An Anthropological Approach to Analyse a Chemical Knowledge during Experimental Design

Abstract : In the context of experimental design, students have to write the procedure of an experiment. For this purpose they need to reuse and adapt existing procedures. We studied the procedures produced by students to answer a chemical problem of titration by spectrophotometry. We analysed the content of the written procedures with the Anthropological Theory of the Didactic. This facilitated the analysis of the strategies used by the students, and specifically when the procedure is not satisfactory. To be successful, it is necessary for students to understand the knowledge underlying an experimental task, i.e. to relate the technological level to the technical level. We illustrate this with examples.
