This study examined the use, ethicality judgments, and perceived utility and accuracy of Online Machine Translators such as Google Translate by international students studying at a major university in the southeastern United States. These students were a part of a support program dedicated to international students enrolled in full content courses…

Collaborative learning has often been associated with the construction of a shared understanding of the situation at hand. The psycholinguistics mechanisms at work while establishing common grounds are the object of scientific controversy. We postulate that collaborative tasks require some level of mutual modelling, i.e. that each partner needs…

Purpose: We asked whether sentence repetition accuracy could be explained by interactions of participant processing limitations with the structures of the sentences. We also tested a prediction of the procedural deficit hypothesis (Ullman & Pierpont, 2005) that adjuncts are more difficult than arguments for individuals with developmental…

Learning experiences regarding the line of best fit are typically students' first encounters with the fundamental topic of statistical association. Students bring with them into these learning experiences prior knowledge and experiences about mathematical lines and their properties, namely slope. This study investigated the role students'…

In item response theory (IRT), the invariance property states that item parameter estimates are independent of the examinee sample, and examinee ability estimates are independent of the test items. While this property has long been established and understood by the measurement community for IRT models, the same cannot be said for diagnostic…

We assessed the effects of blocking on the accuracy of arranging visual stimuli in sequences as an attempt to assess whether verbal behavior mediates nonverbal performance. Across three experiments, college students were trained to echo and tact the names of abstract images vocally (Experiments 1 and 3) and with hand signs (Experiment 2), and…

Two new methods for the meta-analysis of factor loadings are introduced and evaluated by Monte Carlo simulations. The direct method pools each factor loading individually, whereas the indirect method synthesizes correlation matrices reproduced from factor loadings. The results of the two simulations demonstrated that the accuracy of…

The "familiarity effect" (Shen and Reingold, "Perception & Psychophysics" 63(3):464-475, 2001) is a phenomenon in which unfamiliar symbols perceptually "pop-out" when placed among familiar symbols (e.g., letters). In contrast, searching for familiar symbols among unfamiliar symbols is more challenging. Failure to…

This study attempted to investigate the impact of extensive reading (ER) on the writing ability of Iranian EFL students. The study also took a further step to explore the effect of adding group work activity to the extensive reading program to find its possible positive effect on improving writing ability. The present study had two experimental…

The axis of task research has shifted from task design to task planning, and rehearsal as a pre-task planning has been less touched upon throughout the history of the Second Language Acquisition (SLA); therefore, the current research was set around task rehearsal after Present-Practise-Product (PPP) model instruction in the task-supported language…

Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

This quasi-experimental study, using a pretest-treatment-posttest-delayed posttest design, investigated the effects of two comprehensive corrective feedback strategies: direct corrective feedback (DCF), and metalinguistic explanation (ME) on L2 learners' written syntactic accuracy. The participants were 90 Turkish EFL learners. After ensuring…

This study was designed to investigate the adequacy of EFL learners' abilities in three major dimensions of digital literacy skills and whether self-assessments of competence were consistent with their actual performance. It also identified factors that affected learners' use of the selected digital literacy skills. To this end, 60 Saudi EFL…

Automatic speech recognition (ASR) can be used to score oral reading fuency (ORF) assessments to ameliorate current inadequacies (e.g., administration errors, high opportunity cost), and represents an important part of a larger solution to improve traditional ORF. But more research is needed on how ASR performs for diverse student groups. The…

This Research Brief summarizes the performance of Miami-Dade County Public Schools (MDCPS) students participating in the International Baccalaureate (IB) program. The IB program was offered at six M-DCPS high schools in 2019-2020. Over 2,900 assessments were completed by M-DCPS students in 28 subject areas in 2019-2020. The number of IB…
