The Irish language is a minority language undergoing the attenuation and accelerated change commonly seen as threatened languages come under increasing pressure from the dominant language. The decline of the numbers of traditional speakers and growing numbers of L2 speakers of Irish has given rise to some contested spaces regarding authenticity,…

Interventions for drug abuse and other maladaptive habitual behaviors may yield temporary success but are often fragile and relapse is common. This implies that current interventions do not erase or substantially modify the representations that support the underlying addictive behavior--that is, they do not cause true unlearning. One example of an…

This study had two aims. The first was to explain the process of using the Rasch measurement model to validate tests in an easy-to-understand way for those unfamiliar with the Rasch measurement model. The second was to validate two final exams with several shared items. The exams were given to two groups of students with slightly differing English…

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better…

Mobile technologies, specifically smartphones, offer social scientists a potentially powerful approach to examine the social world. They enable researchers to collect information that was previously unobservable or difficult to measure, expanding the realm of empirical investigation. For research that concerns resource-poor and hard-to-reach…

This article investigates 2 questions: (1) does the presence of background noise lead to a differential increase in the number of simultaneously activated candidate words in native and nonnative listening? And (2) do individual differences in listeners' cognitive and linguistic abilities explain the differential effect of background noise on…

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…
