  1. Designing Assignments to Wrap-Up PBL Problems Courtesy of Hal White Workshop at Marymount University May 9, 2003

  2. PBL Problem Assignments Why consider a PBL assignment separate from a PBL problem? Isn’t the problem the assignment? You have drafted a PBL problem for your course. It addresses important concepts in a substantive context. Students will learn, understand, and remember.

  3. Why Assignments? ...Accountability What does it mean when a student says,I understand?.... Does it mean the same thing to that studentthat it does to another student or to you, the professor?..… How can students demonstrate their understanding to you and others?

  4. …and Closure PBL problems are typically open-ended. Student within a single group often pursue different learning issues. Students frequently have difficulty knowing what the instructor thinks is important. Assignments focus on central issues and bring closure to PBL problems.

  5. Activity for Everybody Consider some of the PBL problems you have encountered to date. What are some examples of student assignments from these problems? You may contribute examples from other sources as well.

  6. Activity for Groups Based on these examples and others, generate a list of considerations that would be appropriate when designing an appropriate assignment to wrap-up a PBL problem.

  7. Considerations for PBL Assignments • Individual or group response? • Course/problem content objectives? • General education and PBL goals? • Graded or not? • Difficulty? (Bloom’s Taxonomy) • Interest level for students? • Form of the response?

  8. PBL Problem Assignments Written assignments Write a 2-3 page paper on a learning issue you researched. Critique this recent magazine article in terms of the problem you have just finished. Transform an experiment described in this article into a laboratory exercise appropriate for undergraduates. Who is the audience in each case?

  9. PBL Problem Assignments Written assignments Write a letter to the editor of your local newspaper on this issue. Compose a 200 word abstract for the article you have just read based on the Guidelines for Authors in JBC. Research a topic related to the course and write a PBL problem for this course based on that topic. Who is the audience in each case?

  10. PBL Problem Assignments Written and visual assignment Create a website appropriate for high school students on this topic.

  11. PBL Problem Assignments Written, oral, and visual assignments Prepare a case for your position and present it to the class as a debate. Prepare a 15-minute informative talk on this topic using PowerPoint slides.

  12. PBL Problem Assignments Visual Assignment Prepare a concept map incorporating the major issues related to this problem.

  13. Concept Mapping: An Instructional Tool to Organize Content and Assess Student Learning • What is a concept map? • What are the features of a concept map? • How do you construct a concept map? • How do you use concept maps?

  14. What is a Concept Map “a general method with which one can clarify and describe people’s ideas about some topic in a graphical form” Katsumoto 1997 a pictorial representation that shows the relationships between and among a connected set of concepts and ideas

  15. Purposes for Concept Mapping • Generate ideas (brainstorming) • Design complex structures (long texts, web-sites) • Communicate complex ideas • Aid learning by explicitly integrating new and old knowledge • Assess understanding or diagnose misunderstanding

  16. Short Assignment Arrange the following three terms and connect them with arrows and linking phrases Bacteria Pneumonia Antibiotics

  18. CONCEPT MAP OF CONCEPT MAPPING Propositions Ideas Linear Text Study & Revision Aid may develop related by relate alternative to Concepts Metacognition used as awareness of Classroom Teachers consists of Concept Maps Learning Processes suitable for used as of Research & Assessment Tool may increase to assess increasing Learning Learning Effectiveness reveals may address Misconceptions Enjoyment improving Affective Objectives such as increasing Feelings & Values to do with Motivation Interest Adapted from K. S. Taber (1994) Physics Education 29(5) 276-281

  19. Where does Concept Mapping Fit Into PBL? Individual Accountability depends on Problem-Based Learning Cooperative Learning Groups uses working on need reflected in expected by has tied to Group Accountability Problems Faculty Students Society Grades Learning Goals that are Content Objectives including Process Skills based on Real World Open-ended Complex achieved with Examinations Group Assignments reflected in including Peer Evaluation such as to promote Writing Assignments seen in should limit Individual Learning that address and minimize Divide and Conquer Strategies Concept Mapping Academic Dishonesty such as that display Scholarly Synthesis Organization Disciplinary Rhetoric Student Voice that incorporate Leadership Communication Conflict Management Sharing Information Accepting Information Peer Evaluation that access Term Papers PBL Problems Case Studies Revision Peer Feedback Library & Internet Resources informed by

  22. Designing Assignments to Wrap-up PBL Problems Assignments are an integral part of PBL problems. PBL assignments address issues of accountability and closure. In writing PBL problems, consider the assignment carefully. PBL assignments can have many forms.
