How to make my curriculum unit EVEN better!

1. My lesson on the beginning of the war: I got comments that a graphic organizer might help because it's so much info. I kind thought that a K-W-L might work. They could do what they've heard about the Gulf of Tonkin Resolution (a big chunk of the lesson). I also think I probably should've included some type of worksheet or questions to go along with when they were reading it.
2. In this lesson, students are comparing the differences in policies between JFK, LBJ and Nixon. I didn't quite understand what the MIVCA "challenging" meant. What I should have put as "challenging" was the fact that students are getting new information from different medias and sythnesizing them onto charts.
3. I received the comment that I probably didn't plan enough stuff for my lesson on the anti-war protests. I could add an exit slip: You were drafted. Write a letter to your mother/father/girlfriend/etc. I could also make sure I have specific questions for the discussion, including: How many of you would have participated? How many of you know someone that was involved? Would you consider participating in the Iraq war? Are there similarities between the two? Etc.
