Clements, Douglas H.; Wilson, David C.; Sarama, Julie – Mathematical Thinking and Learning: An International Journal, 2004
The purpose of this research is to chart the mathematical actions-on-objects young children use to compose geometric shapes. The ultimate goal is the creation of a hypothetical learning trajectory based on previous research, as well as instrumentation to assess levels of learning along the developmental progression underlying the trajectory. We…
