This column provides ideas and techniques to enhance your science teaching. This month's issue discusses using the 5E learning cycle to create coherent storylines. The 5E learning cycle provides an important framework to help teachers organize activities. To realize the full potential of the 5E framework for student learning, lessons must also have a coherent conceptual storyline. "Conceptual storyline" describes the conceptual flow and sequencing of science ideas within a single learning cycle lesson that helps students understand a disciplinary core idea and a scientific phenomenon (Ramsey 1993). An incoherent conceptual storyline can affect the implementation of the 5E learning cycle. Thus, the conceptual storyline should be coherent both in terms of activities and scientific concepts. In this article, the authors elaborate on the idea of structural versus conceptual coherence in 5E lessons and describe insights from their work supporting teachers in crafting coherent conceptual storylines.
