Birgit Griese presents MP2-Math/Plus, a support project for first-year students in engineering at Ruhr-Universität Bochum that aims at preventing unnecessary drop-out. Conceptualisation and development of the project follow a design research approach according to Gravemeijer, Cobb, and van den Akker. The interventions focus on learning strategies which are collected in a pre-post design with the aid of the LIST questionnaire by Wild and Schiefele. These and other data are utilised for the evaluation of MP2-Math/Plus. The results confirm the adaptations of the project procedures in successive cycles, stress the importance of effort and motivation, and assess the success of the project. Contents Encountering the Problem Theoretical Concepts Research Approach and Objectives Design Development Methodology and Results Project Evaluation Target Groups Researchers, academics, and students in the fields of didactics of mathematics; lecturers in mathematics affined courses Teachers of mathematics and their supervisors/instructors The Author Dr. Birgit Griese had worked as a mathematics teacher for many years before she received her doctoral degree at Ruhr-Universität Bochum. She now works at Paderborn University, researching mathematics teachers’ professional development.
