Recent data have shown that only 34% of eighth graders and 37% of 12th graders were reading at or above proficiency (NAEP, 2015). A total of 21% of Hispanic eighth graders were reading at or above proficiency, and only 25% of Hispanic 12th graders were reading at or above proficiency. Of African-American students, 16% of eighth graders and 17% of 12th graders were reading at or above proficiency. In order for adolescents to become successful and productive adults, they need to acquire advanced literacy skills. Many of these demands require an education beyond high school (Rothman, 2012). Concern for English learners (EL) is even more warranted due to the fact that they represent the fastest growing school-age population in the United States and tend to exhibit lower academic achievement than their non-EL peers (Matthews & Ewen, 2006; National Clearinghouse for English Language Acquisition [NCELA], 2006; Padolsky, 2005; Thomas & Collier, 2001; Klingner, Artiles, & Barletta, 2006). To address this issue, the present study was conducted to examine the effects of a Vocabulary Scenario Technique English Learner Peer Protocol (VST-ELP) with ninth-grade English learners (ELs) who were struggling with literacy. The technique's purpose was to increase students' vocabulary in order to improve their listening, speaking, reading, and writing skills. The study employed an experimental design, specifically a pre-test/post-test comparison group design with a total of 34 participating students and one classroom teacher. The study was conducted over four weeks with six hours of intervention. An analysis of variance revealed that there was an increase in mean scores from pre to post in the experimental group on both the synonym and sentence tests. Findings suggest that the Vocabulary Scenario Technique English Learner Peer Protocol (VST-ELP) was effective with ninth-grade EL students who were struggling with literacy. Clinical implications and future research directions were discussed.

Reading attitude plays a vital role in the academic achievement of students. This thesis reports findings from a study of how parents' reading attitudes and habits may influence their children's reading attitudes and habits. Students and parents attending a metropolitan university's Saturday Reading Camp (SRC) in the United States participated in this study. Participants completed a survey that examined participants' reading attitudes and habits. Results from this study showed minor similarities between the reading attitudes of parents and their children. However, there were more significant similarities between the reading habits of parents and their children.

The motivation to read plays a key role in any student's reading development and success. In the context of 21st century literacies and learning, students engage in reading with print and digital texts and read in traditional and multimodal settings. This situated thesis explored the topic of second grade students' motivation to read through the lens of reading performance and time spent reading and improving their reading skills using i-Ready. Fourteen second grade students in a Central Florida elementary school classroom received the Motivation to Read Profile- Revised (MRP-R) (2013), an established survey, that is designed to gauge elementary school age students' motivation to read. In addition, the researcher selected the top 25% students who showed progress in reading using i-Ready results from Diagnostic 1 and Diagnostic 2 and conducted one informal conversation interview about their motivation to read. The MRP-R (2013) data was analyzed using elementary statistics in the areas of reader self-concept and value of reading. The informal conversational interview data was analyzed in terms of themes in the area of value of reading—i.e., other sources/books students like to read, if they like to read electronic sources or print ones, and what they read when they use the Internet. In summary, this study may guide myself as a teacher, and potentially other teachers, to make connections between what students are motivated to read and selecting text(s) for them to read when on i-Ready. The ultimate value of this study lies in guiding teacher instruction and decisions to maximize student motivation to read. The results from this study showed that the group that spent the most time was more positively motivated to read than the remaining second graders. However, the group that showed the most growth was not more or less motivated to read.

In this descriptive linguistic study, the lexico-grammatical complexity of placement and exit English for Academic Purposes (EAP) student writing samples was analyzed using corpus linguistic methods to explore language development as a result of student enrollment in the EAP program. Writing samples were typed, matched, and tagged. A concordance software was used to produce lexical realizations of grammatical features. A comparison was made of normed frequency counts for nine phrasal and clausal features as well as raw frequencies for type to token ratio (TTR), average word length, and word count. In addition, the contribution of variables such as advanced grammar and writing course grades, LOEP scores, and the number of semesters in the EAP program to the English Learner's (EL) lexico-grammatical complexity found in exit essays was also examined. Twelve paired parametric and non-parametric analyses of lexico-grammatical variables were performed. Dependent t test results showed that normed frequency counts for such features as pre-modifying nouns, attributive adjectives, adverbial conjunctions, coordinating conjunctions, TTR, average word length, and word count changed significantly, and students produced more of those features in their exit writing than in their placement essay. Non-parametric Wilcoxon test indicated that such a change was also observable with noun + that clauses. The frequencies of verb + that clauses and subordinating conjunction because, though non-significant, actually decreased. A split plot ANOVA allowed to see whether a change in above mentioned statistically significant lexico-grammatical features could be attributed to grammar instruction in EAP 1560. The results showed that there was no statistically significant difference between those who took EAP 1560 class and those who did not on pre-modifying nouns, coordinating conjunctions, TTR, average word length, and word count. On the other hand, those students who did not take EAP 1560 class had higher counts of attributive adjectives but lower of adverbial conjunctions, both statistically significant results, than those students who took the class. Lastly, five multiple linear regression analyses were conducted to predict frequencies of exit pre-modifying nouns, attributive adjectives, noun + that clauses, adverbial conjunctions, and TTR from EAP 1560 and EAP 1640 grades, LOEP scores, and the number of semesters students spent in the EAP program at SSC. The only significant regression analysis was with TTR, and 28% of its variance could be explained by the independent variables. LOEP Language Usage score was the only significant individual contributor to the model. Even though exit adverbial conjunctions were not predictable from the chosen IVs, LOEP Sentence Meaning score proved the only significant contributor to that model. The results indicate that compressed phrasal features are indicative of higher complexity and EL proficiency, while clausal features are acquired earlier and signal elaboration, as previously described in the literature.

The current study identifies and discusses the adjustment challenges facing Arabian Gulf Students (AGSs) that may affect their English performance (EP) in intensive English programs (IEPs) in the United States. The current study uses student departure theory to lead the theoretical framework and incorporates Student Adaptation to College Questionnaire (SACQ) and Social Integration Questionnaire (SIQ) to lead the methodology of this study. The mixed-method investigation with multi-location sampling examined 160 AGSs, enrolled full-time in different IEPs in the U.S. during the spring semester of 2019. The AGSs participants were from Iraq, Kuwait, Saudi Arabia, Qatar, Bahrain, the United Arab Emirates, and Oman. A pilot study preceded the final study to obtain AGSs' insight on the questionnaire items and time consumption. In the final study, the participating students completed a demographic information questionnaire as well as the SACQ and SIQ for the quantitative segment of this study. Face-to-face and Skype interviews followed as the qualitative segment of the proposed study. Data analyses included several methods. The questionnaire results were analyzed by inputting data into IBM Statistics Package for Social Sciences (SPSS) Statistics. The interview responses were analyzed within a phenomenological approach by finding common themes within the interview responses. The findings shed light on the needs and means of helping AGSs succeed in achieving high levels of English proficiency in IEPs in the U.S.

The purpose of this study was to investigate the impact of an intervention on teaching science as argument within a science methods course on elementary preservice teachers' (PSTs') (a) understandings of the nature of science (NOS), (b) knowledge about argumentation, (c) complexity of their written explanations, and (d) ability to incorporate components of the framework for teaching science as argument to support students' literacy and science learning. This mixed-methods study utilized an embedded quasi-experimental design with a treatment (n = 20) and control group (n = 25). The treatment group instructor, who completed an eight-week professional development course, implemented the intervention protocol across a 12-week period. Throughout the intervention, emphasis was placed on three key components of teaching science as argument (i.e., argument structure, public reasoning, and the language of science). The control group instructor, who did not partake in any professional learning activities, implemented business-as-usual instruction. Results from a repeated measures MANOVA revealed that, although the intervention did not have a significant impact on PSTs' knowledge of argumentation, PSTs who received the intervention did demonstrate a significant increase in their understanding of the NOS and in the complexity of their written explanations, as compared to PSTs who did not receive the intervention. Furthermore, analysis of PSTs' written lesson plans revealed several themes (i.e., opportunities for students to collect and analyze data, use of scaffolds for helping students construct scientific explanations, emphasis on the use of text to support scientific inquiry, and attention to developing students' science vocabulary) consistent with the framework for teaching science as argument. These findings contribute to a growing body of evidence illustrating the effectiveness of intentionally designed teacher preparation experiences for developing PSTs' knowledge, beliefs, and practices for supporting students' engagement in scientific explanation and argument.

The present study, a corpus-based quantitative analysis, investigated the use of passive voice in terms of percentage (percentage of total passive usage), constructions (the most commonly used passive forms), and dispersion (the verbs that tended to be associated with passive usage) in college STEM textbooks, more specifically in Science, Technology, Engineering, and Mathematics. The corpus consisted of twenty textbooks with over 1 million running words selected from the textbooks' chapters. By identifying the main verbs and passive verbs used in the textbooks, the percentage of passive voice usage was calculated. The statistical difference of passive constructions between disciplines was examined by conducting a MANOVA test, and an instrument, the Compleat Lexical Tutor was used to generate a word list of the most commonly-used past participles in passive voice. Results showed that the overall percentage of passive voice usage is over 30%. The MANOVA test revealed a statistically significant difference of passive voice constructions across the four disciplines, i.e. Science, Technology, Engineering, and Mathematics. Implications for teaching suggest that passive voice was an important grammar feature that needs to be taught tor the English as a second/foreign language students who major in the STEM fields. Additionally, the use of passive constructions should be taught differently in reading and writing based on the needs of the four STEM disciplines, due to the significant difference of passive forms usage in these fields.

Drawing on the poststructuralist construct of identity and on Norton's (1995) concept of investment, as well as on Bourdieu's (1977) notion of capital, this qualitative research study relies on data gathered through interviews conducted with two adult female participants from Puerto Rico, who migrated to Central Florida approximately ten years ago. It aims at answering the following questions: (i) what identity-related factors facilitate or hinder the acquisition of the target language by Puerto Rican migrants? (ii) what social forces or barriers impact learning ESL in the context of Puerto Rican migration to the United States? The findings indicate that investment in social and academic practices can benefit students who want to learn the target language, but power inequities in interactions between native speakers and migrants can prevent the latter from interacting in the English-speaking community, making it difficult to acquire the language. The findings may serve to encourage further studies in second language and identity.

This critical policy analysis and collective case study, informed by ethnographic techniques, involved reviews of twelve Florida school district ESOL policies (included within the 2016-2019 District English Language Learner Plans, required of all Florida districts to complete) whose English learner (EL) populations met or exceeded ten percent (10%) of their total enrollment. A priori coding of these policy documents was conducted using nine criteria pulled from the literature on culturally responsive practice (CRP), which served as the theoretical framework for the study. Subsequent observations and practitioner interviews within two schools from the same district were conducted in order to ascertain how practice seemed to align with policy, how these practices differed from site to site despite their location within the same district, and ultimately to assess the efficacy of observed pedagogical and administrative practices within the theoretical framework of CRP. Results were mixed and indicated a lack of consistency across the board in terms of policy, implementation, and culturally responsive practice.

Built upon the Contrastive Interlanguage Analysis (CIA) framework, this corpus-based research analyzes three lexical features (lexical diversity, lexical sophistication, and cohesion) in native and nonnative English writers' academic writing and examines the potential differences in lexical performance 1) between native and nonnative English writers and 2) across all writers from various language backgrounds. The differences in lexical performance in academic writing between native and nonnative English writers and the unique characteristics of writers from different language backgrounds suggest the necessity of targeted academic writing instruction based upon learner needs. Using text length as the covariate, two Multivariate Analysis of Covariate (MANCOVA) were conducted with language background as the Independent Variable and the three lexical features as the Dependent Variables. The results revealed that nonnative English writers demonstrated significantly lower performance in lexical sophistication than did native English writers. In terms of the comparison between writers from different language backgrounds, the results suggested statistically significant differences in all three aspects of lexical features. Pedagogical implications for vocabulary instruction in academic writing for nonnative English writers include emphasizing the mastery of academic, low-frequency, and discipline-specific vocabulary. In addition, improving nonnative writers' vocabulary size and lexical diversity can offer these learners more options to build cohesion in academic writing at a deeper level. Moreover, the results of this study highlight the wide but often under-considered variability within any language group as individual learner differences come into play, thereby downplaying the idea that writers of any given language tend to perform homogenously. Instructors should acknowledge the unique writing characteristics of different nonnative writers and their varied learner needs. Thus, targeted instruction is essential to provide effective enhancement to nonnative English writers' lexical performance in academic writing.
