Accelerated Reader™ is a computerized supplementary reading program that provides guided reading instruction to students in grades K-12. It aims to improve students' reading skills through reading practice and by providing frequent feedback on students' progress to teachers. The Accelerated Reader™ program requires students to select and read a…

A major obstacle to developing evidenced-based policy is the difficulty of implementing randomized experiments to answer all causal questions of interest. When using a nonexperimental study, it is critical to assess how much the results could be affected by unmeasured confounding. We present a set of graphical and numeric tools to explore the…

School counselors are tasked with contributing to a safe and preventative school climate serving students' academic, career, and social/emotional needs through comprehensive school counseling program implementation. Positive Behavioral Interventions and Supports (PBIS) prioritizes a positive school climate, is widely implemented in the United…

In the study presented in this paper, we examined the possibility to scaffold mathematical modelling with strategies. The strategies were prompted using an instrument called "solution plan" as a scaffold. The effects of this step by step instrument on mathematical modelling competency and on self-reported strategies were tested using…

The experimental design was conducted to investigate the use of Microsoft Mathematics, free software made by Microsoft Corporation, in teaching and learning Calculus. This paper reports results from experimental study details on implementation of Microsoft Mathematics in Calculus, students' achievement and the effects of the use of Microsoft…

This study addresses the effectiveness of "Everyday Mathematics" (EM), a widely used core mathematics curriculum that reflects over two decades of National Science Foundation (NSF)-sponsored research and development studies (Klein, 2007; National Research Council, 2004) and aligns well with recommended policies and practices by the…

Butterfly Phonics aims to improve the reading of struggling pupils through phonics instruction and a formal teaching style where pupils sit at desks in rows facing the teacher. It is based on a course book created by Irina Tyk, and was delivered in this evaluation by Real Action, a charity based in London. Real Action staff recruited and trained…

Background: Confounding caused by selection bias is often a key difference between non-randomized studies (NRS) and randomized controlled trials (RCTs) of interventions. Key methodological issues: In this third paper of the series, we consider issues relating to the inclusion of NRS in systematic reviews on the effects of interventions. We discuss…

Young people from areas of socioeconomic disadvantage (SED) are more likely to present with language difficulties, particularly vocabulary difficulties. Studies have shown the effectiveness of vocabulary interventions for children with language impairment but not for adolescents from areas of SED. This article aims to establish the effectiveness…

The present study was part of a group randomized controlled trial in which 7th grade students were assigned to a yoga intervention or physical-education-as-usual. Sixteen students were randomly selected from the yoga condition to participate in one-on-one interviews. Qualitative analyses revealed 13 themes that were organized into two categories:…

We examined the relations between teachers' use of comments during book reading sessions in preschool classrooms and the vocabulary growth of children with low and moderately low language ability. Using data from a larger randomized controlled trial, we analyzed comments defined as utterances that give, explain, expand, or define. Comments were…

An emerging body of research examines language learning of young children from experiences with digital storybooks, but little is known about the ways in which specific components of digital storybooks, including interactive elements, may influence language learning. The purpose of the study was to examine the incidental word learning and story…

Using structural equation modeling, we examined the relationship of Hispanicism on recent substance use and whether Americanism moderated the effect in a sample of 1,141 Hispanic adolescents. The Bicultural Involvement Questionnaire (BIQ) was used to determine the degree of individual comfort in both Hispanic (Hispanicism) and American…

Teachers of elementary mathematics face multiple, convergent demands. These demands include supporting the growing population of English language learners (ELLs) and facilitating mathematical discussions across relevant curricular contexts. The authors used a comparative case study to examine how two teachers attempt to facilitate discussions…

In the 21st century, students have access to a plethora of information. As such, the skills required to access and effectively sort through this information (information literacy skills) become ever more important for success in both academic and non-academic settings. This study sought to assess the efficacy of two educational games designed to…
