Two Years Of Use Of The Aplusix System

Abstract : APLUSIX is a learning environment for helping students to learn algebra. This system is designed and developed in the IMAG-Leibniz laboratory. Its basic training mode consists of letting the students perform their owns calculations, thanks to a two-dimensions editor of algebraic expressions, providing feedback on the correctness of the calculations and on the end of the resolution. APLUSIX has now been used for two years at school, in different contexts. One use was made by four teachers during two entire school years in France, in the computer room, for each algebraic activity of their grade 10 classes. Their main outcomes were very positive. APLUSIX has also been used in the hospital for children having a long illness. The results were very positive too. Several experiments of Aplusix have been realised with a pre-test and a post-test to measure the learning. One experiment, in France, with 28 students and 50 minutes training, shows an improvement of the abilities increasing of 70% to 250% depending of the type of exercise. Another one, in Brazil, with 1120 students and 25 minutes training, shows a global improvement of 30%. These good results led us to realise a version of APLUSIX for home usage in addition to the version for schools. This home version is now available as a shareware in several languages. The school version will be commercialised at the beginning of 2005.
