![]() Can all trapezoids be rotated to form one long parallelogram? Or is it just specific to certain types?.I still wonder why they didn’t use the formula for the area of a trapezoid: (½)(base1+base2)(height).Here are some of the questions they wrote: We asked the trial participants for similarities and differences, and for questions that either they had, or that they could imagine another learner having. ![]() Judy Kysh years ago.)īeth (Sample Work) Responding to the Prompt I have done lessons around this since the idea came to me via Dr. (These methods are intentionally set up to provoke comparisons in algebra and geometry. In this trial, we showed students two different methods for solving the area of a trapezoid. Students use the peer feedback to revise or extend their original work. Students give and receive peer feedback on that work.ģ. Our open response project at its heart is:Ģ. What happens when we facilitate peer interactions between learners on Khan Academy? Many modern classroom practices involve facilitated peer interactions: students talking to students in a structured way. ![]() But if student work is not machine gradable, how can the students receive feedback? Open response on the internet means breaking away from machine gradable multiple choice or numerical entry as the sole method and representation of student thinking.
