Virtual Flipped Class and Laboratories for Medical Electronics Course

This paper describes the adaptation of a flipped Biomedical Electronics course with laboratories to remote learning at the start of the Covid-19 pandemic. In class collaborative work on problem sets was replaced by group work (4-5 students) in Zoom breakout sessions. When the groups assembled at random for each class had sufficiently progressed on a problem, a detailed solution was typed on the Multisim circuit simulator desktop (National Instruments) shared on the instructor screen. A laboratory project dealing with the development of an electromyograph (EMG) was redesigned for in-depth exploration of each circuit block composing the EMG circuit that was only feasible with the circuit simulator. The students progressed through the remote section of the course at the same rate as they had in the physical classroom in prior years. Student pairs finished a more complete virtual EMG laboratory project without being hampered by manipulation errors that are typical of novices when assembling hardware circuits. We conclude that a flipped biomedical electronics course can successfully be offered remotely and that virtual electronics laboratories that make use of a circuit simulator can provide a complete and meaningful learning experience.
