Description
This study contributes to the ongoing discussion of Mathematical Knowledge for Teaching (MKT). It investigates the case of Rico, a high school mathematics teacher who had become known to his colleagues and his students as a superbly effective mathematics teacher. His students not only developed excellent mathematical skills, they also developed deep understanding of the mathematics they learned. Moreover, Rico redesigned his curricula and instruction completely so that they provided a means of support for his students to learn mathematics the way he intended. The purpose of this study was to understand the sources of Rico's effectiveness. The data for this study was generated in three phases. Phase I included videos of Rico's lessons during one semester of an Algebra II course, post-lesson reflections, and Rico's self-constructed instructional materials. An analysis of Phase I data led to Phase II, which consisted of eight extensive stimulated-reflection interviews with Rico. Phase III consisted of a conceptual analysis of the prior phases with the aim of creating models of Rico's mathematical conceptions, his conceptions of his students' mathematical understandings, and his images of instruction and instructional design. Findings revealed that Rico had developed profound personal understandings, grounded in quantitative reasoning, of the mathematics that he taught, and profound pedagogical understandings that supported these very same ways of thinking in his students. Rico's redesign was driven by three factors: (1) the particular way in which Rico himself understood the mathematics he taught, (2) his reflective awareness of those ways of thinking, and (3) his ability to envision what students might learn from different instructional approaches. Rico always considered what someone might already need to understand in order to understand "this" in the way he was thinking of it, and how understanding "this" might help students understand related ideas or methods. Rico's continual reflection on the mathematics he knew so as to make it more coherent, and his continual orientation to imagining how these meanings might work for students' learning, made Rico's mathematics become a mathematics of students--impacting how he assessed his practice and engaging him in a continual process of developing MKT.

Description
The purpose of this study is to explore the literacy practices members of an online fan community engage in to participate in the space and to question what learning happens through that participation. This dissertation is the product of a two-year virtual ethnographic study of The Sims Writers' Hangout (SWH), a discussion forum website established by fans of The Sims to support members' interests in creating and sharing Sims fan fiction. Affinity space theory informs an understanding of SWH's organization, and a definition of literacies as situated, social practices also frames the study. Data were collected following a discourse-centered online ethnographic approach, which guided systematic observation and interactions with eight key informants. The data corpus includes hundreds of pages of discussion forum posts, member profiles, moderator-created norming texts, numerous digital, multimodal Sims fan fiction texts, virtual interview responses from informants, field notes, and additional virtual artifacts, such as informants' websites and Flickr® photostreams. Study results are presented within three separate manuscripts prepared for publication and presentation, each exploring different lines of inquiry related to SWH. Chapter 3 focuses on tensions visible in the forum discussions to argue for an expansion of affinity space theory that accounts for the “hanging out” members do in the space. Chapter 4 analyzes one informant's literacy practices using a Design perspective. This analysis reveals the collaborative nature of Sims fan fiction literacies. The final manuscript (Chapter 5) offers an analysis of SWH pedagogy using Bernstein's pedagogic device concept. Data illustrate how pedagogic discourse in this online, informal learning space aligns with and challenges Bernstein's theory. Finally, Chapter 6 offers conclusions about how these three analyses expand our understanding of adolescent literacies and 21st century learning. This chapter also contains implications for theory and practice, recommendations for future research, and reflections on lessons learned.

Description
The pace of technological development and the integral role technologies play in the lives of today's youth continue to transform perceptions and definitions of literacy. Just as the growth in completely online texts and the use of audio books and e-readers expands the definition of reading, digital platforms like blogs expand the notion of literary response and analysis. Responding to the complexities of literacy, this study examines the ways in which the literacy practice of blogging about young adult literature might elicit the active, intellectual orientation, or habits of mind, often sought in adolescent literacy development. Employing Gardner's Five Minds theory as an analysis tool and what Erickson calls "key linkages" as a framework, blog transcripts were read and coded. Those coded literacy acts were then linked to reveal any evidence of the creating, respectful, ethical, disciplined, and synthesizing habits of mind. From these overlays, empirical data tables emerged, accompanied by integrated case study narratives. Empirical data illustrate the aspects of the cases, and exposition provides a feature analysis of the habits of mind observed during blogging as a form of literary response to young adult literature. Results of this study suggest that bloggers writing about young adult books in a weblog environment reveal 1) some proficiency at synthesizing material, 2) a tendency to evaluate, 3) only moderate demonstration of the disciplined and respectful/ethical habits, 4) minimal evidence of the creating mind, and 5) moderate proficiency in basic transactional writing. Aligning with previous research, Talking with Our Fingertips illuminates possibilities for adopting pedagogical principles that provide student agency and potentially increase motivation and productivity.

Description
The purpose of this study was to analyze the impact of a context-based teaching approach (STS) versus a more traditional textbook approach on the attitudes and achievement of community college chemistry students. In studying attitudes toward chemistry within this study, I used a 30-item Likert scale in order to study the importance of chemistry in students' lives, the importance of chemistry, the difficulty of chemistry, interest in chemistry, and the usefulness of chemistry for their future career. Though the STS approach students had higher attitude post scores, there was no significant difference between the STS and textbook students' attitude post scores. It was noted that females had higher postattitude scores in the STS group, while males had higher postattitude scores in the textbook group. With regard to postachievement, I noted that males had higher scores in both groups. A correlation existed between postattitude and postachievement in the STS classroom. In summary, while an association between attitude and achievement was found in the STS classroom, teaching approach or sex was not found to influence attitudes, while sex was also not found to influence achievement. These results, overall, suggest that attitudes are not expected to change on the basis of either teaching approach or gender, and that techniques other than changing the teaching approach would need to be used in order to improve the attitudes of students. Qualitative analysis of an online discussion activity on Energy revealed that STS students were able to apply aspects of chemistry in decision making related to socioscientific issues. Additional analysis of interview and written responses provided insight regarding attitudes toward chemistry, with respect to topics of applicability of chemistry to life, difficulties with chemistry, teaching approach for chemistry, and the intent for enrolling in additional chemistry courses. In addition, the surveys of female students brought out subcategories with regard to emotional and professional characteristics of a good teacher, under the category of characteristics of teaching approach. With respect to the category of course experience, subcategories of useful knowledge to solve real-life problems and knowledge for future career were revealed. The differences between the control group females and STS group females with respect to these characteristics was striking and threw insight into how teacher behavior and teaching approach shape student attitudes to chemistry in case of female students.

Description
In this mixed-methods study, I examined the relationship between professional development based on the Common Core State Standards for Mathematics and teacher knowledge, classroom practice, and student learning. Participants were randomly assigned to experimental and control groups. The 50-hour professional development treatment was administered to the treatment group during one semester, and then a follow-up replication treatment was administered to the control group during the subsequent semester. Results revealed significant differences in teacher knowledge as a result of the treatment using two instruments. The Learning Mathematics for Teaching scales were used to detect changes in mathematical knowledge for teaching, and an online sorting task was used to detect changes in teachers' knowledge of their standards. Results also indicated differences in classroom practice between pairs of matched teachers selected to participate in classroom observations and interviews. No statistical difference was detected between the groups' student assessment scores using the district's benchmark assessment system. This efficacy study contributes to the literature in two ways. First, it provides an evidence base for a professional development model designed to promote effective implementation of the Common Core State Standards for Mathematics. Second, it addresses ways to impact and measure teachers' knowledge of curriculum in addition to their mathematical content knowledge. The treatment was designed to focus on knowledge of curriculum, but it also successfully impacted teachers' specialized content knowledge, knowledge of content and students, and knowledge of content and teaching.

Description
The research indicated effective mathematics teaching to be more complex than assuming the best predictor of student achievement in mathematics is the mathematical content knowledge of a teacher. This dissertation took a novel approach to addressing the idea of what it means to examine how a teacher's knowledge of mathematics impacts student achievement in elementary schools. Using a multiple case study design, the researcher investigated teacher knowledge as a function of the Mathematics Teaching Cycle (NCTM, 2007). Three cases (of two teachers each) were selected using a compilation of Learning Mathematics for Teaching (LMT) measures (LMT, 2006) and Developing Mathematical Ideas (DMI) measures (Higgins, Bell, Wilson, McCoach, & Oh, 2007; Bell, Wilson, Higgins, & McCoach, 2010) and student scores on the Arizona Assessment Collaborative (AzAC). The cases included teachers with: a) high knowledge & low student achievement v low knowledge & high student achievement, b) high knowledge & average achievement v low knowledge & average achievement, c) average knowledge & high achievement v average knowledge & low achievement, d) two teachers with average achievement & very high student achievement. In the end, my data suggested that MKT was only partially utilized across the contrasting teacher cases during the planning process, the delivery of mathematics instruction, and subsequent reflection. Mathematical Knowledge for Teaching was utilized differently by teachers with high student gains than those with low student gains. Because of this insight, I also found that MKT was not uniformly predictive of student gains across my cases, nor was it predictive of the quality of instruction provided to students in these classrooms.

Description
Drawing on Lave and Wenger (1991) this study explores how preservice elementary teachers develop themselves as teachers of mathematics, in particular, from the time of their teacher education courses to their field experiences. This study also researches the critical experiences that contributed to the construction of their identities and their roles as student teachers in their identity development. The stories of Jackie, Meg, and Kerry show that they brought different incoming identities to the teacher education program based on their K-12 school experiences. The stories provide the evidence that student teachers' prior experience as learners of mathematics influenced their identities as teachers, especially their confidence levels in teaching mathematics. During the mathematics methods class, student teachers were provided a conceptual understanding of math content and new ways to think about math instruction. Based on student teachers' own experiences, they reconstructed their knowledge and beliefs about what it means to teach mathematics and set their goals to become the mathematics teachers they wanted to be. As they moved through the program through their student teaching periods, their identity development varied depending on the community of practice in which they participated. My study reveals that mentor relationships were critical experiences in shaping their identities as mathematics teachers and in building their initial mathematics teaching practices. Findings suggest that successful mentoring is necessary, and this generally requires sharing common goals, receiving feedback, and having opportunities to practice knowledge, skills, and identities on the part of beginning teachers. Findings from this study highlight that identities are not developed by the individual alone but by engagement with a given community of practice. This study adds to the field of teacher education research by focusing on prospective teachers' identity constructions in relation to the communities of practice, and also by emphasizing the role of mentor in preservice teachers' identity development.

Description
The purpose of this mixed-methods action research study was to understand how a knowledge-building intervention changes the perception of rural high school juniors on the perception of staying local for college after high school. This study also investigates the ways in which participants used their social capital to begin to change the stigma of staying local for college. The intervention in this study was conducted at a public high school over 5 weeks with 21 high school juniors. College choice models, Social Influence Theory, and social capital theory framed the intervention. After the intervention, the scores for participants’ knowledge of the local university doubled on average, and every participant reported an increase in perception of the local rural university as a college choice for themselves or their peers. Participants reported a willingness to recommend the university to their peers. For students to make informed decisions about college choice, they must have adequate and accurate information. Research-based, targeted sessions delivered by dynamic college representatives or student ambassadors may increase knowledge and perception.

Description
This study was an action research study that explored teacher’s beliefs about student engagement and their role in student engagement through the development of a professional development innovation, the Transforming Student Engagement Professional Development program. This professional development program innovation was designed to lead participants through the stages of transformative learning theory and used the community of inquiry framework as the lens through which to explore student engagement strategies. A mixed-methods action research design was used to explore how participants transformed their feelings, beliefs, and assumptions around their online student engagement practices as they designed their online classroom as a community of inquiry. Pre/post Teacher Self Efficacy and Community of Inquiry surveys were used as well as a Learning Activities Survey and Interview. Study documents included calendars of training and agendas, participant journals, and my research memos.
Participation in the Transforming Student Engagement Professional Development program resulted in significant changes in the participants’ beliefs about student engagement, what their role in student engagement is, and their understanding and use of the Community of Inquiry framework as a lens through which to implement student engagement strategies.

Description
Student teachers in their final year of college preparation enter a profession that is facing a severe shortage and an alarming rate of attrition. Novice teachers, those with five or fewer years of experience, are faced with myriad challenges that makes retention a problem for the colleges preparing them, the school districts that hire them, and the students that need them in their classrooms.
This mixed methods action research study investigated an innovation designed to build student teacher self-efficacy. The expectation was it would increase the likelihood that new graduates would stay in the profession. The innovation taught student teachers to conduct action research within communities of practice. The Concerns-Based Adoption Model was used to monitor their progress.
It involved two phases. The first phase measured student teacher self-efficacy prior to and following the innovation, and the second phase measured self-efficacy of former graduates, novice teachers, who had graduated from the preparation same program. Both populations were interviewed to elaborate on the self-efficacy data.
Results suggested that student teachers who conducted action research within communities of practice showed a significant increase in self-efficacy. Specifically, the structure of action research guiding their collaborative efforts at problem-solving played a substantial role in increasing their confidence to face their future classroom challenges. The study also found that novice teachers who had performed the same action research within communities of practice retained a higher level of self-efficacy in their first five years of practice.
