Problem-Based Learning: Six
Steps to Design, Implement, and Assess
Twenty-first century skills
necessitate the implementation of instruction that allows students to apply
course content, take ownership of their learning, use technology meaningfully,
and collaborate. Problem-Based Learning (PBL) is one pedagogical approach that
might fit in your teaching toolbox.
PBL is a student-centered,
inquiry-based instructional model in which learners engage with an authentic,
ill-structured problem that requires further research (Jonassen & Hung,
2008). Students identify gaps in their knowledge, conduct research, and apply
their learning to develop solutions and present their findings (Barrows, 1996).
Through collaboration and inquiry, students can cultivate problem solving
(Norman & Schmidt, 1992), metacognitive skills (Gijbels et al., 2005),
engagement in learning (Dochy et al., 2003), and intrinsic motivation. Despite
PBL’s potential benefits, many instructors lack the confidence or knowledge to
utilize it (Ertmer & Simons, 2006; Onyon, 2005). By breaking down the PBL
cycle into six steps, you can begin to design, implement, and assess PBL in
your own courses.
Step One: Identify
Outcomes/Assessments
PBL fits best with
process-oriented course outcomes such as collaboration, research, and problem
solving. It can help students acquire content or conceptual knowledge, or
develop disciplinary habits such as writing or communication. After determining
whether your course has learning outcomes that fit with PBL, you will develop
formative and summative assessments to measure student learning. Group
contracts, self/peer-evaluation forms, learning reflections, writing samples,
and rubrics are potential PBL assessments.
Step Two: Design the Scenario
Next you design the PBL scenario
with an embedded problem that will emerge through student brainstorming. Think
of a real, complex issue related to your course content. It’s seldom difficult
to identify lots of problems in our fields; the key is writing a scenario for
our students that will elicit the types of thinking, discussion, research, and
learning that need to take place to meet the learning outcomes. Scenarios
should be motivating, interesting, and generate good discussion. Check out the
websites below for examples of PBL problems and scenarios.
Step Three: Introduce PBL
If PBL is new to your students,
you can practice with an “easy problem,” such as a scenario about long lines in
the dining hall. After grouping students and allowing time to engage in an
abbreviated version of PBL, introduce the assignment expectations, rubrics, and
timelines. Then let groups read through the scenario(s). You might develop a
single scenario and let each group tackle it in their own way, or you could design
multiple scenarios addressing a unique problem for each group to discuss and
research.
Step Four: Research
PBL research begins with
small-group brainstorming sessions where students define the problem and
determine what they know about the problem (background knowledge), what they
need to learn more about (topics to research), and where they need to look to
find data (databases, interviews, etc.). Groups should write the problem as a
statement or research question. They will likely need assistance. Think about
your own research: without good research questions, the process can be unguided
or far too specific. Students should decide upon group roles and assign
responsibility for researching topics necessary for them to fully understand
their problems. Students then develop an initial hypothesis to “test” as they
research a solution. Remember: research questions and hypotheses can change
after students find information disconfirming their initial beliefs.
Step Five: Product Performance
After researching, the students
create products and presentations that synthesize their research, solutions,
and learning. The format of the summative assessment is completely up to you.
We treat this step like a research fair. Students find resources to develop
background knowledge that informs their understanding, and then they
collaboratively present their findings, including one or more viable solutions,
as research posters to the class.
Step Six: Assessment
During the PBL assessment step,
evaluate the groups’ products and performances. Use rubrics to determine
whether students have clearly communicated the problem, background, research
methods, solutions (feasible and research-based), and resources, and to decide
whether all group members participated meaningfully. You should consider having
your students fill out reflections about their learning (including what they’ve
learned about the content and the research process) every day, and at the
conclusion of the process.
Although we presented PBL as
steps, it really functions cyclically. For example, you might teach an
economics course and develop a scenario about crowded campus sidewalks. After
the groups have read the scenario, they develop initial hypotheses about why
the sidewalks are crowded and how to solve the problem. If one group believes
they are crowded because they are too narrow and the solution is widening the
sidewalks, their subsequent research on the economic and environmental impacts
might inform them that sidewalk widening isn’t feasible. They should jump back
to step four, discuss another hypothesis, and begin a different research path.
This type of process-oriented,
self-directed, and collaborative pedagogical strategy can prepare our students
for successful post-undergraduate careers. Is it time to put PBL to work in
your courses?
