This study compared the effects of three different feedback formats provided to sixth grade mathematics students within a web-based online learning platform, ASSISTments. A sample of 196 students were randomly assigned to one of three conditions: (1) text-based feedback; (2) image-based feedback; and (3) correctness only feedback. Regardless of…

This article describes a follow-up analysis of findings from a randomized study that tested the efficacy of a blended version of Enhanced Anchored Instruction (EAI) designed to improve both the computation and problem-solving performances of middle school students with disabilities. The goals of the secondary analysis were to track overall error…

This study examines the effect varying models have on student understanding of fractions. The study addressed the question of what students know and understand about fractional concepts through the use of discrete and continuous models. A sample of 54 students in kindergarten and 3rd grade were given an interview pretest, participated in…

This article reports results from a study investigating the impact of a sustained, comprehensive early algebra intervention in third grade. Participants included 106 students; 39 received the early algebra intervention, and 67 received their district's regularly planned mathematics instruction. We share and discuss students' responses to a written…

The effectiveness of different concrete and pictorial models on students' understanding of the part-whole construct for fractions was investigated. Using interview data from fourth and fifth grade students from three different districts that adopted the "Mathematics Trailblazers" series, authors identified strengths and limitations of models used.…

Four hundred and three 3rd- and 5th-grade Chinese students took the Multiplication Estimation Test or participated in the interview on it, designed to assess their computational estimation performance on whole-number multiplication. Students perform better when tasks are presented visually than orally. Third graders tend to use rounding based…

This study determined the effect of Cuisenaire Rods' approach on some Nigeria primary pupils' achievement in decimal fractions. Three hypotheses guided the study. A total of 200 Primary six pupils (that is, 6th grade) from randomly selected schools in Makurdi metropolis of Benue State of Nigeria served as the sample for the study. A Mathematics…

This study investigated the role of different modes of representation, i.e., verbal description, decorative pictures, informational pictures and number line, in solving additive change problems. Data were collected from 1447 students in Grades 1, 2, and 3. Structural equations modelling affirmed the existence of four first-order…

This study identified differences in elementary school students' performance of arithmetic tasks using paper and pencil and computer-assisted instruction. Many were found to perform more poorly using the computer, while others showed the opposite tendency. These findings challenge the validity of decisions made by the computer-based management…

Describes two studies conducted in The Netherlands that compared two modes of off-air videotape use of educational television programs on mental arithmetic for elementary students. Active use of the videotapes with interruptions for interactive teaching are compared with passive, uninterrupted viewing, and implications for the design of…

An investigation of how secondary students coped when taught binary arithmetic through a computer assisted instruction program used four treatment groups: learner control, learner control with advice; random program control, and adaptive program control. The random group performed less well, but no differences were found between learner and…

Description of a microcomputer-based instructional strategy used to adapt computer assisted instruction (CAI) to individual learners' needs highlights its use with elementary school arithmetic classes to solve work problems. Experiments with a control group that received conventional problems are described, and applications for undergraduate…

Discusses an adaptive diagnostic test used as part of an instructional program in signed-number arithmetic on the PLATO system. Findings indicated that differences in prior and subsequent instructional methods affected the learning of more advanced materials and produced lower achievement scores on posttests. Thirty-two references are listed. (MER)
