Can daily quizzes aid student engagement?

Physics

I'm in the middle of an explanation, when Claudia turns to John and says: "..[look, John, I think Marco is trying to say that]...the electric-potential is to the potential-energy what the electric field is to the Coulomb force!...". a spontaneous intervention by then common in my class. There was a strong sense of confidence in her words, in contrast to her personality, which was very quiet, in fact. So, how did we get there?

Hola! I am Marco Bonett-Matiz, a PhD student and YTC fellow. I am passionate about teaching, and last summer was the third time I served as the instructor of an introductory physics class. Below, I want to share the results of my experiment: the evolution of quizzes in the course, and their contribution to the sense of camaraderie and rapport among my students.

It all started when, as an undergrad, daily quizzes had a strong influence on my study habits; based on the previous day's lecture, these quizzes forced us to stay on our toes. Right then and there I decided that I would implement them in my classes.

I co-taught the first version of my Phys 181 course with my best friend here at Yale (also a YTC fellow by the way). During the planning stages, one of my strongest suggestions for the class was to implement daily quizzes. In retrospect, I was not totally aware of their effect; my thinking was: this will keep them on their toes and primed for class. Later I realized the quizzes also made them arrive on time: they started at nine sharp without delay and with no make-ups permitted. Everyone was on their seats by the beginning of the lecture and this reduced interruptions due to late comers.

For the second version of the class, I felt confident and daring: I increased the frequency of clicker questions and allowed for Think-Pair-Share (TPS) activities. However, I did not change the structure of the quizzes. I cannot be sure what triggered it, but there was a time after the end of a quiz when I couldn't start the lecture because of the noise. My students were engaged in discussion about their answers. I was so pleased that, when they finally noticed me, I suggested they finish their deliberations without rush. This was their discussion and I was only an observer. Soon after it hit me: "Next summer I will have them submit their individual answers, followed by peer-discussion and then resubmission".

Full of positive feelings and excitement, I was ready to implement some changes into the structure of the quizzes. The third time I taught the class they consisted of: Three multiple-choice questions, four minutes total for individual submission, followed by three minutes of peer-discussion before resubmission. This strategy wasn't without its problems, and at first the students resented me for not giving them enough time. We struck a deal: they would have more time at the cost of staying five minutes later at the end of class. They accepted without hesitation. This third time however, there was a noticeable change: The students felt safe to intervene and engage with the material. As a class, we had pierced through that ice that sometimes prevents students from actively participating.

Having witnessed their engagement in a relaxed environment that we had built together was among the most rewarding moments with this class.

I don't think the quizzes by themselves were the only reason for their engagement. We also had TPS questions, strong encouragement to participate, and in-class activities. But I would dare to speculate that daily quizzes followed by peer discussion planted the seed that fostered a healthy environment for participation. They created an atmosphere where it is ok to be wrong, it is ok to intervene if you think you have the right answer, and it is ok to engage in cordial discourse. The consequence was enthusiastic participation by most, as they asked questions, answered them, or gave a better version if I, as the instructor, was not able to nail it with my answer.

At first, I naively thought all I wanted was for my students to be ready for my lecture. In the process, I discovered a tool that enabled them to engage with the material and helped create a healthy environment where it was safe to participate.

In case you hadn't noticed, I didn't mention the students' motivator...I had to make the quizzes worth 15% of their grade. Without it, the efficacy of the experiment would have been greatly diminished, I'm sure.

Please feel free to share; I'd love to hear your opinion.

Cheers!
