Try to encourage more participation. Maybe tying recitation to lecture more closely would be helpful. More activities, surveys, etc. Possibly some group activities. I don't have any real suggestions.
Recitation is great as is.
I liked the recitation, but maybe have a little more formal structure for it. Maybe practice quizzes to help us apply concepts. A lot of times what we learn in class sounds easy but it is hard to apply. Weekly or bimonthly practice quizzes would help a lot. Overall I liked the course on the whole.
