The goal of this study was to describe fraction-calculation errors among fourth-grade students and to determine whether error patterns differed as a function of problem type (addition vs. subtraction; like vs. unlike denominators), orientation (horizontal vs. vertical), or mathematics-achievement status (low-, average-, or high-achieving). We…

The goal of the present study was to describe fraction-calculation errors among 4th-grade students and determine whether error patterns differed as a function of problem type (addition vs. subtraction; like vs. unlike denominators), orientation (horizontal vs. vertical), or mathematics-achievement status (low- vs. average- vs. high-achieving). We…

All students should have opportunities to develop their ability to reason mathematically. Gersten and Chard (1999) support this stance with respect to students with learning disabilities: "Even if students are not automatic with basic facts, they still should be engaged in activities that promote the development of number sense and…

Although approximately 5-8% of students have a mathematical learning disability (MLD), researchers have yet to develop a consensus operational definition. To examine how MLD has been identified and what mathematics topics have been explored, the authors conducted a systematic review of 165 studies on MLD published between 1974 and 2013. To move…

The purpose of this analysis was to examine achievement gaps on fractions for very-low-performing students as a function of whether they receive inclusive fraction instruction or specialized fraction intervention and with the shift to Common Core State Standards (CCSS). In three randomized control trials conducted in 3 consecutive years, 203…

The purpose of this set of analyses, conducted on a randomized control trial examining the effects of a fourth-grade fraction intervention, was to assess the initial academic deficit severity hypothesis. With this hypothesis, at-risk students with more severe initial academic deficits are expected to profit less from intervention than do students…

Three cohorts of third-grade students (N = 813) were evaluated on achievement, cognitive abilities, and behavioral attention according to contrasting research traditions in defining math learning disability (LD) status: low achievement versus extremely low achievement and IQ-achievement discrepant versus strictly low-achieving LD. We use methods…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

Stakeholders are debating the value of cognitively focused instruction for students who have not benefited from a skills-based approach. Much of the discussion, however, is occurring without recognition of research that has been conducted in the past 2 decades. In this article, we reviewed the research. Electronic databases and hard copies of…

The purpose of this study was to assess the relative contribution of teacher and tutor ratings of inattentive behavior in two different instructional settings in predicting students' performance on fraction concepts and whole-number calculations. Classroom teachers rated each student's attentive behavior in a whole-class setting and tutors rated…

This study utilized a sample of 159 inmates from a small Northwest Indiana correctional facility to examine the educational attainment and literacy proficiency of the inmates. The 3rd edition of the Wide Range Achievement Test (WRAT-3) was used to assess the spelling, reading and arithmetic achievement of the inmates. Overall the results of this…

A comparison of reading subtests of the Wide Range Achievement Test, Peabody Individual Achievement Test, and Slosson Oral Reading Test showed a high correlation between the WRAT and PIAT. Suggests the WRAT and PIAT measure the same dimension of reading achievement, possibly verbal fluency. (Author/JAC)

THE GENERAL CURRICULUM PROGRAM WAS ESTABLISHED FOR BUILDING OF SKILLS AND DEVELOPMENT OF BREADTH OF BACKGROUND IN PREPARATION FOR CONVENTIONAL COLLEGE CLASSES. PRETESTS AND POST-TESTS WERE EVALUATED FOR 165 STUDENTS AFTER ONE SEMESTER IN THE PROGRAM AND SHOWED SIGNIFICANT INCREASES IN ACADEMIC SKILL LEVEL, WRITING, AND READING. SIMILAR RESULTS…
