  • 1. A Practical Method for Courseware Evaluation Aldo de Moor CommunitySense PragWeb 2007
  • 2. The Pragmatic Web of what? Communal effective use of Information Functionalities
  • 3. Courseware and the Pragmatic Web Pragmatic Web = context How to evaluate web functionalities in their context of use? Courseware provides an interesting domain technological environments consisting of multiple functionality components, together offering a complete system of info/comm services required for supporting course needs Functionality evaluation needed Too much (costly) functionality Gaps between required and available functionality Conflicting functionality requirements
  • 4. Functionality Functionality A set of functions and their specified properties that satisfy stated or implied needs Levels of granularity Systems Courseware environments Tools Blackboard Modules Announcements Functions Post announcement
  • 5. A context model of courseware evaluation
  • 6. A practical courseware evaluation method Portfolio methods Scores weighed by infrastructure/architecture of organization. Bedell’s method for ICT investment selection Functionalities scored on both effectiveness and importance for the activities to be supported. Practical method Simplification of Bedell No higher-order analyses Actors (users in their roles) provide, interpret and decide upon scores Context: courseware evaluation: Actors: students, software manager Tool system level: module Two questions How well are course activities supported by various functionality components? To what extent are the functionality modules used?
  • 7. Scores Elements I(a) = importance of activity E.g. I(Information Collection) = 9 I(f,a) = importance of functionality f in supporting activity a E.g. I(Virtual Chat, Information Collection) = 4 Q(f,a) = quality of functionality in supporting an activity E.g. Q(File Transfer, Submission of Results) = 8
  • 8. Activity and functionality scores Activity scores Σ I(fi,a) * Q(fi,a), for all functionalities 1..i. Usefulness of the combined technologies for a particular activity Relevant for technology users (lectures, students) Functionality scores Σ I(aj) * I(f,aj) * Q(f,aj), for all activities 1..j Usefulness of a particular functionality component for the combined activities Relevant for technology developers/maintainers
  • 9. Experiment: evaluating group assignment functionality Two courseware tools: Blackboard, CourseFlow Goal: making group assignments Four activities, 11 functionality modules Actors: 2nd year Information Management students, software manager 2002: 62 students, 16 groups 2003: 46 students, 12 groups Questions Quality of tools for various group assignment activities? Usefulness of various functionality modules?

  • 14. Conclusion Practical method, shown to be useful for initial courseware functionality selection Context-bound, in toto, ex-post evaluation Simple measures useful for quickscan and discussion purposes Open source can perform just as well “E-learning organization”: continuous evolution / evaluation needed
