Sleep deprivation impairs a wide range of cognitive processes, but the precise mechanism underlying these deficits is unclear. One prominent proposal is that sleep deprivation impairs vigilant attention, and that impairments in vigilant attention cause impairments in cognitive tasks that require attention. Here, we test this theory by studying the…

This study aims to analyze the types, and frequency of errors in written sentences by undergraduate Saudi English as a Foreign Language (EFL) learners, following a quasi-experimental design. Data were collected from two groups: the control group (CG) and the experimental group (EG) through written sentences. The control group (CG) did not receive…

Developing effective oral business English (OBE) curricula requires clearly understanding student needs. This study evaluated the speaking needs of Chinese English as a Foreign Language (EFL) undergraduates majoring in business English for specific purposes (ESP), aiming to inform the design of a teaching module that bridges the gap between…

This study investigated the erroneous use of the high-frequency verb TAKE by the Chinese college learners of English as a foreign language (EFL), aiming to identify the similarities and differences between Chinese EFL learners, aimed at finding out more effective ways for the teaching and researching of the high-frequency verbs. Corpus-based…

We developed an online learning module called ''Organic Mechanisms: Mastering the Arrows'' to help students learn part of organic chemistry's language--the electron-pushing formalism. The module guides students to learn and practice the electron-pushing formalism using a combination of interactive videos, questions with instant feedback, and…

While recent literature has focused extensively on the widely embraced approach of explicit instruction, there is a considerable paucity of research concerning plausible practical frameworks that can demonstrate how such particular approach is implementable in EFL classes. To address the specific writing deficiencies of EFL students, the current…

Formative assessments and feedback are vital to enhancing learning outcomes but require that learners feel at ease identifying their errors, and receiving feedback from a trusted source--teachers. An experimental test of a new theoretical framework was conducted to cultivate a pedagogical alliance to enhance students' (a) trust in the teacher, (b)…

The impact of baseline trend control on visual analyses of AB intervention graphs was examined with simulated data at various values of baseline trend, autocorrelation, and effect size. Participants included 202 undergraduate students with minimal training in visual analysis and 10 graduate students and faculty with more training and experience in…

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of…
