摘要：In this paper, we describe and analyze the results of an Action-Research teaching experience concerning compound proportional situations, which involved students in 7th and 8th grades. The teaching proposal is developed according to the analysis of didactic objects and the problems of the traditional teaching practice. This piece of research had been carried out over four academic years. Two cycles of Action-Research were completed during this period. The wide sample, with about 120 students involved in each cycle, and the variety of information collection tools used during the action phase, allow us to reach strong conclusions on the feasibility, strengths and improvable aspects of the teaching proposal.
