Jean Piaget's Cognitive Theory
Children are not less intelligent than adults; they just think differently. They are "Little Scientists."
1. The Brain's Filing Cabinet (Core Terms)
To understand Piaget, imagine a child's brain is a giant filing cabinet.
Schema
The File Folder. A packet of information in the brain. Example: A child has a "Dog" folder containing rules: 4 legs, tail, barks.
Assimilation
Same Folder. Child sees a new breed of dog (Poodle) and easily fits it into their existing "Dog" folder.
Accommodation
Change/New Folder. Child sees a Cow. Calls it a "Dog". Parent says no. Child must change their brain and make a new "Cow" folder.
2. The 4 Stages (Memory Hack: S-P-C-F)
1. Sensorimotor (0-2 yrs)
🙈Learning through senses (touch, taste) and movement.
The Peek-a-boo Rule: Knowing an object still exists even when hidden under a blanket. (Develops at the end of this stage).
2. Preoperational (2-7 yrs)
🧸Language develops. Pretend play begins. Logical thinking is missing.
"Everyone sees the world exactly how I see it."
"My teddy bear gets sad when I drop it." (Giving life to non-living things).
3. Concrete (7-11 yrs)
🥛Logic begins, but ONLY for physical things they can touch or see.
The Water Glass Rule: Realizing that pouring water from a short, wide glass into a tall, skinny glass does NOT change the amount of water.
4. Formal (11+ yrs)
🧠Teenagers. Can think like adults. Understand abstract concepts.
The "What If" Rule: Can solve algebra problems in their head and argue complex ethical issues (like justice or love) without needing physical toys to prove it.
The Pedagogy "Teacher Rule"
A teacher should: Provide physical objects, blocks, and visual aids when teaching primary school children (Concrete Operational stage). Focus on discovering knowledge, not memorizing it.
A teacher should NEVER: Expect a 6-year-old (Preoperational) to understand complex mental math or look at a situation from someone else's perspective (because they are still egocentric).
