What is Problem-Based Learning?

Problem-Based Learning (PBL) is an instructional approach where students learn by working through complex, real-world problems. Rather than first teaching content and then applying it, PBL reverses this sequence: students encounter a problem first, identify what they need to learn to solve it, and then acquire that knowledge through self-directed study and collaborative work.

Core Characteristics of PBL

In authentic PBL, students engage with problems that are:

  • Complex and open-ended – No single correct answer or clear solution path
  • Realistic – Reflecting challenges professionals encounter in the field
  • Student-centered – Learners drive the investigation and decision-making
  • Collaborative – Small groups work together to analyze and address the problem
  • Iterative – Solutions are developed, tested, and refined over time

The instructor acts as a facilitator or coach rather than a lecturer, guiding students through questioning and providing resources as needed.

The PBL Process

A typical PBL cycle follows these stages:

  1. Problem Presentation – Students encounter a scenario or challenge with limited information
  2. Identify Known and Unknown – Groups discuss what they understand and what they need to learn
  3. Generate Hypotheses – Students propose possible explanations or approaches
  4. Define Learning Issues – The group identifies specific questions to research
  5. Self-Directed Learning – Students independently research their learning issues
  6. Share and Apply Knowledge – Groups reconvene to share findings and work toward solutions
  7. Reflect and Assess – Students evaluate both their solution and their learning process

When to Use Problem-Based Learning

PBL Works Well When:

You Want to Develop Higher-Order Thinking Skills
PBL excels at building critical thinking, analysis, synthesis, and evaluation skills. If your course goals emphasize applying knowledge rather than just recalling facts, PBL is highly effective.

Students Need to Integrate Multiple Concepts
When learning objectives require connecting ideas across topics or disciplines, PBL provides a natural framework. For example, a nursing scenario might require anatomy, pharmacology, and patient communication skills simultaneously.

Professional Skills Are Course Priorities
PBL naturally develops workplace competencies like collaboration, communication, problem-solving, self-directed learning, and adaptability—skills community college students need for career success.

Content Has Clear Real-World Applications
Courses in healthcare, business, technology, social sciences, and applied sciences benefit greatly from PBL because authentic problems are readily available and motivating for students.

You Can Dedicate Sustained Class Time
PBL requires extended engagement with problems, typically spanning multiple class sessions. It works best when you can allocate several hours or weeks to a problem scenario.

Students Have Foundational Knowledge
While students don't need to know everything before starting, they should have basic skills to begin investigating the problem. PBL builds on existing knowledge rather than creating it from nothing.

Consider Alternatives When:

Foundational Skills Must Come First
In introductory courses where students lack basic vocabulary or fundamental concepts, some direct instruction may be necessary before PBL can be effective. Consider hybrid approaches that combine lectures or other teaching strategies with problem-solving.

Time Is Severely Limited
PBL requires time for investigation, discussion, and iteration. If you have only one or two class meetings to cover a topic, more focused active learning strategies (case studies, simulations, structured problem sets) may be more practical.

Assessment Infrastructure Isn't in Place
PBL requires assessing process as well as product, including collaboration, research skills, and reflection. If you can only use traditional tests, PBL's full benefits won't be realized or measured.

Student Resistance Is High
Some students, especially those accustomed to lecture-based learning, may initially resist PBL's demands for self-direction. While this can be overcome with clear expectations and scaffolding, be prepared to address concerns and build buy-in.

Practical Applications by Discipline

Healthcare Programs: Patient scenarios requiring diagnosis, treatment planning, and ethical decision-making

Business: Market analysis challenges, organizational problems, budgeting dilemmas, or entrepreneurial ventures

STEM: Engineering design challenges, environmental problems, data analysis projects, or troubleshooting technical systems

Social Sciences: Community issues, policy analysis, cultural conflicts, or social justice challenges

Humanities: Interpretive problems, rhetorical situations, historical mysteries, or creative design briefs

Getting Started with PBL

If you're new to PBL, consider these approaches:

Start Small – Try one PBL unit in a semester rather than converting your entire course immediately.

Use Scaffolding – Provide structure for newer students: research guides, check-in milestones, question prompts, or sample analyses.

Be Transparent – Explain why you're using PBL and how it benefits students. Make the learning process visible.

Prepare Rich Problems – Invest time in crafting scenarios that are engaging, appropriately complex, and aligned with your learning objectives.

Build in Reflection – Include regular opportunities for students to reflect on both what they're learning and how they're learning it.

Assess Thoughtfully – Use rubrics that evaluate both the solution and the process and consider incorporating peer assessment and self-assessment.

Resources for Further Learning

  • Explore problem libraries from institutions like the University of Delaware's PBL Clearinghouse
  • Connect with colleagues who use PBL
  • Connect with an instructional designer in AISD
  • Review disciplinary journals for published PBL cases in your field

Problem-Based Learning represents a significant shift from traditional instruction, but for many students and courses, it offers a useful way to develop the knowledge and skills needed for both academic success and career readiness.
