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?

The Overlapping Theory
Proposed in his book “Emerging Minds”
Evolutionary development instead of a staircase development
How does change occur?
![Page 11: Robert siegler](https://reader033.vdocuments.net/reader033/viewer/2022061223/54c434de4a7959966f8b45b9/html5/thumbnails/11.jpg)
The Overlapping Theory
Adaptivity to Multiplicity
Variety of Approaches
Discover new Approaches
Effectiveness with Age and Experience
![Page 12: Robert siegler](https://reader033.vdocuments.net/reader033/viewer/2022061223/54c434de4a7959966f8b45b9/html5/thumbnails/12.jpg)
Retrieval Approach
2 + 2 =4Base knowledge, by memory
![Page 13: Robert siegler](https://reader033.vdocuments.net/reader033/viewer/2022061223/54c434de4a7959966f8b45b9/html5/thumbnails/13.jpg)
Alternative Approach
Using Fingers
Counting from the largest number
1,2,3,4,54, and 1 more is 5
![Page 14: Robert siegler](https://reader033.vdocuments.net/reader033/viewer/2022061223/54c434de4a7959966f8b45b9/html5/thumbnails/14.jpg)
How Does Change Occur?With Age and Experience
Choosing Strategies
Frequency of existing strategies
More efficient
Better Selection
