We all would agree that the feedback is essential for our growth. In the successful child’s development the so called “cooperation triangle” (child – teacher – parents) is very important. And we think that high quality feedback may build more productive cooperation between teachers and parents and have very positive effect for more successful child’s development. Within this project we would like to explore what forms of the feedback are used in the preschools and to share the best practices how to prepare and deliver high quality feedback to parents about their children development. The outcomes of this project will be summarized and published in the methodological recommendations for teachers.
