The main goal of the training in CLIL program is to introduce teachers to the innovative methods and tools it provides. Via the CLIL post-educational program, participants learn how to adapt CLIL’s teaching methods and tools in the teaching task, either their goal is to teach a second language, or they want to teach other lessons, like Geography, History, Math etc. Moreover, participants will be able to master the integration of CLIL methods in teaching and use digital tools in favor of the class and the teaching task. As a result, language education and acquisition will constitute an immediate derivative of teaching other lessons (e.g. Math). In other words, via its methods and tools, CLIL teachers will be in position to teach –at the same time with whichever lesson- English language or whatever language-target they want. In such a manner, CLIL teachers will manage to exercise and educate students who will be able to constitute future citizens of a global society. This is one of the most important task that every school or college should aim to. Finally yet importantly, completing the CLIL program, participants will acquire the ability to implement the CLIL methods and tools, together with other digital and audiovisual tools in the teaching task, transforming their class into an innovative, contemporary and very effective procedure.
