The purpose of this study was to evaluate the internal consistency reliability, validity, and diagnostic accuracy of Social, Academic, and "Emotional Behavior Risk Screener--Teacher Rating Scale" (SAEBRS) scores. Teachers (n = 68) universally screened 1,242 elementary students using two measures: the SAEBRS and the "Behavioral and…

Investigating the effects of task design and implementation features on second language (L2) production is necessary, as the findings can provide potential insights into pedagogical and assessment task design and sequencing as well as into the nature of L2 learners' attentional resources. To this end, this study probed into the effects of task…

Purpose: The function of child-directed speech has been debated for decades. This study examined the perceptual and acoustic characteristics of child- and adult-directed Cantonese tones to test the hyperarticulation and prosodic hypotheses that have been proposed to account for the acoustic modifications in child-directed speech. Method: Sixty-two…

Purpose: The current study aimed to compare traditional logistic regression models with machine learning algorithms to investigate the predictive ability of (a) communication performance at 3 years old on language outcomes at 10 years old and (b) broader developmental skills (motor, social, and adaptive) at 3 years old on language outcomes at 10…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

To date, applying what is known about child development to educational app design has been minimally studied and rarely tested. Using developmental and learning sciences research (e.g., Hirsh-Pasek et al., 2015), this dissertation identifies whether evidence-based teaching strategies are used in the design of existing educational apps and…

This resource, released in collaboration with the Center for the Analysis of Postsecondary Readiness, explains the importance of developmental education, its current challenges and how policymakers can contribute to improving outcomes.

Identifying at-risk students as soon as possible is a challenge in educational institutions. Decreasing the time lag between identification and real at-risk state may significantly reduce the risk of failure or disengage. In small courses, their identification is relatively easy, but it is impractical on larger ones. Current Learning Management…

As a second-year English teacher at Nakhonphanom University, it has become important to put more emphasis on the student's ability to understand and speak the English language. The main objective as a teacher is to help the students learn the English language by utilizing the best methods. Thailand is rapidly becoming part of the global economy…

We report on a study investigating the influence of context, direction of translation, and function type on undergraduate students' ability to translate between graphical and symbolic representations of mathematical relations. Students from an algebra-based and a calculus-based physics course were asked to solve multiple-choice items in which they…

The ELO-L (Évaluation du langage oral chez l'enfant libanais) is the first norm-referenced language-screening test in Lebanon. It is an adaptation of the ELO, a French language-screening test. The ELO-L was normed on 1,718 children aged three to eight years and divided into eight age groups with a minimum of 100 participants in each group. It is…

This study examined whether social bias manipulation can influence how naïve multiage listeners evaluate second language (L2) speech. Sixty native English-speaking listeners (Montreal residents) rated audio recordings of 40 Quebec French speakers of L2 English for five dimensions of oral performance (accentedness, comprehensibility, segmental…

This study adopted the between-subjects and within-subjects group designs to examine the impact of visual aids on 26 intermediate Chinese as a Foreign Language (CFL) learners' reading comprehension in an American college. Students were assigned into two groups to complete multiple-choice and translation tasks to test effects of visual aids. The…

This article explores what kind of second language (L2) input influences Japanese learners' acquisition of adjective ordering restrictions (AOR) in English where Japanese exhibits no AOR. In Study I, an explicit instruction (EI) group (n = 13) and a natural exposure (NE) group (n = 12) responded to a preference task. In Study II, an input flood…

This dissertation reports the results of a research project that examined the effects of varying rates of reinforcement on students' math performance and assignment preference. The relationship between students' instructional level and the rate of reinforcement threshold for influencing assignment preference was also explored. Participants were…
