I think I have very poor studying skills. So I've been wondering lately if maybe how I think about notes is wrong. How often do you review your notes for a topic? It probably varies between subjects, but I bet the answer is that once you take notes once most people never review their notes. This is probably more the case for studying done on your own and outside of a school setting because you don't get tested on those topics as much. I guess thats not as effective, but it probably works for most topics given that we all usually have limited time. And, are the notes concise versions of the information (like pegs in a memory system to find the real information) or copies of the information entirely so you don't need to refer to the original anymore? I wonder if with computers the fact that you don't need to copy information form a book to avoid carrying it thanks to PDFs and Kindles has made natural habits that happened before unnatural. Why copy everything when it's right there? Why not just copy and paste it? "Thats what I would have written, it's so much easier if I just copy and paste it." It's kind of like with programming books, esp the intro ones, which always offer the code but tell the reader to please type out all the code. So maybe when we teach those like myself with poor study skills we should explain: Use pen/paper because you can express more, you will probably not read this later so using pen/paper will help you remember more given that, copying information isn't bad (Even if it's duplicate thanks to computers) because it helps that retention factor with information that prior to it being on computers would have been smart to take notes on.
