Coming up with an activity to replace a quiz
How about a “reverse quiz”?

Say to the students that they each have to write 5 questions spread through the material. They provide the q and a and submit them 2/3 the way through the class.

The last 1/3 of the class you diplay the questions and discuss phrasing, ambiguity etc If the class is large then you pick at random, but I always did this anonymously - the number of students who would shout out “that’s mine” was high :) they liked this activity...

I did this with a simple grading structure : 80% for submission of 5 q and 90 or 100% for 5 perfect q ie no errors: grammar, spelling etc You can carve the marking scheme as you wish...

I found they spent more time working with the material for this than they would do for a standard quiz. It was also good as part of revision work.
