Does the material provide multiple and varied phenomena to support the key ideas?


Indicators of meeting the criterion

  1. Phenomena are useful in making the key ideas real.
  2. Phenomena are explicitly linked to the relevant key ideas. [6],[7]

Rating Scheme
Excellent: The material provides a sufficient number and variety of phenomena that meet indicators 1 and 2.
Satisfactory: The material provides some phenomena that meet indicators 1 and 2.
Poor: The material provides, at best, one phenomenon that meets indicators 1 and 2.

If the benchmark for which the material is analyzed includes several ideas, the reviewers should proceed as follows:

  1. Identify the ideas for which there is a content match.
  2. Score the treatment of each idea that results from step a. The overall score for this criterion will be the average of the scores for each idea.
