This paper is the first to examine the longitudinal results of six years of implementation of Literacy Squared, a biliteracy model for Spanish/English speaking emerging bilingual students. This model includes paired literacy instruction with grade-specific time allocations for Spanish literacy and literacy-based ELD. Furthermore, cross-language…

The aim of this study was to measure the impact of the overall school facility condition for traditional Colorado elementary schools, according to Colorado's Facilities Conditions Index (FCI), on student achievement, as measured by the Colorado Student Assessment Program (CSAP). Control variables included Special Education (SPED), English Language…

Competency-based education has received growing attention in recent years as a way to address preK-12 learning goals. In competency-based education, students are promoted to the next course of study or grade level in each subject area after demonstrating mastery of identified learning targets aligned to standards. Westminster Public Schools in…

Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…

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…

The American Association of School Librarians (AASL) Standards for the 21st Century Learner do not just pay lip-service to the value of reading. They have been aligned with the Common Core standards that were derived from, and now influence, state standards-based tests, such as the Colorado Student Assessment Program (CSAP) reading tests. It is…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This study examined the relationship between oral reading fluency and performance on a statewide reading test across Grades 3, 4, and 5. A curriculum-based measure of oral reading fluency was administered to 3rd, 4th, and 5th graders who participated in the reading test from the Colorado Student Assessment Program (CSAP). A cross-sectional design…
