Influences. Maria recognizes that the experience of the collaborative project was a source of professional “added value”. The project made it easier to plan, implement and assess new teaching experiences. As she says: “This forces us to think”. And later she adds: “I love this work! But did I learn anything really new? No. Most of it we already knew… But we were unable to put it into practice. (…) This work questions myself” (M23). She goes on: “Our lessons are planned the way we get used to from our earlier experiences. (…) Without a possibility to share, review, criticise, the years go on and we stay close to the starting point” (M25). How relevant the project was with respect to the development of her own classroom communication skills is witnessed by her words in the analysis of this lesson: “Now I pay more attention to what students say. My own comments became more succinct and crisp” (M22).
