Research suggests that elementary English Learners (ELs) benefit from interactive dual-language vocabulary instruction delivered one-on-one or in small groups. However, there are many barriers to providing this type of instruction to all ELs, including time constraints and bilingual teacher shortages. Thus, there is a high need for innovative,…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study designed to measure trends in mathematics and science achievement at the fourth and eighth grades, as well as to collect information about educational contexts (such as students' schools, teachers, and homes) that may be related to student…

The Early Fractions Test is a paper-pencil test designed to measure mathematics achievement of third- and fourth-grade students in the domain of fractions. The purpose, or intended use, of the Early Fractions Test is to serve as a student pretest covariate and a test of baseline equivalence in the larger study. In this report, we discuss our…

This report provides a description of the development process, field testing, and psychometric properties of the fall 2015 grades 3-5 Elementary Mathematics Student Assessment (EMSA), a student mathematics test designed to be administered in a whole-group setting to students in grades 3, 4, and 5. The test was administered to 2,614 participating…

The purpose of this study is to evaluate, using a randomized experimental design, the efficacy of TERC's "Using Data" program to change teacher behavior and improve student learning outcomes. The "Using Data" intervention provides professional development and technical assistance to teachers to help them use data…

A curriculum was developed for 18 at-risk students at the fourth grade level, integrating state minimum skills for math and communication. The goal was to teach basic skills and critical thinking skills (CTS), and to see an increase in motivation, self-esteem, and student attendance through a hands-on project of building a dollhouse and its…
