But if concentration is your aim, it is difficult to pay close attention to a speaker and make comprehensive notes. While you are scribbling away you miss some of what is said. Taking notes from reading is extremely time-consuming unless you limit yourself to the main points. If notes for revision are your aim, you may think you will revise your notes later, but when it comes to the crunch the notes may not seem very meaningful and the exercise may prove to be so boring that you give up. Thinking about your note making There is no single 'best' method of making notes.
Every student is an individual, and different approaches suit different people.
However, taking notes is not going to be very productive unless you are thinking about what you are doing. The term 'note-making' is often used to indicate a more positive learning activity than merely receiving information, or taking notes. If you are actively thinking about what you hear or read, you can make notes. You can think critically about what you are hearing or reading, and analyse it, rather than just passively copying. If you have some familiarity with the topic it will be easier to follow the lecture and regognise the important points.
