If feedback among colleagues should contribute to better teaching and learning, there have to be reciprocal agreements about what aspects should be observed and evaluated and in what way. Whereas well-known scientists left out collegial feedback, Andreas Helmke, a German educationalist, dedicates part of his academic career to this subject. He furnishes a great variety of observation sheets and evaluation programs, also in English, that can be adapted for collegial feedback in the foreign-language classroom. In order to come closer to face-to face feedback discussions among colleagues, valuable suggestions of researchers and practitioners should be taken into account.
