This study sought to investigate whether there were performance differences between the children who engaged with the Ignite by Hatch™ educational gaming system using the English- or Spanish-language versions of the games. Differential item functioning methods (DIF) were employed to investigate these differences. Specifically, DIF analyses can…

The current project, Exploring Math Education Relations by Analyzing Large Data Sets (EMERALDS) II, is an attempt to identify specific Common Core State Standards procedural, conceptual, and problem-solving competencies in earlier grades that best predict success in algebraic areas in later grades. The data for this study include two cohorts of…

The aim of the research reported here was to get some idea of the accuracy of grade boundaries (cut-scores) obtained by applying the 'similar items method' described in Bramley & Wilson (2016). In this method experts identify items on the current version of a test that are sufficiently similar to items on previous versions for them to be…

The tables in this report include data from the 2019 School Crime Supplement (SCS) to the National Crime Victimization Survey (NCVS). These tables show the extent to which students, ages 12 through 18, with different characteristics report being bullied, including estimates by student sex, race/ethnicity, grade, and household income. The U.S.…

The ED School Climate Surveys (EDSCLS) are a suite of survey instruments being developed for schools, school districts, and states by the U.S. Department of Education's National Center for Education Statistics (NCES). Through the EDSCLS, schools nationwide will have access to survey instruments and a survey platform that will allow for the…

In the Cognitively Based Assessment of, for, and as Learning ("CBAL"™) research initiative, innovative K-12 prototype tests based on cognitive competency models are developed. This report presents the statistical results of the 2 CBAL Grade 8 writing tests and 2 Grade 7 reading tests administered to students in 20 states in spring 2011.…

The POWERSOURCE[c] intervention is intended as a generalizable and powerful formative assessment strategy that can be integrated with any mathematics curriculum. POWERSOURCE[c] includes both a system of learning-based assessments and an infrastructure to support teachers' use of those assessments to improve student learning. The core undertaking…

Due to their motivational nature, there has been growing interest in the potential of games to help teach academic content and skills. This report examines how different levels of detail about a game's scoring rules affect math learning and performance. Data were collected from 164 students in the fourth to sixth grades at five after-school…

This study examined the scores on a state standards-based Grade 5 Science assessment obtained by a group of students without learning disabilities who took the standard form of the test and by three groups of students with learning disabilities: one taking the standard form of the test without accommodations or modifications, a second taking the…

The purpose of the study is to present research focused on validating the four algebra cognitive models in Gierl, Wang, et al., using student response data collected with protocol analysis methods to evaluate the knowledge structures and processing skills used by a sample of SAT test takers.

This study was conducted in order to evaluate available linking techniques for forming large item pools and to make recommendations as to which techniques should be used under various circumstances. Variables of interest included calibration model and procedure, sample size, overlap level, and linking procedure. The calibration models considered…

Using an empirical investigation of alternate item nonresponse adjustment procedures in a National Longitudinal Study (NLS) of missing and faulty data, it is indicated that in some cases imputation can reduce the accuracy of survey estimates. A National Sample of the high school class of 1972 is designed to provide statistics on students moving…

A table is provided and described for prorating Minnesota Multiphasic Personality Inventory scales when the entire Form R has not been completed. Good concordance of profile types was found for 300 and 350 completed questions. Interpretations based on 200 items may be suspect. (Author)

"Naturalization Test Redesign Project: Civics Item Selection Analysis" provides an overview of the development of content items for the U.S. history and government (civics) portion of the redesigned naturalization test. This document also reviews the process used to gather and analyze data from multiple studies to determine which civics…

This study explored whether the addition of the items with more advanced math content to the SAT Reasoning Test™ (SAT®) would impact test-taker performance. Two sets of SAT math equating sections were modified to form four subforms each. Different numbers of items with advanced content, taken from the SAT II: Mathematics Level IC Test (Math IC),…
