This study examines how Science, Technology, Engineering, and Mathematics (STEM) Education may improve English Language Learners' academic achievement and high school graduation. In particular, it highlights the plight faced by ELLs in high schools regarding quality education that allows them to graduate on time and attend college. The analysis…

In two experiments (N = 64), we told 6- to 7-year-olds about improbable or impossible outcomes (Experiment 1) and about impossible outcomes concerning ordinary or magical agents (Experiment 2). In both experiments, children claimed that the outcomes were impossible and could not happen, but nonetheless generated realistic and natural explanations…

Learners style is grouped into four types mainly; Visual, auditory, kinesthetic and Read/Write. Each type of learners learns primarily through one of the main receiving senses, visual, listening, or by doing. Learner style has an effect on the learning process and learner's achievement. It is better to select suitable learning tool for the learner…

Purpose: Studying the variations in speech levels with changing background noise level and talker-to-listener distance for talkers wearing hearing protection devices (HPDs) can aid in understanding communication in background noise. Method: Speech was recorded using an intra-aural HPD from 12 different talkers at 5 different distances in 3…

This study aimed to study the association between diglossic reading skills and reading comprehension in first grade students with and without learning disabilities. In this study population, students presented diglossia in literary and colloquial Arabic: 30 first grade students with learning disabilities and 30 first grade students without…

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,…

Reading self-beliefs, comprising self-concept and self-efficacy, play a pivotal role in shaping students' learning engagement and learning outcomes. However, existing literature on the self-beliefs of school-entry students primarily originates from Western contexts, and the exploration of differences in self-beliefs, engagement in learning, and…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

The literacy instruction that adolescent emergent bilingual (EB) students currently receive is insufficient to improve their writing proficiency (Graham et al., 2021; National Center for Education Statistics, 2012). To promote improvements in EBs' writing, evidence-based practices that are culturally and linguistically responsive must be provided…

There is a tradeoff between scale length and psychometric concerns. The two are, in fact, directly linked. Generally, when scales are shortened, reliability is reduced, and when scales are lengthened, reliability is improved, provided the items added to the scale are comparable psychometrically (AERA et al., 2014). Scale reliability, in turn,…

The "Lau v. Nichols" Supreme Court case specifies two core responsibilities of schools -- and rights for students -- with regard to students classified as English learners (ELs): 1) opportunities to learn English; and 2) equitable access to grade-level content. Yet 50 years since Lau's passage, students' right to content may not be being…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

This study aimed to examine Chinese college students' engagement and satisfaction with their university learning experience. In particular, the study focused on emotional engagement and how it was associated with student satisfaction. Nationally representative data from the 2012 China College Student Survey (CCSS) which drew from 55 higher…

Objective: While cigarette smoking in the United States has declined, the age range of smoking initiation has risen to include young adults. This study investigated the relationship of Theory of Planned Behavior constructs (TPB; attitudes, subjective norms, and perceived behavioral control [PBC]) to nonsmoking intention among college students.…
