註釋Supported by a constructivist view of learning and epistemology of science, this dissertation describes a curriculum resource for high school and first-year college chemistry teachers. The resource, which contains seven cohesive activities for investigating chemical change in the laboratory, is centered around two colorful and reliable reactions: the synthesis and decomposition of zinc iodide. These reactions have many advantages over the traditional syntheses between elements such as the iron sulfide and magnesium oxide syntheses commonly performed by introductory chemistry students. The primary advantage is that students can synthesize a compound of zinc iodide and decompose that very same sample back into its constituent elements, zinc and iodine. Moreover, this pair of reactions lend themselves to both qualitative and quantitative investigations.
