Closed Corpus Approach

• Mentor controls/decides resources available to Learner

• Mentor focuses Learner effort/attention

• Like learning from a good textbook

• Traditional CAL is largely closed corpus.
  Includes interaction and assessment based on an individual's responses and history.

• CDs (closed delivery?) work well here.

• Web becomes purely an access mechanism for predefined corpus

  • Extensions of books and lecture materials

  • Very important, early, easy application:
    Use new media to replicate and to extend a well-chosen subset of earlier experiences.

• Assessment (a cornerstone of good CAL) might appear harder with the Web than with traditional CAL
