Keys to PBL What is your experience with PBL? Why would you like to implement it in your classroom? Have you faced any difficulties in its implementation? If so, which of the 5 core elements were the most difficult to adapt?

I like the idea of PBL learning and I've learned about it but I still have to improve some phases of it. For example, I have difficulties with big classes how to motivate them to participate with more enthusiasm in their work. While some groups are doing great, some of them are making me crazy. They are talking in their mother tongue and don't do much of the task. They don't participate all in it. But I'm working on this and I think I'll find ways how to make them all work better and how to collaborate.
