Several students who reviewed their academic year recognised the importance of taking good notes. That is, knowing the key points to make and writing notes in a condensed form. This teacher makes an excellent point on the relationship between text messaging and note-taking. Students have to make decisions many times a day and PROCESS the key/main points in their text messages.
I've been pushing the Cornell method of making notes with my students and it is an excellent method for making effective notes which great for revising for exams, etc. I'll post a template for this type of note taking soon.
