The language of instruction for Deaf children in the American educational system has long been the subject of debate: Should Deaf children learn language via American Sign Language (ASL), English-based visual communication systems, or spoken English only? It has long been the practice of the standard epistemology to encourage the use of verbal…

Our work aims to substantiate and extend earlier findings on the effects of student-teacher race matching on academic achievement using longitudinal data for students in Grades 3 through 8 in Tennessee. We examine heterogenous effects not only by racial subgroup and student preparedness, as explored in prior literature, but also by levels of…

During the 2016-2017 school year, the Vision Partnership program provided vision services to approximately 3,353 students enrolled in the Houston Independent School District. This evaluation brief describes HISD students' participation in campus-based screenings and the Vision Partnership, and the academic achievement of students served by the…

This simulation study examines the measurement precision, item exposure rates, and the depth of the MAP® Growth™ item pools under various grade-level restrictions. Unlike most summative assessments, MAP Growth allows examinees to see items from any grade level, regardless of the examinee's actual grade level. It does not limit the test to items…

This study examined indicators of cheating on a statewide summative assessment for grades 3--8 over a 4-year period. Between year 2 and year 3 of this study, the state launched an aggressive, highly publicized investigation into cheating by educators. The basis of the investigation was an erasure analysis. The current study found that the number…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

Inquiry-based science interventions aim to improve students' science proficiency by helping them understand scientific processes. In these interventions, students conduct hands-on investigations of science concepts and everyday phenomena, construct explanations for what they observe, consider alternative explanations, and communicate and justify…

This report examines how students are performing across the entire 2020-2021 school year in reading and mathematics during the pandemic. Based on insights from millions of student assessments, the report explores key questions effected by COVID-19 in education, including: (1) How much did students grow during the 2020-2021 school year compared…

As a facilitator of the Incredible Years for Teachers Programme (IYT), I have found that the classroom management strategies participant teachers learned during the 6-month programme period have not been embedded and sustained in their use through time. This inquiry investigated the benefits and barriers to IYT being spontaneously, consistently…

This annual report provides information for the 2013-14 school year on grade-level retention and student performance in the Texas public school system. Student retention and promotion data are reported with data on the performance of students in Grades 3-8 on the State of Texas Assessments of Academic Readiness (STAAR) reading and mathematics…

This annual report provides information for the 2014-15 school year on grade-level retention and student performance in the Texas public school system. Student retention and promotion data are reported with data on the performance of students in Grades 3-8 on the State of Texas Assessments of Academic Readiness (STAAR) reading and mathematics…

Individual growth curves yield insights about growth that are not available from any other methodology; and developmental scales based on conjoint measurement models provide unique interpretive advantages for investigations of academic growth. The advantages are apparent when: (1) 15 consecutive statewide reading growth curves are annotated with…

"Achieve3000®" is a supplemental online literacy program that provides nonfiction reading content to students in grades preK-12 and focuses on building phonemic awareness, phonics, fluency, reading comprehension, vocabulary, and writing skills. "Achieve3000®" is designed to help students advance their nonfiction reading skills…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

In the first systematic study of gender achievement gaps in U.S. school districts, we estimate male-female test score gaps in math and English Language Arts (ELA) for nearly 10,000 school districts in the U.S. We use state accountability test data from third through eighth grade students in the 2008-09 through 2014-15 school years. The average…
