This document discusses principles for effective teaching and learning. It outlines the RIGOR framework which stands for retrieval, interleaving, generation, organization, and reflection. Each component is described in one to two sentences. Retrieval involves regularly testing yourself to reinforce learning. Interleaving means mixing different subject matters to find connections. Generation means explaining concepts in your own words. Organization is creating mental models to structure information. Reflection looks back on what worked and how to improve. The document advocates for making learning an active, effortful process through these techniques.
