Abstract

Practical engineering college teachers encounter considerable difficulty when they teach advanced physical subjects in general, and the principle of operation of the bipolar junction transistor in particular - a subject which forms the basis for electronics engineering studies. The difficulty arises from both the complexity of the device and by the lack of adequate mathematical and physical background among the students. As a possible solution to the above problem we have developed a new learning unit based on computer animation that has been tailored to the practical engineering students’ background. The unit includes basic concepts of semiconductor physics and qualitatively describes the processes occurring in the transistor. Such unit was developed, to the best of our knowledge, for the first time. The current research took place in 2010-2011 and examined the characteristics of the above learning among practical electronics engineering students in a leading Israeli college. The research, which used quantitative instruments alongside qualitative ones, indicates a clear gap between the achievements of students studying the subject of transistor through animation and the achievements of their colleagues who have learned it using static diagrams. The gap, in favor of the former, is expressed by a difference of more than 12 points (out of 100 points) in the total score on average and a difference of almost 14 points in higher-order thinking skills score on average. In addition, students who studied about the transistor through animation express significantly more positive attitudes towards electronics than their peers. They show a greater interest in electronics classes and their sense of competence to successfully deal with problems in the field is higher compared to their colleagues. We recommend including animations, developed with an eye toward the students' background, when teaching the operation principles of electronic devices such as the bipolar junction transistor.
