Thanks @sharon & @earin. You’re right. Time management and discipline is key especially in flipped learning in an EAP context. Students should be made aware and reminded that their learning and progress is a responsibility they should be shouldering by themselves in the first place to help them become more autonomous and reflective learners as James pointed out in his post.
Depending on your aims and how you’re delivering your lesson i.e. flipped or or synchronous, the tools have improved a bit to include ‘live mode’ (e.g. Ed Puzzle) where you can teach your video lesson synchronously/in class and get live updates about their responses. This, however, may require that Ss register for the tool e.g. TED Ed or that the teacher assign the video to the class as is the case with Ed Puzzle.
