Teachers discussing pedagogical strategies to help students with an incorrect idea about potential energy expressed competing goals for guiding student thinking: keep it simple and explore complexity. On the one hand, teachers wished to avoid being "overly complicated" in their teaching, suggesting that they should have students stick to naming forms of energy in a system and naming principles like the law of conservation of energy. On the other hand, teachers recognized that students might also engage with, won-der about, and have good ideas about systems, mechanisms, and causality. In addition, teachers themselves showed a need develop operational understandings of energy transformation, conservation, and system even in a simple energy scenario, rather than simply identifying forms and principles. Thus, the initial de-sire for keeping instruction simple was contradicted both by the recognition that students were capable of more complex analysis, even if it interfered with the goals of simple instruction, and by an awareness that understanding even a simple energy scenario involves grappling with complex ideas.
