Abstract
Hybrid and online synchronous delivery of courses is a time-demanding approach to teaching and learning systems that is designed to engage students in investigations of authentic concepts or problems without coming to the pre-assigned classrooms two or three times a week. This study presents perceptions and attitudes of students that attended a hybrid course in environmental engineering that suddenly converted to an online synchronous delivery due to COVID-19. It also presents an assessment of the hybrid and online synchronous delivery approach on the final exam scores as well as the final grades of the same course. The course, ‘Introduction to Environmental Engineering’, was developed as an online course for Civil and Environmental Engineering program students and delivered with hybrid and online synchronous options due to COVID-19 pandemic for several semesters to test the concept. In the hybrid delivery set up, all the quizzes and homework assignments were online while the midterm and final exams were in-class. For spring 2020 the final exam was online and for summer 2020 both the midterm and final exams were online due to COVID-19 adjustment. At the very end of the semesters, an online anonymous survey was conducted with five questions to understand the students’ perception and attitude on exam taking options and learning environment. Students’ perceptions and attitudes about online synchronous delivery approach compared to hybrid delivery approach, as well as the learning outcomes, appeared at face value not to be favorable. However, statistical analysis revealed that differences between online synchronous delivery and the Pre-COVID-19 hybrid delivery were not significant, indicating that, at least for these engineering students, online synchronous delivery is a justifiable option.Keywords
