The growth of a STEM-focused economy has intensified the focus on developing kindergarten through grade 12 (K-12) students' STEM competencies and on the STEM practices of K-12 STEM teachers. The present study utilised secondary analysis of nationally-representative STEM teacher survey data to examine the ways in which middle grades teachers'…

In prior work, we fit the mixture Rasch model to item responses from a fractions survey administered to a nationwide sample of middle grades mathematics teachers in the United States. The mixture Rasch model located teachers on a continuous, unidimensional scale and fit best with 3 latent classes. We used item response data to generate initial…

Background: The COVID-19 pandemic negatively affected adolescent mental health due to school closures, isolation, family loss/hardships, and reduced health care access. Methods: We compared adolescent mental health in Rhode Island before versus during the pandemic, separately among middle and high schoolers. This serial cross-sectional study used…

The relation between reading and mathematics achievement is an active area of research, and evidence in the extant literature suggests they are closely related. However, there is a lack of understanding about how their relation develops over time. Indeed, traditional longitudinal analyses have focused on investigating each domain independently,…

Purpose: There is little consensus in the literature regarding a) what it means for a school leader to lead with data, and b) how to measure data-informed leadership in a reliable and valid way. This study examines the psychometric properties of an operational measure intended to assess the extent to which a school leader is a data-informed school…

Background: Schools are important contexts for preventing sexual violence (SV) among adolescents. Evaluating whether programming is effective requires surveying youth about SV experiences. However, school communities often have concerns about asking students, particularly those in middle school, about these experiences. This study sought to…

Machine learning (ML) methods for causal inference have gained popularity due to their flexibility to predict the outcome model and the propensity score. In this article, we provide a within-group approach for ML-based causal inference methods in order to robustly estimate average treatment effects in multilevel studies when there is cluster-level…

Education leaders must identify valid metrics to predict student long-term success. We exploit a unique dataset containing data on cognitive skills, self-regulation, behavior, course performance, and test scores for 8th-grade students. We link these data to data on students' high school outcomes, college enrollment, persistence, and on-time degree…

Purpose: Our purpose was to gather and evaluate accurate, up-to-date information on physical education (PE) policy implementation across multiple U.S. states and regions. Methods: A U.S. Physical Education and Physical Activity Policy questionnaire was developed and completed by 4,845 public-school PE teachers from 25 U.S. states. The U.S.…

Research suggests that current teachers' writing instruction does not prepare students for the demands of college and career writing, a problem that has persisted for decades. The purpose of this survey study of third- and fifth-grade teachers (N=159) across the U.S. was 1) to determine changes in teachers' frequency teaching writing using a set…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Monitoring the Future (MTF) is designed to give such attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been funded continuously…

Test-taking experience is a consequence of the interaction between students and assessment properties. We define a new notion, rapid-pacing behavior, to reflect two types of test-taking experience -- disengagement and speededness. To identify rapid-pacing behavior, we extend existing methods to develop response-time thresholds for individual items…

Background: The development of learning attitudes during middle school transition and adaptation is critical, as shown by Self-Determination Theory (SDT). However, the development of adolescents' learning attitudes throughout middle school and the impact of parenting styles on this development remains largely unexplored. Objective: This research…
