I have had some instruction in PBL but have not formally implemented this approach in my classroom. I have included some of its elements, but I believe that this to really work, and make it posible for the teacher to manage the classroom work, there needs to be support from others in the school. Students need to be ready to follow the steps, and work in teams, and produce work of quality within a specific time-frame, ect. I think that this coming year we all will be more ready. Thank you for these articles. They are excellent.
