From the perception of science to the design of teaching materials
To design teaching materials starting from the subject matter in Science field, from the contents of textbooks or by studying the syllabuses are regular practices within schools. The SEDEC project proposes concrete and innovative modalities of conceiving teaching materials starting from teachers perception of science and by talking with them about their ideas and needs regarding teaching Science. A deep discussion of the relationships between science education and European citizenship has been another important ingredient of this new process of didactic design.
