One method that I use in teaching is anticipation. Some concepts that will be seen further on in the course will be introduced earlier through seperate exercises. Once the concepts have been introduced, when the student reaches the same concept in his/her text, the "ah ha" will come. For example, in teaching a reading course, it is important to know the topic/main idea of a passage. However, sometimes figurative language or inferences may interfere with the earlier comprehension. Before we explore figurative language, I use handouts and/or readings beforehand. When the students reach the particular area in the course, they not only find the concept easier, but really remember afterward.
