Understanding the extent to which youth and families experienced COVID-related stress requires accounting for prior levels of stress and other associated factors. This is especially important for military families, which experience unique stressors and may be reluctant to seek outside help. In this prospective study, we examined the role of…

Boys and girls sit together in most classrooms, but do they interact? Based on forty-year-old evidence, coeducational classes may not be coeducational but instead be segregated by gender, which may undermine student success. Our goal is to answer this question in today's classrooms. We used longitudinal data to assess gender segregation in 26…

Teachers' efforts to manage classroom social dynamics are associated with students' social and academic adjustment, but the determinants of teachers' use of social dynamics management strategies have remained unexplored. Multiple potential determinants of strategy use were examined in a study of 164 teachers and their 2,986 students in 164 1st,…

Most US students attend coeducational classes, but to what extent do students feel integrated into the entire classroom of their peers, especially with other-gender peers? The major goal of this research was to investigate how variations in gender integration (GI), measured by students' expectancies about inclusion, efficacy, and social costs of…

Purpose: The Santa Ana Unified School District received an i3 grant (Investing in Innovation; funded by the U.S. Department of Education Grant number U411C160074) to build on their existing school climate practices. Called the Enhanced Positive School Climate Model, the aim is to improve school climate, student-adult relationships, create social…

Interactive Writing (IW) is a powerful support for language and literacy development; however, its emphasis on using oral language to construct written language can present challenges for deaf/Deaf and hard of hearing (d/Dhh) students due to their unique and diverse language experiences. Teachers (n = 14) using Strategic and Interactive Writing…

Previous studies offer mixed evidence regarding whether a unified model of reading comprehension predictors applies to Dual Language Learners (DLLs) and English Speakers (ESs), or whether distinctive models across language groups are empirically supported. The present study adds another dimension to this body of work by examining multiple reading…

Staff turnover may have important consequences for the development of collective social resources based on trust, shared norms, and support among school professionals. We outline the theoretical role-specific consequences of principal and teacher turnover for features of principal leadership and teacher community, and we test these ideas in…

This research summary accompanies the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in…

Students' academic achievement is the result of the interplay between person-level and contextual factors (R. R: Greene, 2014; D. E. Hunt, 1975). Students perform better when classroom characteristics support their characteristics. The authors examine whether student perceptions of two classroom characteristics (care and control) fit with two…

Growing up in poverty increases youth risk for developing aggressive behavior problems which, in turn, are associated with a host of problematic outcomes, including school drop-out, substance use, mental health problems, and delinquency. In part, this may be due to exposure to adverse school contexts that create socialization influences supporting…

Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the release of the Next Generation Science Standards (NGSS) in 2013. The new standards set off a chain reaction of standards adoption and…

Student models for adaptive systems may not model collaborative learning optimally. Past research has either focused on modeling individual learning or for collaboration, has focused on group dynamics or group processes without predicting learning. In the current paper, we adjust the Additive Factors Model (AFM), a standard logistic regression…
