Determined whether 11 third-grade children, differing in cognitive processing capacity, solve addition and subtraction word problems differently. Results, among others, show that children who differ in cognitive processing capacity also differ in strategies they use to solve the same verbal problems and differ in their success in finding correct…

Thirty concepts from the areas of sets, division, and expressing relationships were studied with twelve tasks dealing with naming or selecting attributes or concepts involved. A factor analysis indicated that all concepts were measures of a single functional relationship and that all tasks measure a single underlying trait. (LS)

To help the reader understand the scope and diversity of the Wisconsin R & D Center's research effort in mathematics, four perspectives are presented: (1) the Center's approach to research, development, and practice; (2) the origins of the current research effort; (3) a description of current research; and (4) a projection for future research.

Described is a method to assist developers of mathematics programs to make formative evaluations. The method involves periodic achievement testing via item sampling. Details of item construction, periodic testing, and profile construction are given in a discussion of how this method was applied to modify a sixth-grade mathematics program. (JP)

Self-instructional booklets containing the advance organizer, cognitive set, and post organizer varying according to experimental treatment were randomly assigned within nine Algebra 2 classes. Results showed a significant interaction between advance and post organizers: either one used separately facilitated learning and retention, but when used…

Tests were given after instruction in probability and four weeks later to 25 sixth graders. Correlation between achievement scores for each student was .78. Retention ratios for individuals, total tests, each objective, and each item indicated high initial performance may contribute to high retention. (Author/DT)

An exploratory study involving three days of brief instruction in a process-by-attribute approach. Significant performance gains were recorded. (MM)

A critique is given of the use of an efficiency ratio to reexamine the data of the International Study of Achievement in Mathematics. A reply to this and an earlier critique of the analysis is included. (JG)

Examined is the discrepancy between the initial press release of the IEA International Study of Mathematics Achievement and the full report. (CT)

Responds to Apple's article by making seven points that discuss (1) the Standards as a vision; (2) changes in mathematics; (3) changes in how one learns; (4) democratic citizenship; (5) costs; (6) quality of examples; and (7) working conditions for the teacher. (MDH)
