The rules I use for representing energy changes.

Leave a comment

Here is what I have been using to teach students how to make pie charts for closed energy systems and LOL diagrams for open systems.

I have started to use the Phet energy skate park simulation to get them to teach me about the rules the pie charts follow . . .  tell me what you think!


What are the rules we learned about energy pie charts


Goal Less Problems

So . . . my wife informed me that it is goal less, not goalless problems . .  glad that is out of the way!

I have stolen them from Kelly O’Shea and have learned quite a bit . . .

First of all, I have decided not to use points . . . instead, I give a rubric grade on the three guiding questions at the top:

1. What is being modeled and how do you know?

2. Diagram / graph the scenario.

3. Find as many interesting quantities as you can from your graphs.

Students can get a 3/4 (on the 43210 rubric scale) on the first question, and then a 4 on the next two statements.

In order to have what I feel is a fair grading system, I give the students a formative assessment goal less problem, then we go over it the next day.   Students tell me what they figured out, and when we are all done, I ask them to tell me what parts show advanced performance, then expected performance, then what would show incomplete performance, then minimal performance.

The students do a pretty good job of knowing what is advanced, and what should be expected.

I have also learned that if you expect students to do pie / LOL graphs, you better give them a picture for each graph!

First Things First . . . .

So . . . I finally created a wordpress blog . . . . I wonder if this will count for my blog posts at Mizzou?

I have learned a lot from wordpress blogs and want to share the love . . .  so here I go!
I have a lot to learn about how to make a good blog site, and my first attempts will be pathetic, but I’ll try it anyway . . .  I am not afraid of looking dumb, it’s second nature to me!
