This document discusses strategies for developing a three-dimensional curriculum model that is concept-based rather than topic-based. It emphasizes using concepts and generalizations to provide intellectual depth and allow knowledge to transfer between subjects and situations. Specific strategies presented include identifying concepts within subjects, showing how concepts are structured with supporting factual information, and ensuring generalizations meet criteria like containing concepts and present tense verbs. The goal is to develop students' conceptual thinking in order to better meet academic standards and prepare students for the demands of the 21st century.
