Development of the Bipolar Junction Transistor Diagnostic Test (BJTDT) to explore the second-year undergraduate Myanmar electronic and Thai electrical engineering students’ understanding of BJT working principles and applications

ABSTRACT A bipolar junction transistor (BJT) and its operation are fundamental concepts for the understanding of power electronics (industrial electronics), transistor-transistor logic (TTL), electronic switching, and signal amplification in modern electronics. Previous research showed that non-major engineering, computer, electronic, and electrical engineering students could not understand the basic concepts involved in a BJT. This paper describes the development of a two-tier diagnostic test, the test’s administration, limitations, the participants’ detailed context, and findings from a study that explores Myanmar and Thai second-year undergraduate students’ understanding of BJT working principles and applications. The results revealed that many students in both countries had the same alternative conceptions about collector current in each operation mode of the BJT. Some alternative conceptions differ from the previous research, such as a) the collector current does not depend on the base current in cut-off mode, and b) changing the collector current does not depend on the base current in active mode, but it depends on the collector supply voltage. These research findings provide valuable information and instruments for teachers to insight, prevent, and correct the alternative conceptions proposed by students.

The labour markets of the transition countries of Central and Eastern Europe relied on stronger growth of the corporate sector as a mechanism for integrating the growing number of laid-off workers. The Serbian labour market has had a similar experience. Decades after the start of economic reforms, however, the role of entrepreneurship as an integrative employment mechanism has not increased in importance, which is best evidenced by statistical data. This paper focuses on students' intention to start their own business after graduation, and specifically examines the relationship between intention and personal attitudes. The experiment was conducted with two groups of students. The results indicate differences in students' attitudes towards entrepreneurship that deepen according to faculty group, gender, and year of study. From the students' responses, it can be concluded that electrical engineering students, female economics students and students in higher years of study are more inclined towards entrepreneurship. This may have implications for measures to support the development of youth entrepreneurship.

Application of Paired Problem Solving for Effective Identification of Misconceptions

Abstract— In engineering education, most courses have numerical problems and complex concepts that need to be applied. Students sometimes find it difficult to apply the concepts in numerical problems and subsequently end up performing poorly in examinations. Timely feedback on numerical problems solved by the students will address this. A systematic understanding of student misunderstandings and misconceptions is likely to lead to improved effectiveness in learning. TAPPS (Think Aloud Paired Problem Solving) is one of the best practices in engineering education and provides an opportunity for students to solve problems collectively by thinking and sharing their individual thoughts and ideas. When the instructor is involved as a keen observer the student misconceptions can be documented comprehensively enabling the instructor to address the problem in a timely manner. TAPPS also provides ample scope for educators to identify individual thinking processes and understanding patterns and therefore enables them to guide the students towards the correct approach to problem solving. This article describes a case study of an implementation of TAPPS with a dialogue conducted for undergraduate electrical engineering students in the third year. Keywords—TAPPS, Numerical Problem Solving, Heterogeneous groups

Model Regresi Cox Untuk Data Masa Studi (Studi Kasus: Data Masa Studi Mahasiswa Fakultas Teknik Universitas Bangka Belitung)

Student study time is the time needed by students to complete their education, which starts from the time they enter college until they are declared graduated or have completed their study period. In the study period data, survival time observations were only carried out partially or not until the failure event. In other words, termination occurs until the observation deadline. This termination occurred due to several factors that allegedly influenced the student's study period. Using study period data for students of the Faculty of Engineering, University of Bangka Belitung, class of 2015/2016, this study used the Kaplan Meier Estimation to see the survival function of each factor causing the length of study period graphically and the Log Rank Test statistically. Meanwhile, to look at the factors that determine the length of a student's study period, researchers used the Cox Regression and Maximum Likelihood Estimation (MLE) models to find the best model. The results of the data analysis show that there are differences in the survival function in each category for all variables graphically, while the statistical comparison of the results of the estimation of the survival function curve based on gender and organizational status is not significantly different. The results of the analysis also show that the proportional hazard assumption is fulfilled through the cumulative hazard log so that categorical variables can be used in the Cox Regression model. Based on the results of the likelihood estimation, the variables that have a significant effect on the study period of Engineering Faculty students are majors and GPA variables. Furthermore, from the interpretation of the model parameters, it is obtained that the Hazard Ratio (HR) value for the study period of Mechanical, Mining and Electrical Engineering students is faster than that of Civil Engineering students, while students with GPA ≥ 3.00 have a shorter study period than students with GPA < 3.00.
