Looking at how students study, it is obvious that people approach learning in different ways. Some students like to read the textbook once through, some highlight and annotate the textbook extensively, some write and rewrite their notes, others record and play back lectures, others still make and review flashcards, and so on… But what do these differences in study strategies reflect? There are many possibilities. They may reflect variations in the way that people learn, or it may reflect differences in work ethic or learned habits. Researchers have mistakenly interpreted these differences in preference to reflect differences in the way that people learn and learning styles has become a popular and widespread pedagogical approach.
