D’Hainaut's Operationalization Model in Mathematics

The article is specific to the sciences of education and describes effective practices for students from the Faculty of Mathematics, “Vasile Alecsandri” University of Bacau.The aim was to investigate the efficiency of D’Hainaut's operationalization model with applications in mathematics, the formation of concepts, theorem proving, problem solving. The hypothesis can be reduced to the claim that the use of the operationalization model in relation to an object, product, cognitive operation in the teaching of Mathematics will lead to the building of effective skills in solving Mathematical problems and the development of thinking.
