Four classes of first-grade children at a Christian school took pre- and post-tests measuring humility. Two intervention classes had devotional lessons on humility and two comparison classes did not. For one week, devotional lessons featured humility-related children's literature, cognitively appropriate discussions, writing about humility, and…

The study aimed to explore how weight changes from childhood to adolescence influenced the performances of physical fitness. The participants (N = 115) were pre-tested when they were in kindergarten, first, or second grades (mean age = 7.25). The same participants were post-tested again after 6 years. The President's Challenge test battery was…

Though the immediate effect of Reading Recovery (RR) is both strong and well established, the longer term or sustained effect has been less studied and the evidence regarding it has been less conclusive. Michigan Reading Recovery students (n = 328) were compared to control students (n = 264) while in first (2009-2010), third (2011), and fourth…

Executive functions (EF) can be promoted by classroom interventions. Our study investigated whether (a) an intervention conducted by teachers improves EF in children; (b) there are effects on behaviour and academic achievement; and (c) there are stable benefits in a one-year follow-up. Fifty-eight first-graders, divided into experimental (EG = 28)…

Although substantial research indicates motivation contributes significant variance to reading comprehension in upper elementary students, research with students in primary grades has focused, instead, on the relation of motivation to word reading. Assessment of reading motivation in 68 first and second graders indicated word and nonword reading…

The purpose of this study was to compare the results of a regression discontinuity design (RDD) with those of an experimental design of a tiered vocabulary intervention for children at risk for reading disability to determine RDD's feasibility as a research methodology for this type of study. Researchers reanalyzed an archival dataset of a…

The ability to flexibly approach the pronunciation of unknown words, or set "for variability", has been shown to contribute to word recognition skills. However, this is the first study that has attempted to teach students strategies for increasing their set for variability. Beginning readers (N = 15) were instructed to correct oral…

Introduction: In the present study we used a metaphorical representation in order to stimulate the numerical competences of six-year-olds. It was expected that when properties of physical action are used for mathematical thinking or when abstract mathematical thinking is grounded in sensorimotor processes, learning gains should be more pronounced…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Vocabulary knowledge at school entry is a robust predictor of later reading achievement. Many children begin formal reading instruction at a significant disadvantage due to low levels of vocabulary. Until recently, relatively few research studies examined the efficacy of vocabulary interventions for children in the early primary grades (e.g.,…

This study examined the effect of improvements in timing/rhythmicity on students' reading achievement. 86 participants completed pre- and post-test measures of reading achievement (i.e., Woodcock-Johnson III, Comprehensive Test of Phonological Processing, Test of Word Reading Efficiency, and Test of Silent Word Reading Fluency). Students in the…
