Survey results

Didn’t like me rushing through occasional slides (and rushing in general)

More animations that trace through what is going on in the code

Liked the website, and accessibility of the slides and code

Release the labs and HWs earlier Review sessions for the exams More interesting/fun programs Want more humor slides Not noticing students raising their hands Textbook page numbers

19

Survey results

Include textbook page numbers Liked all the TA office hours More real life examples Textbook not all that popular List of common errors (explanation of Java error

messages) Liked me asking how people understood the material

But should take note of people who don’t raise their hands Didn’t like the test questions all that well Codelab – most liked them Assuming that you understand things quickly Did not like it when I say, “you’ll see it later”

20

The underside of the survey responses

“Serve alcohol in class (free of charge)” Cough drop comments Should bring my dog to class Should start doing some dancing

Last semester it was an Irish jig Give out Mardi Gras beads Dress like a clown
