Student feedback on having weekly practice quizzes (instead of homework)

This term I eliminated the weekly homework assignment from my calc-based intro physics course and replaced it with a weekly practice quiz (not for marks in any way), meant to help them prepare for their weekly quiz. There’s a post coming discussing why I have done this and how it has worked, but a la Brian or Mylene, I think it can be valuable to post this student feedback.

I asked a couple of clicker questions related to how they use the practice quizzes and how relevant they find the practice quiz questions in preparing them for the real quizzes. I also handed out index cards and asked for extra comments.

Aside from changing from homework assignments to practice quizzes, the structure of my intro course remains largely the same. I get them to do pre-class assignments, we spend most of our class time doing clicker questions and whiteboard activities, and there is a weekly two-stage quiz (individual then group). I have added a single problem (well, closer to an exercise) to each weekly quiz, where in the past I would infrequently ask them to work a problem on a quiz.

Clicker Question 1

Clicker Question 2

Just from a quick scan of the individual student responses on this one, I saw that the students with the highest quiz averages (so far) tended to answer A or B, where the students with the lower quiz averages tended to answer B or C. I will look at the correlations more closely at a later date, but I find that this is a really interesting piece of insight.



Additional Written Feedback

Most of the time I ask the students for some feedback after the first month and then continue to ask them about various aspects of the course every couple of weeks. In some courses I don’t do such a great job with the frequency.

Usually, for this first round of feedback, the additional comments are dominated by frustration toward the online homework system (I have used Mastering Physics and smartPhysics), requests/demands for me to do more examples in class, and some comments on there being a disconnect between the weekly homework and the weekly quiz. As you can see below, there is none of that this time. The practice quizzes, the inclusion of a problem on each weekly quiz, and perhaps the provided learning goals, seem to do a pretty good job of communicating my expectations to them (and thus minimize their frustration).

Student comments (that were somewhat on topic)

  • I feel like the practice quizzes would be more helpful if I did them more often. I forget that they have been posted so maybe an extra reminder as class ends would help.
  • The wording is kind of confusing then I over think things. I think it’s just me though. Defining the terms and the equations that go with each question help but the quizzes are still really confusing…
  • Curveball questions are important. Memorize concepts not questions. Changes how students approach studying.
  • The group quizzes are awesome for verbalizing processes to others. I like having the opportunity to have “friendly arguments” about question we disagree on
  • I love the way you teach your class Joss! The preclass assignments are sometimes annoying, but they do motivate me to come to class prepared
  • I enjoy this teaching style. I feel like I am actually learning physics, as opposed to just memorizing how to answer a question (which has been the case in the past).
  • I really enjoy the group quiz section. It gets a debate going and makes us really think about the concepts. Therefore making the material stick a lot better.

Last thought: With this kind of student feedback, I like to figure out a couple of things that I can improve or change and bring them back to the class as things I will work on. It looks like I will need to ask them a weekly feedback question which asks them specifically about areas of potential improvement in the course.

Nonlinear narratives in the inverted classroom

I have temporarily taken over an introductory E&M course from one of my colleagues. I’m teaching the course using his format (and notes) which means that I am (A) lecturing and (B) not using pre-class assignments for the first time since 2006. In addition to his format, I am using the odd clicker question here and there.

The thing that has been the most interesting about lecturing in a non-inverted class has been the difference in narrative. In my regular courses, I assume that the students have had contact with all the major ideas from a given chapter or section before I even ask them the first clicker question. Because of this we are able to bring all the relevant ideas from a chapter to bear on each question if needed. This is what i am used to.

My colleague’s notes develop the ideas in a nice linear fashion and very easy to lecture from, but I just can’t stop myself from bringing in ideas that are multiple sections down the road. I am having a ton of trouble, even with a set of notes in front of me, letting the story develop according to a well laid-out narrative. It has simply been too long since I have presented material in this sort of a structured way. Note that when I give a talk at a conference it takes me a ton of practice to massage the talk I have prepared into something which I am able to deliver using a nice linear narrative. Even when it is nicely laid out, I will jump ahead to other ideas if I don’t spend some serious time practicing not doing that.

It has been really interesting being the one completely responsible for the narrative instead of sharing that responsibility with the resources that I provide for my pre-class assignments.

It has also been weird not having the inmates run the asylum.

This was my last year to teach Gauss’ Law early in the course

The Matter and Interactions textbook has it right by bundling Gauss’ Law and Ampere’s Law together near the end of the E&M section of the book. I don’t think either of these topics belong in the introductory course at all (actually I don’t even think E&M topics belong in first year period). But since my hand is currently forced, Gauss’ Law will be a topic for the last couple of weeks in my future intro E&M courses.
