Day 112: Final Review

We’re down to three class periods before finals (possibly two, if the basketball team makes the state tournament). In both of my courses, we started the final review. While both reviews were pretty similar, it was interesting to contrast how my two classes approached it. In physics, students were quick to grab whiteboards to collaborate on and pull out old quizzes and other work to jog their memory. I also saw a lot of students jumping around in the assignment, looking for the problems and questions they found most challenging to use those as a starting point. In chemistry, we talked about strategies to prioritize what to work on, but most students took a very linear approach and only a few pulled out work from earlier in the term. I saw much more variation in how students approached working together. Two students in particular did a really nice job of bouncing ideas off each other and challenging the other one’s thinking, but other groups “worked together” by agreeing to divide up who would do what portions of the review. No one opted to use a whiteboard for brainstorming and collaborating; when I asked some students about it, they saw it as extra work since they would have to transfer their work onto their paper.IMG_1713

Contrasting these classes really reinforced for me how important it is to work with students in this chemistry course on how to be a student. In physics, I have some of the top students in the school and they come to me expecting that they need to understand the daily work to do well on assessments and knowing that having the right answer down is very different from understanding how to answer the question. Many of my chemistry students don’t see that connection between assessments and what happens day-to-day, so don’t value the daily work as much. I need to keep working on making the value of daily work explicit to my students. There are a few who’ve bought into the idea that what they do today influences how their test will go, and they tell me chemistry is one of their highest grades. My challenge for next tri is to get more students to that point.

 

Day 72: Van de Graaff & Finish Review

Physics: Van de Graaff

We started by discussing the results of yesterday’s lab. It ended up much more teacher-centered than I would have liked; I had a few different concepts I wanted students to take away from the lab, and I wasn’t quite sure how to have students summarize their results on a whiteboard or how to guide the discussion to get students to those concepts. It also didn’t help that about half of my students were on a field trip and the empty room made students more self-conscious about speaking up. After discussing the lab, we played with the Van de Graaff generator. Students did a nice job of using what they’d gotten from the lab to make predictions and construct explanations of what we saw with the generator.

Chemistry: Finish Review

No one managed to finish yesterday’s assignment, so we spent some time discussing together the parts students had finished, then I gave them time to finish the rest. I’d hoped to start a lab today, but many students needed the whole hour to work.

Day 71: Electrostatics Intro & Review

Physics: Electrostatics

This year, I decided to try the electrostatics labs from Eugenia Etkina’s PUM curriculum. The effects were pretty visible and just about every student, including the ones concurrently enrolled in AP Chemistry where they just finished Coulomb’s Law, made some observation they found surprising.

Chemistry: Review

In preparation for tomorrow’s lab, I had students balance the equations for the reactions they’ll be doing, as well as categorize each reaction into the five types that were introduced right before break.

Day 56: Final Review

Final exams start tomorrow, so both classes were reviewing.

Physical Science

Yesterday, students wrote questions for each of the learning targets from this trimester. Last night, I picked some of the questions they’d written to make a Jeopardy-style review game.

Physics

Each group put a problem from the review assignment on a whiteboard and presented it to the class. One of the best discussions happened when a group had a few unintentional mistakes on their whiteboard, which lead to a lot of great conversation about what the answers should be. It was also great to see the progress students have made at communicating what they did by showing their work clearly.

Day 55: Final Review

Final exams start on Wednesday, so both classes did some form of final review.

Physical Science

Students started by doing a short self-assessment on each of the learning targets from this trimester and we talked about how that could help them plan their studying. Next, I had each group come up with at least one possible test question for each learning target. I challenged students to come up with higher-level questions, even when the learning target is a simple one. Since AVID strategies are implemented pretty widely in the building, students were already familiar with Costa’s levels of questioning and provided a decent scaffold for students to make sure they were writing challenging questions. Students submitted their questions to a Google Form, which I’ll use to put together a review game for tomorrow. Having each group do one question per target turned out to be too much, so next year I will ask for one question per unit.

Physics

Students worked on a final review packet that goes back over all of the learning targets from this trimester. Tomorrow, I’ll have students whiteboard their solutions to the final review.

Day 54: Refraction & Final Review

Physical Science: Refraction

Students stuck pens, pennies, and other assorted objects into cups of water to develop some ideas about refraction. Students were very quick to connect their observations in the lab to their experiences from outside the classroom. The couple of students who’ve been bow or spear fishing were especially excited.IMG_1470

Students also made some observations of a laser pointer shining into a tank, aided by some creamer in the water and chalk dust in the air. It made a huge impression on these students when I used the chalk dust and laser pointer to show reflection yesterday, so they were thrilled to see it was still out today.

One particularly observant student noticed they could see three bright dots when the beam hit the side of the thank. We talked a bit about it, even though the students have only pretty rudimentary tools for talking about the behavior of light, and they decided that the center spot was the light reaching the outside edge of the glass while the outer spots was the light hitting the inside edge of the glass. Given the way this course skims the surface of each topic, I was pleased with their conclusion.

Physics: Final Review

Students took their last quiz of the trimester, covering projectiles, then started working on their final review. The review is mostly a packet of their quizzes from this trimester.
