WebJan 30, 2024 · ABSTRACT Developing inquiry-based science teaching (I.B.S.T.) methods in lower secondary schools challenges many schools and educational bodies. The paper addresses the influence of teacher collaboration on science teachers’ approaches and practices regarding I.B.S.T. The research emphasises three case studies: two science … WebThe authors of this book think about teachers as part of the immediate and large communities and systems in which they function. They consider the development of teachers professional knowledge as a continuous process that depends on the communities they are committed to and participate in, the discipline they are teaching, the social …

WebOct 18, 2006 · Actually the relation we show reduces for m = 0 and n = 3 to the well-known formula of Grangeat. In that sense, the paper contains a generalization of Grangeat's formula to arbitrary tensor fields in any dimension. We further briefly explain the importance of that formula for the problem of tensor field tomography.
