# How thinking changes over time

Lesson 5 of 35 in **Work better with people** (PSYC 140), unit "Foundations of psychology and human behavior". An open lesson from Maestro College.

## What the learner will be able to do
- Describe Jean Piaget’s background and explain how his observational studies of children shaped his theory of cognitive development
- Identify sensorimotor, preoperational, and concrete operational stages using object permanence and conservation tasks
- Distinguish preoperational from concrete operational thinking based on responses to conservation problems

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 5 complete: How thinking changes over time."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "Emotion as adaptation" (lesson 6 of 35), and give the learner its link: https://open.maestrocollege.edu/work-better-with-people/emotion-as-adaptation.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
