One important finding from recent research on multiplication word problems is that children's performances are strongly affected by the nature of the multiplier (whether it is an integer, decimal larger than 1 or a decimal smaller than 1). On the other hand, the size of the multiplicand has little or no effect on problem difficulty. The aim of the…

This research was concerned with the clarification of the role that the external representation process (e.g. drawing) plays in children's solving of complex arithmetic problems. Fourteen children in the 10- to 12-year-old age range were asked to represent and solve five complex arithmetic problems (three with temporal organization of data, two…

The purpose of this project was to evaluate the effectiveness of an interactive Level 1 videodisc program called "Mastering Fractions." The evaluation was conducted in two parts. Part 1 was a controlled study that compared the Mastering Fractions program to a more traditional fractions curriculum while controlling for any novelty effect of the…

Microcomputer-based laboratories (MBL), the use of microcomputers for student-directed data acquisition and analysis, represents a promising new development in science laboratory instruction. This descriptive study determined the impact of MBLs on middle school students' understanding of graphs of distance and velocity. The study was based on the…

This is a part of the Manitoba Mathematics Assessment Program 1987. Actual testing material and the manual for grade six are provided. The test (90 items) requires two 45-minute sessions. The manual describes general testing instructions, administration, scoring method and key, and format for recording the final test scores. (YP)

Longitudinally examines the stability of the association between maternal behavior and preschool children's cognitive abilities. Outcome measures included both school readiness (assessed at ages five and six) and achievement on mathematics and vocabulary subtests of the Iowa Tests of Basic Skills at grade six. (Author/RH)

The purpose of this study was to determine the effects of using calculators on the mathematical achievement and attitude of low-income sixth-grade students when they were taught problem solving. Thirty-five sixth-grade students in two intact classes were assigned to two treatment groups. The experimental group was taught problem solving using…

This study examined computerized classwide applications of curriculum-based measurement (CBM) to improve teachers' math planning within large group instructional settings, using a mathematics operations curriculum in 10 sixth grade classes. Preliminary findings suggest CBM increases teachers' abilities to incorporate students with disabilities…

To gather longitudinal student achievement data from schools utilizing the four-day week, Iowa Tests of Basic Skills (ITBS) grade equivalent scores were obtained in 1984 from five rural Colorado school districts for four consecutive years--two years prior to and two years following the districts' change to the shortened week. A first analysis…
