Why Children’s Cognitive Learning

Robert Siegler decides on Children Cognitive Learning.

Robert Siegler’s Contributions

• Children’s Cognitive Development Particularly Math and Science

Children’s Understanding of Numerical Line Representations

-Numerical Board Games

Proposed the Overlapping Wave Theory

Number Line Representation

0 100071

Where would the number 71 be positioned in this number line?

Improving Numerical Understanding

Number Board Game

Color Board Game

Effects of Linear Numerical Board Games

Effects of Linear Numerical Board Games

The Overlapping Theory

Proposed in his book “Emerging Minds”

Evolutionary development instead of a staircase development

How does change occur?

The Overlapping Theory

Adaptivity to Multiplicity

Variety of Approaches

Discover new Approaches

Effectiveness with Age and Experience

Retrieval Approach

2 + 2 =4Base knowledge, by memory

Alternative Approach

Using Fingers

Counting from the largest number

1,2,3,4,54, and 1 more is 5

How Does Change Occur?With Age and Experience

Choosing Strategies

Frequency of existing strategies

More efficient

Better Selection

Thank You!
