What is PBL?

Problem-based learning (PBL) is an approach that challenges students to learn through engagement in a real problem. It is a format that simultaneously develops both problem solving strategies and disciplinary knowledge bases and skills by placing students in the active role of problem-solvers confronted with an ill-structured situation that simulates the kind of problems they are likely to face as future managers in complex organizations.

Problem-based learning is student-centered. PBL makes a fundamental shift--from a focus on teaching to a focus on learning. The process is aimed at using the power of authentic problem solving to engage students and enhance their learning and motivation. There are several unique aspects that define the PBL approach:

• Learning takes place within the contexts of authentic tasks, issues, and problems--that are aligned with real-world concerns.
• In a PBL course, students and the instructor become colearners, coplanners, coproducers, and coevaluators as they design, implement, and continually refine their curricula.
• The PBL approach is grounded in solid academic research on learning and on the best practices that promote it. This approach stimulates students to take responsibility for their own learning, since there are few lectures, no structured sequence of assigned readings, and so on.
• PBL is unique in that it fosters collaboration among students, stresses the development of problem solving skills within the context of professional practice, promotes effective reasoning and self-directed learning, and is aimed at increasing motivation for life-long learning.

Problem-based learning begins with the introduction of an ill-structured problem on which all learning is centered. The problem is one that students are likely to face as future professionals. Expertise is developed by engaging in progressive problem solving. Thus, problems drive the organization and dynamics of the course.

Students, individually and collectively, assume major responsibility for their own learning and instruction. Most of the learning occurs in small groups rather than in lectures. As teacher, my role changes from "sage on stage" to a "guide by the side."

My role is more like that of a facilitator and coach of student learning, acting at times as a resource person, rather than as knowledge-holder and disseminator. Similarly, your role, as a student, is more active, as you are engaged as a problem-solver, decision-maker, and meaning-maker, rather than being merely a passive listener and note-taker.

Why PBL?

Traditional education practices, starting from kindergarten through college, tend to produce students who are often disenchanted and bored with their education. They are faced with a vast amount of information to memorize, much of which seems irrelevant to the world as it exists outside of school. Students often forget much of what they learned, and that which they remember cannot often be applied to the problems and tasks they later face in the business world. Traditional classrooms also do not prepare students to work with others in collaborative team situations. The result: students tend to view MBA education as simply a "right of passage," a necessary "union card," and an imposed set of hurdles with little relevance to the real world. Education is reduced to acquiring a diploma (merely another commodity to be purchased in the marketplace), and the final grade becomes the overriding concern (rather than learning).

Research in educational psychology has found that traditional educational approaches (e.g., lectures) do not lead to a high rate of knowledge retention. Despite intense efforts on the part of both students and teachers, most material learned through lectures is soon forgotten, and natural problem solving abilities may actually be impaired. In fact, studies have shown that in 90 days students forget 90% of everything they have been told (Smilovitz, 1996). Motivation in such traditional classroom environments is also usually low.

Perhaps one of the greatest advantages of PBL is that students genuinely enjoy the process of learning. PBL is a challenging program which makes the study of organization design and change intriguing for students because they are motivated to learn by a need to understand and solve real managerial problems. The relevance of information learned is readily apparent; students become aware of a need for knowledge as they work to resolve the problems.

How Does PBL Work?

A PBL course is designed into a series of real-world, hands-on, PBL investigations. You will be working in small groups/teams with other students on problems that you are likely to encounter as a professional manager. You will begin a PBL investigation by being presented with an ill-structured organizational problem or scenario. Such a presentation may be in the form of a written statement, a video clip of a real manager at a company, or a guest speaker. Every PBL team will appoint a chairperson/leader and sometimes a recorder/secretary. Your PBL team will be guided in the use of a reiterative problem-solving process. Your team will applyy this problem solving process to find, analyze, and solve the presenting problem. Some PBL investigations may culminate in a student-created project/product, exhibitions, or other artifacts that address the driving questions. In some cases, the PBL investigation will culminate in an oral performance with managers from the business community in attendance.

As you work with each problem you can:

• Develop your diagnostic reasoning and analytical problem-solving skills.
• Determine what knowledge you need to acquire to understand the problem, and others like it.
• Discover the best resources for acquiring that information.
• Carry out your own personalized study using a wide range of resources.
• Apply the information you have learned back to the problem.
• Integrate this newly acquired knowledge with your existing understanding.
• In short, you will be learning in a highly relevant and exciting manner to problem-solve and to develop self-directed study skills that build toward the skills and knowledge that you will need as a practicing manager.

The problem-solving process can be summarized according to three broad and reiterative phases.

Phase 1. First, your group will gather information and list it under a heading entitled: "What do we already know?" In this phase, you will entertain the problem in light of the knowledge that you already have from your own experience. Your group will discuss the current situation surrounding the problem as it has been presented. This analysis requires discussion and agreement on the working definitions of the problems, and sorting out which issues and aspects of the situation are worthy of further investigation. This initial analysis should yield a problem statement that serves as a starting point for the investigation, and it may be revised as assumptions are questioned and new information comes to light.

Phase 2. Next, you will engage with the problem by also identifying under a second heading, "What do we need to know (to solve this problem)?" Here you will list questions or learning issues that must be answered to address missing knowledge, or to shed light on the problem. It is in this phase that your group will be analyzing the problem into components, discussing implications, entertaining possible explanations or solutions, and developing working hypotheses. This activity is like a "brainstorming" phase with evaluation suspended while explanations or solutions are written on a flipchart or chalkboard. Your group will need to formulate learning goals, outlining what further information is needed, and how this information can best be obtained.

Phase 3. The above list should inform your group in what to do in order to solve the problem. In this phase your group will discuss, evaluate, and organize hypotheses and tentative hypotheses. Your group will make a "What should we do?" list that formulates keeps track of such issues as what resources to consult, people to interview, articles to read, and what specific actions team members need to perform. It is in this phase that your group will identify and allocate learning tasks, develop study plans to discover needed information. You will be gathering information from the classroom, resource readings, texts, library sources, videos, and from external experts on the subject. As new information is acquired, your group will need to meet to analyze and evaluate it for its reliability and usefulness in applying it to the problem.

In short, you will be spending a great deal of time discussing the problem, generating hypotheses, identifying relevant facts, searching for information, and defining their own learning issues. Unlike traditional and standard classes, learning objectives are not stated up front. Rather, you and members of your group will be responsible for generating your own learning issues or objectives based on your group's analysis of the problem.

All during this process, as a student, you will be actively defining and constructing potential solutions. As an instructor, my role is primarily to model, guide, coach--to support you and your team through the learning and assessment process.

The majority of class time will be devoted to working in self-directed, PBL small group tutorials. A portion of class time will be allocated to "Resource Sessions," which may include simulations, case studies, and brief discussions to further explore concepts and issues which arise out of the PBL projects.
