Interactive video lessons for electromagnetic education

With the availability of a large number of software packages for electromagnetic (EM) education through the national Computer Applications in Electromagnetic Education (CAEME) Center [1] and other individual efforts, there have been some concerns regarding the ability to integrate this software effectively in routine classroom teaching. Basically, congested EM curricula do not provide instructors with sufficient time to include software demonstrations and simulations during class periods. It is also not clear whether students will be able, adequately and independently, to understand basic underlying concepts and physical phenomena from visualization of colorful graphics and from the output of performed simulations. To help integrate available EM software in classroom teaching for both instructor use and student independent study, CAEME developed three interactive video lessons for student instruction. Interactive media lessons integrate and allow individuals to interactively manipulate information from multimedia such as video, software, and animated graphics, and also include instructional information such as quizzes and tutorials. In this article, we present the features of three interactive video lessons in EM developed by CAEME. These lessons include tutorials, simulations from CAEME software and videos, and quizzes to evaluate student understanding. The lessons use animated graphics illustrating specific dynamic phenomena and specific measurement procedures. They also keep a record of student quiz scores for instructor use. These, as well as other features of the three developed interactive video lessons, and the software and hardware requirements for developing such lessons, will be described.
