"Great idea, but it'll never work for my students." I hear this a lot when I encourage teachers to engage students in productive struggle rather than try to prevent struggle. I thought it wouldn't work for my students either, but they proved me wrong.

Don't just focus on what and how teachers need to change. Explain why they need to change.
Giving answers to students in math class shifts the focus away from getting answers.
