At least once a semester I ask my students to write a journal. My main goal of this assignment is to monitor students’ buy-in into my IBL classroom. How is IBL working for them? What is not working? What could they change to improve their learning? What can I change?
I want my students to learn how to write about their thinking. Therefore, my assignments have to be written in full sentences, explain everything in detail and convey the mathematical concepts. They can also contain the story of how the student discovered the solution, including all struggles and mistakes.
This semester we are video taping our IBL classes and as I am watching the videos I am reflecting (again) on all the pieces necessary for a productive whole class discussion. My goal for a discussion is to make the “Big Mathematical Ideas” visible by having students construct connections between different solution strategies or attempts.
