This study compared the effectiveness of 3 procedures for teaching 62 elementary students with learning disabilities to identify the correct algorithm in solving addition and subtraction word problems. The group receiving strategy teaching and sequencing practice problems and the group receiving strategy teaching only scored higher than…

The purpose of this study was to assess the effects of schema-broadening instruction (SBI), with and without explicit instruction in strategies for tackling the complexities involved in real-life (RL) math problems, on the math problem solving of third-grade students. Teachers (n = 30) were assigned randomly to 3 16-week conditions: control, SBI,…

Mathematical problem solving is a transfer challenge requiring children to develop schemas for recognizing novel problems as belonging to familiar problem types for which they know solutions. Schema-based transfer instruction (SBTI) explicitly teaches transfer features that change problems in superficial ways to make them appear novel even though…

In 2 experiments with 74 high school students, subjects studied worked examples while learning how to translate English expressions into algebraic equations. Those using worked examples outperformed the control group on posttests, made fewer errors, completed work more rapidly, and required less assistance from the teacher. (SLD)

This study examined effects of contextualized math instruction on problem-solving performance of 17 middle school remedial students and 49 average-achieving prealgebra students. Results showed that both remedial and average students receiving contextualized-problem instruction outperformed comparison groups receiving word-problem instruction.…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…

Examined the differential effects of two instructional strategies (explicit schema-based and traditional-based) on the acquisition, maintenance, and generalization of mathematical word problem solving among elementary students at risk or with mild disabilities. Pretesting and posttesting indicated that both groups' performance increased from…

Two experiments involving 90 primary and intermediate-grade students studied how the COPPERS computer-based mathematical learning environment advances children's understanding that multiplication problems have many different correct solutions. Factors affecting learning and theoretical implications are discussed in terms of scaffolding learning.…

This study compared the effectiveness of a diagrammatic and a keyword method of teaching mathematics problem solving to 70 learning-disabled junior high school students. Results indicated no significant difference between problem-solving performance by students taught with different methods. Potential factors explaining inconsistencies between…

One hundred forty fourth graders were asked to solve proportion problems about juice-mixing situations both before and after an intervention that used a manipulative model or other materials in three experiments. Results indicate different approaches appear to be necessary to facilitate children's proportional reasoning, depending on the reasoning…

The purpose of this research was to design and evaluate a computer based adaptive strategy for teaching mathematics. Results indicated preference for materials with personalized examples for motivation and meaningful learning of problem solving procedures. Practical advantages of the computer-based model for adapting instruction are also…

Describes a study of the effect of teachers' verbal feedback on the ability of bilingual sixth graders to solve mathematical word problems. Treatment was based on Mayer's model of problem solving. Results indicated that theory-based feedback targeted to bilingual students' individual and class needs improved student mathematics performance. (GH)

A study investigated the effects of direct instruction in the process of revision on students' knowledge of the revision process, their ability to make revisions on paper, and the quality of their writing. Subjects, 30 sixth grade students, were divided into an experimental and a control group. The experimental group received instruction in the…

This study tested the effectiveness of an experimental instructional strategy for writing arithmetic sentences for simple multiplication and division story problems involving nonintegral factors. Significant effects in favor of the experimental group were found on an intermediate test and a posttest. (Author/CW)

This chapter examines how a particular strategy for analyzing evaluation data, intent-to-treat (ITT) analyses, may underestimate the true effects of interventions. Such underestimation of intervention effects can profoundly influence policies for prevention and treatment of children's mental health problems, which can in turn lead to negative…
