Evaluating the effectiveness of flipped learning in an upper-division undergraduate electrical engineering course

This paper explores the implementation and effectiveness of flipped learning methodology, in an upper-division undergraduate electrical engineering course at a public research university. Given the limited research on flipped learning practices in engineering education, this study highlights the potential of flipped learning while addressing its implementation challenges. The objective of this study is to compare the learning outcomes between flipped and traditional classrooms taught between 2006 and 2023, using a quasi-experimental design. Additionally, student perceptions and their performance in various assessments are investigated for the Fall 2023 modified flipped classroom. Students’ feedback garnered at the end of the semester was combined with their grades to evaluate learning outcomes and perceptions of the flipped learning approach. The findings revealed an increase in the grades for the flipped classroom. The Fall 2023 students’ feedback indicated a preference for collaborative and active learning methods while revealing a reluctance to engage with pre-recorded videos, posing a major challenge in implementing flipped learning. The paper offers implications for future flipped courses, including methods to incentivize students to watch the pre-recorded videos and mitigate uneven learning outcomes in collaborative learning environments. Furthermore, it was observed that not all students prefer the flipped learning format. Hence, integrating mini-lectures may cater to students who prefer the traditional approach while maintaining the benefits of flipped learning.

Research on Electrotechnics Teaching Based on BOPPPS Teaching Mode

Electrotechnics has the characteristics of strong abstraction and comprehensiveness. In the current teaching, many teachers have the problems of single teaching method and insufficient design of teaching links, and students' enthusiasm for classroom participation are also weak. This is due to the unclear role of teachers in the teaching process and the lack of timely and effective feedback from students in the learning process. In this paper, BOPPPS teaching mode is applied to the teaching of electrotechnics. It follows the student-centered principle and is designed based on constructivist learning theory. This teaching method is highly implementable and interactive. If teachers apply this new teaching method, they can make the teaching of electrical engineering more diversified, and the number of students' participation becomes more. This paper also combines the electrical engineering course with the BOPPPS teaching mode to analyze the strategy in stages in order to improve the teaching quality of the course.

Design thinking and shared ignorance as a framework for student-faculty partnerships

This case study describes and discusses how student-faculty partnerships can be strengthened through design thinking and the establishment of shared ignorance, i.e., an awareness of how none of the involved parties understands the problem or knows the optimum solution of the partnership project. As a case, we use a student-faculty project that aimed to develop course material for an electrical engineering course based on project work involving wicked problems. This project illustrates, through student and faculty reflections, how design thinking and shared ignorance can be used to subvert implicit power structures and strengthen the partnership and project outcomes.

Relationships of Abstraction and Application Complexity in the Attainment between Mathematics and Electrical Engineering Modules in Diploma Courses of South Africa

In South Africa, universities are under pressure to meet increasing targets for student enrolment in engineering disciplines and fields. This has resulted in many students being enrolled in engineering programs without possessing the minimum required mathematical skills and understanding to tackle the challenging engineering disciplines. Hence, the engineering disciplines have a high student attrition and failure rate. This study aimed to evaluate the complex relationship of abstraction and application between mathematics attainment and principles of electrical engineering attainment by the students enrolled in diploma courses in technical universities of South Africa. A blend of quantitative and qualitative data was used. Legitimation code theory (LCT) was used to determine the complexity of higher learning levels. The relationships between six core courses in the Electrical Engineering curriculum were investigated to analyze the knowledge building from mathematics modules to principles of electrical engineering modules. The problem-solving, analytics, and abstract mathematical skills developed in these modules impact the overall progression into principles of electrical engineering courses at different levels for diverse students. The research examines the theoretical foundation, student performance, and practical application of mathematical ideas in electrical engineering using curriculum documents, student academic records, and interviews with electrical engineering lecturers. The study found a weak correlation between the two modules and examined how resources, cultural attitudes, and pedagogy affect student achievement. The results indicate an unexpected negative and fragile correlation between the lower mathematics and engineering modules at high levels. The LCT analysis showed the disconnect between the mathematics courses and the principles of electrical engineering in both the level of abstraction used in the studies and the extent of application principles taught.

Non-Major Students’ Perception on the Application of Gamification and Simulation in Electrical and Electronics Engineering Courses at Universities in Malaysia

In the field of electrical and electronics (E&E) technology that is evolving rapidly, the Ministry of Higher Education Malaysia emphasizes universities to ensure that the expected non-major E&E engineering graduates are fully equipped with the skills to fulfil market needs. However, it is challenging for non-major students to understand the topics taught to them through the methods as they are conventionally being delivered. Therefore, gamification and simulation such as Kahoot, Quizizz, Multisim and CircuitMod have been applied in the university to facilitate formative assessment in order to enhance interest and understanding, and also accomplish learning more effectively among non-major students. Hence, this research aims to examine the non-major students’ perception of the implementation of gamification and simulation in class for face-to-face and online settings. To achieve this, a set of questionnaires was adapted with some modifications for the purpose of data collection. It was distributed to the students from random public universities in Malaysia who are currently enrolled in E&E engineering courses at their respective universities which majority of them are from a mechanical engineering background. Research questions concentrate on the advantages and students’ perceptions of gamification and simulation in E&E engineering courses. The collected data has been analyzed using descriptive statistical analysis. Based on the perceptions of the participating non-major E&E engineering students, the majority of the respondents agreed that gamification and simulation provide a better learning experience with the highest score mean of 4.22. Moreover, gamification and simulation boost students' ability to learn, motivate them, increase their understanding, promote their well-being, and increase their achievement academically. Students hold a positive perception with 4.20 mean score, stating that it is suitable for application in the learning process as it is easy to use, fun, motivating, and more efficient. The results provided would encourage educators in Malaysian universities to better meet the needs of teaching non-major students with their lessons.
