I don’t do lab reports. Maybe that’s a strange way to begin, here, but stick with me. I haven’t found lab reports to be useful assessment tools in the past. Instead, I have claimed that our work in the lab is too important to grade. It’s the basis of all of our knowledge. On the one… Read More Assessing Scientific Abilities
My Physics 10 (a trimester-long class exploring E&M topics for 10th graders who haven’t yet studied mechanics) was wrapping up some extensions to an electrophorus activity. They were already pros at explaining and predicting electrostatic phenomena, but this activity gave them yet another way to test out their thinking, practice their charge diagrams, and add depth and subtlety… Read More What if we didn’t finish all of the questions?
So you’re thinking in terms of physical models now instead of in terms of chapters, units, or equations. Now what? Is there a high-level ordering of these ideas? How are they connected? Are there common themes? One activity that I’ve done to help students build higher-level organization into their thinking is concept maps (which I… Read More Mechanics: 3 Fundamental Principles
Found in the physics classroom this spring: one standards-based grading focused cootie catcher (aka fortune teller, aka a lot of other names, I’m sure—check out the Wikipedia article about these things if you haven’t seen them before). The outside choices: Meet with Ms. O’Shea, Do nothing, Study, Retest on Sunday. The middle layer was blank… Read More SBG Cootie Catcher
What is LinReg and how can I get it? Note: This is not meant to be an advertisement. I was in no way solicited by, nor am I affiliated with, the creator of the program. This is a recommendation and love letter about a tool that has made a huge difference in my classes this… Read More LinReg for physics class data graphing
Since seeing Brian’s post about asking students this question, I’ve been thinking about how my students might answer. In one section of Honors Physics, we’re just wrapping up a second look at momentum and energy transfer (mainly using problems that involve a transition between using both in the same analysis). My Honors kids have written… Read More Why do we need both momentum and energy?
The graphical solution bug has really gotten me this year (and in the best possible way). I’ve apparently done such a good job of pushing the graphical solutions that one of my classes stopped me in my tracks while I was showing them how to solve force problems by breaking the forces into components and… Read More Force Vector Addition Diagrams (or, Components No More!)
