Guided by the social-ecological, social identity, and social misfit theories, the present study examined the gender, racial/ethnic, and grade-level differences of students' perceived school safety and their associations with bullying victimization and school-wide bullying using a sample of 25,896 students from 114 public schools. Results of…

Tenets of the Boivin et al. (1995) social process model were reexamined with two longitudinal samples using both the original and contemporary analytic strategies. Study goals included reconstructing (e.g., quasireplicating) Boivin et al.'s (1995) original findings and evaluating hypothesized relations across both comparable and longer…

This work presents a discussion about the Didactic Training Engineering (EDF) methodology, of French origin, emphasizing the role of the teacher, during his initial or continuous training, through the conception and structuring of a didactic situation, organized by such methodology and based on the Theory of Didactic Situations (TSD). Therefore,…

In this paper we analyze the extent to which a mandated kindergarten assessment predicts 3rd grade outcomes, and the academic progression for students from 3rd grade to high school. We find that the kindergarten assessment strongly predicts 3rd grade outcomes, with the math skills assessment being especially predictive of 3rd grade academic…

Achieving scientific literacy is an essential outcome of science education and is comprised of knowledge of scientific content, the process of scientific inquiry, and understanding the Nature of Science (NOS; National Research Council, 1996). NOS refers to the characteristics of scientific knowledge that are derived from the results of the process…

This study uses a newly compiled data set of instructional time and student performance by subject across German federal states for student cohorts enrolled at the primary level in the 1990s and tested at the secondary level in the 2000s. It finds evidence for the school inputs-student achievement relationship, taking nonlinearity,…

The current study examined: (1) the associations of COVID-19 stress with anxiety and depression and whether those associations differed by gender or grade level; and (2) how different coping strategies mitigated the associations of COVID-19 stress with anxiety and depression. During remote learning due to COVID-19, data were collected from 2,738…

The California Next Generation Science Standards (CA NGSS)--adopted in 2013--have the potential to improve scientific literacy and strengthen the global competitiveness of California's workforce. However, longstanding underinvestment in science education and the unprecedented disruptions caused by COVID-19 have heightened challenges faced by…

This study explores the effect of in-person schooling on youth suicide. We document three key findings. First, using data from the National Vital Statistics System from 1990-2019, we document the historical association between teen suicides and the school calendar. We show that suicides among 12-to-18-year-olds are highest during months of the…

Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent--but doing so often requires the use of…

Bullying is a peer relational problem that can inflict psychological harm onto both those who are victimized and those who witness it occur. Fostering a positive classroom environment is an important protective factor in preventing bullying. Authoritative classroom climates may protect victimized and bystander youth from negative mental health…

This study examined the extent to which disparities in Black and White students' risks of receiving office discipline referrals (ODRs), and out-of-school suspensions (OSSs) were related to differences in implicit and explicit racial biases assessed at the community level. The sample consisted of discipline records for 1,354,010 students enrolled…

Revisions in writing aim at text improvement. Literature has shown that revision activity differs between novice and experienced writers. Our ultimate goal is to understand how children and adolescents develop the capacity to shift perspectives from language producer to language recipient -- a prerequisite ability to successful revision. In this…

Multitiered systems of support (MTSS) is an effective model for identifying students at risk for academic failure as well as behavioral concerns (excesses and deficits) that impede classroom success. Over the years, researchers have investigated the positive effects of the MTSS model on behavioral needs of students; however, to date the research…

Children's work habits at school include being a hard worker, turning in work on time, following classroom rules, and putting forward one's best effort. Models on youth character, noncognitive skills, and social-emotional learning suggest that self-management skills like work habits are critical for individuals' subsequent academic success. Using…
