Joint evaluation can be done after presenting the results of a group work (see activities 6, 8 and 12 for examples of group work) in a gallery walk (see activity 9). Each group presents their poster to the whole class.

While presenting, the observers take notes on a baseline evaluation sheet with different criteria to give professional feedback on fixed indicators, such as presentation skills, content, ability to answer questions, graphics.

Group discussion
A talk follows in the plenum, during which the class evaluates the results of the whole class (not of the single groups) in order to improve working strategies or presentation skills and to judge whether a certain topic has been covered in all its aspects or not, and accordingly integrate teaching and learning.

The evaluation of the class as a whole must take into account the presence of SEN learners in the groups and, as a rule, the specific features of every single learner. After the presentations and the plenum talk, it should be clear that a group might have highlighted some aspects on a certain topic, while the class as a whole might have covered it all in a fair way.
