NoteTaking - why Cornell Notes?

I love the "BLAugust Challenge!" So I'm going to jump in this month to share a few things I found helpful in the classroom, some favorite sites and tools and such!

Today's blog is inspired by @MarshFosh73's tweet today ... she wrote:
Input needed: How do you give notes in class? Do you give your students typed, fill in the blank type notes? (This is what I do, but am 2nd-guessing.) Do students write notes by hand? Do students take notes on a device? #MTBoS #geomchat

I have created guided notes ... and my colleague next door still does.  But in my last year or two, I tried to go to a more open Cornell Notes style.  Our school emphasized using Cornell Notes across all disciplines.  Some teachers provided the guided notes in that format.  Personally, I like my note-taking to have more flexibility.  So in the first weeks of school I shared various graphics of Cornell Notes, explained why they were important, provided some structured time to set them up, and to complete them.  We even shared a time or two what each of us wrote in our notes ... so that we could get some feedback.

Basically Cornell notes have 3 areas ... cues/questions on the left, notes in the larger right column, and a summary at the bottom.  One routine homework assignment was to create appropriate cue/questions on the left to go with their notes, as well as to summarize the day's work.

I am curious how other folks organize their notes for students in upper levels of math!  How much structure do students need?
