In this talk the experience of applying a new teaching strategy to a basic mathematics course at the Open University of Catalonia will be described. This strategy requires students to engage with practice and assessment tests with automatic feedback. The main aim of the research is to look into the extent to which the key elements of this teaching strategy influence the students’ course completion and academic achievement. In order to achieve this purpose, qualitative and quantitative variables over one term have been measured weekly. Our findings suggest that this teaching strategy significantly reduced the number of students who dropped out and improved academic results. More specifically, regular practice activities at the beginning of the semester help to engage students in the completion of the course.
