Debriefing is an important part of the PBL process. Once a project is over, you need to analyze what worked and what did not. For instance, in planning my Create-a-Civilization project, I am unsure about the overall project timeline. So, assessing how well the project worked in my 3 month time frame will be part of my debriefing process. To determine whether the time frame is appropriate, I will look at what each student learned and was able to accomplish during the project, as well as solicit feedback from the students. Since I am not collaborating with another teacher on this project, I will ask for feedback from colleagues, but the student, and even parent, feedback will be more useful.
To begin the debriefing, I will ask students to write about how they felt about the project. Although I want this discussion to be as open-ended as possible, I will provide students with some questions to answer so that they don’t just say they liked it or didn’t like it and then not give any more input. I will ask the students to discuss how they felt about the amount of time provided, the access to resources to complete the project, the grouping strategies, and the materials provided. I will try to keep questions about these components as open-ended as possible.
On my own, I will look at the quality of the assessments, both formative and summative, and the students performance on those assessments. I will decide whether students needed more support, whether the assessments were clear and well-structured, and whether the assessments really assess the learning objectives.
Assessment of a PBL is not a one-time process. It should occur before and after you use the unit. I also think it is useful to reflect on the effectiveness of the PBL throughout the school year, each time the students are required to retrieve content knowledge or use skills that should have been learned during the unit. Is it an effective PBL unit if the students cannot replicate the skills months later? In order to keep a record of my reflections, I will probably create a hidden blog page on the PBL website. This will allow me to keep all of my materials for the PBL in one place. If I decide that my reflections would be useful to someone else, I will make the page public.
