Reflection: Adjustments to Practice Applying Pythagoras' Theorem with 7 "Choice" Problems - Section 3: Closure: "I used to think....but now I think....


This strategy is good for helping students identify new learning. They examine and explain how their thinking has changed after a reasonable amount of instruction, so it´s pretty much a reflection strategy. I used it for this lesson but it can also be used after a video or class discussion, or at the end of a unit. I addressed the whole group and student´s comments actually helped me assess myself with respect to whether my objectives were met or not. I realized for example, that not one of my more advanced students knew that the Pythagorean theorem could be demonstrated with areas other than squares constructed on the sides. But I also realized that many students learned that the theorem only worked for right triangles, after the Pythagorean converse lesson. So even though I aimed to get information from this particular lesson, students responded with learning from previous lessons. I then asked myself why I didn´t get that message across in the beginning lessons.
