From 1999-2003, as I've mentioned elsewhere, I taught at the Beacon School in New York City. For three of the four years I was there, I taught the senior physics class, which was a great experience. I was the only one teaching physics, and it was not a Regents or AP course, so I had a ton of flexibility in designing the curriculum, assessments, labs, and so on. Beacon had a midterm and finals schedule very similar to other schools, in that students took their exams during a specified block of time, sitting at their desks, and working bell-to-bell in most cases. For my AP calculus class that I was teaching, this seemed a quite appropriate model, as I knew I was preparing the students for the AP test in May. For my other math classes, I also (at the time) felt the model was appropriate; students were being given a chance to demonstrate in that block how much information they had retained over the preceding semester.
But in physics, things were different. I never loved the idea of a 2-hour physics midterm or final, with every student having to manipulate the equations in the right way to get a specific answer. Such exams tend to fall to the level of "which equation do I plug stuff into to get the right answer" very quickly, but more importantly, also lead to many of the affective issues Kyle talks about in his post. So I had a strange idea, which amazingly enough I was allowed to do.
Here's what it was: About 3-4 days before the exam, I gave every student in the classroom the 20 or 30 exam questions (depended on which exam it was; 20 for final, 30 for midterm). I told them that they could work on the questions from the moment I gave them out, that they could work with others, and that they could use any resource they wished (including the Internet) to help them. Then, every student was required to schedule themselves for a 10-12 minute time slot, which could happen either during the normal exam time or during "outside" times (during my preps when I wasn't otherwise giving exams, for instance, or before or after school). This would be my time to interview them about how the questions had gone, actually doing the assessment.
When the student walked in for their session, I had a deck consisting of some cards - exactly one more than the number of questions given. The student picked 3 cards from the deck. Each card corresponded to a question they'd been given; the student then had to do the questions right there in front of me. I could help them as needed (the degree of help needed would, of course, affect their grade), or just listen while they explained their answer. The extra card was a "wild card" - if the student picked that one, they could choose which of the questions they wanted to answer.
In the year that I did this, I observed a couple of things:
- Students were much more relaxed about the "exam". They knew precisely what I was expecting them to know, and because of the random nature of the process, couldn't "game" it.
- With 20+ questions, it really became impossible to cheat, in the sense of just memorizing someone else's solutions to the questions. They really had to own the answers for themselves to excel.
- The students could, if time permitted, pick a fourth question to do, especially if they felt they'd not done as well as they'd have liked on one of the three required questions. This gave the kids more of a feeling of control over the process.
If you are interested in seeing a couple of the tests themselves, I have them available via Google Drive here and here. They're not particularly hard sets of questions, but they do a good job of getting the idea across about what topics I was covering during each semester.
In spite of this, I am giving real thought about how to resuscitate this model - somehow - in June. The model I used 10 years ago is very simple, and needs serious updating: a more specific rubric for evaluating the students' performances on the one-on-one, more interesting and authentic questions than I asked back then, and preferably a way to get more one-on-one time with each student (I'm convinced 15 minutes should be a minimum), as starters. But the more I think about it the more convinced I am that the model itself had value. What do you think?
I think it's good... but I think it's not just about questions... it's about tasks. Mix it up. Make some of them questions... but have every student choose one thing they build / make / demonstrate using physics.
ReplyDeleteIt's the language of the physical world. Make the final physical.
Agreed. I think the inclusion of an authentic task in the assessment is critical - and in physics, that can link directly to the build/make model. As you and I have talked about thousands of times, the development of an authentic task in mathematics that can be discussed in a short time frame (15 min., tops) is a toughie. But still worth figuring out.

ReplyDeleteThis went a different direction than I thought it might. Just this afternoon I was in a conversation with one of our Algebra I teachers. He missed school on Friday and was supposed to leave a quiz behind but neglected to do so. When he went to give the quiz today some kids complained mightily that they knew this stuff on Friday but not today. This got a conversation going in the class (and then later with me) about just how fragile this knowledge is with the model we use. My mind is going in a hundred directions about this right now and I know I'll check back in when/if I have some coherent ideas. A first thought is that all minor assessments should be low stakes unannounced ones that can actually monitor, to some degree, developing understanding rather than the result of cramming knowledge in for the short term

ReplyDeleteMore thoughts/questions
I have a student with a broken wrist. He lives in my dorm so I thought it made sense to ask him to visit me to take his quiz orally. He told me what to write and I wrote it. I KNOW I gave away some ideas by my reactions. I am also thinking back to my doctoral days when i met you. It was SO hard to stay on script with the questions I had designed instead of just letting a conversation run its natural course. Looking back on your experience at Beacon - how well do you think that you managed the oral portion? Did you have a script? A rubric? I just know that I have a terrible poker face and worry about handling this situation.
Also - do you (or any readers) have any specific advice/criticism/applause about the idea I raised earlier of having many small stakes unannounced assessments? Would that just create an atmosphere of grade induced anxiety?
I think these are all really good issues to raise. During my "oral exams" I'm quite certain that I gave away some of the correctness or not of their answers by my reactions. I, too, have an awful poker face! I don't know exactly how to deal with this issue, except to say that the structure of the interviews needs to be much more scripted than I had made it. And the importance of developing a rubric for these assessments is critical.
DeleteI was thinking some more about your earlier post as well - I think many repeated small-stakes assessments are a good idea. I give "pop quizzes" once or twice a week, that are very small (<10 min) on topics covered a couple of days previously. Students get into the swing of doing them, and they learn that they cannot "forget" the material the next day. Truthfully, I do it so that they don't have to cram a chapter's worth of material back into their heads right before a test, but I don't know that they see it that way.
All this is dancing around a really important question, though: why are we doing this at all? Is this the only mechanism (small-stakes "pop" quizzes or whatever you want to call them) we have to determine what students are taking away from our classes? If it is, does it indicate we need something better?

ReplyDeleteI may be looking for reasons to chicken out of scheduling orals with all of my students - if that's what it ends up sounding like, please call me on it. I work in a school with a large international population. I wonder whether they might actually be at a bit of a disadvantage if they are asked to explain what they understand rather than to simply write what they understand. I certainly get the impression that the interview sessions you are describing should go beyond simply recitation of equations and be deeper than the student writing in front of you rather than writing at their desks. I also think about the naturally shy students and the pressure that they may feel on having to speak up, When I told my wife about the boy with the broken wrist, she said she would have frozen if she had to dictate to her teacher what to write.
It's amazing that Beacon let you run with this idea. Do you think that there is any chance your current school will? What would the schedule management look like to find 20 - 25 hours of interview time in a week of exams?
I shared this blog entry with three of my classes yesterday. Interesting conversations ensued.
