The goal of Smithsonian Science for North and South Carolina Classrooms was to provide teachers with ongoing, differentiated professional development and research-based curricular materials to improve elementary student achievement in science, mathematics, and reading. This work used an inquiry-based science curriculum, Smithsonian Science for the…

The five-year project, "Smithsonian Science for North and South Carolina Classrooms" (hereafter "Smithsonian Science"), offers important evidence on the impact of the phenomena-driven science curriculum, "Smithsonian Science for the Classroom," paired with ongoing, differentiated, high-quality professional learning…

The current study reports on a large-scale quantitative analysis of classroom talk practices and links to different measures of reading achievement within upper elementary classrooms. Data involving 745 fourth- and fifth-grade teachers and 18,844 students from the Measures of Effective Teaching (MET) study were used. Talk was quantified via…

A nonexperimental design was used to determine whether the verbal scores of low-income gifted fifth graders (n = 38) differed from those of their higher income peers (n = 83). The Otis-Lennon School Ability Test, Eighth Edition and the Stanford Achievement Test-Tenth Edition were used to collect student data. Results of a MANOVA showed a…

This study examined the viability of the Sentence Verification Technique (SVT; Royer, Hastings, & Hook, 1979) assessment tool as a curriculum-based measure of science content learning. Its perceived compatibility with statewide accountability test expectations made SVT a candidate for use in content-focused response to intervention frameworks.…

This study presents estimates of Black-White, Hispanic-White, and income achievement gaps using data from two different types of reading and mathematics assessments: constructed-response assessments that were likely more cognitively demanding and state achievement tests that were likely less cognitively demanding (i.e., composed solely or largely…

The amount of research evaluating the technical merits of general outcome measures of science and social studies achievement is growing. This study targeted criterion validity for critical content monitoring. Questions addressed the concurrent criterion validity of alternate presentation formats of critical content monitoring and the measure's…

The purpose of this quantitative, causal-comparative study was to compare the effect elementary music and visual arts lessons had on third through sixth grade standardized mathematics test scores. Inferential statistics were used to compare the differences between test scores of students who took in-school, elementary, music instruction during the…

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…

The present research sought to determine if primary school students differentiate between classes that are challenging and those that are difficult, and how these distinctions relate to their motivation and achievement. Results indicated that there are three types of challenges/difficulties. "Challenging" classes are those that are…

This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, a.k.a. "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However,…

The purpose of this report was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on science performance of students whose teachers participated in the program during summer 2013. Paired t-test results showed statistically significant increases in the BCM students' Stanford 10 science performance at the…

The purpose of this study was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on teacher science content knowledge and students' science performance. The analysis of the effect of participation showed an increase of 253 scale score points on the 2015 State of Texas Assessments of Academic Readiness,…

This study investigates, through a cluster randomized trial, the impact of "Math in Focus," a core mathematics program modeled after instructional approaches used in Singapore, on third- through fifth-grade students' achievement in mathematics. The program is currently being used in more than 400 school districts in the United States.…
