Conceptions of (n=13) grade-11 chemistry students via interviews were grouped into 6 categories related to students' preferred explanations for solubility phenomena. Argues that an understanding of the typical conceptions used by students should form an integral component of chemistry teaching, both as points of origin for lesson planning and for…

Describes a model-centered, computer-supported semester-long science curriculum (Model-based Analysis and Reasoning in Science) for middle school students designed to encourage conceptual understanding and to foster the development of model-based reasoning skills. (ZWH)
