Conceptual Development of Preservice Teachers Through Verification Versus Guided-Inquiry Physical Science Laboratories

• In Event: 45.045 - Supporting Teachers to Support Students

Abstract

Verification laboratory instruction lacks opportunities for students to pose questions, generate hypotheses, and/or determine experimental procedures. Students in such settings often follow prescribed instructions towards a predetermined outcome. However, the Next Generation Science Standards (NGSS) calls for more inquiry-based approaches through science and engineering practices. This pre/post comparison study investigates the impact of a new guided inquiry-based laboratory curriculum versus an existing verification-based laboratory curriculum on the physical science content knowledge of 98 preservice elementary educators. The results show no differences in disciplinary chemistry/physics items but show a significant difference in integrated items for the guided-inquiry laboratory. Such findings indicate the value of guided versus verification-inquiry for integrated explanations and have important implications for teacher education in light of NGSS.
