This study assessed if students with and without disabilities used calculators (fourfunction, scientific, or graphing) to solve mathematics assessment problems and whether using calculators improved their performance. Participants were sixth and seventh-grade students educated with either National Science Foundation (NSF)-funded or traditional…

For an entire school year, 24 seventh-grade classes were taught problem-solving strategies; in 14 of these classes the instruction was supplemented by calculators. Mixed findings resulted for both problem solving and calculator use. (MNS)

A problem-solving program supplemented by calculators in one treatment group was conducted in 63 grade 7 classes with about 1350 students. Teachers were provided with problems correlated with textbooks, and instruction for teaching problem-solving strategies. School districts provided calculators and problem-solving materials. Pretest scores…

This report examines the most recent middle school data from the National Assessment of Educational Progress (NAEP) to investigate how selected dimensions of instructional practice are related to higher-order learning of middle-grade students. In particular, the paper: (1) outlines the theoretical basis for prescribing middle level instructional…

This report brings together in a single source observations and materials of instructional importance in calculator explorations with seventh-grade students from 1976 through 1978. Students used algebraic-logic calculators with no operational hierarchies. At the end of the school year, students were introduced to reverse Polish notation-based…

Students in three grade 7 classes, a grade 6 class and a split grade 5/6 class were provided with calculators for use in their mathematics classes for a period of eight weeks. For the posttest on problem solving the 116 students were randomly assigned to the group using calculators on the posttest or to the group using only paper and pencil. In a…

This article addresses some important issues in mathematics instruction at the middle and secondary levels, including the structuring of a district's mathematics program; the choice of textbooks and use of calculators in the classroom; the need for more rigorous lesson planning practices; and the dangers of teaching to standardized tests rather…

The National Science Foundation funded Calculators and Mathematics Project, Los Angeles (CAMP-LA) developed curriculum materials focused solely on the use of calculators. The project was developed in three stages. The first stage studied the mathematics curriculums from different states and identified topics that are not included but should be if…
