The contributions of domain-general abilities and domain-specific knowledge to subsequent mathematics achievement were longitudinally assessed (n = 167) through 8th grade. First grade intelligence and working memory and prior grade reading achievement indexed domain-general effects, and domain-specific effects were indexed by prior grade…

This study investigated the complexity of leveled passages used in four classroom reading assessments. A total of 167 passages leveled for Grades 1-6 from these assessments were analyzed using four analytical tools of text complexity. More traditional, two-factor measures of text complexity found a general trend of fairly consistent across-grade…

This report looks at student growth in Arkansas school districts disaggregated by district poverty and by the district's value-added performance relative to other districts. We estimated district value-added performance statistics by subject and grade level (8 and 11-12) for longitudinal student cohorts, using statistical models that adjusted for…

It is often assumed that a vertical scale is necessary when value-added models depend upon the gain scores of students across two or more points in time. This article examines the conditions under which the scale transformations associated with the vertical scaling process would be expected to have a significant impact on normative interpretations…

This report examines the relationship between socioeconomic status, as defined by a free-and-reduced lunch proxy variable, and student growth percentiles by elementary, middle, and high school grade levels for math, reading, and writing. Comparisons were made between median growth percentiles for each educational level by free and reduced lunch…

Background: While existing evidence strongly suggests that immigrant students underperform relative to their native counterparts on measures of mathematics, science, and reading, country-level analyses assessing the homogeneity of the immigrant achievement gap across different factors have not been systematically conducted. Beyond finding a…

Common Core Reading Standard 10 not only prescribes the difficulty of texts students should become able to read, but also the difficulty diet of texts schools should ask their students to read across the school year. The use of quantitative text-assessment tools in the implementation of this standard warrants an examination into the validity of…

For over thirty years, research has been conducted on the relative benefits of integrating the sixth through eighth grades within the structure of the K-8 elementary school or of establishing a freestanding middle school structure. While the available research clearly supports the positive effects of the K-8 structure on academic achievement in…

This report measures trends in performance among urban schools receiving federal School Improvement Grant (SIG) awards as part of the American Recovery and Reinvestment Act of 2009 (ARRA). The Council of the Great City Schools aims to document how member districts of the Council of the Great City Schools implemented SIG and specifically what…

In this report, the authors describe the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in Race to the Top. They estimated (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…

This paper examines students' perceptions of their classroom environment and the possible effect of these perceptions on math and reading achievement. Additionally, the paper investigates the significance of gender and grade level on students' perceptions of the classroom environment. Participants were elementary school students in a large urban…

The study analyzes the achievement trends of all third grade students in the state of Illinois who scored in the Exceeds category in reading and mathematics on the Illinois Standards Achievement Test (ISAT) in the year 2000. ISAT performance of this cohort group of students was followed through the eighth grade. Descriptive analyses were utilized…

THIS REPORT EVALUATES THE PROGRESS OF 14 PILOT INTERMEDIATE SCHOOLS ORGANIZED IN SEPTEMBER 1966 INTO EITHER A 6-7-8 OR A 5-6-7 GRADE STRUCTURE. NINE OF THE SCHOOLS SERVE CHILDREN IN ECONOMICALLY DISADVANTAGED AREAS. A SPECIALLY REVISED CURRICULUM WAS INTRODUCED INTO THE PILOT SCHOOLS AT THE SIXTH-GRADE LEVEL. EXTENSIVE TEACHER TRAINING PRECEDED…
