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…

Three studies involving elementary students examined methodological issues in curriculum-based reading assessment. Results indicated that (1) whereas sample duration did not affect concurrent validity, increasing duration reduced performance instability and increased performance slopes and (2) domain size was related inversely to performance slope…

The meta-analysis investigated the effects on achievement of type of graphing paper employed in displaying student performance data collected over time based on 15 controlled studies with 16 effect sizes. No significant differences in student achievement were found between studies using six-cycle and studies using equal interval paper graphing…

The purpose of this study was to determine the proportion of empirical studies published in the last 5 years in a sample of special education peer-reviewed journals that: (1) assessed the effects of reading and math interventions with group designs and; (2) used random assignment to treatment conditions to test those interventions. A hand search…

This review examined the literature on peer tutoring in reading with students with disabilities, using the methodology of best evidence synthesis. This approach combines positive aspects of meta analysis with traditional integrative review procedures. It requires all studies reviewed to meet stringent a priori standards. Analysis of the 11 studies…

This experimental study examined the influence of a classwide peer-tutoring reading program (Peer-Assisted Learning Strategies; PALS) on the quality of social relationships of elementary school children. Using a sociometric procedure, social preference and friendships were evaluated before and after the PALS program. Overall (mean) and…

This paper presents a comprehensive review of special and remedial education practice in formative evaluation of goal attainment among mildly handicapped students. First, the relationship of formative evaluation to the range of special education assessment practice and its importance to the field are described. Then, four critical issues in…

This article presents a meta-analysis of the effects of examiner familiarity/unfamiliarity on children's performance during individual testing. Data came from 22 controlled studies involving 1489 subjects. In a typical study, the effect of examiner familiarity raised test performance by .35 standard deviations. Differential performance favoring…

While the aptitude treatment interaction (ATI) approach to educational measurement emphasizes establishing salient learner characteristics, systematic formative evaluation provides ongoing evaluation for instructional program modification. Systematic formative evaluation appears more tenable than ATI for developing individualized instructional…
