Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…

The PreACT® suite of assessments (PreACT® 8/9, PreACT®, and PreACT® Secure™) can be used to monitor students' progress toward college and career readiness. Scores are classified into one of three readiness levels based on chances of meeting the ACT College Readiness Benchmark. This data byte presents the updated score ranges for each readiness…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

How does the act of explaining influence learning? Prior work has studied effects of explaining through a predominantly proximal lens, measuring short-term outcomes or manipulations within lab settings. Here, we ask whether the benefits of explaining extend to academic performance over time. Specifically, does the quality and frequency of student…

We examine the effect of attending stand-alone technical high schools in Connecticut using regression discontinuity. Male students are 10 percentage points more likely to graduate from high school and have half a semester less time enrolled in college. Male students have 32% higher average quarterly earnings. Earnings effects may in part reflect…

NWEA claimed their assessment results could accurately predict student performance in reading and mathematics on the ACT Aspire for students in Grades 7 through 10. The purpose of this study was to determine the relationship between students' scores on the NWEA MAP tests in reading and mathematics and the ACT Aspire for students in Grades 7…

Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent--but doing so often requires the use of…

This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The…

We report results of 2 studies examining the relation between decoding and reading comprehension. Based on our analysis of prominent reading theories such as the Simple View of Reading (Gough & Tunmer, 1986), the Lexical Quality Hypothesis (Perfetti & Hart, 2002) and the Self-Teaching Hypothesis (Share, 1995), we propose the Decoding…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

Based on our analysis of prominent reading theories such as the Simple View of Reading (Gough & Tunmer, 1986), the Lexical Quality Hypothesis (Perfetti & Hart, 2002) and the Self-teaching Hypothesis (Share, 1995), we propose the Decoding…

Despite the recognized importance of morphological knowledge to literacy outcomes such as vocabulary knowledge and reading comprehension, two of its subconstructs--morphological awareness and morphological processing--have received comparatively little attention. In response, the aim of the study reported here was to examine how the relationships…

The present study explores the longitudinal development between Grade 3 word level reading skills and higher level semantic skills to Grade 10 reading comprehension for 3,157 students. In particular, this work focused on how the developmental relations varied for subsamples of students who are English learners (EL; N = 308), students identified as…

Purpose: This study examined the agreement between estimated peak oxygen consumption (VO[subscript 2peak]) obtained from the Progressive Aerobic Cardiovascular Endurance Run (PACER) fitness test and equated PACER laps derived from One-Mile Run time (MR). Methods: A sample of 680 participants (324 boys and 356 girls) in Grades 7 through 12…

This research examined the extent to which benchmark assessments can be accurate forecasters of student performance on a state assessment in Algebra 1. The study applied correlational analysis, regression analysis, and receiver operator characteristic (ROC) analysis to the benchmark and state assessment results of a rural school district in…
