I recently read this article about traditional lectures being outdated, that engaging learners in actual activities (i.e. active learning) and flipping your classroom are now imperative despite the challenges.
The author explains why professors might end up being replaced by videos. To some this might sound like a threat but I happen to do this very often when I think my students need more time for practice or discussion. Although you can’t convince everyone that they need to study or do homework before they turn up in class, when they do so, you can see the benefits.
