The ISIT project addresses two of the crucial needs defined by the Education and Training Benchmarks for 2020 and by the High Level Group of Experts on Literacy (HLGEL 2012):a) the problem of low literacy skills in many European countries b) the unsatisfying status of teachers' continuous professional development (CPD) in the EU.Thus ISIT pursues two goals:a) a specific goal: training 30 teacher educators from 3 European countries in content area literacy (CAL)b) a general, comparative goal: analysing good practice examples of how to implement innovations into different national structures of CPD.The innovative aspect of the project is to effectively combine these two goals.The project follows a multiplier approach: by training teacher educators (narrow target group) it will reach out to secondary school teachers (second target group) which will have a positive impact on the long-term target group of students with low literacy skills (broadest target group). ISIT builds upon the results of the Comenius project BaCuLit prodiving a comprehensive curriculum in CAL for CPD, including course materials and trainer handbooks. ISIT aims at implementing this concept into the CPD structure of Germany, Hungary and Romania, where a total of 30 teacher educators from 25 different training institutions will be made familiar with CAL instruction. The project follows an action research approach, which means not to separate research from action. Therefore the trainers will analyse together with scientists the steps and obstacles in implementing CAL courses in their institutions. Thus, ISIT intends to explore the general opportunities and obstacles in implementing innovation into teachers CPD in these 3 countries. A further objective is the dissemination of CAL into 5 other countries: Partners from Belgium, Cyprus, Finland, Greece, and Portugal will participate gaining comparative insights and providing input from the perspective of their countries.
