Secondary school students’ perception according to their learning style
of a mathematics Flipped Classroom
- Authors: Vicent Fornons, Ramon Palau, Raúl Santiago
  Pages: 227 - 244
  Abstract: The Flipped Classroom (FC) has been gaining prominence over the past few years. Many articles have shown that the FC increases the interaction between students and between the teacher and students, allowing different learning rhythms, facilitating access to materials, increasing collaboration between students and enhancing active learning. The present research looks at how students perceive the FC based on their learning style. The research was carried out with a sample consisting of two groups of third-year compulsory secondary education students (37 students in total) in the subject of mathematics. A quantitative methodology was used. At the beginning of the term, all students were given a questionnaire (CHAEA) to determine their learning style. At the end of term they were given a questionnaire (Driscoll) on their perception of the FC . The results show that students with a theoretical style of learning value the uses of the FC more positively and perceive greater interaction with peers and the teacher. However, students with a reflective learning style rate the FC lowest and have a the worse perception of the different key characteristics of the FC. In all statements, most students answered that they agree or very agree. These results are in line with those obtained by other authors in other contexts. This study brings certain nuances to the existing literature on the perception of the FC based on the students’ learning style.

How classroom acoustics influence students and teachers: A systematic
literature review
- Authors: Jordi Mogas Recalde, Ramon Palau, Marian Márquez
  Pages: 245 - 259
  Abstract: Acoustics in schools have been studied during years, but nowadays there are more possibilities than ever before to introduce improvements. This study presents a systematic literature review determining what acoustic parameters are present in classrooms and how they affect both teachers and students. Following the analysis, we put forward a two-block classification: the physical parameters of the sound or noise in the classroom and the consequences of the acoustics on the people in the classroom. Advances in the design of learning spaces and the use of technologies ranging from devices and green material to advanced automation systems make it possible to direct acoustic solutions toward smarter learning spaces. This review also highlights the acoustic parameters to consider in smart classrooms (noise, reverberation, speech transmission and speech clarity) and the main effects of acoustics on teachers and students. Some conclusions and recommendations are drawn, but more research is needed in terms of school improvement considering acoustics influence and smart classrooms possibilities.

Launching a solidarity campaign: Technology-enhanced project-based
language learning to promote entrepreneurial education and social
awareness
- Authors: Melinda Dooly, Dolors Masats, Maria Mont
  Pages: 260 - 269
  Abstract: To promote social consciousness and a sense of responsibility, educational proposals organised around the principles of technology-enhanced project-based language learning (Dooly & Sadler,2016) should engage students in a process of reflecting upon and responding to crucial social issues. Thus, in this paper we will present a project carried out by two groups of primary students who launched a solidarity campaign to collect money for four Syrian children living in a refugee camp in Greece. The project was implemented in a cross-disciplinary Arts and Crafts class taught through English and resulted in significant outputs in English (those addressed to the Syrian children) and in Catalan (those targeted at the local community). First, we outline the student-led project and then we analyse some fragments of student plurilingual practices during the project development that demonstrate their learning gains. Our findings reveal that our meaningful contextualised cross-disciplinary project favoured the natural integration of multiple skills, competences, and field knowledge form various disciplines while promoting a sense of social consciousness and empathy. First, it enabled children to put their plurilingual competence into play and take decisions regarding language choices to meet particular communicative objectives. Second, it contributed to the acquisition of 21st century knowledge, competence, and skills, while helping the learners gain social values. Third, it engaged learners in processes of problem solving, decision making and creative thinking that lead to the development of entrepreneurial competencies. To conclude we argue that when young learners are given responsibilities and opportunities to take up socially relevant challenges learning becomes meaningful for them and those around them.

Web-based ionic liquids learning media to measure the competence of the
Polytechnic student
- Authors: Ina Yulianti, Ida Hamidah, Mumu Komaro, Ahmad Mudzakir, Maizam Alias
  Pages: 284 - 294
  Abstract: The rapid development of technology and information has influenced students' learning styles and has led to a shift in information seeking from paper books to e-books. The purpose of this study is to measure the competence of students on the ionic liquid material, including ionic liquid knowledge, attitude, and skills, as well as website knowledge. The research sample is Chemical Engineering students in a private polytechnic in Indonesia and taken through a purposive sampling technique. This website-based learning is tested on students through the experiential learning model. Data collection was carried out by filling out a Likert scale competency test at the beginning and the end of the study. The results revealed that website-based ionic liquid learning attracted the attention of students, but not all students can do it independently yet. The learning still has to be combined with lecturers' explanations as reinforcing concepts. The implications of this research are expected to be used as recommendations in enriching the Chemical Engineering education curriculum by adding website-based ionic liquid material.

region: A Project-based learning implementation
- Authors: Syahril Syahril, Rahmat Azis Nabawi, Dian Safitri
  Pages: 295 - 314
  Abstract: Developing engineering students whose ability to work and make a real contribution to the development of technology can be done not only after they have graduated from college but also when they are still in college. One of the strategies is by implementing project-based learning with the project based on the potential of the student's region. This study aims to reveal students’ perceptions of learning and soft skills acquisition toward the implementation of the strategy to answer whether the project is effective to implement. This study was conducted on fifty-one Indonesian college students who took Mechanical Drawing course. It belongs to a one-shot case study with mixed-method approach. The result shows that the project based on the potential of the student’s region is effective to raise their perception of motivation, interest, real-world, very beneficial, learning more lecture and enjoyable so that they learn more actively and provide more time to study. It also develops students’ soft skills, including teamwork, project management, communication, and interpersonal skills. The results may have pedagogical implications in improving learning quality in Mechanical Drawing course by enriching project references used in implementing project-based learning. Furthermore, the project given can be a solution in developing the potential of the students’ regions.

Engineering instructor perception of problem- and project- based learning:
Learning, success factors and difficulties
- Authors: Mikel Garmendia, Zaloa Aginako, Xabier Garikano, Eneko Solaberrieta
  Pages: 315 - 330
  Abstract: This work considers three research objectives: to analyze the perception of instructors of the incidence of PBL/PrBL on content learning and skill development; to identify the success factors that they believe promote learning when using them, as well as their importance; and to identify the difficulties they face, and the frequency with which they occur. The responses to a questionnaire administered to 50 instructors who participated in a specific training program were analyzed. The results show that the instructors’ perception is that both models contribute to a better understanding of the contents with regard to their practical application, and to a high level of skill development in their students, with the most favored being group work, decision-making, autonomous learning and problem solving. The instructors consider important success factors to be student involvement in their own learning from the very beginning, feedback from the professor, the tasks having been well-designed and team work and cooperation among students. The most common difficulties identified in our study correspond to the excessive workload associated with monitoring the students, and managing and developing within the established time the planning of their tasks and activities, although there is a medium level of incidence in this regard, and it may be due to the characteristics of the training program received. Exploring these aspects in greater depth in future investigations could facilitate the development of more effective teaching practices.

Virtual escape room and STEM content: Effects on the affective domain on
teacher trainess
- Authors: Félix Yllana Prieto, Jin Su Jeong, David González-Gómez
  Pages: 331 - 342
  Abstract: In recent times, there has been growing disinterest by students in STEM disciplines (science, technology, engineering, and mathematics). This trend is especially acute in those students who do not take STEM content during their secondary or high school education. This disinterest might be conditioned by negative emotions towards science developed by students during the different educational stages, even from an early age. In this sense, active teaching methodologies, such as gamification, play a fundamental role in fostering positive emotions towards learning STEM content. Within the wide range of gamification methodologies, we find educational Escape Rooms. Due to the current situation generated by COVID-19, many of the lessons have had to be adapted to a virtual format through various online platforms. In this study, in a preliminary manner, we aim to analyze the effects on the affective domain produced by a virtual Escape Room used in a STEM course as an instructional tool to teach contents about the Universe to teachers in training. According to the results obtained, the positive emotions of “happiness”, “satisfaction” and “fun” are significantly increased after the intervention. At the same time, some negative emotions, such as “nervousness”, “frustration” and “worry” also increase, partly due to the components typically found in this type of games. Based on these results, it is concluded that, despite the existence of both positive and negative emotions, the results are promising and the intervention is motivating and stimulating for the students.

Developing computer-assisted formative feedback in the light of resource
theory: A case on heat concept
- Authors: Ahmad Suryadi, Sentot Kusairi
  Pages: 343 - 356
  Abstract: Every student needs feedback to understand a scientific concept deeply. However, with a large number of students in each class, individual feedback is a challenge for teachers in Indonesia. Although there have been many studies conducted to maximize the giving of personal feedback, studies conducted by ensuring the consistency of a student's knowledge of a concept before providing feedback are rarely disclosed. This study aims to develop computer-assisted formative feedback (CAFF) based on students’ cognitive resources. Besides, this study also intends to determine student perceptions related to the use of CAFF. This current study involved two experts as advisers in the development process and 31 high school students who acted as participants in the pilot phase. CAFF could identify the students’ cognitive resources and then provided interactive feedback to students based on it. Therefore, it will be beneficial to associate students’ prior knowledge with scientific concepts. Instead of giving feedback by showing whether or not students' answers are correct, displaying the exact concept text, or providing general instructions to the right concept, CAFF presents feedback by showing students' cognitive resources then followed by the interactive explanation associated with specific cognitive resources. Students shared positive perceptions about the program. Cognitive resource diagnoses and forms of feedback in the CAFF model can be further developed on more nuanced topics.

On assessment and evaluation of teaching computer networks to electrical
engineering students by the aid of a lab course
- Authors: Atef Abdrabou, Walid Shakhatreh
  Pages: 388 - 402
  Abstract: In the era of Internet-of-everything, learning the principles of data communications and networking is inevitable for many electrical engineering disciplines. The paper addresses the effectiveness of teaching the fundamentals of data communications and networking using a dedicated lab course as a co-requisite to a classic lecture-based course. In the introduced lab course, the students are asked to do a variety of tasks using real hardware and a network simulator. The paper introduces quantitative measures of an outcome-based learning approach applied to both courses. Based on students’ achievements, the role of the lab course in the attainment of both the course learning outcomes and the electrical engineering program learning outcomes is measured in comparison with the case where the lab course is not taken. Our findings reveal a general enhancement trend in the attainment of the course and program learning outcomes with a significant increase in the program outcome related to solving engineering problems. Also, a slight increase is noticed in meeting the lab course outcomes for the students who attended the lab with the course in the same semester, which indicates an improvement in gaining practical knowledge.

Prospective primary teachers’ views on the nature of science
- Authors: Rafael Amador-Rodríguez, Agustín Adúriz-Bravo, Jorge Alberto Valencia Cobo, Roberto Reinoso Tapia, Jaime Delgado Iglesias
  Pages: 403 - 418
  Abstract: This article presents the results of a piece of research that analyzed the views on the nature of science (NOS) among student teachers enrolled in programs of Primary Education at two public universities in Spain. Previous studies have reported that science teachers maintain ‘eclectic’ epistemological perspectives on science; in this article, we test if such a hypothesis holds when teachers’ NOS ideas are ‘anchored’ in specific periods and topics of the philosophy of science. We studied 114 prospective teachers attending an undergraduate teaching course with emphasis on the natural sciences at the Universities of Burgos and Valladolid in the period of 2017-18. A Likert-scale questionnaire with 50 items was applied to determine trends in those teachers’ epistemological views on science. The results showed that teachers’ views are mostly correlated with the philosophical period of Logical Positivism/Received View, and to some extent to the period of Recent and Contemporary Accounts. Regarding the classical epistemological topics of correspondence, methodologies, intervention, evolution and representation, teachers’ views could be related to the period of Logical Positivism/Received View and Critical Rationalism, but also to the New Philosophy of Science. The main conclusion of this study is that teachers’ expressed views on NOS are epistemologically eclectic to a much smaller degree when examined with more detail concerning specific periods and topics of the philosophy of science.

The integration of dilemmas stories with STEM-project-based learning:
Analyzing students’ thinking skills using Hess’ cognitive rigor matrix
- Authors: Yuli Rahmawati, Afrizal Afrizal, Devina Dwi Astari, Alin Mardiah, Dyah Budi Utami, Sukro Muhab
  Pages: 419 - 439
  Abstract: This study aimed to analyze students’ thinking skills through integrating dilemmas stories with a Science, Technology, Engineering, and Mathematics (STEM) project in polymers topic. The participants were 47 Grade 12 students from a public senior high school in West Java Province. The research employed a qualitative method to obtain data through classroom observations, reflective journals, interviews, and a concept test. Students’ thinking skills were assessed using Hess’ Cognitive Rigor Matrix, which combines Bloom's taxonomic and Webb's depth of knowledge. The results show that most students reach level C2 of Bloom's taxonomy and level 1 of Webb’s depth of knowledge, meaning that most students understand and recall the information. The results indicate that integrating dilemmas stories with STEM-PjBL enables students to explain using simple sentences and prior knowledge. In addition, this approach provides an opportunity for students to develop their critical thinking, creativity, and argumentation skills through problem-solving and project making.

Perception of the Next Generation Science Standard instructional practices
among Vietnamese pre-service and in-service teachers
- Authors: Nguyen Thi Thuy Hang, Niwat Srisawasdi
  Pages: 440 - 456
  Abstract: STEM education has been emphasized in many countries around the world because of its benefits for students in the new century. In response to STEM education, Next Generation Science Standard (NGSS) has released for a new vision of science education in which learning disciplinary content and crosscutting concepts is through engaging science and engineering practices. Educational reforms lead to a need for science teacher education programs and professional development. To prepare better for pre-service teachers, it is necessary to know their perception about these science and engineering practices. Therefore, this study aims to investigate the perception of pre-service teachers and in-service teachers’ implementation of instructional practices that align with NGSS as well as school principals’ views of science teaching. To get the goal, a convergent parallel mixed-method research design was employed in which quantitative data is a survey of science instructional practices from 187 pre-service teachers and 100 in-service teachers and qualitative data is interviews of 10 school principals in Can Tho city, Vietnam. The finding indicated that pre-service teachers highly evaluated science and engineering practices in teaching science while in-service teachers’ implementation of these practices was lower. In-service teachers tend to use more traditional instruction and incorporate students’ prior knowledge in their teaching. Although school principals revealed their appreciation toward teaching science through practices, they admitted that currently, implementation of these practices has been still limited.

Science and engineering practices in the content of Greek middle school
physics textbooks about forces and motion
- Authors: Margarita Papakonstantinou, Michael Skoumios
  Pages: 457 - 473
  Abstract: It has been argued that students’ understanding of science ideas and concepts is based on their engagement in science and engineering practices. However, research studying science and engineering practices engaging in the content of school science textbooks is particularly limited. The aim of the present study is to develop a framework and investigate (through it) the level at which science and engineering practices engage in the content of Greek middle school Physics textbooks about forces and motion. The analysis was carried out on a total of 61 reports and activities on forces and motion that are included in school textbooks (student’s book and lab workbook) used for teaching Physics to 13-year-old middle school students in Greece. Reports and activities were analyzed using content analysis. An assessment rubric called “Science and Engineering Practices Analytic Rubric” (SEPAR), which evaluates the level at which science and engineering practices engage in the above reports and activities, was used throughout the analysis. The analysis demonstrated the low level at which science and engineering practices engage in the analyzed content of these school textbooks. The SEPAR can be used for analyzing science instructional material. The results mean that no opportunities are provided to the students through the content of these school textbooks so that the students could use science and engineering practices and become familiar with them in order to better understand ideas and concepts about forces and motion.

Incorporating Kahoot! in core engineering courses: Student engagement and
performance
- Authors: Victor Chernov, Sivan Klas, Yael Furman Shaharabani
  Pages: 486 - 497
  Abstract: Technology-enriched lessons can contribute to improving student engagement and learning in engineering courses. In this study we systematically incorporated Kahoot!, a game-based response system, in two mandatory content-intensive undergraduate engineering courses. In both courses, short quizzes were incorporated regularly at the beginning of the lesson. The questions were mostly about concepts, and students earned bonus points. At the end of the course, the students filled in an anonymous survey regarding their perceptions of the Kahoot! part of the lessons. In addition, the students’ grades in the final test were compared to their gains in the Kahoot! quizzes. We found that student satisfaction with the systematic incorporation of the Kahoot! quizzes was high in both courses. Most students were motivated to review the course content before class and about half were motivated to attend class. Most students perceived Kahoot! quizzes as contributing to their understanding of the course content. We also found a positive association between student success in the quizzes and their performance in the final exam in both courses. The frequent Kahoot! quizzes supplied continuous feedback to the students and lecturers, and the students became more engaged in the course content. Our findings indicate that technology-enriched strategies, specifically gamification techniques, contribute to increased student engagement, motivation, and performance in content-intensive engineering courses.

learning quality in pre-service Chemistry teacher
- Authors: Elda Frediana Rety Kartika, Elfi Susanti VH, Nurma Yunita Indriyanti
  Pages: 513 - 525
  Abstract: STEAM learning was design to promote student’s interest in learning chemistry. Integration STEAM into chemistry learning is often seen as a challenge, such as not familiar and lack of knowledge on STEAM in chemistry. Coping, for this reason, a web-based STEAM online platform was designed. This paper reports the use of design-based research (DBR) to develop a web-based STEAM online platform. The paper focuses on two studies that step on the development and validation of the platform. In an attempt to implement theoretically designed learning environments in real-world classrooms, DBR was employed as an overarching framework of inquiry. The two cycles of DBR inquiry provide deep insights into the platform's readability, comprehensibility, and feasibility. The implementation of the framework is specified along with further implications for researchers and practitioners.

The use of physics pocketbook based on augmented reality on planetary
motion to improve students' learning achievement
- Authors: Nadi Suprapto, Handal Setyo Ibisono, Husni Mubarok
  Pages: 526 - 540
  Abstract: This article is one of the results of the augmented reality (AR)-based pocketbook development on the planetary motion which focuses on student learning achievement. The study used the ADDIE model: "Analysis-Design-Development-Implementation-Evaluation". In the Spring Semester 2020, researchers took these steps in producing an AR-based pocketbook on planetary motion materials. The trial carried out on 30 students at a public high school in Surabaya, Indonesia. Evaluation parameters included the quality of AR-based pocketbook, students' learning achievement, and research outputs. The results showed that: (1) the process of developing an AR-based pocketbook on planetary motion fulfilled the product quality criteria: validity, practicality, and effectiveness; (2) students' learning achievement increase as seen from the results of the pretest-posttest scores with the average Gain score was 0.63 in the moderate category; (3) through the development of an AR-based pocketbook, it resulted in some articles in journals and pocketbook media based on Augmented reality. Planetary motion in physics learning is an abstract concept and requires high reasoning. Therefore, the recommendation of this study is the use of AR as a media for learning in other abstract physics concepts.

  Abstract: The problems of learning physics have experienced increasingly complex obstacles amid the demands of online learning due to the COVID-19 pandemic. The purpose of this study is to explain the basic physics learning process through an online system during a pandemic, by evaluating the Self-Regulated Learning (SRL) approach to Problem-solving Skills (PSS). Data were collected through distributing questionnaires, interviews and documentation studies, then analyzed. This study shows that the applied SRL has been implemented well, but has not been optimal in improving PSS in online Basic Physics learning. The unpreparedness of technological devices and the competence of educators and students become obstacles that result in difficulties in solving physics problems so that the expected results are not following the expected learning targets. Also, this study shows the difficulty of learning physics online during the pandemic. Thus, a responsive physics learning model is needed with conditions that allow the delivery of physics material to be well understood, even though it is delivered through digital media. This is a demand that needs the attention of all parties so that the achievement of online learning targets remains optimal and effective in increasing the problem-solving skills of students during the COVID-19 pandemic.

  Pages: 556 - 568
  Abstract: In this research, we show a development process of engagement sub-systems in a blended-learning management system and evaluate the impact of student interaction in the whole system. We develop special sub-systems for engagement purposes via forum, course rating, and class assignment modules. During the system development process, we employ continuous improvement methodology which helps to shorten the software delivery time without disturbing the overall operation. We evaluate the impact of engagement processes in terms of behavioral, emotional and cognitive aspects. Our evaluation results show that by employing the engagement sub-systems we have increased a 0.30 satisfaction point on average (1-5 Likert scale) for 11 evaluation survey questions distributed to 305 students during 2 times evaluation period. Another interesting finding from the surveys is that behavioral (discussion forum and attendance list sub-system) and cognitive (course rating sub-system) aspects have great influences for the students’ activities (class assignment sub-system) which finally has a great impact on their cognitive performances.

  Pages: 569 - 580
  Abstract: Teaching strategies play a vital role in improving learners’ performance. This study investigated the effect of Guided Discovery Instructional Strategy (GDIS) on Grade nine learners’ performance in chemical reactions and determined the effect of GDIS on gender. A quasi-experimental design was used with a sample comprised 75 Grade nine learners purposively selected from two schools in Mankweng Circuit based on Grade 12 poor performances. Learners were randomly assigned to the Experimental Group (EG) (N = 40) and Control Group (CG) (N = 35) taught for two weeks using GDIS for EG, and Talk and Chalk Method (TCM) for CG. The results show that there were statistically significant differences between CG post-test (T-test: t(78) = 19.89; p = 0.05); Cohen d = 4.40 for EG and CG T-test: t(68) = -1.03; p > 0.05; Cohen d = 0.2. EG taught using GDIS outperformed those using TCM (ANCOVA: F = 361.49, p = 0.05). GDIS did not discriminate against gender in EG because no statistically significant differences in performance after the intervention (Mann Whitney U-test: U = 178.50, p = 0.58), suggesting that GDIS improved all learners’ performance in chemistry, but not CTM. The findings provide teachers and stakeholders with empirical evidences on a strategy that improved learners’ performance. Also, GDIS did not discriminate against gender like the TCM, suggesting that the strategy encourages girls to study science, which contributes to narrowing the existing gender gap of male and female in Science, Technology, Engineering and Mathematics (STEM) subjects.

The effect of the use of indigenous knowledge-based Physics comics of
Android-based marbles games on verbal representation and critical thinking
abilities in Physics teaching
- Authors: Almira Eka Damayanti, Heru Kuswanto
  Pages: 581 - 593
  Abstract: This research aims to reveal the effectiveness of the use of an indigenous knowledge-based physics comic of Android-based marbles games on verbal representation and critical thinking abilities. It is a quasi-experiment applying the pretest-posttest control group design. The research sample consists of two classes: the control and experimental classes, each of which consists of 35 students established using the cluster random sampling technique. The effectiveness of the indigenous knowledge-based physics comic of marbles games was analyzed using the quantitative method applying the effect size analysis. The result of the effect size analysis obtained from Cohen’s f in verbal representation ability is 0.11 interpreted as medium effect size and critical thinking ability is 0.43 interpreted as large effect size. This shows that the developed indigenous knowledge-based physics comic of Android-based marbles games in physics teaching gives effects to verbal representation and critical thinking abilities of the students. In other words, the developed comic is effective in improving verbal representation and critical thinking abilities.
