It seems like our math "Home Links" definitely employ the spaced repetition mentioned here. They are exposed to the same concepts repeatedly over a long period of time. However, interleaving is not incorporated in the Home Links, as the types of problems our students are asked to complete are all the same in each section.
I would love to learn more about "Mind, Brain and Education" methods. I think this could really help up, as we make curricular and instructional decisions in the coming years.
