Piecewise Videos of Engineering Laboratory Sessions Towards Effective Learning and Fair Assessment

Engineering students are required to have laboratory sessions in Electrical Machines courses to support the theoretical knowledge gained throughout the lectures and to foster their interest in research through experimenting, calculating, comparing the calculated with experimental data, doing analysis, model validating, and coming up with conclusions. Due to COVID-19 precautions, students were not allowed to attend the laboratories in person; and as a result, they were exposed to miss the major practical part of the course. Therefore, a laboratory environment is developed through using recorded laboratory sessions, where several sub-movies were recorded for each experiment corresponding to the complete description of apparatus, setup/procedure, measurements, and troubleshooting. During the assigned hours of laboratories, the instructor watches the experiment sub-videos with the students while answering their raised questions. At the end of each laboratory session, students should answer a quiz after watching an extra film to test their follow-up and understanding. The study in this paper investigates the effectiveness of this method in teaching laboratories from the student and instructor point of view and to what extent this method can drive fair assessments.
