Assessing and evaluating the quantity and quality of students’ learning is another very important task of the teacher. It is also important to involve the students in assessing each other’s level of learning. Regarding group processing, the teacher makes sure that all the students receive feedback on their work, analyze the data on group functioning, set an improvement goal, and participate in a team celebration. The groups have to list three things they did well in working together and one thing they will do better tomorrow.
