We report a novel survey that narrows the gap between information about teachers' knowledge of fraction arithmetic provided, on the one hand, by measures practical to administer at scale and, on the other, by close analysis of moment-to-moment cognition. In particular, the survey measured components that would support reasoning directly with…

Using data from the Early Childhood Longitudinal Study--Kindergarten cohort (ECLS-K), this study aimed to identify body mass index (BMI) trajectories from kindergarten to eighth grade using group-based trajectory modeling (GBTM), examine the relationships between BMI trajectories and adolescents' school achievement (reading and math), determine…

Middle school general music is an often-overlooked aspect of music education in the United States. Yet at some point, many music educators face a teaching assignment including one or more sections of middle school general music. In this study, I investigated whether the principles that guide music educators in teaching middle school general music…

Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n =…

This study aimed to investigate the factors accounting for science learning self-efficacy (the specific beliefs that people have in their ability to complete tasks in science learning) from both the teacher and the student levels. We thus propose a multilevel model to delineate its relationships with teacher and student science hardiness (i.e.,…

Purpose: This study examined California middle school physical education teachers' (grades 6-8) use of assessments based on state standards to grade their students. Methods: An electronic survey was used to collect data. Results: Of the 309 teachers surveyed, 74% based their assessments on the state physical education standards. Teachers who used…

Environmental education (EE) aims to create environmentally literate individuals that have the knowledge, skills, and dispositions to solve important environmental issues. However, little research examines whether and which educators' emotional support behaviors, such as responsiveness and positive communications, enhance outcomes in an EE…

This policy brief summarizes the responses by early-career science, technology, engineering and math (STEM) teachers in Washington State to the Washington STEM Teacher Survey. These early-career STEM teachers were asked about their perspectives of their teacher education program (TEP) and STEM subject preparation, with a focus on their student…

The 2-parameter logistic multidimensional item response theory (MIRT) model was employed to model growth for the National Education Longitudinal Study of 1988 (NELS:88). The 3 measurement waves of NELS:88 (base year, first follow-up, and second follow-up) represented 3 dimensions.The inquiry aimed to improve modeling performance growth based on…

This design-based research investigated the context and impact of a three-year practice-based professional development (PD) project introducing science teachers to pedagogical shifts required for full implementation and synergy among disciplinary literacy components of "Next Generation Science Standards" and "Common Core State…

Project Tomorrow® designed and implemented an online survey in spring 2021 to collect both quantitative and qualitative feedback from Summit Learning teachers nationwide.
