The Latino English Language Learner population continues to rise each year in our schools, currently accounting for over 10% of all K-12 students in the United States (Cheung, 2019). Even with this growth in population, Latinos continue to lag behind other races in academic attainment and advancement in postsecondary success (NCES, 2019). This…

This study examined the differences and similarities among the writing of three types of developmental English and advanced ESL United States community college students, comparing the writing of resident English learners (RL2), whose home language was not English but who attended United States public schools for five years or more, to that of…

Speaking in a foreign/second language is a challenge for many learners, even when they have linguistic knowledge. Drawing on González-Lloret and Ortega's (2014) framework for technology-mediated tasks and MacIntyre's (2007) framework for willingness to communicate in a second language, this mixed methods study investigated the impact of…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

Instructional explanations are an ubiquitous component of classroom instruction, but are relatively neglected in science education when compared to other facets of teaching and learning. The ubiquity of instructional explanations and their potential to stimulate learning in students suggests that they should garner more attention from science…

This dissertation explored the effect of Gagne's nine events of instruction on student academic achievement and satisfaction during an online English class for French speakers. A group of 30 Facebook users from French-speaking countries in North and Sub-Saharan Africa participated in the research. They were divided randomly into two groups: one…

Purpose: Our study addresses three main questions: (a) Do autistics and neurotypicals produce different patterns of disfluencies, depending on the experimenter's direct versus averted gaze? (b) Are these patterns correlated to gender, skin conductance responses, fixations on the experimenter's face, alexithymia, or social anxiety scores? Lastly,…

This study analyzes Chinese, Spanish, English, Thai, Japanese, Korean, French and German speakers' motivation to teach their first language as a foreign language (FL) online without being trained as a second language teacher (SLT) and compares them with professionally trained SLTs. The threshold for starting SLT without teacher certification in…

Middle school teachers frequently struggle with positively managing student behavior. However, praise-to-reprimand ratios (PRRs) have received little research attention. PRRs studied in elementary school have been positively associated with improvements in on-task and prosocial behavior, but limited research has been conducted on optimal PRRs in…

This report leverages state educational agency data to explore the association between Alabama Science in Motion (ASIM) implementation and student outcomes. We conducted this study in Alabama to evaluate the potential of teacher implementation of ASIM lab activities to improve high school level student achievement in science. This study follows a…

The present study investigated the efficacy of segmental/suprasegmental vs. holistic pronunciation instruction in the development of listening comprehension skills by EFL learners, using a pre-test post-test design. Six groups of 20 intermediate EFL learners at a university in Iran took part in the study, all groups receiving the same amount of…

This dissertation focused on comparing the academic achievement and language proficiency in both English and Spanish of students at risk for language and learning difficulties, with bilingual typically developing students in two bilingual educational contexts: English as a Second Language program and Spanish two-way immersion program.

This study examined the effects of three subtitle conditions on English vocabulary learning, form recognition and meaning recall, from TED Talks videos while controlling for vocabulary size and initial knowledge of the target words. The participants, 105 Libyan students (16 males and 89 females) at intermediate English proficiency level, were…

This paper demonstrated how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. Using a data-driven approach, we examined: (1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance (i.e. posttest math knowledge scores) prediction; and…

This study explored how a revised on-campus occupational therapy clinic model impacted occupational therapy graduate student professional development and clinical practice educator confidence in areas related to the on-campus clinic environment, professionalism, student learning, and collaboration. Specifically, clinical practice educator and…
