We present a method for data-based decision making at the school level using student achievement data. We demonstrate the potential of a national assessment database [i.e., the University of Oregon DIBELS Data System (DDS)] to provide comparative levels of school-level data on average student achievement gains. Through the DDS as a data source,…

This study examined the predictive validity of formative assessments embedded in a Tier 2 intervention curriculum for kindergarten students identified as at risk for reading difficulty. We examined when (i.e., months during the school year) measures could predict reading outcomes gathered at the end of kindergarten and whether the predictive…

The purpose of this article is to describe passage effects on "Dynamic Indicators of Basic Early Literacy Skills--Next Edition Oral Reading Fluency" ("DIBELS Next ORF") progress-monitoring measures for Grades 1 through 6. Approximately 572 students per grade (total "N" with at least one data point = 3,092) read all…

This study operationalizes four measures of instructional differentiation: one for Grade 2 English language arts (ELA), one for Grade 2 mathematics, one for Grade 5 ELA, and one for Grade 5 mathematics. Our study evaluates their measurement properties of each measure in a large field experiment: the Indiana Diagnostic Assessment Tools Study, which…

Proficiency in mathematics, including mathematical reasoning skills, requires students to communicate their mathematical thinking. Mathematical reasoning involves making sense of mathematical concepts in a logical way to form conclusions or judgments, and is often underdeveloped in students with learning disabilities. Technology-based environments…

Despite the emerging evidence base on response to intervention, there is limited research regarding how to effectively use progress-monitoring data to adjust instruction for students in Tier 2 intervention. In this study, we analyzed extant data from a series of randomized experimental studies of a kindergarten supplemental reading intervention to…

In "Reading First" schools throughout the United States, literacy coaches administer the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) as the sole measure of fluency and then offer instructional recommendations for students with reading difficulties based on those results. However, critics of DIBELS question its accuracy for…

Progress monitoring refers to a system of ongoing data collection on academic skills of interest. Short samples of student performance are collected on a regular basis, and the scores from these short samples of performance are graphed to create a picture of student progress. Teachers can use the graphed student performance as they make…

This causal/comparative study answered: Does the attainment of year-end kindergarten reading benchmark status vary between students enrolled in half-day kindergarten and those enrolled in full-day kindergarten after controlling for differences in initial instructional recommendations? The researcher analyzed the 2005-2006 achievement of 906…

The purpose of this study was to determine the relationship between the Dynamic Indicators of Basic Early Literacy Skills (DIBELS), the Reading Recovery Observation Survey (RROS) early reading sub-tests, and the reading achievement of Native American first-graders as measured by the Stanford 10. A causal-comparative correlation research design…

This study examined the impact of Oregon Reading First on student reading outcomes. Outcomes in schools that began Reading First implementation in 2003-2004 (Cohort A) were compared to outcomes in schools that began Reading First implementation in 2005-2006 (Cohort B). The primary hypothesis, that experienced Cohort A schools would outperform…
