This dissertation includes background on influences of mathematics, mathematics education, and who is viewed as a mathematician leading into three articles exploring students' and teachers' perceptions of mathematics through their lived experiences in both mathematics classrooms and their communities. Using interpretative phenomenological analysis for the methodology, all three articles analyze mathematics autobiographies and semi-structured interviews with five student participants enrolled in the same Algebra I course; Paper 3 also includes the Algebra I teacher. Paper 1 focuses on how students describe their lived experiences in mathematics classrooms. Three themes emerged from the participant data: 1) lack of autonomy and access, 2) feelings hinge on performance in mathematics, and 3) the need for support in mathematics. Each participant shared different experiences, but these experiences can help inform educators how to improve students' experiences in the classroom. Paper 2 sought to understand how middle grade students make sense of what it means to do mathematics in their community. The three themes include: 1) navigating the usefulness of mathematics outside of school, 2) who directs mathematics outside of school, and 3) the need for mathematics in future plans. Connections students made between mathematics and the lives outside of school varied suggesting how broad …

Today linguistic hybridity is often conceptualized as translanguaging. The present study of translanguaging was a linguistic ethnography, which meant investigating cultural issues as well as linguistic practices. The focus was on bilingual speakers of Vietnamese and English, two "named" languages that differ considerably in morphology, syntax, and orthography. This study, conducted over four and a half months, was situated in the Vietnamese Student Organization of a U.S. university, and it included 37 participants. The research was intended to answer two questions: what forms of translanguaging did these bilinguals use? and what reasons did they provide for instances of translanguaging? In capturing the language use of this community, my role was participant-observer, which entailed observing and audio-recording conversations in three kinds of settings: group meetings, social gatherings, and Facebook communications. Additional insights came from discourse-based interviews, focused on instances of translanguaging by 10 individuals. In the group meetings and Facebook conversations, it was conventional for the major language to be English, whereas in the social gatherings it was Vietnamese. My attention in analyzing these interactions was on patterns of translanguaging that occurred within sentences and those occurring outside sentence boundaries. Overall, most translanguaging occurred intra-sententially, as single words from one language …

This study was aimed at understanding the use of technology in early childhood school and home settings as well as its impact on students' social and language development, specifically with children aged four to seven from two schools (Kindergarten and elementary) in Kuwait. The study followed a qualitative design in which the interpretative approach was applied. Non-participant observations were conducted to gather data concerning the actual use of technology in the classrooms, they were followed by interviews with teachers and a group of parents from each classroom. The study used Vygotsky's social development theory as a framework for the analysis of data. The analysis showed limitations in the use of technology in the classroom; teachers identified a need for training to increase their knowledge about how to integrate technology into instruction. Also, the limited availability of up-to-date technology was viewed as a challenge. Teachers and parents agreed that the use of technology may foster social and language development for most students, on the condition that their use is supervised and guided by an adult. However, they also perceived that technology could have a negative impact on the development of students' social development, an area that requires further investigation.

The purpose of this study was to explore the practices of formal and informal teacher technologists in two school settings: an elite private, high school academy and an urban poor, middle school academy. This investigation included clarifying the role of the formal and informal teacher technologist and investigating the need for both formal and informal teacher technologists. This study also explored the technological differences between the public academy middle school and the private academy high school. Two formal and eight informal teacher technologists were interviewed face-to-face three times, each using the transcendental phenomenology research design. Each teacher technologist was also observed at least once in classroom and teacher training sessions. The results of this study revealed (1) the role of the teacher technologist was a fast technology problem solver; and (2) although students and teachers used technology, the schools lagged in adequate technology and/or teacher training; (3) the teacher technologists used the Internet to build and evaluate curriculum; (4) most students used tool software centered around project-based activities; (5) teacher technologists trained other teachers to be collaborative risk-takers in using technology; (6) teacher technologists shared what they learn with students and other teachers; and (7) students could be student-learners or …

This study explored how various intrapersonal, familial, and life-goal characteristics related to the academic and personal success of first semester early college entrants attending the Texas Academy of Mathematics and Science (TAMS) at the University of North Texas. The study sought to identify which intrapersonal factors and external factors affected grades, behavioral markers, and life satisfaction during the students' first semester at TAMS. Baseline data from TAMS entrance material such as standardized achievement test scores, previous grade point averages (GPA's), advanced courses taken, and other academic activities and awards were collected. Data were also collected from the students prior to their entry to the start of TAMS related to family cohesiveness, motivation, and career goals. Data from parents were gathered prior to the start of TAMS regarding parenting styles, demographics, parents' educational levels, careers, and income levels, as well as the child's homework, extracurricular activities, and other time demands. First semester grades, a measure of life satisfaction since the program began, and behavior reports from staff members were used as outcome/success indicators. These additional data were used to examine the relationship between success and familial/interpersonal/life goal factors.

The multiple case study investigated levels and types of transfer observed in a K-8 STEM (science, technology, engineering, math) academy in a project-based learning (PBL) environment. The academy was constructed two years prior to the study and conducive to PBL instruction. The students and teachers were in the second year of using PBL in the subject of science at the time of the study. The grade levels observed were second, fourth, and sixth grade and each grade level had three PBL units examined from the beginning to the end of the unit. The nine case studies, from the three different grade levels, were observed to identify Haskell's levels and types of transfer as determined by project requirements, observation of students, completed projects, and student interviews. The findings from this study showed that while projects moved the students beyond knowledge acquisition to application of knowledge in completed projects such as books, films, dances, etc., higher levels of transfer and more types of transfer were not evident. Therefore, based on the results of this study, the evidence of lower levels of transfer suggests that the PBL units, though inventive and potentially valuable to student learning, were not designed for higher levels of …
