The videos are really interesting and they clearly show how PBL increase motivation and help the students in retaining the knowledge. However, there are some critical issues to deal with: lack of time and materials, teachers involvement.

I believe teachers are reluctant to use PBL in class because it is something different, something that does not come in textbooks. It is something that requires extra work for teachers and sometimes teachers just prefer to follow the textbook. Changes are always difficult and there is also a part of fear from our part I guess. It is a change of everything where we should leave the textbook aside and change the role of the students from passive to active.

I feel assessment will be the most challenging component for me to deal with. The PBL is based on collaboration and so on group work, but the curriculum requires individual  grades. Furthermore, as a learning process, PBL needs an assessment integrated thoughout the entire unit.  PBL is based on formative assessment and our evaluation system on summative assessment.
These are the difficulties I "may bumb into" using PBL with my students.

I'm Francesca and I teach English as second language in a lower secondary school in Tuscany, in Italy. I have six classes and my students are from 11 to 14 years old. I usually use a communicative approach to teach the language. I noticed that using more traditional methods  means to have "students who do not remember what they "learned" the day before"  so I have been trying to give them the opportunity to use English in meaningful contexts. That is why I am really interested in PBL and I am learning how to use this approach to engage, motivate the students and help them not only to improve their language knowledge but also their critical thinking, collaboration and communication skills.

In particular, I would like to work using PBL approach with a second class made up of 25 students with different English language competentences but really interested and stimulated by challenges. I am thinking about a unit where students have to plan a real situation using English.

 We can weaken our students' confidence by focusing on their failure or negative behaviours in front of their classmates; by giving them projects that are not relevant for their learning process; by creating a competitive environment

I would like to share my experience with peer assessment not as a teacher but as a learner, I particularly liked the peer assessment  activities in this course. They gave me the opportunity to reflect on my work not just by reading the feedbacks but especially by rewieving my collegues' works. I can easily confirm that peer assessment is a powerful learning activity for the reviewer and for the reviewee. I am going to try it with my students!
