Do The Prerecorded Lecture Videos Help Students’ Learning During Covid-19 Pandemic? A Case Study
Online synchronous/asynchronous delivery of courses with lecture videos is a time-demanding approach to web-based teaching and learning systems that is designed to engage students in investigations of authentic concepts/problems without coming to the pre-set classrooms two or three times a week. This paper presents perceptions and attitudes of students that have participated in online synchronous/asynchronous and hybrid courses in environmental engineering due to COVID-19 intervention in Spring 2020. Three courses in Environmental Engineering were offered either in online synchronous/asynchronous and hybrid delivery mode with prerecorded lecture videos in Spring and Summer 2021. At the very end of the semesters, an online anonymous survey was conducted with three questions to understand the students’ perceptions and attitudes towards the use of prerecorded lecture videos in their learning environment. The data analysis revealed that overall, 26% of the students did not view the prerecorded lecture videos. Although students’ perceptions and attitudes about the course materials covered and agreements between the course outline and the course content were very in the range of 78-100%, the performance was in the range of 77-80%. However, performance did not perceive any correlation with the students’ perceptions and attitudes.
