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…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016.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…

In Fall and Winter 2022-2023, the NSCAS assessments were administered in ELA and mathematics for grades 3-8. In Spring 2022-2023, the NSCAS assessments were administered in English language arts (ELA) and mathematics for grades 3-8 and in science for grades 5 and 8. The purposes of the NSCAS assessments are to measure and report Nebraska students'…

Studying nature from the atomic and molecular perspective gives students access to modern scientific paradigms and could improve achievement and motivation towards science learning. A visual and tactile approach to chemistry can form the foundation for a child-friendly but high-level chemistry curriculum and could be a powerful tool to invigorate…

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3-4-5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and…

In 2013, the National Board for Professional Teaching Standards received a 5-year Investing in Innovation Fund Development grant from the U.S. Department of Education to develop, implement, and study Accomplished Teaching, Learning, and Schools (ATLAS). ATLAS is an online case library that contains examples of "accomplished teaching"…

This report demonstrates the effects of the Arkansas Better Chance program (ABC) on late elementary and middle school outcomes. End of year assessments, which varied over the course of the study years, were examined for students of three preschool cohorts. Students included in the statewide study received free lunch all years and were enrolled in…

Measures of Academic Progress® (MAP®) Science for use with Next Generation Science Standards (NGSS) assessments are available for the 2016-17 school year. These new assessments measure student growth toward understanding of the multidimensional NGSS performance expectations. This report presents MAP Science for use with NGSS by presenting and…

This report demonstrates the effects of the Arkansas Better Chance program (ABC) on late elementary and middle school outcomes. End of year assessments, which varied over the course of the study years, were examined for students of three preschool cohorts. Students included in the statewide study received free lunch all years and were enrolled in…

Students' interest in science declines substantially in the transition from elementary to secondary education. Using students' ratings of their instruction on the topic of evaporation and condensation, we examined if changes in instructional practices accounted for differences in situational interest in science instruction and enduring individual…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…
