In the field of science education there is concern expressed by teachers regarding the difficulties presented by a high number of students in understanding scientific concepts. This research is based on the theory of conceptual fields proposed by Vergnaud (1983). Its goal is to analyze the schemes used by college students in resolving problem situations on mechanical waves diffraction before formal education. To this end, two instruments, a questionnaire and a semistructured interview were used to examine the goals and anticipations, rules of action, possibility of inference and operational invariants used. The results of a qualitative study of multiple cases, interpretative, where the principle of gradual selection sampling was used with t...
