Doctor of Philosophy / Curriculum and Instruction Programs / Socorro G. Herrera / This quasi-experimental study was designed to measure the effects of a research-based intervention on fourth and fifth grade culturally and linguistically diverse students' vocabulary development. Through the extensive review of literature on vocabulary instruction and second language acquisition, a substantive theoretical framework titled the IBA Framework was developed. The IBA Framework incorporates characteristics of effective vocabulary instruction by accessing students' background knowledge, connecting unknown vocabulary words to known knowledge, ensuring opportunities for meaningful use of the vocabulary words, providing multiple exposures, and focusing on higher-level word knowledge. The IBA Framework also addresses second language acquisition by incorporating the linguistic, academic, cognitive, and sociocultural processes of the prism model. The IBA Intervention, derived from the IBA Framework, examined the affect of targeted vocabulary strategies on the overall vocabulary development of Culturally and Linguistically Diverse (CLD) students. Quantitative and qualitative methodologies were utilized for data collection and analysis. Quantitatively, the affect of the IBA Intervention was measured by the Measurement of Academic Progress (MAP) assessment and the Ecobehavioral System for the Contextual Recording of Interactional Bilingual Environments (ESCRIBE). MAP assessment scores were used to measure the overall literacy achievement of CLD students. Analysis of the data indicated that the treatment group made greater gains than the control group. ESCRIBE was used to measure students' overall engagement. The affect of the IBA Intervention was measured by combining the results of three student variables: language initiating/responding behaviors, oral responses, and activity-related responses. The overall engagement scores indicated that CLD students who received the IBA Intervention had higher levels of engagement than the control group. Qualitatively, the affect of the IBA Intervention on students' vocabulary retention was investigated using student documents, participant observation, and informal interviews. The emic perspective that emerged from the data suggested that students in the intervention group demonstrated their vocabulary retention by building vocabulary knowledge, clarifying vocabulary knowledge, extending vocabulary knowledge, and using vocabulary knowledge across settings. Exemplars from each of these categories were provided as evidence of the CLD students' attainment of a deeper level of permanent vocabulary knowledge.

abstract: One of the major issues confronting education in Arizona and across the United States has been the consistent low performance of culturally and linguistically diverse (CLD) students in comparison to their peers as evidenced by the disparity of the achievement gap at every level in the educational pipeline. A contributing factor has been the lack of teacher preparation focused on teaching CLD students. Preparation focused on a culturally responsive curriculum about dispositions and pedagogical knowledge and skills as well as field experience placement with CLD students have been previously identified areas to consider when training preservice teachers (PSTs). Therefore, this study examined how a Culturally Responsive and Linguistic Teaching (CRLT) Framework would raise preservice teacher’s critical consciousness about teaching CLD students. The CRLT Framework focused on two specific areas; (a) a culturally responsive curriculum and (b) a team-based service-learning experience. The CRP curriculum included lessons designed to increase PSTs understanding about how their sociolinguist views influenced their pedagogical knowledge about teaching CLD students. In addition, the team-based service-learning approach, as a community of practice, provided experiences for PSTs to apply theory to practice. A mixed method analysis was employed to collect and analyze the quantitative data (surveys) and qualitative data (interviews and photovoice). Results from this study suggested increases in PSTs’ knowledge, self-efficacy, and perceptions of usefulness of CRP in their future practices. The team-based, service-learning component, which was based on a community of practice framework, enhanced the learning experience by allowing students to move from theory to practice and served as an important contributing factor to the overall results. Given the findings of this research study, it appeared that an introductory course focused on a culturally responsive and linguistic teaching influenced PSTs’ dispositions, knowledge, and skills. Thus, providing an introductory course, earlier rather than later, has the potential to change the trajectory of preparing PSTs so they were more prepared to teach CLD students as they continued through their program of study. Results showed effective work with CLD students was about so much more than ‘just good teaching.’ / Dissertation/Thesis / Doctoral Dissertation Educational Leadership and Policy Studies 2019

Intern teachers are more likely to be placed in hard-to-fill content areas, such as math, science, and special education, which exacerbates their initial teaching experiences as teachers of record. For new teachers in their intern credential program, these factors compound the stress of attending coursework while managing their experience as a novice in the classroom. Without proper mentoring and support in these placements, teachers of color may perceive themselves as feeling less successful in the classroom. In this mixed methods study, the researcher investigated the types of support intern teachers of color need in successfully completing their teacher preparation program. Quantitative data were collected using archival research to determine perceived levels of preparedness by intern teachers of color. In alignment with explanatory sequential method, interviews were conducted to gather qualitative context to explain the quantitative data. Three themes emerged from the data analyses that formed these theories: (a) as a new teacher, it is common to feel overwhelmed, confused, or frustrated while trying to balance multiple demands; (b) teaching racially diverse students presents unique challenges; and (c) to thrive as a teacher, it is crucial to seek support from colleagues, mentors, and support networks. Implications for practice include systematizing strong mentorships, implementing teacher team models, and training intern support networks on cultural awareness. These findings provide information to intern programs about the types of support needed to be culturally responsive to the needs of both diverse teachers and the students they serve.

This collective case study explores the nature of the relationship between teachers’ use of culturally responsive teaching (CRT) practices and students’ engagement in constructing viable arguments and critiquing the reasoning of others (SMP3). This study was informed by the Common Core State Standards Initiative related to developing mathematically proficient students through the use of student engagement practices consistent with the standards for mathematical practice. As a means to support teachers’ facilitating specific student engagement practices, professional development was provided. This study is situated in the growing body of research associated with student engagement and cultural identity. The case of two teachers was defined from interviews, classroom observations, journal prompts, and student artifacts. Data was collected before, during, and after professional development following a cross-case analysis. Four themes emerged: (a) shift in teacher practice; (b) depth and breadth of the knowledge of culturally responsive teaching and standard for mathematical practice three; (c) teacher reflection and reception; and (d) classroom management. The findings suggest that the shift in teacher practice can be supported by professional development focused on reflective practice. This shift is impacted by classroom management and teachers’ depth and breadth of their knowledge of CRT and SMP3.

The purpose of this study was to investigate the role of academic libraries in providing services to culturally diverse student populations. In this study the information needs and information-seeking behaviour of the culturally diverse students of the Technikon Witwatersrand were analysed. The study also tried to establish whether there are differences in information needs and information-seeking behaviour of various cultural groups. The empirical investigation was conducted by means of focus group interviews and a questionnaire survey on a sample of undergraduate students of the Technikon Witwatersrand. There were assumptions that African students have limited experience in using the academic library, have no computer and information handling skills and might have language difficulties. Therefore, the expectation was that African students might have problems in the use of the academic library. However, the results of the empirical study show that English and Afrikaans speaking students are experiencing more problems than African students. / Information Science / M.Inf.

Achieving equitable opportunities to learn has been recognized as an important issue in multilingual content classrooms. However, partially because mathematics is conceptualized as a language-free subject, there is limited research examining linguistic minority students’ opportunities to learn in mathematics classrooms. The purpose of this research is to identify linguistic minority students’ opportunities to learn in mathematics classrooms in a Canadian multilingual urban elementary school, where English was the main instructional language. Drawing on cultural historical activity theory, this study focuses on two aspects of learning: externalization, which emphasizes learners’ creation of new cultural artifacts and new contexts to apply the given artifacts, and internalization, which emphasizes learners’ acquisition of preexisting cultural artifacts. In this ethnographic study, I examined the activity systems of participatory action research (PAR) with the activity system of regular mathematics lessons. Within these activity systems, I focused on newly-arrived English language learners’ (ELLs) participation. Specifically, I examined the range of opportunities to learn afforded to students in the two activity systems and identified how focal ELLs accessed these opportunities to learn. In the activity system of PAR, which emphasized externalization, students conducted research and presented their conclusions in order to implement changes in their school environment. All students, however, did not participate equally. Specifically, the focal ELLs were not able to access these opportunities to learn as a result of group dynamics, marginalized social identities, and other students’ perceptions of their linguistic ability. In the activity system of regular mathematics lessons, which emphasized internalization, the teacher organized lessons in ways that allowed focal ELLs to receive extra support and resources to reach the curriculum expectations. These mathematics lessons allowed focal ELLs to increase their participation through mathematical reasoning, problem solving, and explanations with a variety of resources including visual representations. A critical examination of the interactions revealed that focal ELLs’ opportunities to learn were expanded or limited depending upon classroom configurations. Furthermore, this research suggests that students’ social identities serve as both a medium and a product of learning. These results have valuable implications for developing inclusive classroom practices and curriculum in multilingual content classrooms.
