Tree of Thought Lesson Optimizer

I need to improve this lesson on {{topic}}. Lets explore multiple approaches:

Branch A: Focus on engagement - How could we make this more interactive?
Branch B: Focus on clarity - How could we explain concepts more clearly?
Branch C: Focus on assessment - How could we better measure understanding?

For each branch, generate 3 specific ideas. Then evaluate which ideas are most promising and could be combined. Finally, synthesize the best elements into an optimized lesson plan.
