Two approaches to the process of guided discovery learning are compared for their impacts on concept understanding. One, referred to as design, emphasizes invention and draws on the simulation literature. The other, referred to as case analysis, focuses on discovery and draws on the case-based reasoning literature. Following a lecture on four…

This article is a rejoinder to TM 501 928. (DEP)

Remarks are focused on two of the findings of a study carried out by Bingham-Newman and Hooper in "Classification and Seriation Instruction and Logical Task Performance in Preschool."

Compared effect of six instructional strategies (discovery, two expository lessons, prototype development, interrogatory, and combination of interrogatory/prototype development) on concept learning of college students (N=230). Results suggest use of prototype developmental method alone or in combination with interrogatory method if high levels of…

Open-ended learning environments (OELEs) provide contexts to support exploration, experimentation, and problem-solving. This paper creates a context for understanding the issues and challenges associated with the design and development of OELEs. Discussion first centers on characteristics of OELEs which differ from traditional learning…
