From this point of view, it is disadvantageous to do long-term projects with students, because it really takes a lot of hours. BUT on the other hand, if the project is well prepared (including work assignments), the pupils will enjoy it and their work will be very high quality and sophisticated. All you need is a good introductory motivation for each lesson, which always kicks the pupils and reminds them why we do it and what we want to achieve. The second reflection is a day for nothing.
