At a recent conference on departmental support of evidence-based teaching practices in Biology (PULSE), I picked up two Metacognition techniques to bring into my classrooms. These seemed so powerful and, honestly, easy to implement, that I did it the following week.
This first idea stems from work that Ricky Dooley (new colleague in Biology) developed with Scott Freeman and others at the University of Washington. In my majors’ Biology class, I have weekly quizzes over the past week’s material. Standard in-class quizzes, mostly multiple choice (taken with iClickers) with a short answer question here and there. Student performance was mixed, and when we went over the correct answers, many students had “ah-ha” moments when ideas began to click.
Of course, these ah-ha moments were a few moments too late to help on that particular quiz. What I’ve begun doing is flipping that around. First off, I’ve moved this quiz completely onto Canvas. And rather than the usual 10 questions/10 points, they are now 20 questions, still worth 10 points. The first question is the usual question I would ask (although I’ve added more short-answer questions, reflecting questions I will ask on the exams.). This first question (and all of the odd-numbered questions) are worth zero points, so there’s no risk to the student to do their best from their memory (no reason to cheat). The second question (all of the even-numbered questions) is the same question, followed by how I would answer the question. This question then asks the student if they think they got it right, wrong, or somewhere in between. If they didn’t get it right, I ask them 1) explain why they got it wrong, 2) what the right answer is, and 3) why is the right answer correct. This question is worth 1 point, and I grade it based upon how they’ve reflected on their work. Sometimes, within their summary explanations, students will still not fully understand the material. Here, it’s very easy for me to jump in (while grading) and help them individually. An additional benefit is that these quizzes, with the addition of more short-answer questions, more closely resembles the question types I have on my midterms.
The first time I did this (in the 5th week of this quarter), my last question asked the students their opinion on this new style of testing. With the exception of the one student who was already doing exceptionally well, feedback was very positive. They appreciated the ability to correct themselves, and feel that they better understand the material. Their explanations seemed genuine to me, so I’m hopeful that they’ll perform better on our midterms.
The second idea I implemented I borrowed from another biology colleague, Hillary Kemp. This I’ve done with my non-majors Cellular Biology course, one that is typically tough for many students, as they begin their path towards an allied health degree. Exam performance on my short-answer questions is always spotty (lots of higher-order Bloom’s Taxonomy questions). Usually I would go over the correct answer with the class, in the hopes that they’d do better on the final. Now, rather than go over those answers, I give them their marked-up short-answer sections back, and let them correct their answers for partial credit. I stress that in their corrections I’m looking for them to explain why they got it wrong, and why the correct answer is correct. This is worth just enough to eliminate the need to curve the exam (essentially, they’re working to “earn” the curved points). In my large class (n=48), results were mixed. Many students clearly explained why they got it wrong and understand why the correct answer is correct. However, others just put down correct answers or, worse, Googled the answer and put down technically correct answers, well above the level of our course. Again, I awarded points based upon their explanations rather than the correctness of their answers. I think this exam reflection is helping those students who genuinely want to do well in class, as opposed to those who are maybe not too sure about this degree path. I’m hopeful that performance on our comprehensive final will show improvement because of this reflection exercise.
