In one class I teach, students are required to stop periodically and write in their learning logs a summary of what they have just learned. I supply the topic or learning term and they supply the summary. Sometimes I provide a summary, sometimes the class provides a summary but, usually the students write their own summary of the learning. Such learning log entries can make great wiki entries so you can assign one or two two student to post the learning from the class. Students who are absent can quickly find out the important learning from the lesson (what was really important in that chapter?) and students can review the class learning before doing homework based on the class learning. Such posting help in the class review of what we learned last class which starts each new class. Such posting serve as a history of the learnings in the class over the semester or year.
Posting learning logs creates a powerful learning wiki. So how do you use a wiki to improve student learning?
