Why it works
The worked-example effect comes from cognitive load theory: novices learn more from studying worked examples than from unguided problem-solving, because their limited working memory is not spent searching for a method. Fading the guidance as expertise grows transfers the thinking to the student.
The research: Sweller on cognitive load and worked examples.

The core activity: plan a think-aloud
Teachers leave with a scripted think-aloud for a task their students find hard.
- Pick a task or problem students struggle with.
- Break it into the steps an expert actually takes, including the decisions.
- Script the think-aloud, narrating the choices, not just the moves.
- Plan a faded sequence: worked example, then partly worked, then independent.
Narrate the decisions, not just the movesThe value is in the 'why I chose this' and 'here is where I could get stuck,' the thinking students cannot otherwise see.
Facilitator notes
- Resist going too fast or too perfectly. Show a mistake and the recovery.
- Use a worked example before problem-solving to cut cognitive overload.
- Fade the support deliberately so students take over the thinking.
Avoid the expert blind spotExperts skip steps automatically. Plan the think-aloud in advance so the invisible steps actually get said out loud.
Adapt it
- <b>Elementary:</b> model with concrete materials and plain talk.
- <b>Secondary:</b> worked examples first, then faded practice.
- <b>Students who need support:</b> annotated worked examples they keep as a reference.

Modeling & Worked Examples: show the thinking
<b>Make expert thinking visible:</b> think-alouds, worked examples, and faded support.
- The task I will model:
- The hidden steps to narrate:
- One decision I will think aloud:
- My faded sequence (worked, partial, solo):
- Where students keep the example:
Make it stick
Keep models visible after the lesson:
- Leave a worked example or anchor chart up for reference.
- Build a bank of worked examples for the trickiest content.
- Bring one think-aloud that worked to the next PLC.
Common questions
Won't modeling make students dependent?
Not if you fade the support, from worked example to partly worked to independent, so they gradually take over the thinking.
Should I ever model a mistake?
Yes. Showing a wrong turn and the recovery teaches students how to handle getting stuck.
How is a think-aloud different from explaining?
A think-aloud narrates the decisions and the stuck points, the thinking that a normal explanation leaves out.
