In my opinion, writing skills require the most processing on behalf of the learners. How to structure an essay in a completely different way from what they are used to now is going to take a few weeks for them. Writing introductions, thesis statements, and being vocal about their arguments is a new skill set for them to master.
Students need to be able to apply the new knowledge directly into practice. Reflecting via Padlet for example or interacting with new information via games, such as Wordwall could also be helpful.
