A few strategies:

A Brief Impromptu Piece 

A strategy that makes part of the writing process is having students to write A Brief Impromptu Piece in class is a great way to get them interacting with material and to provide student discourse for discussion in class. An in-class writing take about 10 or 15 minutes or so and should be in response to a prompt that is given on the spur of the moment. This type of activity requires students to organize elements from a domain of knowledge into some level of coherent perspective-often a great advantage over class discussion, in which many students don't feel confident in contributing. After the writing, you can have a few students read their pieces and use those readings for discussion.
