In 2019 we implemented a one-semester, face-to-face introductory course covering algebra-based mechanics, fluid mechanics, and thermodynamics that combined elements from standards- and competency-based education. A report about this course was published in Ref. 1; see also references therein for background. As a response to student feedback, and with the need to go online for the 2020–2022 versions of the course due to the COVID pandemic, we made several adjustments. The aim of this paper is to reflect on the impact of those changes.

The material was originally divided into six units. Students moved from one unit to the next at their own pace by passing unit tests with a score of 80% or higher. Students earning between 70% and 80% were invited for a meeting (interview), described below, which gave them a chance to pass. Those who did not pass needed to retest on their current unit, after being...
