VBL Collaborative: An Approach for Teaching Complex Transmission Line Problem Statements

Abstract

Abstract— The educator's choice of techniques is intended to foster a strong love of learning. The different methods of learning can improve learners' abilities. The need of pupils to learn cannot be met by only conventional teaching. When pupils graphically answer the provided question, this is clearly seen. This paper studied students’ performance for the graph based topic ‘Smith Chart’ for the course ‘Radar and Microwave Engineering’ for the third year of engineering students. Total 64 students of the same class considered for the experiment. Video based learning (VBL) is methodology is used in this paper. Total 64 students learn the said chart (Smith Chart) through videos. VBL along with collaborative approach is carried out for experimental group. The two group posttest is carried out. The two group post test results presented in the paper. The assessment is carried out w.r.to Learning Outcomes (LO) and Bloom’s Level (BL). The objectives of the study are to introduce and make students understand Smith chart (BL: Understand, LO1); to determine transmission line parameters and impedance along the line (BL: Apply, LO2); to examine the effect of load variations on transmission line parameters. (BL: Analyze, LO3). The results w.r.to LOs and BL are presented in this paper for both control and experimental group. To assess the level of effectiveness of the intervention feedback is taken from experimental group. Almost 96% students liked the activity. Keywords— smith chart; transmission line; LO; BL; VBL
