concerns about restrictive teaching styles, and the requirement for technological improvements and adequate training.

  • Interdisciplinary flipped learning for engineering classrooms in higher
           education: Students’ motivational regulation and design achievement
    • Authors: Sanghoon Park; Howard Kaplan, Rudy Schlaf
      Abstract: An interdisciplinary approach can improve both functional and aesthetic design skills for undergraduate engineering students. In this paper, we designed and compared two flipped engineering classrooms, one involving only engineering students who worked on individual design tasks, and the other including groups of an engineering student and an art major student that performed design tasks collaboratively. Fifty-one engineering students, 29 from the individual flipped classroom and 22 from the interdisciplinary flipped classroom participated in the study. During the semester, all students studied pre-recorded video lectures and homework before the class and then participated in weekly engineering design activities either individually or in a group. Students’ motivational experiences and engineering design achievement were assessed at the end of the semester. The results showed that students’ preferences in employing motivational regulation between the two flipped classrooms were different. Also, the students participated in the interdisciplinary flipped classroom exhibited higher aesthetic design achievement.

  • A workbench for motion control experiments using programmable automation
           controllers in industrial automation laboratory at Kongu Engineering
    • Authors: Jegadheesan Chinnasamy; Kiruba Shankar Ramesh Babu, Maheswari Chenniappan, Parameshwaran Rathinasamy
      Abstract: Mechatronics Engineering has become an internationally recognized discipline with degree programmes offered in majority of the universities all around the world. Integrating mechanical, instrumentation, and programmable automation controller (PAC) for developing technical skills and expertise in system level integration to attain manufacturing and controller programming superiority has become the basic requirement for Mechatronics Laboratory. Divulging the graduates to servo control concept down the line to the programmable automation controller helps to gain the practical knowledge in the field of I/O interfacing, closed loop control, remote monitoring, and PLC motion control programming. Hence in this paper, a 3-axis servo control system with HMI work bench case study has been presented to enable the graduates to learn multi-disciplinary concepts in the field of material handling and precise position synchronous control of multi-axis rotating system. With this work bench, applications of servo control such as electronic gearing (positioning), pick and place (material handling), and profiling (welding, machining) can be exposed to mechatronics graduates. Graduates with fundamental programming skills and apparently no-practical experience with mechatronics systems can quickly learn how to incorporate control architectures with this work bench and prepare them to compete in Industry 4.0 environment.

  • Development of a software tool for teaching real-time state simulation of
           water distribution networks
    • Authors: Hui Zhang; Xue Zhou, Luobin Wang, Kai Wang, Wendong Wang
      Abstract: An educational software tool was developed for teaching the real-time state simulation of water distribution networks (WDNs) to municipal engineering students. The weighted-least-square model and Davidon–Fletcher–Powell (DFP) algorithm were used to calculate the state variable values with real-time measurements. The software tool was composed of three modules, including network loading, state simulation, and data management. The program and the relevant graphical user interface were coded using Delphi 7.0. The performance of the software tool was proved to be effective in teaching and learning by two evaluation approaches. Moreover, the positive results also encouraged software developers and lecturers to produce or at least use computer-aided tools for educational purposes.

  • Object-oriented modeling approach of universal education software
    • Authors: Dalibor Petković; Srdjan Jovic, Zoran Golubovic
      Abstract: Since learning process could be very challenging task for scholars in this article an attempt to analyze and model a universal education software (UES) was made. The software was modeled from beginning of the life cycle by object-orientated modeling approach. In order to visually represent any research problem unified modeling language is the most appropriate and efficient tool. In this paper UES was modeled by unified modeling language diagrams which could lead to better development and understanding of the behavior and structure of the software. Modeling by unified modeling language is a new way of thinking about systems and the development process which involved object modeling. The main concept of the object modeling is the object identification within the system environment, and the relationships and interactions between the objects.

  • Applying interactive devices to an elementary nature science course
    • Authors: Chian Wang
      Abstract: The goal of this paper is to design and develop an interactive learning system (ILS) by integrating interactive devices into a real-world classroom. ILS is primarily designed for elementary school students where they can have some hands-on experiences to learn nature science such as airflow and wind. The purpose of adopting interactive devices is to increase students’ motivations and pleasures during the learning process. In order to demonstrate the learning effects of using ILS, an empirical study was conducted by comparing traditional and interactive instructional strategies. During the study, three types of measurements were used to assess the different aspects of ILS: learning achievement tests, a questionnaire about students’ experiences, and teacher interview. The results showed that ILS does have positive effects on students’ learning and we can conclude that ILS can effectively and efficiently assist in learning nature science in a real-world classroom environment.

  • Educational interactive LabVIEW programming of a 3D canal surface design
    • Authors: Faridoun A.M. Allawi
      Abstract: Educational computer programming in geometrical modeling is an interactive dynamic educational method which helps to visualize; interactively and graphically; 3D geometrical models under different design conditions. Students using geometrical modeling in hydraulics can get large amount of geometrical data describing the x, y, and z coordinates of any circular cross-section of the designed 3D canal transition, a step which is very important in the modeling of field and laboratory 3D canal sections. They can visually and interactively perform mathematical analysis of very complicated models very easily. Educational programming of geometrical modeling is very similar to experimental modeling in which the students gets feedback from the computer program and adjust—if necessary—the model specifications and properties to get the best engineering design. In this paper, the LabVIEW Platform and the 3D Bezier surface design method will be used by the students, as an educational interactive computer programming, for the design of a 3D open circular canal cross-section having a hydraulic constriction and, a bottom slope of certain dimensions.

  • A computational approach to support the creation of terminological
           neologisms in sign languages
    • Authors: Celso L. Souza; Flávio L.C. Pádua, Vera L.S. Lima, Anisio Lacerda, Carlos A.G. Carneiro
      Abstract: This work presents a novel approach to support the creation of terminological neologisms (technical signs) for Science, Technology, Engineering, and Mathematics (STEM) dictionaries in sign languages. We propose the use of computational methods to assist the creation of terminological neologisms that will constitute new STEM dictionaries. More specifically, we propose the use of computer vision algorithms for shape extraction and description from the visual representation (illustration) of a signless technical concept, as well as natural language processing methods for determining the stem of its corresponding oral term. By comparing those pieces of information of the signless technical concept with the corresponding ones of general-purpose signs in a repository, our approach creates a meaningful new sign from the existing ones with similar features. As far as we know, this is the first computer-aided proposal to create new signs and deal with the problem of technical vocabulary absence in sign languages, making the process of sign creation more agile and scalable. To validate the created technical signs, an evaluation committee composed by fluent signers considers aspects such as, the phonetic, phonological, and morphological structures of the sign language. Experiments were performed with technical concepts of the architectural drawing area, for which new signs in the Brazilian Sign Language were created. The results are promising with 60% of the new signs being rated on a five-point scale with a similar satisfaction level of signs of a reference dataset.

  • An educational tool for introducing power engineering students with modal
           extraction concepts
    • Authors: Aminadab Córdova-Acosta; Jorge G. Calderón-Guizar, Olivia G. Fragoso-Díaz
      Abstract: Undergraduate power engineering students find difficult to apply modal analysis to characterize the dynamical behavior of a power system, although they know some basic concepts of modal analysis from courses such as linear algebra and differential equations. This paper presents an educational software tool for the identification of dominant oscillatory modes from time domain responses. It is aimed to help power engineering systems students to understand and to gain experience on the application of modal analysis for assessing the system dynamics from measured signals of a power system, in terms its dynamic properties such as oscillation frequency and its associated damping.

  • A feedback system to provide affective support to students
    • Authors: Samantha Jiménez; Reyes Juárez-Ramírez, Víctor H. Castillo, Guillermo Licea, Alan Ramírez-Noriega, Sergio Inzunza
      Abstract: Learning support systems need to provide direct and affective interaction to students; it can encourage them and improve their motivation to learn. However, several systems do not include this kind of interaction between students and tutors. In those cases, the student learning interest and motivation to learn could be negatively affected, and student profits from the system could be impoverished. Only a few works have examined the influence of written affective feedback, but these studies focused on student learning outcomes, not in student motivation to learn. The objective of this work is to analyze the impact of an affective feedback system on the students’ perception of two aspects: (i) the degree to which study time is enjoyable and (ii) the motivation to learn. Results show that the affective feedback system makes more enjoyable study time and motivates students to learn, particularly to students with low academic performance. These system enhancements eventually would improve student-learning outcomes.

    • Authors: Longlong Feng; Hongxia Jiang, Junling Wang, Yunpeng Gong
      Abstract: To overcome geographical restrictions of the cross-registration, this study uses MOOCs and DBL as the learning approach to presents an implementation process of cross-registration in the course of Machinery Design. Cross-registration contains three steps: Pre-Registration, Learning Process, and Credit Certification. According to the characteristics of cross-registration, Learning process was realized through the mode which consists of Massive Open Online Courses (MOOCs) learning, traditional classroom and Design Based Learning (DBL). Project progression of DBL was elaborated, demonstrated and had been applied in cross-registration. This work aims at analyzing and reporting whether this MOOCs and DBL-based cross-registration has effects on a case study in Machinery Design Course. Students’ performance and learning behaviors are analyzed in this article. The results indicate that the MOOCs-based cross-registration is practicable, Learning Process has positive influence on students' performance. Recommendations for future work and implications for practice will also be discussed.

  • Development of structural analysis virtual modules for iPad application
    • Authors: Nicolas Pena; An Chen
      Abstract: Structural Analysis is a course to study structures subjected to different loading conditions, which employs engineering mechanics, material science, and applied mathematics to determine structural deformation, internal forces, and structural support reactions. Without any lab demonstrations, students taking the course miss the opportunity to observe key visual concepts of structural analysis. To address this issue, this paper aims to develop an iPad application, iStructure, which will illustrate and teach key concepts of structural analysis and can be used as an instructional tool for instructors and learning tool for students. iStructure covers three main structural modules: beam, truss, and frame. This paper reports structural analysis methods and computer algorithms used to develop iStructure and its applications. The structural characteristics, such as structural deformation, internal force diagrams, stress and strain diagrams, and influence line are illustrated and simulated within each module using Objective-C programming. The Frame and Truss Modules employ Matrix Structural Analysis methods for determining the conditions of the structure. The modules incorporate a modified and efficient matrix structural analysis procedure through the use of pointer addresses, which avoid developing multiple large matrices for structural analysis by using the DOF indices to develop the global partition matrix directly. This procedure provides faster computation and less memory demands, while making instant structural analysis of relatively complicated structural configurations possible. The Beam Module utilizes a predefined beam formulas method for determining the conditions of the structure. This method significantly reduces the structural analysis computation demand and is necessary for the development of the Influence Line, which requires multiple structural analyses iteration.

    • Authors: Gabrijela Dimić; Bratislav Predić, Dejan Rančić, Vera Petrović, Nemanja Maček, Petar Spalević
      Abstract: The paper suggests the implementation of association analysis for improving the process of e-testing in blended learning environment. The research has been conducted using knowledge tests at the Computer Graphics Moodle Course. In the preprocessing phase, data matrices have been created and prepared for the process of discovering significant relationships and links between students' answers to the questions from preparatory tests and those for testing knowledge, the ways of doing, and achieved results. By implementing Apriori and Predictive Apriori algorithms, a great number of association rules has been discovered. Important and interesting rules have been singled out by implementing objective and subjective assessment measures. The examples of interesting rules, as well as discovered patterns in items' relationships, have also been presented. The contribution of the described case study is visible in providing important feedback which enables the teacher to get a better insight into the concepts of created tests and decide on how to make changes to improve testing.

  • Skill-based education through fuzzy knowledge modeling For e-learning
    • Authors: C. Gomathi; V. Rajamani
      Abstract: Nowadays outcome-based methods are adapted in e-learning system to meet the need of the novel development of e-learning systems for improved web-based retrieval results. Typically, knowledge retrieval process is denoted by the production rule, frame, semantic network, fuzzy logic, predicate logic, and group of skill concept. To get the optimized result in proposed skill-based e-learning, the fuzzy knowledge model is applied. In knowledge retrieval, the fuzzy membership value of the knowledge and the combinations of framed rules are used to acquire the knowledge. The fuzzy techniques are adapted for analyzing the retrieved knowledge concept of individual skills like Inadequate (Ia), Adequate (A), Value added adequate (Vaa), and Integrated skill (I) and in fuzzy inference system in skill-based education provides a decision about the learner community skill set and it promotes the excellence skill through the delivery of the suitable courses to the learners instead of supplying common courses to different skilled persons. In the existing knowledge modeling methods known as the Knowledge Capturing and Modeling, concept map-based knowledge modeling confirm the learners to have known or unknown domain concept. Further, many of the researchers present on the analysis of the learner performances, behavior, learning environment, etc. The proposed paper investigate the individual skill abilities and it is suggested a set of courses in adaptive curriculum and syllabus to the learner and also it adapts andragogy in skill-based education, to model the fuzzy knowledge, the fuzzy membership function and rules are used.

  • Adding practical experience to computer security course
    • Authors: Zarko Stanisavljevic; Pavle Vuletic
      Abstract: Computer security has become one of the core areas according to IEEE Computer Society and ACM Joint Task Force curriculum guidelines for undergraduate degree programs in computer engineering and software engineering. At the University of Belgrade, School of Electrical Engineering there is a course called Computer Security that is taught to software engineering and computer engineering students for the past 9 years. During this time a significant change was made to the course regarding the level of practical students’ work. Several factors initiated the change: the recommendations in the curriculum guidelines, the analysis of the students’ success at the exams, and the students’ opinion. The impact of gradual transition from no practical activities at all to laboratory exercises and practical project at the course are described in this paper. Results show that the introduction of laboratory exercises at the course helped students to better understand some of the core areas and that the introduction of practical project increased their overall knowledge in the computer security area.

  • A low-complexity virtual reality modeling method based on ontology grid
    • Authors: Neng Wan; Zhongliang Deng, Guangyong Yang
      Abstract: This paper focuses on an innovative low-complexity modeling method for virtual reality. Voxels are the basic unit of pixels in 3D (three dimensions), and when stored and processed in a computer, they contain more data redundancy than the demand for actual human vision presentations. This excess is known as voxel redundancy. The reason for the redundancy is that infinite-dimensional expansion and heterogeneous voxel features have merged in modeling methods. The major voxel compressions and human factors correlations are important to consider. Therefore, we propose a novel low-complexity virtual reality based on ontology grid sparsity. The redundancy performance of the existing virtual reality modeling methods is first analyzed. The high-dimension modeling method is designed to describe the base elements that are needed for humans to distinguish what is actually perceived. Based on the ontology theory, grid sparsity is exploited to construct the correlation model. We set up the relevant degree and sensitivity level calculations to classify the correlations between ontology features and other features. The features with weak sensitivity are ignored or merged, which successfully reduces the dimensions and redundancy that are needed to represent virtual items. Visual feature integration combines human factors into a voxel model. Finally, we build the virtual laboratory as a test case in the Unity 3D and 3DMax environment. The tests demonstrate that the new modeling method offers 21.2% and 34.7% of presentation delay and redundancy improvement, respectively.

    • Authors: Zhongyuan Chen; Wanchun Chen, Xiaoming Liu, Chuang Song
      Abstract: This paper presents a hardware-in-the-loop (HIL) simulator, named HIL-GSS, which aims to help the students of aerospace engineering learn control and missile guidance theories effectively by using interactive instrumentation. Electromechanical components and interactive panels are illustrated. Two case-based studies are presented to show the advantages that HIL-GSS offers to engineering education. Steady-state tracking errors of the PID controller based on the HIL-GSS are around zero. The final miss distance in the real-time HIL TV guidance engagement simulation is 0.2376 m. Those results show the reliability of the proposed HIL simulator. In addition, the students' average response to survey questions is 4.22 (1–5 grade scale), which indicates that students strongly agree or agree that HIL-GSS is an effective educational tool.

  • A computer game for teaching and learning algebra topics at undergraduate
    • Authors: Ivan García; Edgar Cano
      Abstract: Technology is increasingly changing the way that engineering students are taught. In recent years, we have witnessed a significant growth in using computer game technologies for teaching and learning in different engineering fields and contexts. This approach offers the ability to create complex and highly interactive scenarios with a solid theoretical basis to teach material in new and highly interactive ways. This paper introduces the application of the game-based learning approach and instructional design for creating a 2D computer game in order to support mathematics teaching and learning in the first-year of an undergraduate engineering course. Additionally, an experiment was conducted on a Computer and Electronic Engineering course to evaluate the effects of the proposed game by following the “competency-based learning” approach on students with sequential and global learning styles. The results showed that the computer game increased the learning experience and motivation of global learners when learning mathematical topics.

  • An efficient speech recognition system for arm-disabled students based on
           isolated words
    • Authors: Khalid A. Darabkh; Laila Haddad, Saadeh Z. Sweidan, Mohammed Hawa, Ramzi Saifan, Sharhabeel H. Alnabelsi
      Abstract: Over the previous decades, a need has emerged to empower human-machine communication systems, which are essential to not only perform actions, but also obtain information especially in education applications. Moreover, any communication system has to introduce an efficient and easy way for interaction with a minimum possible error rate. The keyboard, mouse, trackball, touch-screen, and joystick are all examples of tools which were built to provide mechanical human-to-machine interaction. However, a system with the ability to use oral speech, which is the natural form of communication between humans instead of mechanical communication systems, can be more practical for normal students and even a necessity for arm-disabled students who cannot use their arms to handle traditional education tools like pens and notebooks. In this paper, we present a speech recognition system that allows arm-disabled students to control computers by voice as a helping tool in the educational process. When a student speaks through a microphone, the speech is divided into isolated words which are compared with a predefined database of huge number of spoken words to find a match. After that, each recognized word is translated into its related tasks which will be performed by the computer like opening a teaching application or renaming a file. The speech recognition process discussed in this paper involves two separate approaches; the first approach is based on double thresholds voice activity detection and improved Mel-frequency cepstral coefficients (MFCC), while the second approach is based on discrete wavelet transform along with modified MFCC algorithm. Utilizing the best values for all parameters in just mentioned techniques, our proposed system achieved a recognition rate of 98.7% using the first approach, and 98.86% using the second approach of which is better in ratio than the first one but slower in processing which is a critical point for a real time system. Both proposed approaches were compared with other relevant approaches and their recognition rates were noticeably higher.

  • Edu-Cloud: On-the-fly employability skills as a service
    • Authors: Sonia Shahzadi; Muddesar Iqbal, Tasos Dagiuklas
      Abstract: Twenty-first century global job market competition requires Science, Technology, Engineering, and Mathematics (STEM) university curricula to support both state-of-the-art technical and soft skills learning to improve graduate employment. This necessitates the transformation of the current teaching and learning methodology powered by a social and collaborative platform to provide a social co-learning environment. This social co-learning will provide students with opportunities for self-enrichment while supporting their technical skills and hands-on needs. The platform must also provide the required lab infrastructure for hands-on experimentation. This paper proposes the design and implementation of a cloud based platform called Edu-Cloud. The Edu-Cloud has been designed to provide automated resource provisioning and perform on-the-fly deployment of scalable virtual network functions to stream multimedia content closer to the global learners. This would help to meet the specific learning needs of a group of global interconnected students with similar learning skills and abilities. The benchmarking performance results show that the proposed framework works efficiently while reducing primary network traffic by deploying resources closer to the users and support scalability for a global deployment scenario.

      Abstract: SEED is a software tool designed for Java consisting of a class library and a set of simulators to facilitate learning of the main data structures. The educational component is based on an active case-solving methodology accompanied by a pedagogical strategy. This strategy allows for the development of a multilayer-model-programming work for the construction of basic and advanced applications in real domains and for integration of its use, development and operation assessment with data structures. The evaluation results of SEED as a pedagogical mediator in the issue of binary trees is presented. The evaluation indicates that students prefer to use SEED due to its simplicity and attractive GUIs which facilitate data structures learning.

  • ADAMS as an aid for teaching undergraduate dynamics
    • Authors: Satanik Mukherjee; Sumanta Neogy, Arghya Nandi
      Abstract: The objective of the present work is to use multi body dynamics package (like MSC Adams) for motivating undergraduate students in a Dynamics course by means of simulations—a step which lies between traditional board work and actual experimentation. It also deepens his understanding of mechanics by allowing him to compare ADAMS solution with manual solution and solution obtained through small user developed program segments. The student learns to appreciate why the manual solutions are specialized cases of general solutions and how and why trajectories are determined. In the process it discusses the logical structure of Dynamics as implemented in these packages. Such an approach would also introduce them to such powerful tools at an early stage. It provides detailed solution of three problems using Adams and brief solutions to eight more. It is expected once these examples are mastered, most of the problems in undergraduate dynamics can be tackled using Adams.

      Abstract: The rapid development of fast, powerful, and affordable computer technology has provided educators options to introduce innovations in teaching and learning process. The purpose of this study is to investigate the effect of computational simulations on students' understanding of marine mooring line tension in ocean engineering course. Instructional strategies need to incorporate mathematical and computational knowledge into their practice project so that students can use its core concepts to solve interdisciplinary problems. By writing students own Matlab program, students will demonstrate the effect of mathematical and computational tools on the analysis of ocean structural dynamics. The effectiveness of instructional methods by investigating learning gains, instructional effect, and student perceptions about the course are evaluated. Through the teaching practice, students significantly increase their understanding of ocean engineering concepts.

      Abstract: Online learning platforms are becoming increasingly popular in engineering education. Through combining the educational form of online learning with laboratory information management systems (LIMS), we can integrate the education and management functions into one system. The purpose of this study is to develop a collaborative education and management system for the water hydraulic laboratory based on the Hypertext Preprocessor (PHP) scripting language. The system provides a convenient and multifunctional education and management platform for students and teachers throughout the whole experiment courses. Additionally, the B/S (Brower/Server) structure based on the Model-View-Controller (MVC) model was used in our system. The key steps of developing the WathyLab system were described, and the practical application subjects regarding water hydraulic materials were illustrated. The paper ends with an evaluation of this system according to the questionnaire survey. The students’ attitudes were surveyed and analyzed. Results showed that the proposed system can lead to better education effectiveness and learning efficiency.

  • Video podcast and illustrated text feedback in a web-based formative
           assessment environment
    • Authors: Emilio Letón; Elisa M. Molanes-López, Manuel Luque, Ricardo Conejo
      Abstract: It is well known that computer-based formative assessment and timely feedback enhance effective student learning but there is still a debate about what type of feedback should be given, being the text-based the most used feedback in practice. Although the use of video content as a learning resource has recently increased in both educational and non-educational contexts, there is very little research on its effectiveness as assessment feedback and the existing results are contradictory. For that reason, we have combined in this work the use of a web-based formative assessment system (Siette) where we have integrated a specific type of video podcast (“modular teaching mini-videos”: MTMs) and equivalent illustrated text. We have carried out two experiments with a twofold purpose, first to compare the effect of video feedback versus correct response feedback alone and secondly to compare the effect of video feedback versus equivalent illustrated text feedback. In the context of our research, a Statistic Course at university level, our results show, as expected, that there is a statistically significant positive effect in favor of video feedback over correct response feedback alone. Surprisingly, in contrast to our expectations, based on our context of acquisition of procedural knowledge, there is a statistically non-significant effect of video feedback versus equivalent illustrated text feedback. From the students’ satisfaction survey, there is not statistically significant differences in the overall score of the activity based on video podcast feedback or equivalent illustrated text, which is an indication that we have really obtained equivalent feedback materials.

      Abstract: At present, one of the main problems which can be found within chemical engineering education is the availability of real industrial plants able to provide an experimentation framework. The importance of this kind of plants lies in allowing students to apply the learned theoretical concepts to solve real problems. In this paper, a remote tool for educational purposes is presented. More specifically, the implementation of a four-tank plant, its internal control design and the implementation of an EasyJava tool for executing JavaScript code in both simulation and real experimental tests have been widely described. As a result, a tool that allows to perform experimental tests over the plant in both real and simulation modes has been obtained. In this tool, the limits of use are imposed by the plant and not by the own tool.

  • Correctness assessment of a crowdcoding project in a computer programming
           introductory course
    • Authors: Sebastián Ferrán; Alejandra Beghelli, Gonzalo Huerta-Cánepa, Federico Jensen
      Abstract: Crowdcoding is a programming model that outsources a software project implementation to the crowd. As educators, we think that crowdcoding could be leveraged as part of the learning path of engineering students from a computer programming introductory course to solve local community problems. The benefits are twofold: on the one hand the students practice the concepts learned in class and, on the other hand, they participate in real-life problems. Nevertheless, several challenges arise when developing a crowdcoding platform, the first one being how to check the correctness of student's code without giving an extra burden to the professors in the course. To overcome this issue, we propose a novel system that does not resort to expert review; neither requires knowing the right answers beforehand. The proposed scheme automatically clusters the student's codes based solely on the output they produce. Our initial results show that the largest cluster contains the same codes selected as correct by the automated and human testing, as long as some conditions apply.

  • An educational software to reinforce the comprehensive learning of
           materials selection
    • Authors: Alvaro Rodríguez-Prieto; Ana M. Camacho, David Merayo, Miguel A. Sebastián
      Abstract: An educational software, called CalSev 1.0.2, has been developed for supporting the teaching in materials selection seminars. As a case study, a selection of materials for nuclear reactor pressure vessels has been chosen, because it is a representative example of the relationship between chemical composition, mechanical properties, and in-service behavior. This software has been developed to improve the students’ understanding of the materials selection tasks, providing an interactive user-friendly platform that allows to modify—in real time—the content of chemical elements and mechanical requirements to obtain a materials performance evaluation. Due to its versatility, this informatics tool represents a great value for educational purposes, with special impact in blended and distance learning, by simplifying the arduous task of materials selection for a wide range of applications and promoting a collaborative working environment by easing the creation of small groups analyzing different study cases. Finally, to evaluate the functionality, interest, user-friendliness and the educational characteristics of CalSev 1.0.2, a survey among 36 undergraduate students has been carried out.

  • Multi-DGAS: A pattern based educational framework design for power
           transformers faults interpretation and comparative performance analysis
    • Authors: Metin Varan; Ulaş Yurtsever
      Abstract: Taking necessary measures in advance for early prediction of the transformer failures are very crucial. Dissolved gas in oil analysis (DGA) techniques that used in electrical power systems has become an internationally accepted standard in condition based maintenance (CBM) studies have high complexity and increasing demands of the quick-service-ready paradigm in power transformers. This standard includes the implementation steps of various complex DGA methods named basic gas, Rogers, Doernenburg, Duval triangle, and pentagon. Mentioned methods are quite complicated and their application steps are strict rules defined in detailed procedures. The adaptation of these methods to transformer maintenance procedures that prepared according to standards and tested for correctness creates a valuable tool. In this study, a pattern based educational framework has been designed to integrate state of arts DGA techniques help for trainers, graduate researchers working on DGA techniques, and also for maintenance teams while taking critical decisions on power transformers. Developed Multi-DGAS educational framework is designed for modular construction that can be integrated with online condition monitoring and diagnostic systems for electric power systems. Success of the proposed framework revealed with newly proposed pentagon method in regard with comparison of classical methods by using oil samples which have been taken under the energized condition of different 135 transformers within multi-phase which failure histories already known. Analysis of dissolved gases in transformer oil is performed according to ASTM-D 3612 procedure using 3800 GC Varian gas chromatograph apparatus.

The system provides users with two kinds of walkthrough modes, demonstration of the structure and operation principle of some main equipment as well as the operating functions of setting up some major pumps and valves so as to strengthen the students’ understanding of the chemical process and train their operative ability. In addition, its virtual treatment of emergency can help to enhance the safety production awareness of the students and cultivate their ability to respond to unexpected emergency. The students’ feedback to our survey indicates that, despite some suggestions for further improvement, the virtual platform has more advantages and characteristics compared with traditional practice mode, and is effective in helping them understand the chemical process and equipment. What is more, some improvement has been made to perfect the system with students’ suggestions fully taken into consideration.

  • Design and implementation of a real-time monitoring tool for power
           engineering education
    • Authors: Juan S. Rocha-Doria; Octavio A. Mosquera-Arevalo, César Angeles-Camacho, Alvaro Espinel-Ortega, Jorge G. Calderón-Guizar
      Abstract: This article reports on the implementation of a real-time monitoring system in a laboratory test grid based on synchrophasorial measurement units. The system consists of the installation of different types of units for monitoring the electrical parameters of the network. The information is transmitted to a power data concentrator equipment, through a local area network under TCP/IP protocol. All the information received is properly processed and systematically stored for future use. A graphical application was developed to visualize the information in real- time or to perform off-line power analyses. The functionality of the monitoring system was verified on several test grids and is used for teaching and research for both undergraduate and postgraduate students in the power electronics laboratory at the Engineering Institute of the Universidad Nacional Autónoma de México.

  • Exploring the effectiveness of continuous activity with automatic feedback
           in online calculus
    • Authors: Teresa Sancho-Vinuesa; Ramon Masià, Marc Fuertes-Alpiste, Núria Molas-Castells
      Abstract: Academic results in mathematics subjects in engineering, especially those taught online, are poor. The key contextual elements of an insufficient level of prior knowledge, poor motivation, and the intrinsic difficulty of the subject matter has led to the review of the study materials and the creation of a methodology based on continuous assessment with automatic feedback at the Universitat Oberta de Catalunya. The main objective of this article is to present evidence of improved learning outcomes with the application and use of WIRIS quizzes as an automatic assessment tool in calculus subjects. To that end, we carried out descriptive research with an ex-post-facto design, based on statistical analysis of the results for continuous assessment and students’ grades in 11 semesters. The new strategy has been applied in the last two academic years, based on introductory Moodle lessons and assessment with interactive questionnaires. The data obtained are inconclusive: In the first two semesters that the methodology was implemented, the results show a noticeable improvement in several key aspects, such as undertaking and passing the continuous assessment and improved results across the spectrum of grades. However, in the last two semesters, the results are generally similar to those obtained with the old methodology.

  • Visual presentation of abstract theoretical concepts using animations in
           communication systems courses
    • Authors: Stevan M. Berber; Kevin W. Sowerby
      Abstract: A new approach to teaching Communication Systems course is proposed, which is based on the use of animations as a complement to the lecture material. The animations are designed to visualize abstract mathematical concepts, related to modulation techniques and communication system analysis in presence of noise, and present these concepts to the students in visual and understandable form in the classroom. The animations have double purpose. They are to be used, firstly, by the lecturers during lecture presentations, and secondly, as an additional aid to the students to support their self-learning activity. The animations are developed on MATLAB platform.

  • RTWiFi-Lab: A real-time Wi-Fi laboratory platform on USRP and LabVIEW for
           wireless communications education and research
    • Authors: Kerem Küçük
      Abstract: The paper presents the real-time education and research platform as an effective means for describing wireless and digital communications courses with Wi-Fi standards. To this end, a Real-Time Wi-Fi Laboratory platform, called RTWiFi-Lab is designed and implemented as part of these courses using NI USRP 2921 and LabVIEW. Laboratory experiments of these courses give benefits for utilizing a hardware platform since these experiments greatly facilitate the understanding of significant effects introduced by real-time receivers. Hence, this platform is presented with seven experiments that provide the various concepts of these courses for different state-of-the-art wireless and digital communications techniques such as signal detection, data modulation, frequency, phase offset estimation, etc. The RTWiFi-Lab has been considered to provide computer engineering undergraduate students and qualified graduate students with the basic introduction to wireless and digital communications concepts in a short time at Kocaeli University, Turkey.

  • Euler algorithm to solve reaction kinetic equations: Mathematical
           formulation, programing, and applications
    • Authors: Baudilio Coto; Inmaculada Suárez
      Abstract: Integration of rate laws to obtain the several concentrations in terms of time is well described in books of General Chemistry, Physical Chemistry, or Chemical Engineering including mathematical and graphical descriptions. When several reactions have to be considered simultaneously, the mathematical solution of involved differential equations became difficult for students and is a good task from the mathematical point of view. Qualitative interpretation has interest from the chemical and engineering point of view and it is usually related with the change of concentrations along reactions which in turns modifies the rate of the several processes involved. In this work, no differential equations are solved analytically and no functions are obtained in order to reduce the mathematical complexity for students but a numerical solution is obtained by using the differential method and the computation of changes in concentration. A general formulation of the involved equations is presented including the effect of reactant concentration in the rate laws and an arbitrary number of simultaneous reactions. Details for numerical solution of involved equations are indicated and the task for students is to create their own program to solve the rate laws. Student should be able to input a set of compounds and reactions, to compute the evolution of concentrations of the several species with time and to plot such concentrations. Some applications with increasing complexity were computed and analyzed. In order to show the quantitative obtained results, comparison with analytical functions was carried out for simple systems.

  • A hybrid method for overlapping speech detection in classroom environment
    • Authors: Dazhi Jiang; Yifei Chen, Akhil Garg
      Abstract: Classroom discourse, which is a major composition of classroom, contains a slew of useful information such as providing the feedback to the teachers may lead to an improvement of the teaching quality. Generally, the classroom discourse can be divided into four categories/activities: teacher discourse, student discourse, quiet, and discussion. The automatic classification of activities provides a practical way to deal with the classroom discourse. However, the recognition of the discussion activity (a kind of overlapping speech) poses a great challenge to the treatment of the classroom discourse analysis. Therefore, in this paper, a new hybrid method based on the silence distribution and Independent Component Analysis (ICA) was proposed for the detection of overlapping speech. The results were found to be satisfactory and in good agreement with an experimental data. Based on these experimental results, the performance of the speaker segment of classroom event can be efficiently analyzed.

  • Peer learning efficacy analysis on undergraduate software design course
    • Authors: Po-Hsun Cheng; Li-Wei Chen
      Abstract: Knowledge sharing and peer learning are important characteristics for learning similar engineering topics, especially suitable for the learning in college. Software design is an advanced required course for software engineering departments. However, most students might have no enough incentives to learn it by themselves. To distinguish the performance of the peer learning, we adopted the peer learning in software design course to analyze the possibility of adoption. Our selected course was a junior major and held on the second semester. Its regulations are declared twice before the due date of the course selection. Students can group their peer learning team by at most three ones, so they can choose as individual learning. Both review and summary quizzes were held at the first and the last 15-min in the Moodle every week, respectively. There were 34 students attending this experiment with four 3-student groups, five 2-student groups, and 12 singles. A web-based tool was designed to illustrate the peer learning performance and students can browse their own score analysis anywhere. Inside the experimental weeks, we found most students attend the course on time. Though the effect of the adopted approach (may be due to too few samples) is not clear, we found evidence from the descriptive statistics and detailed analyses of the experiment results. The peer learning by grouping could have large chance to be better than individual study. It encourages us to adopt the same educational practice to our software design course, even other software related courses.
