Problem Based Learning

1. Problem Based Learning Nancy Allen, Ph.D. College of Education Office of Faculty Development Qatar University

2. Session Objectives • Explain the theory and practice of Project Based Learning (PBL). • Engage faculty in considering PBL as an instructional strategy. • Discuss how to plan and conduct effective PBL .

3. Learning Outcomes • Give an operational definition of Problem Based Learning (PBL). • Describe how to construct a PBL experience. • Give examples of how PBL can be used in instruction. • Evaluate PBL designs. • Construct a PBL experience for a course you teach.

4. I have a problem. I don’t know you.

5. Can you help me? • First: Organize yourself into working groups. • Group Manager • Recorder • Reporter • Resource Manager

6. As a group… • First, clarify the question.

7. What is the problem?

8. What constitutes successful completion? • In one hour’s time, your group will present what you believe is an accurate and helpful profile of the participants in this workshop. • You will have a maximum of five (5) minutes to present. • Everyone in the group is expected to take part in the research and in the presentation.

9. As a group… • Decide what you know, what you need to know, and how you can find out.

10. What resources do you have? What resources do you need?

11. Knowledge and Skills

12. "The basic principle supporting the concept of PBL is older than formal education itself; namely, learning is initiated by a posed problem, query, or puzzle that the learner wants to solve" (Duch, Groh, & Allen, 2001).  

13. Once Kind of Active Learning • PBL overlaps with other active learning models such as groupwork and case studies, but is distinguished by the focus on having students delineate, research, and solve a realistic problem.

14. Why Use Problem-Based Learning • PBL better prepares students to apply their learning to real-world situations. • PBL enables students to become producers, rather than consumers, of knowledge. • PBL can help students develop communication, reasoning and critical thinking skills. • Research review

15. Review of research • Learning in a PBL format may initially reduce levels of learning (this may be due to the difficulty in determining what students learned using traditional competence measures), but may foster, over periods up to several years, increased retention of knowledge; • Some preliminary evidence suggests that PBL curricula may enhance both transfer of concepts to new problems and integration of basic science concepts into clinical problems; • PBL enhances intrinsic interest in the subject matter; and • PBL appears to enhance self-directed learning skills (metacognition), and this enhancement may be maintained (Norman & Schmidt, 1992, in Evensen & Hmelo, 2000).

16. Goals of PBL: • PBL is used to engage students in learning. This is based on several theories in cognitive theory. Two prominent ones are that students work on problems perceived as meaningful or relevant and that people try to fill in the gaps when presented with a situation they do not readily understand.

17. Teachers present students with a problem set, then student work-groups analyze the problem, research, discuss, analyze, and produce tentative explanations, solutions, or recommendations. It is essential to PBL that students do not possess sufficient prior knowledge to address the problem. In the initial discussion, students develop a set of questions that need to be addressed. These questions then become the objectives for students' learning.

18. Norman and Schmidt (1992) state there are three roles for PBL. • The first is the acquisition of factual knowledge, the second is the mastery of general principles or concepts that can be transferred to solve similar problems, and third, the acquisition of prior examples that can be used in future problem solving situations of a similar nature.

19. Acquiring Factual Knowledge: • Activation of prior knowledge facilitates the subsequent processing of new information. Small group discussion helps activate prior knowledge.

20. Elaboration of knowledge at the time of learning enhances subsequent retrieval.Matching context facilitates recall. This means that retrieval of information is facilitated by retrieving under the same conditions in which the information was learned.

21. Transfer of Principles and Concepts • To insure successful transfer, students need to get the problem cold. Any advance organizer that identifies the problem in advance appears to detract from the PBL process. It appears important that students learn and acquire concepts while wrestling with the problem.

22. Activation of prior knowledge, taking place while a problem is initially discussed, may have a stage-setting function for new knowledge that facilitates students processing it.

23. How does problem-based learning work?

24. What instructors do: • Develop real-world, complex and open-ended problems such as might be faced in the workplace or daily life. • Act as facilitators, making sure students are staying on track and finding the resources they need. • Raise questions to student groups that deepen the connections they make among concepts. • Strike a balance between providing direct guidance and encouraging self-directed learning.

25. What students do: • Address the problem, identifying what they need to learn in order to develop a solution and where to look for appropriate learning resources. • Collaborate to gather resources, share and synthesize their findings, and pose questions to guide further learning tasks for the group. • Generate and defend plans or solutions based on their research.

26. How do I get started with PBL?

27. Develop problems that: • Capture students’ interest by relating to real-world issues. • Draw on students’ previous learning and experience. • Integrate content objectives with problem-solving skills. • Require a cooperative, multi-staged method to solve. • Necessitate that students do some independent research to gather all information relevant to the problem.

28. Examples of Problems • Biology: Students examine the health claims of a widely advertised dietary supplement • Art History: Students weigh competing evidence to determine whether a museum acquisition is real or forged • Environmental Science: Students develop a preservation plan for a local forest Center for Instructional Development and Research (2004).

29. Design assessment tools that: • Account for process (e.g. research, collaboration) as well as content skills. • Are closely tied to course learning objectives. • Balance group performance.

30. What kinds of classes can PBL be used in? • PBL has successfully been used in disciplines ranging from engineering to art history.

31. When adapting PBL for your course, consider the following: • An entire course can be PBL based, or PBL can be used for part of a given unit. • Depending on your learning goals, it is possible to design problems with a narrow range of correct solutions (such as medical diagnoses) or with a wider range of creative possibilities (such as architectural designs). • Though usually based in groupwork, PBL can also have individualized components, provided that students are required to come together to discuss their findings.

32. Problem-Based Learning: The Process • Identify objectives/learning outcomes to be addressed. • Decide what activities/artifacts will demonstrate mastery. Identify/design assessment instruments. • Decide how much time you have/can give to the activity and set the time apart. • Find/design the problem situation. • Identify and obtain necessary student resources. • Form groups. • Begin project. • Constantly monitor and coach.

33. Problem-Based Learning: The Process • Present the problem situation. • List what is known. • Develop a problem statement. • List what is needed. • List possible actions, recommendations, solutions, or hypotheses. • Present and support the solution. Institute for Transforming Undergraduate Education (2005).

34. PBL Planning Guide • Resources Needed • Support materials for students: • Problem situation statement • Supportive documents • Web track • Expert list • Print-based resources • Opportunities for research • Assessment Instruments • Presentation Resources Institute for Transforming Undergraduate Education (2005).

35. The Unit in Action Remember: The Goals of PBL include: • Course objectives and learning outcomes • General research skills • Higher level thinking • Collaborative work skills Institute for Transforming Undergraduate Education (2005).

36. The Unit in Action Present the problem situation to students. They will: • List what is known. • Develop a problem statement. • List what is needed to solve the problem. • List possible actions, recommendations, solutions, or hypotheses. • Present and support the solution. Institute for Transforming Undergraduate Education (2005).

37. 1. Present the problem statement. • Introduce an "ill-structured" problem or scenario to students. They should not have enough prior knowledge to solve the problem. This simply means they will have to gather necessary information or learn new concepts, principles, or skills as they engage in the problem-solving process. Institute for Transforming Undergraduate Education (2005).

38. 2. List what is known. • Student groups list what they know about the scenario. This information is kept under the heading: "What do we know?" This may include data from the situation as well as information based on prior knowledge. Institute for Transforming Undergraduate Education (2005).

39. 3. Develop a problem statement. • A problem statement should come from the students' analysis of what they know. The problem statement will probably have to be refined as new information is discovered and brought to bear on the situation. Typical problem statements may be based on discrepant events, incongruities, anomalies, or stated needs of a client. Institute for Transforming Undergraduate Education (2005).

40. 4. List what is needed. • Presented with a problem, students will need to find information to fill in missing gaps. A second list is prepared under the heading: "What do we need to know?" These questions will guide searches that may take place on-line, in the library, and in other out-of-class searches. Institute for Transforming Undergraduate Education (2005).

41. 5. List possible actions, recommendations, solutions, or hypotheses. • Under the heading: "What should we do?" students list actions to be taken (e.g., questioning an expert), and formulate and test tentative hypotheses. Institute for Transforming Undergraduate Education (2005).

42. 6. Present and support the solution. • As part of closure, teachers may require students to communicate, orally and/or in writing, their findings and recommendations. The product should include the problem statement, questions, data gathered, analysis of data, and support for solutions or recommendations based on the data analysis. Institute for Transforming Undergraduate Education (2005).

43. 6. Present and support the solution. • Students are encouraged to share their findings on-line with teachers and students in other schools, within the district, region, state, nation, or internationally. Teachers will find that students pay more attention to quality when they have to present or show their written products to students in other schools. Institute for Transforming Undergraduate Education (2005).

48. Planning Guide • Problem situations • As you explore the civilizations of the ancient world, you will try to answer questions about how people lived thousands of years ago. It may be hard to answer every question because sometimes there is not enough evidence to support a conclusion. Historians may also look at the same evidence in different ways. Sometimes the experts have to change their answers as new artifacts are discovered.In this activity, you will study the structures of Mesopotamia, Egypt, India, and China. As you learn about these wonders of the ancient world, remember that there are many different ideas about why and how they were built.Some people think that ancient people learned how to build these awesome monuments by aliens from outer space who were more advanced than earthlings. Others believe that one culture may have borrowed from other people on earth who already knew how to build. Still others think that people in these cultures created the monuments totally on their own without any outside contact.
