A Study of Students Perspectives on Different Pedagogical Practices for Remote Digital Signal Processing Courses

In this Research-to-Practice full paper, we study the perspectives of students on different pedagogical practices in signal processing classes during the pandemic. With the COVID-19 outbreak, universities transitioned to remote operation. While they were not trained for online teaching, instructors had different preferences and motivations of their teaching pedagogy and how to conduct their remote classes. However, only few instructors designed their approach based on their student perspectives. In this study, we survey the students, in signal processing classes, to investigate the different factors that affected their learning under different pedagogical approaches as well as their perspective on active learning and class flipping. Active learning helps maintaining the student motivation while studying from home. Traditional lecturing is the closest to what students are used to. On the other hand, flipped classroom, albeit requiring finishing pre-class activities, enables the students to come prepared and be able to engage more in class activities.
