ÜBER DIESE EPISODE
Before You Teach Anything New, Do This First
Episode 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)

Key Terms
* Prior knowledge: The information, experiences, and mental models a learner already holds before encountering new material
* Schema: A mental framework — a kind of filing system — that organizes related knowledge in long-term memory
* Subsumption theory: David Ausubel’s 1968 theory that meaningful learning occurs when new information is incorporated into existing mental structures, rather than memorized in isolation
* Working memory: The short-term mental “workspace” where active thinking happens; prior knowledge activation helps move relevant information here before the lesson begins
* Anticipation guide: A pre-reading or pre-lesson tool with true/false or agree/disagree statements that prompt students to surface what they already believe about a topic
