In Project-Based Learning Applied to the Language Classroom, the authors propose a way to develop PBL in the language classrooms taking into account all of the obstacles and specifics involved in teaching a foreign language. It is about teaching English as a second or foreign language using Project-Based Learning (PBL). We approach this combination because many people seem to think about implementing PBL in their language classes and ask questions about how to do it, but feel that there aren't enough materials based on this methodology. In fact, most researchers and writers we have come across discuss the applications of PBL in the students' mother tongue to subjects such as Math, History, Literature,Social Studies, and Science. However, there are few published works about the specifics of PBL in foreign language classes. Besides, it seems obvious to us that the main difficulty in developing projects in a second or foreign language lies exactly on the fact that communication may be hindered when students do not have enough knowledge in the target language.
