When I go to lectures, I print out the powerpoint and write notes. I don't type verbatim. All you can hear at lectures these days are people madly typing. That may be their way to learn, but not mine.
I write extra things that the teacher is saying, examples they give. I've seen people typing exactly what they already have on the powerpoint, and they miss the actual teachings the lecturer is trying to give.
After I write my notes (either on my pad or the printed powerpoint), I then write the information into my book.
I find when I am writing only a small amount at lectures, I'm focusing on the lectures words, examples and hints they give.
Then I learn again when I re-write the information into my books in order of the powerpoint.
As you write you remember, you focus on the words you're writing, you also think in your own words.
Writing helps you remember. There is a lot of research around this, and I know it works for me!
How do you take notes? Manually or electronically?
