The purpose of this explanatory sequential mixed-methods study was to assess the impact of the STEM integration program on third through fifth grade students' achievement scores in mathematics and science in an urban northeastern Georgia school district. In Phase 1, a quantitative research design was used to examine and compare student achievement…

This report summarizes the results of kindergarten through fifth grade students' academic achievement outcomes in mathematics and science following four years of campus-level participation in the Launching Elementary Academic Foundations (LEAF) to STEM program. The LEAF to STEM Program consists of three key components that were adapted for K-5…

Although the Every Student Succeeds Act sets the parameters for parents and families to be involved in their children's education, there are no specified guidelines on how that involvement should be designed to best impact student achievement. The purpose of this study was to compare Grade 3-5 students' mean Milestones test scores in English…

Large numbers of U.S. students lack proficiency in science, and students from different racial/ethnic and socioeconomic groups show disparities in science achievement. Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student achievement in science.…

This study investigated gender disparities in students' science motivational beliefs, conceptualized as self-concept and intrinsic value, from Grades 4 to 8 in 22 countries. The gender-specific relation between science motivational beliefs and achievement was also scrutinized. Data from the 2011 and 2015 national cohorts of the Trends in…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

Background: The importance of valid and reliable instruments for the assessment of factors affecting students' interest in science encouraged the development and validation of a brief Spanish instrument for the measurement of expectancies of success in school science, named SUCCESS. In this study, the psychometric properties of the SUCCESS…

The authors of this exploratory study examine the influence of the Georgia science, technology, engineering, and mathematics (STEM) model; gender; race; and other achievement on elementary students' science outcomes in Title I schools. Results of the study demonstrate that a positive relationship exists between students participating in a…

So far, not enough effort has been invested in developing reliable, valid, and engaging assessments in school science, especially assessment of interdisciplinary science based on the new Next Generation Science Standards (NGSS). Furthermore, previous tools rely mostly on multiple-choice items and evaluation of student outcome is linked only to…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016. Of 30 studies that met inclusion criteria and had data from which an effect size estimate could be calculated, 7 reported science outcomes (18 effect size estimates) or…

The Houston Independent School District (HISD) offers two primary bilingual programs for Spanish-speaking English learners (ELs). EL students in the district's two main bilingual programs (Transitional and Dual Language) are instructed in both English and Spanish. The relative amount of instruction in each language depends on both program and…

Theory and limited research indicate that race and socioeconomic status (SES) interact dynamically to shape children's developmental contexts and academic achievement, but little scholarship examines how race and SES intersect to shape Black-White achievement gaps across development. We used data from the Early Childhood Longitudinal Study,…
