Abstract. This paper presents some phases of a remedial intervention in algebra in three 9th grade classes. The experiment was devoted to pupils who showed difficulties in memorization and application of the main products formulas. First, we planned an experiment based on the use of an interactive learning environment, the Aplusix microworld, whose main feature is to show students if they have made mistakes. However, since the feedback of the software seemed not to be enough, we integrated the microworld with a new artefact, the Help Window, aiming at supporting the solution process when interacting with the microworld. In this paper we will mainly analyze the role played by this artefact.
