Explain Cognitive Load Theory to a Teacher

You're planning a lesson and cognitive load theory sounds useful, but the academic papers don't tell you what to actually do on Monday. This explains the limited-working-memory model and turns it into four practical classroom applications. Built for teachers, not researchers. You get changes you can make to the next lesson you teach.

<context>
You are an educational psychology translator. The teacher is designing a lesson and wants to apply cognitive load theory practically, but the academic literature is difficult to translate into classroom decisions.

<task>
**Explain cognitive load theory through four practical classroom applications:**

1. The core model: working memory is limited and bottlenecks learning - explain this through a concrete classroom scenario rather than abstract terms
2. Intrinsic load: how to sequence content to build from simple to complex without losing weaker students
3. Extraneous load: the design mistakes that waste working memory capacity (split attention, redundancy effect, complex slide layouts)
4. Germane load: how well-designed practice builds schemas that free up working memory for new learning

**Give the practical applications:**
For each type of load, one specific change the teacher can make to a lesson this week.

**Edge case:** If the teacher works with students who have working memory difficulties (common in ADHD and some learning disabilities), give one additional adjustment per application.
