EU Ministers set the target to reduce the average of students with difficulties in reading, maths and science in order to reach fewer than 15% by 2020. TALETE proposal 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. The project, therefore, addresses the Comenius priority 3 “Support to literacy and “transversal key competences”.The data, collected by TIMSS survey, show that the Asian countries placed at the best positions of the ranking. In response to this, the project aims at developing innovative pedagogical tools based on the topics defined in the PISA, TIMSS and National surveys in order to enable 15 years-old students to acquire mathematical literacy improving attractiveness and efficiency in the ISCED levels 2 and 3 of compulsory education.Main outcomes are:- E-learning platform delivering the e-course for teachers- 3D virtual world environment for their students in compulsory educationEnvisaged impact:- Teachers will develop and test innovative didactic tools that can help raise the interest level and motivate students to acquire mathematical skills- Students will test directly with their teachers the attractiveness and efficiency of new didactic tools and will also develop transversal skills (e.g. communicative, learning to learn, social and digital skills) useful for future professional development.
