Computer-assisted learning of electromagnetics through MATLAB programming of electromagnetic fields in the creativity thread of an integrated approach to electrical engineering education

摘要

This paper discusses an integrated approach to electrical-engineering education that incorporates computer-assisted MATLAB-based instruction and learning into the junior-level electromagnetics course and newly created learning studio modules (LSMs). In this model, creativity class sessions are followed by two comprehensive and rather challenging multi-week homework assignments of MATLAB problems and projects in electromagnetic fields. This is enabled by a unique and extremely comprehensive collection of MATLAB computer exercises and projects, reinforcing all important theoretical concepts, methodologies, and problem-solving techniques in electromagnetic fields and waves, developed by one of the faculty team members. These tutorials, exercises, and codes constitute a modern tool for learning electromagnetics via computer-mediated exploration and inquiry, exploiting the technological and pedagogical power of MATLAB software as a general learning technology. The novel approach introduces students to MATLAB programming of electromagnetic fields, as opposed to just passive demonstrations of MATLAB's tools and capabilities for computation and visualization of fields. MATLAB programming tutorials and assignments are designed to deepen student engagement and accommodate different learning styles so students can learn more effectively. In addition to improving students' understanding and command of MATLAB use and programming within the electromagnetics context and beyond, these exercises increase their motivation to learn and appreciation of the practical relevance of the material, and equip them with the tools and skills to excel in other courses and projects. The results of this project were qualitatively analyzed through feedback surveys given to the students at the end of each MATLAB assignment. The Electromagnetics Concept Inventory was also used.
