Applying
the Results
The
information presented in Algebra Textbooks: A Standards-Based
Evaluation is intended to assist teachers, adoption committees,
and others in making initial decisions about textbooks and narrowing
the field to a more manageable number of candidates for closer review.
For those already using one of the textbook series, the summary
reports can also help point to overall strengths or weaknesses that
might have implications for supplementing the material for some
or all students, or for staff development needed to help teachers
use the textbooks effectively.
Eight
data sets are included for each of the 12 textbook series: (1) Background
Information, (2) Content Analysis, (3) Instructional Analysis, (4)
Instructional Ratings, (5) Graphs, (6) Rater Consistency, (7) Typical
Sightings, and (8) Sightings by Idea Set. Once educators have narrowed
their choices to three or four textbook series, the data sets can
provide valuable information that will help narrow the field even
more.
