I'm sceptical about the success of this. Math, for example, isn't something you should theach continuously for two weeks (lets say, teaching multiplication) and then go back to two months later (to teach division). It need continuous practice and reinforcement of it's concepts so that, not only you become proeficient with it, but you also understand how and why it works. Ând the concept of 'topics' reminds me of Richard Feynman's Magnets youtube clip.[0] How indepth is the teacher going to go? I remember "learning" photosynthesis three times. The first time, around 4th or 5th grade was just "CO2 comes in, oxygen comes out. That's why plants are important, yadda yadda". The last time, in my 11th grade I was learning about the physical and molecullar processes that happened inside the plant's cells. There is a clear progression in the complexity.
