| This research project is connected to the TWIN project. The hypothesis is that the use of IT tools (in particular the graphic calculator) in a setting of cooperative, small group work will improve students' flexibility in solving mathematical problems in an engineering context. Teachers of four schools are being supported in using the graphic calculator as a problem solving and learning tool and for applying mathematics as well as in guiding small group work. Classroom observations and interviews with teachers and students will be used to test the hypothesis. |
