In this paper, we examine the validity and precision of two nonexperimental study designs (NXDs) that can be used in educational evaluation: the comparative interrupted time series (CITS) design and the difference-in-difference (DD) design. In a CITS design, program impacts are evaluated by looking at whether the treatment group deviates from its…

Fifty-four percent of the schools made High Growth and 38% made Expected Growth. All subgroups saw their percentages of students meeting growth increase to above 55% in 2009-10; with the…

This report, the second of three reports examining Supplemental Education Services (SES) within WCPSS, focused on the implementation of SES, and the degree to which short-term and intermediate goals were met. In 2009-10, the SES program was largely implemented with fidelity, with some areas needing refinement related to communication and…

Understanding the meaning of rational numbers and how to perform mathematical operations with those numbers seems to be a perennial problem in the United States for both adults and children. Based on previous work, we hypothesized that giving students more time to practice using rational numbers in an environment that enticed them to apply their…

This meta-analysis synthesizes experimental and quasi-experimental research on instruction that enhances the mathematics performance of K-12 students with learning disabilities. It reports the findings from this synthesis, discusses the implications for practice, and suggests next steps for research and professional development efforts in this…

This report describes results from field-testing of POWERSOURCE[C] formative assessment alongside professional development and instructional resources. The researchers at the National Center for Research, on Evaluation, Standards, & Student Testing (CRESST) employed a randomized, controlled design to address the following question: Does the…

In an effort to identify instructional methods that might improve mathematics learning at the grade 4 level when used in a variety of educational settings under typical conditions, the REL Mid-Atlantic research team looked for promising, replicable practices that were being used broadly by teachers in U.S. schools, for which research showed…

This study investigated whether the software Virtus WalkThrough Pro could be used to enhance middle school children's spatial ability as measured by the Paper Folding, Mental Rotations, and Eliot-Price Tests. The study also investigated whether the use of this software impacted males differently than females, or users with high spatial ability…

In Utah, Migrant Education is a summer-only program offered at 10 sites for children from preschool through high school. Federal funds for programming are allocated to school districts according to enrollment statistics, number of staff, review of program offerings, and fiscal status. The program identifies eligible migrant children and enrolls…

Outcome data are presented for students who participated in the 1985-1986 College Discovery and Development (CDD) program, which is affiliated with the City University of New York, and provides basic skills instruction in reading, writing, and/or mathematics. Information is included on the participants rate; reading, writing, and mathematics test…

In spring and fall 1988, a two-phase study was conducted at Nassau Community College to evaluate two courses in the mathematics program: Preparatory Mathematics (MAT 001) and Introductory Algebra (MAT 002). Pre- and post-tests for the classes were administered to assess student learning outcomes. The first phase of the study examined aspects of…
