From Online to Hybrid: The Evolution of Flipped Learning in a First-Year Engineering Mechanics Course

ABSTRACT

This paper examines the evolution of a first-year engineering mechanics course, Solid Mechanics I, over the two iterations that it has been flipped. It discusses the teaching strategies that have and haven't worked when delivering the course in both an online and hybrid approach. These include recommended durations for lecture videos, types of assessments, grade distributions, etc. Flipping the classroom was a result of the forced transition online due to Covid-19. To best support the students in the unprecedented times, the instructor opted to combine components from both asynchronous and synchronous teaching styles. Asynchronous lecture videos were accompanied by synchronous class time where the instructor clarified concepts, demonstrated real-life applications, solved higher-level problems, and implemented group activities. A combination of these active learning strategies was the key to structuring the course to keep the students engaged despite being online for all, or part, of the term as delivered in Fall 2020 and Fall 2021, respectively. In the Fall 2020 iteration, the course was delivered fully online to roughly 325 students in civil, environmental, geological, and architectural engineering. Since then, the course had been improved and adjusted in response to the students' feedback collected from an end-of-term survey. Approximately 270 students were enrolled in the course in the subsequent Fall 2021 term which took a hybrid approach as Covid-19 restrictions began to lighten. With students being able to learn in-person again, the course had shifted to emphasize student-to-student and student-to-instructor interactions. Feedback became immediate, allowing for the course to be molded to the students' satisfaction as the term progressed. Changes between the two years have been documented in the paper along with recommendations for future adaptations. © American Society for Engineering Education, 2022
