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.

Learning phrasal verbs (PVs) is of vital importance in both written and spoken English, especially for those English learners who must use English as a second language (ESL) in their daily interactions with proficient speakers. This study focused on two particles (out and in) in exploring a more effective model for presenting PVs in an ESL context. PVs are the focus of this empirical study because they are an essential component of English vocabulary but are typically regarded as very difficult for ESL students to master. This study used a quasi-experimental design to compare the effect of instruction through image-schematic container illustrations of 16 PVs (supported by the container metaphor model) and a definition-only illustration of the same 16 PVs (supported by the traditional model of PV instruction). The participants in this experiment consisted of 28 intermediate-level students enrolled in intensive English program (IEP) courses at a metropolitan college in the southeastern United States during the summer of 2019; the students were divided into a control group and an experimental group. Four types of instruments, including one pretest and three posttests, were used in this experiment to examine the effectiveness of the container metaphor model compared with the traditional model. The findings of this study challenge the traditional view regarding the difficulty of teaching the meanings of these 16 PVs and suggest that the container metaphor model is more conducive to PV learning and retention. However, the findings of this study showed little evidence that the container metaphor model can assist in guessing the meaning of previously unknown PVs. The practical implications demonstrated from these results can be used by ESL teachers and educational stakeholders to validate English-teaching practices. Therefore, this model was recommended to be considered as one model of presenting PVs. The current study demonstrated that researchers should include infrequent PVs in their research in addition to the frequent ones. Finally, limitations of the current study are identified and recommendations for organizing future studies on this topic are proposed.

AbstractTeachers make decisions about which resources to use in their classrooms daily, including text selection for read-aloud. This impacts students in classrooms nationwide, as these decisions validate some voices and marginalize others. This study used the Q-methodology in a concurrent mixed-methods design to explore what beliefs influence decision-making as teachers in Grades 3-6 select texts to share for read-aloud and where these beliefs originated. Teacher participants identified priorities in text selection using a forced-rank Q-sort and reflected individually on their text selection process for read-aloud. Data were then analyzed using exploratory factor analysis (EFA) to delineate factor groups with similar priorities within the participant sample. These groups were interviewed to investigate commonalities more deeply and look for common origination spaces. Participants identified different priorities in text selection; texts that help students examine and stretch their own thinking were most common. The sample clustered into 4 dominant viewpoints about text selection for read-aloud: read-aloud as a curriculum tool, a relationship building tool, a pathway to explore diversity, or an invitation to school and reading. Teachers struggled to identify a single priority in their text selection process; top priorities in the Q-sort were identified, however, self-reflections revealed many other influences that affected final book choices. Teachers identified the origins of their beliefs about text selection and felt that the text selection process could change during a teacher’s career. Recommendations based on findings along with implications for policy and practice are shared in the discussion. Keywords: read-aloud, beliefs, decision making, q methodology, teachers

This study sought to investigate the self-perceived factors that led adult language learners, who acquired L2 after the critical period, to acquire native like pronunciation in their second language. Given the impact of accent and pronunciation on perceptions of a speaker's status, intelligence and/or competence, there exists a need for thoughtful and comprehensive research into why adult second language learners reach different outcomes in pronunciation attainment. A qualitative phenomenological design was employed to recruit adults who began learning English as an L2 after 12 years old but attained a native-like English accent. Participants recorded vocal samples that were presented with native speaker control-recordings to three native speaking judges. Two participants were judged to be native-like and then were invited to separate semi-structured interviews. These interviews collected data on the nature of the participants' language acquisition experience. Results revealed common experiences, supported by previous research, of a.) Interest in L2 beyond academics, b.) L2 and identity construction, and c.) cultivation of L2 social networks in target speaking countries. Results also revealed experiences that diverged from previous research relating to d.) use of metacognitive strategies and e.) attitudes toward pronunciation in the L2. These findings expand on the limited scholarship exploring the development of exceptional pronunciation in adults and provide a model of a targeted qualitative methodology for future research to continue investigating the unique experience of these exceptional learners.
