Note Taking and Avoiding Plagiarism

When I take notes I usually find writing things in outline format helps me absorb the information the best. Like:
Main Topic
-Subtopic
        -Notes and points on subtopic
-Subtopic
        -Notes and points on subtopic
etc.
I find that this helps my stay organized and it is pretty easy to do. I know people who also take notes the same way but do it on their laptops which is essentially the the same thing. I usually try and take down most the important information on the teachers slides and some of the important things the teacher says. I know some people don't take notes like myself. Some people print out the teachers slides before class and just take like notes on what the teacher says . I like to write whats on the slide because I think it helps me commit it to memory a little bit easier. Some people don't even take notes they just listen to the teacher and absorb all of the information. I can't do that I don't have a photographic memory and I like to go back and use my notes as a study tool. Ways to avoid plagiarism when taking notes is not to just copy and paste all of the information because when you go back and look at your notes to write your paper your brain will be more likely to copy that information again on to your paper instead of paraphrasing and putting it into your own words. Another way is to properly quote sources and to also cite your sources.
