Improving math achievement among U.S. students remains a high priority as results from recent math assessments continue to show room for improvement. For example, 60 percent of fourth-graders scored below the proficient level on the 2015 National Assessment of Educational Progress. On the most recent Program for International Student Assessment's…

Recent results from national and international assessments continue to show a need for improvement in math achievement among U.S. students. For example, 60 per-cent of grade 4 students scored below the proficient level on the 2015 National Assessment of Educational Progress. In an era of increasingly rigorous state standards, teachers at all grade…

This study addresses the effectiveness of a widely used core reading program that reflects the research-based practices recommended by the National Reading Panel. This and other similar programs are increasingly used to prevent reading difficulties and ensure that all children are reading at or above grade level by the end of third grade.…

The aim of this study is to investigate the effect of an educational agent, used in online task based learning media, and its form characteristics on problem solving ability perceptions of students. 2x2 factorial design is used in this study. The first study factor is the role of the educational agent and the second factor is form characteristics…

We report on a randomized controlled trial of Targeted Mental Health in Schools (TaMHS), which is a nationally mandated school-based mental health program in England. TaMHS aimed to improve mental health for students with, or at risk of, behavioral and emotional difficulties by providing evidence-informed interventions relating to closer working…

Early interventions aim at promoting a good mother-child relationship as basis for a good socio-emotional development, especially in high-risk populations, and at correcting already unfavorable patterns of interaction and are common today. Insecure attachment, both of the child and of the mother, has been identified as a risk factor for early…

The Common Core State Standards (CCSS) have been developed in response to the criticism that students in the U.S. are graduating from high school without being college and career ready and that they are falling behind their counterparts in other countries in key subject areas. In this work, the authors report the results of an efficacy study that…

Effectively grouping learners in an online environment is a highly useful task. However, datasets used in this task often have large numbers of attributes of disparate types and different scales, which traditional clustering approaches cannot handle effectively. Here, a unique dissimilarity measure based on the random forest, which handles the…

Background: Selective outcome and analysis reporting (SOR and SAR) occur when only a subset of outcomes measured and analyzed in a study is fully reported, and are an important source of potential bias. Key methodological issues: We describe what is known about the prevalence and effects of SOR and SAR in both randomized controlled trials (RCTs)…

Recent research on the design of social experiments has highlighted the effects of different design choices on research findings. Since experiments rarely collect their samples using random selection, in order to address these external validity problems and design choices, recent research has focused on two areas. The first area is on methods for…

Although evidence of negative associations between early literacy development and children's behavior problems exists, the field still lacks an understanding of the complicated links between these two areas. Children's gender has often not been included in much of the extant research as a potential moderating variable, yet gender differences may…

By 2013, all 50 states and the District of Columbia had adopted college- and career-ready standards in English language arts and mathematics, placing a greater emphasis on argument writing to prepare students for life after high school. Solving the specific problem of how to help teachers teach to new standards for argument writing as well as the…

Inquiry-based learning methods, coupled with advanced technology, hold promise for closing the science literacy gap for English learners (ELs) and students with learning difficulties (SWLDs). Project ESCOLAR (Etext Supports for Collaborative Online Learning and Academic Reading) created collaborative online learning units for middle school science…

The results of a large-scale randomized controlled trial of Conjoint Behavioral Consultation (CBC) on student outcomes and teacher-parent relationships in rural schools are presented. CBC is an indirect service delivery model that addresses concerns shared by teachers and parents about students. In the present study, the intervention was aimed at…

Objective: Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) A-criteria for ADHD were expanded to include new descriptors referencing adolescent and adult symptom manifestations. This study examines the effect of these changes on symptom endorsement in a sample of adolescents with ADHD (N = 259; age range = 10.72-16.70).…
