EDTEC 700 DM: Week 2

  1. 1. EDTEC 700 Using Problem-Based Learning to Enhance Decision-Making Skills: Week 2 Bernie Dodge, PhD San Diego State University
  2. 2. Progress Report <ul><li>What problem have you proposed? </li></ul><ul><li>Who are the learners? </li></ul><ul><li>What is the context? </li></ul><ul><li>What challenges do you anticipate? </li></ul>
  3. 3. Finding Problems to Learn from <ul><li>Start with outcomes </li></ul><ul><li>Ask yourself: where is this skill or knowledge applied in the world? </li></ul><ul><li>Find or fabricate a situation in which something is not optimal that requires that skill/knowledge. </li></ul>
  4. 4. Steps in PBL <ul><li>Determine whether a problem exists. </li></ul><ul><li>Create an exact statement of the problem. </li></ul><ul><li>Identify information needed to understand the problem. </li></ul><ul><li>Gather information and organize it. </li></ul><ul><li>Generate possible solutions. </li></ul><ul><li>Decide on a solution. </li></ul><ul><li>Present the solution. </li></ul><ul><li>Reflect on & evaluate. </li></ul>Finkle and Torp, 1995
  5. 5. Pareto Analysis <ul><li>Useful at the earliest stages of the PBL process </li></ul><ul><li>Purpose: decide which aspects of the problem to work on first </li></ul><ul><li>Based on the Pareto Principle of 80-20. </li></ul>
  6. 6. Exercise 3 <ul><li>Based on a true story. </li></ul><ul><li>Help Ms. X decide what aspects of her teaching she should work on. </li></ul>http://edweb.sdsu.edu/courses/edtec700/DM/exercise3.htm
  7. 7. 6 Thinking Hats
  8. 8. Blue Hat <ul><li>Hat worn by people chairing meetings. </li></ul><ul><li>Pays attention to the process and directs the other hats to pitch in </li></ul>
  9. 9. White Hat <ul><li>focus on the data available. </li></ul><ul><li>look at the information you have, and see </li></ul><ul><li>look for gaps in your knowledge, and either try to fill them or take account of them. </li></ul>
  10. 10. Green Hat <ul><li>stands for creativity. This is where you can develop creative solutions to a problem. </li></ul><ul><li>freewheeling way of thinking, in which there is little criticism of ideas. </li></ul>
  11. 11. Red Hat <ul><li>looks at problems using intuition, gut reaction, and emotion. </li></ul><ul><li>tries to think how other people will react emotionally. </li></ul><ul><li>tries to understand the responses of people who do not fully know your reasoning. </li></ul>
  12. 12. Yellow Hat <ul><li>the optimistic viewpoint that helps you to see all the benefits of the decision and the value in it. </li></ul><ul><li>helps you to keep going when everything looks gloomy and difficult. </li></ul>
  13. 13. Black Hat <ul><li>looks at all the bad points of the decision. </li></ul><ul><li>tries to see why it might not work. </li></ul><ul><li>highlights the weak points in a plan. </li></ul>
  14. 14. Exercise 4 <ul><li>Pick a problem or decision of personal interest to you. </li></ul><ul><li>Use the worksheet to think about your problem in 6 different ways and develop a fresh set of insights. </li></ul>http://edweb.sdsu.edu/courses/edtec700/DM/exercise4.htm
  15. 15. Decision Trees <ul><li>Most complex of the 5 we’ve covered </li></ul><ul><li>Appropriate when there are a sequence of decisions to be made </li></ul><ul><li>Leads to quantifiable end points to guide decisions </li></ul>
  16. 16. Decision Tree Steps <ul><li>Pick a starting point </li></ul><ul><li>Identify two or three choices that could be made </li></ul><ul><li>For each choice, pick 2-3 followup choices that one could make </li></ul><ul><li>Carry through as far as feasible </li></ul>
  17. 17. Decision Tree Steps <ul><li>After the final set of choices… </li></ul><ul><li>Identify the values of the final outcomes in terms of whatever variable is important to you </li></ul><ul><li>Identify the probabilities of each outcome </li></ul><ul><li>Multiply the probabilities of each by the value of the outcome. </li></ul>
  18. 18. Exercise 5 <ul><li>Use decision tree analysis to break a situation down into choices, consequences and probabilities. </li></ul>http://edweb.sdsu.edu/courses/edtec700/DM/exercise5.htm
  19. 19. PBL & the Digital Divide <ul><li>The One Laptop per Child Project is bringing technology to villages in developing countries. </li></ul><ul><li>Constructivism and PBL underlie the project’s goals. </li></ul>http:// www.laptop.org /
