I am ALWAYS up for suggestions for how to improve my teaching style or the class itself!!! If you don't feel comfortable telling me to my face (and trust me, I would NEVER have told a TA how to do something!!!) you can email me, leave me a note in my lab, or just put one on the front desk during lab. You don't have to sign them or anything if you don't want to, but I would like any advice on how to make the lab better. Otherwise, I don't hear your suggestions until the next semester...and then it's too late for your class to benefit from them! You can even write them on a sheet of paper and turn them in mixed in with the quizzes or exams.
