Elaborated Explanations

Elaborated explanations are Self-explanations that make use of multiple sources of information or multiple modes of expression.

For example, an elaborated explanation in geometry requires students to explain their problem solving steps by referring both to verbal information (e.g., naming geometry principles that justify an answer) and visual information (e.g., naming the diagram features that are relevant to chosen geometry principles).
