  • A Systematic Review of Empirical Studies on Learning Analytics Dashboards:
           A Self-Regulated Learning Perspective
    • Authors: Wannisa Matcha;Nora'ayu Ahmad Uzir;Dragan Gašević;Abelardo Pardo;
      Pages: 226 - 245
      Abstract: This paper presents a systematic literature review of learning analytics dashboards (LADs) research that reports empirical findings to assess the impact on learning and teaching. Several previous literature reviews identified self-regulated learning as a primary focus of LADs. However, there has been much less understanding how learning analytics are grounded in the literature on self-regulated learning and how self-regulated learning is supported. To address this limitation, this review analyzed the existing empirical studies on LADs based on the well-known model of self-regulated learning proposed by Winne and Hadwin. The results show that existing LADs are rarely grounded in learning theory, cannot be suggested to support metacognition, do not offer any information about effective learning tactics and strategies, and have significant limitations in how their evaluation is conducted and reported. Based on the findings of the study and through the synthesis of the literature, the paper proposes that future research and development should not make any a priori design decisions about representation of data and analytic results in learning analytics systems such as LADs. To formalize this proposal, the paper defines the model for user-centered learning analytics systems (MULAS). The MULAS consists of the four dimensions that are cyclically and recursively interconnected including: theory, design, feedback, and evaluation.

  • An Agent-Based Simulator Applied to Teaching-Learning Process to Predict
           Sociometric Indices in Higher Education
    • Authors: Iván García-Magariño;Inmaculada Plaza;Raúl Igual;Andrés S. Lombas;Hana Jamali;
      Pages: 246 - 258
      Abstract: Most novice teachers and even some experienced teachers can lack appropriate tools for designing teaching strategies that ensure the quality of education. The ability of working in teams is crucial in educating professionals. The literature proves that social relations influence the performance of teams. For instance, the team cohesion is directly related with its performance. In this paper, we have developed an agent-based tool for assisting teachers in simulating their teaching strategies to estimate their influence on the group sociometrics like cohesion, coherence of reciprocal relations, dissociation, and density of relations. The experiments with nine scenarios in disciplines of computer science, electronic, psychology, business, tourism, and renewal energies with 239 students and 6 teachers including experienced and novice ones show that its underlying agent-based framework can adapt to different disciplines obtaining similar outcomes to the real ones. We learned that the tool was especially reliable in predicting the density of relations and the cohesion, being the latter one probably the most relevant due to its known relation with academic performance. In addition, we also learned that it was difficult to assess the prediction quality of the dissociation in higher education, due to the usual low amounts or absence of reciprocal rejections in the students’ groups in this educational stage. The presented agent-based tool is publicly distributed as open source for facilitating other researchers in following this research line.

  • An Augmented Paper Game With Socio-Cognitive Support
    • Authors: Yun Wen;
      Pages: 259 - 268
      Abstract: This paper presents an augmented reality-based Chinese character composition game (ARC) that employs augmented papers to engage lower primary school students in collaborative Chinese character learning. A design research approach was used to gain a holistic view of designing, enacting, and evaluating the ARC. The participants included four teachers and five classes of students from two primary schools. The school-based research findings suggested that: 1) the ARC was an effective system for improving beginning learners’ orthographic knowledge of Chinese characters, particularly for those students with low Chinese language proficiency; 2) the tangible paper interface engaged students in group work and increased the game playfulness; and 3) students’ language proficiency had a significant effect on their perceptions of ease of use and usefulness of the augmented paper game. This paper not only substantiated the potential of the augmented paper as a carrier of educational content, but also instantiated how to implement it to promote social and cognitive supports for interaction and collaboration.

  • Assessing Pronunciation Improvement in Students of English Using a
           Controlled Computer-Assisted Pronunciation Tool
    • Authors: Cristian Tejedor-García;David Escudero-Mancebo;Enrique Cámara-Arenas;César González-Ferreras;Valentín Cardeñoso-Payo;
      Pages: 269 - 282
      Abstract: Over the last few years, we have witnessed a growing interest in computer-assisted pronunciation training (CAPT) tools and the commercial success of foreign language teaching applications that incorporate speech synthesis and automatic speech recognition technologies. However, empirical evidence supporting the pedagogical effectiveness of these systems remains scarce. In this article, a minimal-pair-based CAPT tool that implements exposure–perception–production cycles and provides automatic feedback to learners is tested for effectiveness in training adult native Spanish users (English level B1–B2) in the production of a set of difficult English sounds. Working under controlled conditions, a group of users took a pronunciation test before and after using the tool. Test results were considered against those of an in-classroom group who followed similar training within the traditional classroom setting. Results show a significant pronunciation improvement among the learners who used the CAPT tool, as well as a correlation between human rater's assessment of posttests and automatic CAPT assessment of users.

  • Augmented Immersive Reality (AIR) for Improved Learning Performance: A
           Quantitative Evaluation
    • Authors: Ling Cen;Dymitr Ruta;Lamees Mahmoud Mohd Said Al Qassem;Jason Ng;
      Pages: 283 - 296
      Abstract: Technology-enhanced learning has attracted increasing attention of educational community focused on improvement of traditional classroom learning. Augmented immersive reality (AIR) technologies enhance users’ perception of reality by augmenting it with computer-generated components such as audio, video, 2/3-D graphics, GPS data, etc. The AIR introduces new dimensions of learning experience that ensure better attention, focus, and entertainment, thereby boosting students’ motivation and attainment. This work presents an award winning AIR-based educational mobile system, code-named AIR-EDUTECH, that was developed to help high school students learn chemistry. The AIR-EDUTECH introduced new AIR features to help students better understand and learn basic concepts of molecular chemistry. It offers immersive 3D visualization and visual interaction with the examined structures that provides a broader and more retentive knowledge and improves intuition around forming basic chemical reactions. The system was introduced and tested in a field study with 45 students in the $11^{th}$ grade chemistry class, and its impact was evaluated by the formal assessment quiz along with the feedback from survey conducted after the trial. Collected data have been subjected to an in-depth multi-modal quantitative analysis that revealed that AIR-EDUTECH stimulated significant improvements in understanding and retention of the taught content as well as turned learning chemistry into a fun, interesting and interactive experience. It also uncovered a hidden structure of taught knowledge dependencies and highlighted the role that AIR technology could play in reinforcing the retention of critical knowledge that may otherwise widen student knowledge gaps.

  • Automatic Syllabus-Oriented Remixing of Open Educational Resources Using
           Agent-Based Modeling
    • Authors: Maedeh Mosharraf;Fattaneh Taghiyareh;
      Pages: 297 - 311
      Abstract: Rapid development of open educational resources (OER) is often motivated by a new educational paradigm. This paradigm tends to address current challenges such as reusing, goal-oriented remixing, revising, and redistributing OER. This paper proposes a system to automatically remix, which is a step towards automatic course generation. This system uses an agent-based modeling (ABM) approach to profile OER and simulate the process of selecting and linking the appropriate ones. Each resource profile provides us with metadata that shows its domain and is completed using an appropriate ontology before agents’ interactions. ABM enables cooperation between OER to satisfy requirements of the input syllabus. Using the interaction ability, the most compatible agents, which cover the concepts of the input syllabus, can be linked. The efficiency of the proposed method is evaluated through applying the implemented system on two datasets: ARIADNE and SlideShare. In our experimental results on OER related to the domain of e-learning, we report on the system precision and user satisfaction. Our approach is generic; it can be used with any OER repository and any content management system with a free reuse and remix license.

  • DeepStealth: Game-Based Learning Stealth Assessment With Deep
           Neural Networks
    • Authors: Wookhee Min;Megan H. Frankosky;Bradford W. Mott;Jonathan P. Rowe;Andy Smith;Eric Wiebe;Kristy Elizabeth Boyer;James C. Lester;
      Pages: 312 - 325
      Abstract: A distinctive feature of game-based learning environments is their capacity for enabling stealth assessment. Stealth assessment analyzes a stream of fine-grained student interaction data from a game-based learning environment to dynamically draw inferences about students’ competencies through evidence-centered design. In evidence-centered design, evidence models have been traditionally designed using statistical rules authored by domain experts that are encoded using Bayesian networks. This article presents DeepStealth, a deep learning-based stealth assessment framework, that yields significant reductions in the feature engineering labor that has previously been required to create stealth assessments. DeepStealth utilizes end-to-end trainable deep neural network-based evidence models. Using this framework, evidence models are devised using a set of predictive features captured from raw, low-level interaction data to infer evidence for competencies. We investigate two deep learning-based evidence models, long short-term memory networks (LSTMs) and n-gram encoded feedforward neural networks (FFNNs). We compare these models’ predictive performance for inferring students’ knowledge to linear-chain conditional random fields (CRFs) and naïve Bayes models. We perform feature set-level analyses of game trace logs and external pre-learning measures, and we examine the models’ early prediction capacity. The framework is evaluated using data collected from 182 middle school students interacting with a game-based learning environment for middle grade computational thinking. Results indicate that LSTM-based stealth assessors outperform competitive baseline approaches with respect to predictive accuracy and early prediction capacity. We find that LSTMs, FFNNs, and CRFs all benefit from combined feature sets derived from both game trace logs and extern-l pre-learning measures.

  • Design Tradeoffs of Interactive Visualization Tools for Educational
    • Authors: Martina Angela Rau;Will Keesler;Ying Zhang;Sally Wu;
      Pages: 326 - 339
      Abstract: Instruction in most STEM domains uses visuals to illustrate complex problems. During problem solving, students often manipulate and construct visuals. Traditionally, students draw visuals on paper and receive delayed feedback from an instructor. Educational technologies have the advantage that they can provide immediate feedback on students’ visuals. This feedback allows students to learn visualization conventions and to learn new content knowledge. This paper presents a design-based research approach to develop visual tools for an educational technology for chemistry. In this research, three design tradeoffs emerged: (1) Which aspects of the drawing task should visual tools constrain' (2) How should visual tools account for variability in students’ prior experiences' (3) How should the design of multiple visual tools be aligned so that students can easily transition between them' Our design-based research approach comprises three studies that address each of these design challenges in the context of chemistry visualizations. Our studies yield principles for the design of interactive visual tools for educational technologies.

  • Fidelity in Simulation-Based Serious Games
    • Authors: Xiaozhen Ye;Per Backlund;Jianguo Ding;Huansheng Ning;
      Pages: 340 - 353
      Abstract: The extensive use of simulation-based serious games (SSGs) has made a revolution in educational techniques. As a potentially significant feature for SSG design and evaluation, the term fidelity (the similarity between an SSG and its real reference) emerges and attracts increasing attention. The study of fidelity not only benefits the design, development, and analysis of an SSG with the consideration of improving the learning effect but also contributes to the investment reduction of an SSG. However, the term fidelity is used inconsistently in the current literature. The introduction of new technologies (e.g., virtual reality) and the blend of multiform SSGs also facilitate the extension of fidelity with new connotations. All lead to confusing concepts and vague measure metrics. Besides, the relationship between fidelity and learning effect is still uncertain. A new vision and a comprehensive conceptual framework of fidelity for more general applications are in need. In this paper, further exploration and discussion of these issues in relation to fidelity of SSGs are presented through a systematic review. A general conceptual framework considering both aspects of the SSG system itself and the learners is developed and applied to analyze fidelity in SSGs. Based on that, a discussion on fidelity-related issues of SSG design and development is presented.

  • Measuring Similarity of Educational Items: An Overview
    • Authors: Radek Pelánek;
      Pages: 354 - 366
      Abstract: A measure of similarity of educational items has many applications in adaptive learning systems and can be useful also for teachers and content creators. We provide a thorough overview of approaches for measuring item similarity. We document the computation pipeline, explicitly highlighting many choices that have to be made in order to quantify item similarity. We also discuss methods for the analysis of similarity measures. For illustration and evaluation, we consider items from diverse domains, e.g., mathematics, programming, and language learning. Although there is no ultimate, universal approach to measuring item similarity, our overview leads to guidelines that facilitate computation of item similarity in practical applications.

  • MEUS: A Mobile E-Learning Platform for Ultrasound Image Education
    • Authors: Wan-Ching Lien;Phone Lin;Hong-Wun Chen;Herman Chih-Heng Chang;Chia-Peng Lee;
      Pages: 367 - 373
      Abstract: Recently, ultrasound has been increasingly used in emergency departments (EDs) due to its promising noninvasive and portable characteristics. Traditional ultrasound training is a complex process that requires knowledge gain, development of psychomotor skills, and visual perception. However, it usually takes a long time for a novice sonographer to finish an ultrasound training program, and the training may target on limited applications. The e-learning, information, and communication technology on digital devices to support learning may overcome the limitations of the traditional ultrasound training. In this article, we design and implement a mobile e-learning platform for ultrasound training, namely MEUS, to address the abovementioned issues. The MEUS provides an interactive learning environment for teachers and learners. Teachers and learners can access MEUS and receive real-time feedback anywhere and anytime through a mobile device or desktop. We implement a multistage learning process. To evaluate the learning performance of using the platform, we add the MEUS platform as a part of the emergency ultrasound training course with the Post Graduate Year (PGY) program in the ED at the National Taiwan University Hospital. Our study shows that the MEUS platform can significantly increase the learning efficacy of the PGY students.

  • Motivating Students in Collaborative Activities With Game-Theoretic Group
    • Authors: Zacharoula Papamitsiou;Anastasios A. Economides;
      Pages: 374 - 386
      Abstract: Recommending educational resources to groups of students is a common task in collaborative learning contexts. However, differences in within-group motivational factors might lead to conflicts in students’ intention to use the resources. Previous methods fail to achieve high goodness of recommendation for the majority of students in heterogeneous groups. This study demonstrates a game-theoretic solution for recommending educational resources to homogeneous and heterogeneous groups. The group members are the players, the resources comprise the set of possible actions, and selecting those items that will maximize all students’ motivation in the collaborative activity is a problem of finding the Nash Equilibrium (NE). In case the NE is Pareto efficient, none of the players can get more payoff (motivation) without decreasing the payoff of any other player, indicating an optimal benefit for the group as a whole. The suggested approach was empirically evaluated in a controlled experiment with a real dataset. The relevance of each delivered item to its corresponding students was explored both from the perspective of the group and its the individual students. The accuracy of the predicted group/individual motivation, the goodness of the ranked list of recommendations, and the problem-solving performance for the treatment group were significantly higher compared to the control groups. Limitations of the approach, as well as future work plans conclude the paper.

  • Recommender Systems and Scratch: An Integrated Approach for Enhancing
           Computer Programming Learning
    • Authors: Jesennia Cárdenas-Cobo;Amilkar Puris;Pavel Novoa-Hernández;José Angel Galindo;David Benavides;
      Pages: 387 - 403
      Abstract: Learning computer programming is a challenging process. Among the current approaches for overcoming this challenge, visual programming languages (VPLs), such as Scratch, have shown very promising results for beginners. Interestingly, some higher education institutions have started to use VPLs to introduce basic programming concepts, mainly in CS1 courses. However, an important issue regarding Scratchs usage in higher education environments is that students may feel unmotivated being confronted by programming exercises that do not fulfill their individual expectations. To try and overcome this barrier, we propose CARAMBA, a Scratch extension including an exercise recommender system. Based on features, such as taste and complexity, CARAMBA is able to personalize student learning with Scratch by suitably suggesting exercises for students. An in-depth evaluation was conducted about the effects of our proposal on both the learning of basic concepts of CS1 and the overall performance of students. We adopted an equivalent pretest-posttest design with 88 college students at an Ecuadorian university. Results confirm that recommending exercises in Scratch had a positive effect on students programming learning abilities in terms of pass rates. In totality, the pass rate achieved by our proposal was over 52%, which is 8% higher than the rate achieved during a previous experience using only Scratch (without recommendation) and 21% higher than the historical results of traditional teaching (without Scratch). Furthermore, we analyzed the degree of exploitation of CARAMBA by students to portray two facts: students actually used CARAMBA and there was a significant, positive correlation between the utilization of CARAMBA and the scores obtained by the students.

  • Self-Organized Laboratories for Smart Campus
    • Authors: Alberto Huertas Celdrán;Félix J. García Clemente;Jacobo Saenz;Luis De La Torre;Christophe Salzmann;Denis Gillet;
      Pages: 404 - 416
      Abstract: A smart campus provides students who are geographically scattered with online tools to get access to learning resources and laboratories. Although these remote laboratories have the potential and capabilities to implement different learning experiments, most of them are configured in a static fashion, being able to serve only one experiment for a given period of time. This lack of adaptability and flexibility causes long waiting queues of students in certain overloaded remote laboratories, while others are underused. To overcome this limitation, a smart campus can incorporate new techniques and paradigms such as Network function virtualization (NFV) and Software-defined networking (SDN), which are rapidly modifying current cloud services and applications to provide autonomous and adaptive solutions. In this context, the main contribution of this paper is an SDN/NFV-based architecture with autonomic capabilities to adapt to the remote laboratories configuration according to the end-user demand. The proposed architecture will be able to optimize computing resources to ensure the users’ quality of service in a smart campus with remote laboratories. A use case with a remote laboratory, based on the control of a servo motor, shows how our solution can dynamically change the lab service under specific circumstances. Finally, experiments using diverse configurations and service descriptions show the performance and suitability of the proposal.

  • Supporting the Learning of Evolution Theory Using an Educational Simulator
    • Authors: Josué Cardoso;Diego Caetano;Raphael Abreu;João Quadros;Joel dos Santos;Eduardo Ogasawara;Leonardo Lignani;
      Pages: 417 - 424
      Abstract: This paper analyzes Sim-Evolution, an educational simulator designed to help teachers presenting three basic principles of the theory of evolution by natural selection (TENS): the trait variation within a population, the heritability of trait variation, and the selective survival based on heritable traits. Sim-Evolution focuses on high school students, so its interface was designed to be joyful, helping to engage them. Although it was designed based on the concept of population genetics, knowing it is not a requirement for exploring TENS. Sim-Evolution models the population of a hypothetic bird species in two possible vegetations: forest or veld. Individuals of this bird species vary over two characteristics (color and beak type), with three possible phenotypes for each one. The user can choose individuals to form an initial population and monitor variation through successive generations. Birds breed independently of their phenotype, and natural selection (based on the fitness of each trait) was the only driven factor of population variation. Sim-Evolution was evaluated with high school students during a biology class. Students were able to describe and analyze the simulation process from a scientific perspective, observing the phenomenon associated with TENS. They correctly associated the bird's evolution with different survivor rates associated with the different traits and identified evolution by natural selection as a population and not an individual/organism process. Our proposal opens the possibility that TENS simulator does not obligatorily require users to be familiar with population genetics concepts, which is especially interestingly for high school pedagogical uses.

  • There are Open Learner Models About!
    • Authors: Susan Bull;
      Pages: 425 - 448
      Abstract: This overview outlines key issues in learning with an open learner model (OLM). Originally, learner models remained hidden, as their primary role was to enable a system to personalize the educational interaction. Opening the model in an understandable form provides additional methods of prompting reflection, planning, and other metacognitive activities that are important in learning. Learner-system discussion, editing or other interaction about the learner model can allow users to contribute more directly to the modeling process to increase its accuracy, while at the same time, further facilitating reflection as they justify their viewpoints to themselves and the system. Social learning can be supported by opening learner models to peers, helping learners to gauge their relative progress, and effectively seek collaborators. OLMs can also provide useful information to others supporting the learning process, such as teachers and parents. OLMs are set to take an increasing role as new learning technologies develop.
