I find that a big part of my classroom time is spent teaching my students how to study and convincing them that they can learn and succeed. So many of them are years out of school, and many did not do well the first time around. To help them learn that they can learn the material, we have weekly exams over one or two chapters at most. This breaks the material into small enough pieces that the students won't get overwhelmed by the amount of material covered. After each exam we review the answers and I counsel the students that struggling most. I praise them when their scores improve, and suggest ways they can improve the quality of their study time. When they realize that they can and do improve as they utilize their time more effectively, they tend to improve markedly. So many people simply don't know that they are capable of learning and succeeding.
