Before You Teach Anything New, Do This First

Before You Teach Anything New, Do This FirstEpisode Summary Prior knowledge activation is one of the most research-backed teaching strategies available — and one of the easiest to use at home. In this episode, Heidi explains what the strategy is, why neuroscience and cognitive research support it, and gives six specific, age-flexible techniques homeschool parents can use starting today.What You’ll Learn* What prior knowledge activation actually is (and why it’s not just a warm-up)* The cognitive science behind why new learning sticks when connected to existing knowledge* Six practical techniques — from the Brain Dump to the Anticipation Guide — that work across subjects and ages* How to handle topics where your child has little or no background knowledge* The mistake that turns activation into a quiz (and how to avoid it)Research & Resources Mentioned* Hattan, Courtney, Patricia A. Alexander, and Sarah M.
