Educators and researchers have long debated the best grade configuration grouping for middle grade students. This study examined school-level differences in reading and mathematics standardized test pass rates for students placed in middle schools versus alternative grade configurations. Latent growth modeling was conducted separately for 6th,…

Too many talented students who go to under-resourced schools do not achieve their full potential. Though they may perform very well relative to their classmates, these students do not receive the same kinds of academically challenging opportunities throughout their educational journey as do their counterparts in better-resourced public and private…

Northwest Evaluation Association™ (NWEA™) is committed to providing partners with useful tools to help make inferences from the Measures of Academic Progress® (MAP®) interim assessment scores. Recently, NWEA completed a concordance study to connect the scales of the Virginia Standards of Learning (SOL) reading and math tests with those of the MAP…

This study of 952 fifth and sixth graders in Washington, DC, and Alexandria, Virginia, found that students who were offered the "Higher Achievement" program had higher test scores in mathematical problem solving and were more likely to be admitted to and attend private competitive high schools. "Higher Achievement" is a…

The purpose of this study was to determine the extent that diagrammatic literacy is necessary for success on standardized science tests at the late-elementary and middle grade levels. Towards this goal, we quantified the frequency, form and function of graphical representations on select state science tests. 985 tests items from 14 states were…

Intelligent tutors have become increasingly accurate at detecting whether a student knows a skill, or knowledge component (KC), at a given time. However, current student models do not tell us exactly at which point a KC is learned. In this paper, we present a machine-learned model that assesses the probability that a student learned a KC at a…
