A taxonomic matrix classification was used to assess the curricular validity of the Stanford Achievement Tests for the mathematics textbooks used in a school district's fifth and sixth grades. Rasch item difficulty was also examined. Results indicated only small differences between textbooks. (GDC)

This investigation attempts to determine if the congruity in textbook-test content varies as a function of different styles of textbook use. Across all standardized tests, instructional validity of the five styles of textbook use was far lower for the management-by-objectives model than for any other styles. (Author/PN)

The purpose of this study was to determine if the Saxon Mathematics series produced gains in math achievement of elementary school students. Mathematics achievement was assessed for 190 students in the Southside School District No. 3, Batesville, Arkansas, using the Stanford Achievement Test Eighth Edition during April 1992 and April 1993. There…

A taxonomy was developed for classifying instructional materials in fourth grade mathematics, as well as the content of actual classroom instruction and of achievement tests. The taxonomy is defined by the intersection of three factors and results in 468 cells: (1) mode of presentation (for example, use of graphs, tables, story problems)--3…
