TALETE project aims at investigating different ways of the mathematics representations, in the topics, already, defined in the PISA, IEA TIMSS and National surveys concerning the maths skills of 15 years-old students. The worldwide surveys report that EU students often lack mathematical competence and key basic competences in science and technology. The learning of the mathematics literacy enables students to contribute effectively in actual society, improving their employment prospects. In this context, the project intends to develop with the teachers more attractive and fun pedagogical tools (serious game and machinima) for the maths literacy delivered in two virtual environments: e-learning platform and 3D world.
