Practical PBL Series: Design an Instructional Unit in Seven PhasesSeptember 11, 2012 | Amber Graeber
As a new teacher, I once believed that teaching and learning were one and the same. I taught, and the students learned. In creating a student-centered classroom, I began to embrace project-based learning. However, I did so in a very superficial way. I thought I had PBL nailed if my students did a presentation or poster at the end of an instructional unit. My room was full of student work. Anyone who walked in my room could see learning . . . or could they?
I enrolled in professional development courses, started a graduate degree, and collaborated with more experienced colleagues. I reflected on my practice and began to understand that teaching and learning were two very separate things. I may have been teaching every day, but I soon realized that I had no idea whether or not my students were actually learning. I came to realize that the posters on my classroom walls were not the results indicators I thought they could be.
In the spring of 2008, my colleagues and I were approached by a local university to participate in designing a project-based learning course. Our team researched PBL, met with experts in education, and set about the task of designing a course driven through projects. The intention was to give students authentic roles and engage them in solving relevant problems, creating a link between the classroom and our larger community and world. The goal was to transform our classrooms from posters and presentations to problem-based experiences.
The Seven-Phase Model
You can transform your classroom. While there are many approaches to project-based learning, we have had the most success with the model our team developed -- a model called "The Seven Phases of a Project Cycle." Each and every one of our instructional units is designed using these seven phases.
To begin, ask yourself these questions:
- What instructional unit do I want to transform?
- What engaging, relevant, real-world problem could students attempt to solve that is related to the concepts and skills in the unit?
- What authentic roles can students take on to try solving this problem?
- How might students be asked to work collaboratively to try solving this problem?
Phase 1: Introducing the Driving Question
The instructional unit must have a strong driving question. Many practitioners also refer to this as an "essential question." This question should be compelling, open-ended and meaningful. It must be a higher-level question requiring students to think deeply. A strong driving question has no right or wrong answer. It is important to ask students to respond to this driving question before any instruction has taken place. This provides you with an opportunity to ascertain differing levels of prior knowledge and plan appropriately for instruction.
Phase 2: Introducing the Culminating Challenge
The culminating challenge needs to be some type of authentic assessment or performance in which students clearly demonstrate learning. Examples include a moot court, election simulation, authoring a children's book, developing a web site, a town hall meeting, etc. Phase 2 is also when students are provided with guided choice concerning the options for authentic role(s).
Phase 3: Developing Subject Matter Expertise
Phase 3 is the longest part of your challenge cycle (instructional unit). In this phase, individual and team tasks are created to lead students to success on both the culminating challenge and summative assessment. Students embody authentic roles and thus have a "need to know" more about the concepts and skills. Utilize inquiry methods to help students explore new concepts, but provide enough background information on the new vocabulary and concepts that students can figure out how to move forward.
Phase 4: Doing the Culminating Challenge
This is the big day -- the chance for students to demonstrate their learning in a performance assessment. If possible, bring in subject matter experts to help assess the quality of student work. We have reached out to local professionals, college students majoring in the content area, or even building administrators or fellow teachers. An outside perspective will "up the stakes" for students who are used to performing for you.
Phase 5: Debriefing the Culminating Challenge (Ideally with Subject-Matter Experts)
This moment for debriefing is easy to overlook or breeze past due to never-ending time constraints. However, the reflective practice of debriefing is extremely valuable for students and teachers alike. If time allows, invite the subject matter expert to participate in this experience. Immediate feedback from the expert can be especially powerful for students who routinely get the teacher's feedback on their performance. Taking 15 to 30 minutes to debrief through a writing exercise, a discussion or a combination of the two is vital to student growth.
Phase 6: Responding to the Driving Question
As the challenge cycle comes to a close, ask students to respond to the driving question once again. They should have new vocabulary and a deep, conceptual understanding of the material covered during the cycle. The responses will be more sophisticated than those given on the first day of the cycle. As students complete this exercise, hand back their initial responses. Allow them time to examine the differences between the two writing samples and acknowledge the learning.
Phase 7: Summative Assessment
Whether this is a common summative assessment, district benchmark assessment, practice Advanced Placement exam or other unit test, a summative measure is an important way to assess student learning. It provides the teacher with another measure to determine individual student achievement of the learning objectives. If the individual and team tasks align with your instructional goals, then the summative assessment should measure student proficiency on those concepts and skills deemed important.
