Research has begun to show that certain schoolwide characteristics--such as student-centered learning environments, leadership, and safety--can be important for improving student outcomes. In keeping with these insights, school improvement efforts around the country are becoming less narrowly focused on the performance of individual students and…

Background/Context: There is broad agreement about the benefits of taking AP and/or IB courses in high school. Nonetheless, student access to such courses remains uneven and inequitable, due largely to the practice of tracking students by perceived "ability." These tracking practices are often defended based on the contention that…

In spring 2015 Mississippi began testing the college readiness of all grade 11 public high school students and found that approximately 18 percent were ready for college math, a percentage that had changed little by 2017/18. This study examined: (1) the sequences of math courses that Mississippi students took in grades 6-11; (2) the math…

The present study reports on the psychometric defensibility of the Psychological Wellbeing and Distress Screener (PWDS), which is a 10-item self-report behavior rating scale for measuring youth's bidimensional (also known as dual-factor or two-continua) mental health. The PWDS was developed using preexisting items within the Health Behavior in…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

Social Perception Training (SPT) is a program focused on changing the perceptual and cognitive processes involved in suboptimal social interactions. It is administered with whole class of pupils over ten weeks. No previous studies have evaluated its efficacy. The present study investigated the outcome benefit of the program in 18 primary and…

Background: A number of methods to investigate growth have been reported in the literature, including hierarchical linear modelling (HLM), latent growth modelling (LGM), and multidimensional scaling applied to longitudinal profile analysis (LPAMS). Aims: This study aimed at modelling the mathematics growth of students over a span of 6 years from…

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…

While there is widespread agreement that one-size-fits-all professional development (PD) initiatives have limited potential to foster teacher learning, much existing PD is still designed without attention to teachers' motivations and needs. This paper shows that the strengths and weaknesses of middle school mathematics teachers that engage in PD…

This study examined the contributions of vocabulary and spelling to the reading comprehension of students in grades 6-10 who were and were not classified as English language learners. Results indicate that vocabulary accounted for greater between-grade differences and unique variance (?R[superscript 2] = 0.11-0.31) in comprehension as compared to…

This report outlines the development, methodology, and results of the split-half administration of the 2015 School Crime Supplement (SCS) to the National Crime Victimization Survey (NCVS). The National Crime Victimization Survey (NCVS) is sponsored by the U.S. Department of Justice, Bureau of Justice Statistics (BJS). The National Center for…

This article focuses on vocabulary in the context of English-medium instruction at an international high school in Germany. Longitudinal testing was carried out using the Vocabulary Levels Test (VLT) (Nation, 1983; Schmitt, Schmitt, & Clapham, 2001), with 468 participants tested on entry to their first year of secondary school (Grade 6, aged…

This paper reports on findings from the first Western Australian Survey of Educators of Sexuality Education, which aimed to assess the state of relationships and sexuality education (RSE) in the state of Western Australia. Key findings show that secondary school teachers provided more hours of RSE instruction than the national average. However,…
