OBJECTIVES: How students build rnathematical knowledge and what level of learning is achieved by them using Dubinsky's cognitive model (APOS). RESEARCH DESIGN: Our work is an Action Research in a case study. The teaching strategy includes a theoretical analysis of the concept under study and teaching resources used, an instructional design and assessrnent using the tools of analysis. RESULTS: - The instrurnent of analysis shows at least a weak schema Intra is learnt. - The cornputer graphic facilitates learning, allows knowledge building, and encourages the transit between cognitive modes. CONCLUSIONS: - Despite the errors, all cases able to consolidate learning level. - The development of the "derivative scheme" does not entail to know many elements of the concept but to be able to coordinate them to solve problerns. - The computing environment is a tool that supports student learning.
