abstract: ABSTRACT This mixed methods study examines 126 community college students enrolled in developmental reading courses at a mid-sized Southwestern community college. These students participated in a survey-based study regarding their reading experiences and practices, social influence upon those practices, reading sponsorship, and reading self-efficacy. The survey featured 33 structured response prompts and six free response prompts, allowing for both quantitative and qualitative analysis. The study¡&brkbar;s results reflected the diverse reading interests and practices of developmental college students, revealing four main themes: -the diversity and complexity of their reading practices; -the diversity in reading genre preferences; -the strong influence of family members and teachers as reading sponsors in the past with that influence shifting to friends and college professors in the present; and, -the possible connection between self-efficacy and social engagement with reading. Findings from this study suggest these college students, often depicted as underprepared or developmental readers, are engaging in diverse and sophisticated reading practices and perceive reading as a means to achieve their success-oriented goals and to learn about the real world.This study adds to the limited field of community college literacy research, provides a more nuanced view of what it means to be an underprepared college reader, and points to ways community college educators can better support their students by acknowledging and building upon their socio-culturally influenced literacy practices. At the same time, educators can advantage students academically in terms of building their cultural capital with overt inculcation into disciplinary literacies and related repertoires of practice.

This dissertation consists of three related papers. The first paper, Rethinking mathematics bridge courses--An inquiry model for community colleges, introduces the activities of conventionalizing and axiomatizing from a practitioner perspective. In the paper, I offer a curricular model that includes both inquiry and traditional instruction for two-year college students interested in mathematics. In particular, I provide both examples and rationales of tasks from the research-based Teaching Abstract Algebra for Understanding (TAAFU) curriculum, which anchors the inquiry-oriented version of the mathematics bridge course. The second paper, the role of past experience in creating a shared representation system for a mathematical operation: A case of conventionalizing, adds to the existing literature on mathematizing (Freudenthal, 1973) by "zooming in" on the early stages of the classroom enactment of an inquiry-oriented curriculum for reinventing the concept of group (Larsen, 2013). In three case study episodes, I shed light onto "How might conventionalizing unfold in a mathematics classroom?" and offer an initial framework that relates students' establishment of conventions in light of their past mathematical experiences. The third paper, Collective axiomatizing as a classroom activity, is a detailed case study (Yin, 2009) that examines how students collectively engage in axiomatizing. In the paper, I offer a revision to De Villiers's (1986) model of descriptive axiomatizing. The results of this study emphasize the additions of pre-axiomatic activity and axiomatic creation to the model and elaborate the processes of axiomatic formulation and analysis within the classroom community.

The purpose of this study was to determine if any statistically significant difference exists between the self-efficacy scores of student teachers who began their college experience at the community college level and student teachers who began their education at the university level. The study was used to determine whether or not the type of initial college experience impacted the first two years of college study, in relation to the development of a sense of self-efficacy at the end of the program of study. Self-efficacy data were gathered from beginning student teachers at two comparative institutions. The participants were enrolled in the colleges of education at two large metropolitan universities. One university was located in southern Texas and the other was located in north central Texas. The Teachers' Sense of Efficacy Scale was the instrument used, as well as a researcher-made questionnaire that collected demographic data. In addition to pattern of education, other independent variables included age, gender, ethnicity, certification level sought by the participant, and the number of contact hours spent by the participant in early field experiences in K-12 classrooms. A multiple regression analysis indicated no statistically significant difference in the composite score of the Teachers' Sense of Efficacy Scale, a measure of self-efficacy. The TSES also loads on three factors: Instructional Strategies, Classroom Management, and Student Engagement. Multiple regression analyses of the individual factor scores indicated no statistically significant predictive ability for self-efficacy on any of the subscales across initial college experience. Multiple regression analyses as well as MANOVAs were conducted to determine if the demographic variables of gender, age, ethnicity, G.P.A, certification level, and contact hours impacted TSES scores. The dependent variable was the general self-efficacy scores and the individual factor scores (i.e., Student Engagement, Instructional Strategies and Classroom Management) of student teachers as measured by the TSES. Analyses indicated a positive relationship between age, pattern of education, and global self-efficacy scores. In addition, a statistically significant relationship was indicated between age, pattern of education, and the factor of Instructional Strategies. No statistically significant relationship was found between initial college experience and global TSES scores or factor scores across the other demographic variables.

This study explored what effect information literacy instruction (ILI) may have on both a generalized anxiety state and library anxiety specifically. The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college students and is characterized by feelings of negative emotions including, ruminations, tension, fear and mental disorganization (Jiao & Onwuegbuzie, 1999a). This often occurs when a student contemplates conducting research in a library and is due to any number of perceived inabilities about using the library. In order for students to become successful in their information seeking behavior this anxiety needs to be reduced. The study used two groups of international students enrolled in the English for Speakers of other Languages (ESOL) program taking credit courses. Each student completed Bostick's Library Anxiety Scale (LAS) and Spielberger's State-Trait Anxiety Inventory (STAI) to assess anxiety level before and after treatment. Subjects were given a research assignment that required them to use library resources. Treatment: Group 1 (experimental group) attended several library instruction classes (the instruction used Kuhltau's information search process model). Group 2 (control group) was in the library working on assignment but did not receive any formal library instruction. After the treatment the researcher and ESOL program instructor(s) measured the level of anxiety between groups. ANCOVA was used to analyze Hypotheses 1 and 2, which compared pretest and posttest for each group. Research assignment grades were used to analyze Hypothesis 3 comparing outcomes among the two groups. The results of the analysis ascertained that ILI was associated with reducing state and library anxiety among international students when given an assignment using library resources.

With an increasingly technological and competitive world economy, more jobs require employees to have achieved the advanced skills and knowledge gained only through postsecondary education. The data regarding the supply and demand between the workforce and higher education present a challenge for community college technical programs. These are the programs charged training the new workforce. An effort to increase the persistence and three-year graduation rate for technical students is one of Tarrant County College District's initiatives to prepare students for the workforce. Therefore, the purpose of this study was to determine factors that contribute to the three-year graduation rates of students enrolled in technical programs at the Northwest Campus of the Tarrant County College District. A quantitative survey approach was selected for this study targeting 191 technical students. The results of this study showed that females, who had established a degree plan and declared a major during the first two semesters at the urban community college campus under study, graduated in three years. The graduation rates for males in this study were lower than for females. Also, technical students who were 18 to 35 years old were more likely to graduate. Students who did not complete a degree plan in the first two semesters did not graduate in the three-year time frame. For the 77 respondents, students were more likely to graduate if they declared a major and established a degree plan. Implications for practice and recommendations for further study are provided.

The purpose of this study was to examine differences and relationships in student definition and background characteristics, help seeking behaviors, academic and environmental variables between and among community college students at a single institution who successfully completed and those who did not complete online courses during a single term. An adapted version of Bean and Metzner's conceptual model of nontraditional student attrition provided the theoretical framework for the study. The results of data analysis revealed statistically significant differences between completers and noncompleters on the basis of definition, gender, ethnicity, experience and prior GPA. Statistically significant relationships were found between definition, ethnicity, gender, experience, prior GPA, orientation and completion and noncompletion. No statistically significant interactions were found between definition and experience and help seeking behaviors. No statistically significant differences, relationships or predictor variables were found by degree seeking, preassessment, or technical help seeking. Additional analyses by defining characteristics revealed statistically significant differences between completers and noncompleters on the basis of residency, age and enrollment status. Predictor variables found to be significant were definition, gender, experience, prior GPA and orientation. The odds of completion increased with nontraditional definition, female gender, higher prior GPA, and orientation participation. The odds of completion decreased with experience.
