What is the most important first step in planning an interdisciplinary instructional unit?

Identifying a central theme for the unit is crucial because it serves as the backbone of an interdisciplinary instructional unit. A central theme provides a cohesive framework that connects various subject areas, allowing for more meaningful integration of content. This thematic focus not only helps educators align different disciplines but also engages students by showing them the relationships between various concepts and how they apply to real-world scenarios.

When a strong central theme is established, it guides the selection of objectives, instructional strategies, and resources. It ensures that all components of the curriculum work together harmoniously and that students can make connections across disciplines. This foundational step enhances overall instructional design and maximizes the relevance of learning experiences.
