Teaching and Learning Floating and Sinking: Didactic Transformation in a Density-Based Approach

This essay synthesizes more than a decade of research, most which has been published, on the teaching and learning floating sinking (FS) phenomena. The research is comprised iterative design, development, implementation evaluation Teaching-Learning sequence (TLS) for density within FS It was initiated frame European Community supported “Materials Science” project. Due to many, different aspects project, each publication focused particular part study (e.g., effectiveness iteration process). didactic transformation phenomena presented discussed here. In doing so, it essential mention: (a) students’ ideas as main cause scientific knowledge transformation, (b) scientific/reference knowledge, (c) be taught its limitations. Thus, we intend describe justify process briefly synthesize published (from previous papers) unpublished results show effectiveness.
