Increasing productivity in educational systems is of great importance. Researchers are keen to predict the academic performance of students; this is done to enhance the overall productivity of educational system by effectively identifying students whose performance is below average. This universal concern has been combined with data science…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

Multidimensional item response theory (MIRT) models have generated increasing interest in the psychometrics literature. Efficient approaches for estimating MIRT models with dichotomous responses have been developed, but constructing an equally efficient and robust algorithm for polytomous models has received limited attention. To address this gap,…

Purpose: High-variability phonetic training (HVPT) has been found to be effective on adult second language (L2) learning, but results are mixed in regards to the benefit of multiple talkers over single talker. This study provides a systematic review with meta-analysis to investigate the talker variability effect in nonnative phonetic learning and…

Scoring language learners' speaking skills is open to a number of measurement errors since raters' personal judgements could involve in the process. Different grading designs in which raters score a student's whole speaking skills or a specific dimension of the speaking performance could be settled to control and minimize the amount of the error…

This study investigated the effectiveness of inquiry-based learning (IBL) approach in ratio and proportion on the mathematics reasoning skill of seventh-grade students. The study was carried out in a seventh-grade mathematics course in a middle school located in the Central Anatolia region of Turkey during the 2016-2017 academic year. The IBL…

Individuals with autism spectrum disorder (ASD) experience challenges maintaining fluid, reciprocal conversations, resulting in prolonged, awkward pauses. Such pauses disrupt the pacing of an interaction and create: (1) less favorable social impressions; and (2) perceptions of limited social competence. To help these individuals succeed socially,…

The growing diversity and uptake of social media has increased the sources of health information available to young people. YouTube is one of the most popular social media platforms for young people in the United Kingdom, and YouTubers are the most important influencers on the platform producing diverse health content. They are increasingly…

The purpose of this systematic review was to characterize the implementation of reliability generalization meta-analytic (RGM) practices within mathematics education-related empirical research. RGM studies are used to investigate and generalize the reliability of a measure across various studies. An exhaustive literature search was conducted to…

Verbal praise is frequently used as motivation by teachers in class and truly effective verbal praise plays an important role in maintaining classroom order and stimulating positive student behavior. In this study, students from three classes of X Primary School of Jiangxi Province were interviewed and 328 verbal praise expressions collected. The…

In this article, first we obtained the correct mean square error expression of Gupta and Shabbir's linear weighted estimator of the ratio of two population proportions. Later we suggested the general class of ratio estimators of two population proportions. The usual ratio estimator, Wynn-type estimator, Singh, Singh, and Kaur difference-type…

Purpose: This tutorial summarizes current best practices in treating American English /r/ distortions in children with residual speech errors. Method: To enhance the effectiveness of clinicians' cueing and feedback, the phonetics of /r/ production is reviewed. Principles of acquisition, which can inform how to practice /r/ in the early stages of…

Young children who cannot use their natural speech to communicate their daily wants, needs, thoughts, and opinions often rely on augmentative and alternative communication (AAC) strategies that frequently use graphic symbols to assemble messages. Early intervention strategies typically focus on visual scene displays (VSDs) to place target messages…

This RCT study examined efficacy of a preschool peer social intervention (PPSI) in facilitating social engagement of preschoolers with high-functioning ASD (HFASD; N = 65). HFASD participants were randomly assigned by preschool to a 6-month intervention (play, interaction, or conversation) or a waitlisted-treatment-as-usual control group. Trained…

Background: Acquisition and generalization of data analysis skills are perennial challenges for psychology students. Teaching advanced data analysis in a psychology-specific context might improve students' learning. Objective: At a mid-sized public university, we evaluated student outcomes after a new quantitative psychology course taught in the…
