On Potential Effects of Digital Teaching on Exam Results?

In this article, a digital teaching format tailored to the teaching in an introductory course in Statistics for Industrial Engineers is compared with the classic face-to-face lecture from previous years. The focus is on the comparison of the examination results of the classic lecture in the four academic years before the COVID-19 pandemic with the results of the online course of the academic year 2020/2021 − with the surprising result for the authors that the examinees performed significantly better under the new conditions than in the past. The discussion of the empirical results includes potential for improvement for future face-to-face, online and hybrid courses.
