I think that this model is a great way to teach students material. When a student struggles through academic content, they tend to get left behind. I know from personal experience. When I was a child in school, I really struggled with arithmatic. Math builds upon itself. I was also very shy, so if I didn't understand something, I refused to inform the instructor. This happened in my math classes. Often time, an instructor would complete a chapter, and I still did not understand the content. This only left me further behind when the new chapter began. Using the tools in this model, I would have not moved on to the next chapter until I had a firm understanding of the pre-required material.
