Project Based Learning - Challenges to Change How Students Learn

Project-Based Learning, a somewhat new concept in how we teach.  I have heard many excellent things about what PBL has to offer working usually with real world problems, students developing deeper understanding into curriculum, strengthening time-management and critical thinking skills, and learners taking ownership of their learning.  However, until I read Suzie Boss's blog "Project-Based Learning: A Case for Not Giving Up", I had never really thought of the challenges to implementing PBL into the classroom.

Ms. Boss details how, in the beginning, implementing PBL can be frustrating, not only for the teachers but the students as well.  Change is never easy.  So, when we try to change how our kids learn, it can be challenging.  Implementing PBL should be a gradual process as we teach the students to become responsible for their learning without use to traditional classroom tools such as "text books, tests and teacher-driven instruction." (Boss, 2010).

"Project-based learning can pose challenges for teachers as well as students, especially when both are new to this approach...some project management skills may need to be taught explicitly. Formative assessment has to happen early and often, and a teacher needs to be ready with support for students who are struggling. Handing over responsibility to the learner happens gradually, not all at once." (Boss, 2010)

Have you implemented any PBL into your classroom?  What challenges have you encountered?  What would you consider the benefits?  Do the benefits outweigh the challenges?
