What is the best way to teach math to high school and college students? Conventional classroom teaching has included explanation of the subject matter accompanied by a limited number of examples, after which students are assigned unsolved problems to work out. Recent research has investigated the effect of increasing the use of “worked out” examples of math problems, and the results have revealed that this teaching method produced more effective results. This manuscript includes a brief review of research findings suggesting that providing students with worked-out examples is more effective than the conventional math instruction method a discussion of the probable reasons for this effect comments on what this body of research suggests for teaching today’s math students, with specific consideration of a recently developed math-learning resource.
