Rating Scheme
Excellent: The
material includes a sufficient number and variety
of representations that meet indicators 13
and none of the representations included in the material
are inaccurate. (In order to judge whether there
is a sufficient number and variety of representations,
reviewers should first consider which key ideas require
representations and then decide whether these are
adequately represented. However, reviewers are not
expected to evaluate and rate each idea separately
and average the scores.)
Satisfactory: The
material includes some representations that meet
indicators 13 and few (if any) of the representations
included in the material are inaccurate. (In some
cases, including one accurate and comprehensible
representation for a specific idea may be sufficient
for a material to receive a "satisfactory" rating.
However, most of the key ideas must be adequately
represented.)
Poor: Even
though the material includes a few representations
that meet indicators 13, few or none of the
key ideas are adequately represented.
