Case Study of Student Grade Distribution Shifts In Online Engineering Fundamental Courses.

During the pandemic quarantine that started in spring 2020, most of the college courses moved to fully online, including that fundamental engineering course. The present paper investigated the student grade distribution shifts during the online teaching period compared with the regular in-person teaching in a mechanical engineering fundamental course, sophomore-level statics, and dynamics with the data from 318 students in 5 comparable semesters. The top quartile students shifted to a higher distribution by leveraging the technological advantages during online teaching and learning, while the middle quartile students and bottom quartile students still struggled. The findings are inspiring to the curriculum design and development in the future teaching-learning environment.
