Demonstrating the differential effectiveness of instructional approaches for learners is difficult because learners differ on multiple dimensions. The present study tests a person-centered approach to investigating differential effectiveness, in this case of reading instruction. In N = 517 German third-grade students, latent profile analysis…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

The current study used the learning hierarchy/instructional hierarchy phases of acquisition and fluency to predict intervention effectiveness based on preintervention reading skills. Preintervention reading accuracy (percentage of words read correctly) and rate (number of words read correctly per minute) were assessed for 49 second- and…

The current pilot study demonstrates the potential of adding simple and efficient bully prevention strategies to already established School-Wide Positive Behavior Interventions and Supports. The self-report surveys of third-, fourth-, and fifth-grade students from three elementary schools evaluated the relationship between the implementation of…

Two quasi-experimental field studies (N = 419; 248) tested the effects of an outdoor environmental education program based in local Protected Natural Areas (PNAs) on 3rd-to-6th-grade students' proenvironmental attitudes and behaviors. Results show the program increases children's place attachment, proenvironmental attitudes, ethics and…

Children practice their spatial skills when playing with spatial toys, such as construction materials, board games, and puzzles. Sex and SES differences are observed in the engagement in such spatial play activities at home, which relate to individual differences in spatial performance. The current study investigated the effects of explicitly…

We evaluated the effects of a summer reading intervention with a sample of low-income Black and Hispanic students who were struggling readers. In the summer before their 2nd- or 3rd-grade school year, 14 rising 2nd graders and 18 rising 3rd graders received 15 hr of a scripted, explicit phonics-based program in dyads from credentialed elementary…

Objective: The objective of this study was to investigate the relationship between classroom psychological climate and the physical and sedentary behaviour of primary school students after the implementation of an innovative education programme regarding nutrition and physical activity. Design: Randomised controlled trial. Setting: Study…

In this study, we present quantitative findings on the effects of English-Spanish dual language immersion on student achievement in science and mathematics in grades 3, 4, and 5. The research aims to present empirical evidence documenting the impact of dual language immersion, reveal analytical techniques utilizing nonparametric measure of similar…

Classroom physical activity (PA) has been linked to a multitude of health and academic benefits. However, due to barriers such as lack of time and resources many teachers are not implementing classroom PA to the degree they would like to. One innovative solution is to integrate classroom PA into academic concepts. Based on self-determination…

In this paper, we provide evidence of the impact of early algebra (EA) over time. We document this impact in the following ways: (a) by showing the performance over time of an experimental group of 15 children on an algebra assessment, from 3rd to 5th grade; and (b) by showing how the performance on an algebra assessment of children from an…

This study investigated the role of strategy instruction and working memory capacity (WMC) on word problem solving accuracy in children with (n = 100) and without (n = 92) math difficulties (MD). Within classrooms, children in Grades 2 and 3 were randomly assigned to one of four treatment conditions: verbal-only strategies (e.g., underlining…

The longitudinal intervention study reported here is the first to investigate the efficiency of computer learning software specifically designed for dyslexic Swiss German learners of Standard German as a second language (L2) and English as a third language (L3). A total of 40 subjects (20 of them dyslexics and 20 of them nondyslexics; 10 students…

Reading comprehension, defined as the active extraction and construction of meaning from all kinds of text, requires children to fluently decode and understand what they are reading. Basic processes underlying reading comprehension are complex and call on the oral language system and a conscious understanding of this system, i.e., metalinguistic…
