This commentary summarizes emerging research into fractions instruction for students who are at risk for failure. Each of the three articles emphasizes a measure conception of fractions. Teaching fractions as measurement helps students learn the magnitude of rational numbers. However, measurement is only part of the way that students should…

In this commentary, John Woodward observes that, when judged collectively, the pre-K to Grade 4 research in this special section not only exemplifies the effects of the Institute of Education Sciences' emphasis on large-scale empirical studies over the last decade, but it also demonstrates how the field of special education has moved away from a…

Four studies into characteristics and instructional needs of students with learning disabilities are summarized in this article. These studies are also reviewed in the wider context of mathematics intervention research in special education. These studies generally rely on qualitative methodology, and they are best understood in light of a…

An important component of the National Council of Teachers of Mathematics Standards is the equity principle: All students should have access to a coherent, challenging mathematics curriculum. Many in the mathematics reform community have maintained that this principle can be achieved through one well-designed curriculum. However, the extant…

This report describes TORUS, a computer-based program for elementary school students with learning disabilities which analyzes student work samples in addition and subtraction and provides individual profiles of student misconceptions and weaknesses. Initially, work samples from 236 middle school students with learning disabilities were analyzed…

Two studies involving 27 learning-disabled middle-school students and 30 mildly handicapped junior high students investigated use of Teacher Net, a computer networking system that facilitates immediate feedback. Teacher Net reduced the teachers' administrative workload, effectively monitored student understanding, provided feedback to teachers,…

In 1978 a controversial evaluation found no difference in achievement between Hispanic students in transitional bilingual programs and those in regular classroom programs. The authors present an argument favoring the use of stuctured immersion programs instead of bilingual programs. (MD)

The effectiveness of computer simulation in enhancing learning of a health unit by 30 mildly learning-disabled high school students was investigated. Results indicate that computer simulation in combination with structured teaching was effective, particularly in the area of teaching problem-solving skills. (TJH)

TORUS, a prototype technology-based educational diagnostic program, is described. The usefulness of TORUS to identify and remediate the mathematics misconceptions of students with learning disabilities is reported. Results suggest the need for greater emphasis on conceptual understanding in mathematics instruction. (Author/DB)

Classroom communication figures prominently in current math reform efforts. In this study, we analyze how one teacher used writing to support communication in a seventh-grade, low-track mathematics class. For one school year, we studied four low-achieving students in the class. Students wrote in journals on a weekly basis. Using classroom…

This report summarizes a series of eight research studies related to the use of computer-assisted instruction (CAI) with mildly handicapped students at the junior high or high school level. Through videodisc and CAI the studies isolated the effects of the following design variables: (1) review cycles; (2) size of teaching sets; (3) explicit…
