The project “Study, practice, know” is the KA1 project of the Cirkevna spojena skola in Vranov nad Toplou, Slovakia. The main objective of this project is to prepare a series of educational activities for the teachers of foreign languages at this school. We have prepared a 1-year project beginning on 15th September 2014 and finishing on 15th September 2015. Altogether we have selected 4 participants – three English teachers and one teacher of the German languages. All courses that we plan to organize are going to be held from June to August 2015. All participants are the teachers of foreign languages at our school where they have been teaching for a couple f years. All project participants are going to take part in 2-week courses aimed at various aspect of ESL. The courses cover areas such as basic language development, methodology areas as well as CLIL techniques. There is one course aimed at developing oral fluency of English at a secondary level, one course for primary teachers of English, one course for CLIL with the English language and then one teacher’s refresher course of the German language. We are sure this project will bring a number of positives to the development of our school. This project will help to increase the professional performance of the participants themselves by developing their language and cooperative skills. Moreover, the whole school will have a great benefit from sharing good practice and other ideas absorbed during the courses, which means that there are other teachers of our school who will gain a lot from this project. Finally, the participation in this project will serve a good example of how teachers can contribute to the development of their own personality as well as the whole institution, which can later be used as the beginning for preparing another similar project for other teachers.
