This paper investigates how the switch to distance learning affected study activity and performance in our online retrieval practice web app used for language learning in Dutch secondary education. We report insights from a data set consisting of over 115 million retrieval practice trials completed by more than 133 thousand students over the course of two consecutive school years. We found that, in this particular learning task, learners’ performance did not slow down and accuracy and response time on open-answer questions increased, perhaps due to students being more focused at home.
