Recently, researchers have concluded that motor skill performance is enhanced when learners adopt an external attentional focus, compared to adopting an internal focus. We extended the line of inquiry to children and examined if skill learning in children was differentially affected by providing instructions and feedback that direct attentional…

The current study meta-analyzed 47 single-subject studies of behavioral self-management interventions that were published between 1971 and 2011. In addition to obtaining an overall measure of effect across all self-management studies (f = 0.93), analyses were conducted to assess whether treatment effectiveness was moderated by factors such as…

Collaborative text reconstruction tasks such as dictogloss have been suggested as effective second language (L2) learning tasks that promote meaningful interaction between learners and their awareness of L2 target grammatical structures. However, it should be noted that the effect of pair interaction on the final product may differ depending on…

The aim of this study is to determine variance difference between maximum likelihood and expected A posteriori estimation methods viewed from number of test items of aptitude test. The variance presents an accuracy generated by both maximum likelihood and Bayes estimation methods. The test consists of three subtests, each with 40 multiple-choice…

The purpose of this study was to explore the effect of task demands on children's singing accuracy. A 2 × 4 factorial design was used to examine the performance of fourth-grade children (N = 120) in solo and doubled response conditions. Each child sang four task types: single pitch, interval, pattern, and the song "Jingle Bells." The…

Background: In the last decades, children's understanding of mathematical principles has become an important research topic. Different from the commutativity and inversion principles, only few studies have focused on children's understanding of the addition/subtraction complement principle (if a - b = c, then c + b = a), mainly relying on verbal…

Research has consistently shown diversity of vocabulary to be an important indicator of second language (L2) writing development as well as L2 writing performance. These studies underscore the importance of vocabulary to L2 writing. However, they provide little to indicate what kind of vocabulary learners of English may need to know in order to…

The purpose of this research project was designed to test the hypothesis that students taking part in this study would increase their reading comprehension and reading fluency skills by taking part in the Daily 5 Model and The CAFÉ System during the literacy block. The researcher sought to answer the question, "What impact do The Daily 5…

The purpose of this study is to provide a theoretical explanation for the effectiveness of Written Corrective Feedback (WCF) in increasing second-language (L2) students' grammatical accuracy. WCF is examined via Skill Acquisition Theory (SAT) in order to account for uneven patterns of its effectiveness. As the study demonstrates, WCF is effective…

To succeed in STEM, students need to learn to use visual representations. Most prior research has focused on conceptual knowledge about visual representations that is acquired via verbally mediated forms of learning. However, students also need perceptual fluency: the ability to rapidly and effortlessly translate among representations. Perceptual…

The aim of this experimental study is to examine the development of gender assignment and gender agreement in bilingual Albanian-Greek and English-Greek children as well as the exploitation of gender cues on the noun ending in real and pseudo-nouns. Four gender tasks were designed, two targeting gender assignment (determiner + noun production) and…

This study aims to design and implement a speaking task model following the principles of Task-Based Language Teaching (TBLT) and Critical Thinking (CT). The study mainly investigated to what extent the use of critical thinking standards had an impact on the students' oral performance with respect to the linguistic trilogy of fluency, accuracy,…

This Kindergarten Teacher's Guide provides information for kindergarten teachers on how to support families as they practice foundational reading skills at home. It serves as a companion to the What Works Clearinghouse (WWC) Foundational Skills to Support Reading for Understanding in Kindergarten Through 3rd Grade. Both guides present four…

This article introduces three important challenges and possible solutions when using spoken dialogue to measure the use of specific multiword expressions. The first challenge is deciding whether to count precise and accurate use of target expressions only or whether to extend the count to include variation. The second challenge requires addressing…

In the present study, we investigated developmental trajectories of alerting, orienting, and executive attention networks and their interactions over childhood. Two cross-sectional experiments were conducted with different samples of 6-to 12-year-old children using modified versions of the attention network task (ANT). In Experiment 1 (N = 106),…
