Changing the perception of core competency using student journey – tracking research on the core competencies of EECS students in technological universities

PurposeIn this study a survey with a questionnaire was used to track the learning situation and core competencies of students in electrical engineering and computer science at the University of Science and Technology. A determination of areas that need to be strengthened is used as a reference in the cultivation of core competency in higher education.Design/methodology/approachA total of 320 junior students in electrical engineering and computer science were surveyed and given questionnaires. A total of 219 valid questionnaires were collected for a paired sample t-test, to find and compare changes in core competencies of the group over a period of three years.FindingsHigher education institutions are presently more inclined to competency-oriented education, training and learning. This establishes good relevant practices, enhances core competencies in students and improves their chances of satisfactory future employment. In this study it was found that the general core competencies of students were better than their professional core competencies, and the self-reported core competencies of freshman students were better than those of the junior students. The results showed that core competencies did not grow with the years. This result is most likely due to a gain of knowledge which makes them more able to understand their own shortcomings.Originality/valueMost studies investigating the core competencies of higher education students are cross-sectional studies. This study follows students over a period of three years and provides the results of a longitudinal survey of a group of students' core competencies.

Exploring the Academic Preparation and Performance to the Comprehensive Examination of First-Year Engineering Students

A comprehensive examination is an academic exercise that aims to determine students’performance relevant to their achievements in the previous years of their studies. In the oldcurriculum of the College of Engineering at Camarines Sur Polytechnic Colleges, Philippines,a comprehensive examination is given to second-year students of all engineering programs.With the change in curriculum due to the K-12 implementation, this comprehensive examinationis being planned to be given to first-year engineering students. This study aims to explorethe influence of students’ academic preparation and academic performance on the comprehensiveexamination of first-year engineering students. The researcher analyzed the datafrom 468 first-year engineering students for the academic year 2018–2019 to determine thedegree of correlation between their academic preparation, academic performance, and comprehensiveexamination. Findings showed that senior high school (SHS) tracks have no relationshipwith the academic performance of civil, electronics, and mechanical engineeringstudents. However, for electrical engineering students, there is a relationship between theSHS tracks and their academic performance. Also, the college entrance test (CET) and academicperformance showed a relationship with the comprehensive examination. Findingsrevealed that higher ratings in the CET and academic performance tend to go with higherratings in the comprehensive examination and vice versa. Thus, a comprehensive examinationis an effective way to determine the extent of achievement of students in engineeringmathematics and sciences. This study did not consider any other factors that may affect theresult of the comprehensive examination.

The Affecting Factors of Students' Attitudes Toward the Use of a Virtual Laboratory: A Study in Industrial Electrical Engineering

Virtual laboratory (VL) has become increasingly popular in Post-COVID-19 to support practical learning in the remote learning system. The use of VL was responded to by students with different attitudes. This study discusses the factors that influence the perception of Industrial Electrical Engineering (IEE) students in responding to the use of the VL in the learning process of the Electrical Machines Practicum Course. Based on the technology acceptance model (TAM), students’ attitudes toward using VL (are influenced by perceived ease of use (PEU) and perceived usefulness (PU). At the same time, PU also acts as an intervening variable. The research involved IEE students of the Electrical Engineering Department, at Universitas Negeri Padang. Data collection was carried out by survey using a questionnaire. Quantitative data were analyzed using variant-based structural equation modelling (SEM), with partial least square (PLS) or PLS-SEM. The results showed a significant positive effect between PEU and PU from the VL used against A. PU’s role as an intervener was also positive in mediating the effect of PEU on A so it became more prominent. Thus, it can be concluded that PEU and PU are the factors that must be considered in choosing VL to be applied to a practical learning process in the remote learning system.

Comparative Analysis of Student Performance in Flipped and Traditional Classroom Models

Rapid change in technology has transformed the way of interaction between the teacher and student especially in engineering education where large classes are now common. Students have changed how they want to learn and how quickly they want feedback in their learning. Flipped classroom model has become very important as it promotes active involvement and participation by students and allows the teacher to efficiently engage with students in their learning process. This research study investigates the impact of flipped and traditional classroom models on student performance among third year electrical engineering students. The sample sizes that were considered are 71 and 44 students for year 2019 and 2022 respectively. In the flipped classroom model students were instructed to watch pre-recorded videos before the lecture and during lecture time interactive learning was used to discuss the lecture content. The students performance on four tests were compared between the two groups using t-test analysis. The results show that students who experienced flipped classroom model performed better than the students who attended the traditional class-room model. This finding supports that teaching methods that include interactive learning strategies such as a flipped classroom model can be effective ways of disseminating key engineering concepts to university engineering students.

The Flipped Classroom: Enhancing Students’ Learning in Teaching Calculus

Educators have faced difficulties in efficiently teaching within the present regular school system. State, university, and college officials have been pressed to shift from face-to-face classes to teaching methodologies that address the constraints of the traditional method of instruction. Digital natives, also known as modern educators, spend more class time connecting with students and filling learning gaps with technological tools. To assist the development of learning, they began using interactive movies, interactive in-class activities, and video conference technologies. This includes utilizing a Flipped Classroom. This effort determined the effect of employing the flipped classroom technique in teaching Calculus in order to solve the issues experienced in teaching Mathematics during the new normal. The study included 20 first-year Electrical and Mechanical Engineering students who were enrolled in the second semester of the academic year 2019-2020 students whose problem-solving abilities and Calculus ability were assessed using a researcher-created test. A One-Group Pretest-Posttest Experimental Design was used by the researcher. The experimental study used four sessions of video instruction during pandemic season before the online class interactions. The researchers feel that flipped classrooms are appropriate for teaching Calculus since slow learners can watch the video repeatedly until they understand the material. As a result, assignments in the classroom focused on collaborative learning. As seen by the posttest findings, the use of the flipped classroom technique helped students enhance their problem-solving skills and mastery of solving Calculus issues. Thus, the flipped classroom method was found to be helpful in improving students' problem-solving skills and performance in Calculus among Guimaras State College's College of Engineering and Industrial Technology students.

Genre analysis of introduction section in electrical engineering undergraduate laboratory reports

Background: This study examines the genre of Engineering Laboratory Reports (ELR) introduction section written by Electrical Engineering Undergraduates in a higher learning institution. The aims of this study are to identify the rhetorical moves and combinations of move patterns used by engineering students to write introduction section of ELR. Method: A genre analysis was conducted to identify writing patterns and convention practices of engineering undergraduate students thus a corpus of N= 35 was selected from electrical engineering students in their final year of study. This study adopted Genre Theory as its theoretical framework, [1] analytical framework and [2] BCU approach for analysis procedure. A pilot test was conducted to determine the model that fits the best to describe moves and steps of ELR. The study benchmarks a move or step to be present in at least 60% of the reports. Results and discussion: The finding shows the introduction consists of one main move which is providing background information of the experiment and followed by four subsequent steps which are reference to research purposes, reference to theoretical knowledge in the field, providing an overview of the study and identification of main research apparatus. The move 1 and all four steps identified above are viewed as obligatory, conventional and optional move and steps. The exemplification of finding shows lack of compliance among undergraduates to produce ELR based on university’s guideline in discussing previous literature and underpinning theories, lack of references and citation, absence of description to apparatus used and non-sequential steps. Conclusion: This study posits the importance of collaboration between English for Academic (EAP) practitioners such as English-writing instructors and discipline specific specialist from engineering field to further improve on genre-based writing instruction, and to support student’s understanding in meeting the requirements of university’s scientific technical reports.

SCADA ODL FLIPPED CLASSROOM: A CASE STUDY FOR THE SCHOOL OF ELECTRICAL ENGINEERING

Using open and distance learning (ODL) for courses that included laboratory sessions was challenging to teach and learn during the COVID-19 era. SCADA (Supervisory Control and Data Acquisition), also known as ESE691, is the School of Electrical Engineering elective that requires students to be present in the lab for their mini-project group assignments. During the outbreak, students were not permitted to attend the laboratory, but they were required to complete their assignments. The rapid transition from face-to-face delivery modalities to a flipped classroom will be more difficult for final-year electrical engineering students. As a result, the purpose of this study was to investigate the perceptions of students taking ESE691 in a flipped classroom environment from October 2020 to February 2021. The data was gathered using a qualitative method, and the results were analysed using SPSS. This survey had 68 participants, with 22 female students and 46 male students filling out a google form. The findings show that while using the ODL platform to create a flipped classroom for SCADA, the eight questions are critical. The implementation of the flipped classroom for the internal consistency test has a Cronbach's alpha of 0.819, which is sufficient for the questions' reliability.

Remote Hands-on Experience for Students in Undergraduate Computer and Electrical Engineering

The focus of this research was to analyze current methods for online education for electrical and computer engineering undergraduate programs. From this research, an online model for virtual labs in undergraduate engineering is introduced. Experiential learning was exhibited by students through the hands-on experience with lab equipment combined with user feedback. Software used in this research to simulate traditional lab equipment affords institutions the opportunity to provide instructive methods to remote students who are unable to complete on-campus curricula. The devices used to remotely complete the virtual labs facilitated high-value lab practices and skills comparable to those presented in an on-campus lab. As examined during this research, the opportunity to operate virtual devices with the simulation software delivered an extensive laboratory experience with the capability to create a teaching method for engineering concepts. Data from the students' feedback on the simulated, interactive learning is presented in this paper.

Implementation of Work-Based Learning Among Electrical Engineering Diploma Students in an Electric Utility Company

Engineering students graduating from a higher education institution (HEI) are expected to have hands-on experience to be relevance in employment. Work-Based Learning (WBL) is defined as a learning method that engages or includes students in real-world employment so that they may learn the needs of job competencies, experience the job culture first-hand, and uncover career options. Industrial training (IT) is a work-based learning approach required of engineering students as part of their diploma courses. Implementation of IT with duration of 18 weeks was employed for 27 students Diploma in Electrical Engineering students. Students undergo fields rotation with different appointed supervisors throughout the IT period. The IT that was implemented enabled students to obtain important industrial exposure. Industrial visitation at a coal power plant was arranged to give additional industrial exposure to the students. Oral presentation at the end of the course, logbook and final report submission are assessed by assigned supervisors and lecturers for evaluation of each student. The study has offered insights into current IT implementation as well as some suggestions for the future implementation. To track the institution's IT implementation, the study should be applied to the following cohorts.

Design and Implementation of Real-time Fault Location Experimental System for Teaching and Training University Students

The fault location problem is one of the most important issues in power system operation and control. To obtain an experimental system for teaching and training electrical engineering students, this paper performed a study to design and implement a real-time fault location laboratory-scale model from practical hardware components. The impedance-based fault location method is embedded in the system to determine the distance to fault in the transmission line. Furthermore, the monitoring and controlling program is designed by the Matlab App Designer – A new professional app to create the graphical user interface and use the integrated editor quickly. Several fault types including three-phase fault, phase-to-phase fault, phase-to-ground fault are created to evaluate the performance of the fault location experimental system. The real-time measurement results which are acquired and observed on the user guide interface of the program confirm the effectiveness of the experimental system; therefore, the system can be considered a powerful tool for electrical engineering students.

Teaching color science to EECS students using interactive tutorials: Tools and lessons

Teaching color science to Electrical Engineering and Computer Science (EECS) students is critical to preparing them for advanced topics such as graphics, visualization, imaging, Augmented/Virtual Reality. Color historically receive little attention in EECS curriculum; students find it difficult to grasp basic concepts. This is because today's pedagogical approaches are non-intuitive and lack rigor for teaching color science. We develop a set of interactive tutorials that teach color science to EECS students. Each tutorial is backed up by a mathematically rigorous narrative, but is presented in a form that invites students to participate in developing each concept on their own through visualization tools. This paper describes the tutorial series we developed and discusses the design decisions we made.

The Place of the Natural Environment in Activities for Social Responsibility in the Opinion of Students of Electrical Engineering

The concept of corporate social responsibility (CSR) permeates the curricula of various fields of study at many universities. The aim of the article is to present the assessment of the students at the Lublin University of Technology in the field of Electrical Engineering on the importance of individual dimensions of CSR, with particular emphasis on the environmental dimension. The method used in the study is a diagnostic survey conducted among students of full-time first- and second-cycle studies. The research was carried out using a questionnaire based on the four-dimensional model of CSR developed by Carroll and was extended to the environmental dimension. The tool consists of 60 statements divided into 12 groups. Each group contains five statements—one for each of the distinguished CSR components. The hierarchy of CSR dimensions in both surveyed groups is analogous (economic, legal, ethical, philanthropic, and environmental dimensions). The study groups differed, however, in their assessment of the importance of the legal and ethical dimensions. Bilateral comparisons of individual dimensions in the group of second-cycle students revealed fewer differences than in the group of first-cycle students, which proves that the links between different categories of the company’s stakeholders and obligations toward them are more clearly perceived by the group of second-cycle students. The conclusions from the research make it possible to recommend universities to include in their curricula content aimed at better preparing graduates to undertake CSR activities.
