Retrieval Practice in K-12 Schools

I student teach in fourth and fifth grade, and i've subbed here and there. At the same time, i've made it a focus of my kind of research to be in k 12 schools for 15 years or more than ten years. And so almost of my research has been in kato class rooms, which is a bit unusual. So i feel like i have a really fun experience in perspective of 12.
