E-Learning Patterns as an analysis framwork to foster excellent e-learning

  1. 1. Patterns as an analysis framework to document and foster excellent e-learning designs Christian Kohls Knowledge Media Research Center
  2. 2. Fitness between context and form <ul><li>„ It is based on the idea that every design problem begins with an effort to achieve fitness between two entities: the form in question and its context. The form is the solution to the problem; the context defines the problem.“ (Alexander, 1964) </li></ul>
  3. 3. My key issues <ul><li>Fitness : Does a solution fit to the context and its problem? </li></ul><ul><li>Analysis : Describing good (fitting) practices as patterns </li></ul><ul><li>Reliability : Can we trust the patterns? </li></ul><ul><li>Mining : How do patterns emerge? </li></ul><ul><li>Wholeness : What makes a good pattern? </li></ul>
  4. 4. Context for educational settings <ul><li>Organizational form (school, university, professional training) </li></ul><ul><li>Domain (Science, Art, Economics,…) </li></ul><ul><li>Political issues (budgets, fundings, evaluation) </li></ul><ul><li>Skills of teachers and students </li></ul><ul><li>Pre-existing knowledge </li></ul><ul><li>Complexity of the content </li></ul><ul><li>Teaching goals, student‘s goals </li></ul><ul><li>Number of participants </li></ul><ul><li>Schedules, amount of time </li></ul><ul><li>Aattitudes </li></ul><ul><li>Available equipment and resources </li></ul><ul><li>History and traditions </li></ul>Describes a situation, environment or setting
  5. 5. Problems and forces <ul><li>Cognitive limits </li></ul><ul><li>Concentration </li></ul><ul><li>Handling many students </li></ul><ul><li>Doing research and teaching </li></ul><ul><li>Personal conflicts </li></ul><ul><li>Struggling with many lessons </li></ul><ul><li>Freedom and guidance </li></ul><ul><li>Skills need to checked </li></ul><ul><li>Pressure before exams </li></ul><ul><li>Fair ratings </li></ul><ul><li>Cheating </li></ul><ul><li>Plagiarism saves time </li></ul><ul><li>… </li></ul>A conflict of forces that raise in the context.
  6. 6. Solution <ul><li>The essential form that fits and resolves the forces. </li></ul><ul><li>Solution Details </li></ul><ul><li>Benefits </li></ul><ul><li>Liabilities </li></ul><ul><li>Drawbacks </li></ul><ul><li>Consequences </li></ul><ul><li>Obstacles </li></ul><ul><li>Variations </li></ul><ul><li>Preparation </li></ul><ul><li>Implementation </li></ul><ul><li>Wrap-up </li></ul><ul><li>Tools </li></ul><ul><li>… </li></ul>
  7. 7. But how do we find the solution? <ul><li>Context and forces are not fully known </li></ul><ul><li>Not any form is a solution – most forms are not. </li></ul><ul><li>There is causality for fitting forms </li></ul><ul><li>Evidence: The Rule of Three </li></ul><ul><li>Is it the best solution? </li></ul><ul><li>Is it the only solution? </li></ul><ul><li>Will it last? </li></ul><ul><li>Patterns emerge… </li></ul>
  8. 8. The pattern definiton. <ul><li>„ Each pattern describes a problem which occurs over and over again in our environment , and then describes the core of the solution to that problem , in such a way that you can use this solution a million times over, without ever doing it the same way twice.“ (Alexander, 1977) </li></ul>
  9. 9. Decomposition of structure The sum is more than its parts. Alexander, 1964
  10. 10. Decomposition of structure
  11. 11. Wholeness <ul><li>Every variables has to fit </li></ul><ul><li>Sub patterns have to fit to each other </li></ul><ul><li>Fuzzy bounds with different ranges of tolerance </li></ul><ul><li>Closure: Maximal closure of invariance </li></ul>
  12. 12. Summary & Discussion <ul><li>Fitness: Does a solution fit to the context and its problem? </li></ul><ul><li>Analysis: Describing good practices as patterns </li></ul><ul><li>Reliability: Can we trust the patterns? </li></ul><ul><li>Mining: How do patterns emerge? </li></ul><ul><li>Wholeness: What makes a good pattern? </li></ul>
