Description
This Qualitative Grounded Theory study is based upon interviews with charter school administrators, teachers and Hispanic parents to gather their perspectives on what practices encourage and elevate the participation of Hispanic parents in schools. There were three Guiding Questions utilized: 1) What culturally compatible methods are utilized in order to attract Hispanic parents to choose the particular charter school? 2) What culturally compatible methods does the charter school administration utilize to encourage Hispanic parental involvement in their child's education? 3) What are the benefits of greater Hispanic parent participation for children at these charter schools. Hypotheses were generated from the interviews base upon literature review. For Guiding Queston #1 there were five hypotheses based on a. Personal Interactions/Relationships, b. Environment, c. Language accommodations, d. Communication, e. Family Services. For Guiding Question #2, there were two hypotheses based on: a. Staff experience with Hispanic community and b. Leadership building. For Guiding Question #3, there were three hypotheses based on a. Home/School Partnerships, b. Academics, and c. Physical Presence.

Description
ABSTRACT Teachers working in isolation to overcome instructional challenges are left to their own devices, but teachers working together can benefit from others' perspectives. Teacher collaboration can increase communication and open doors to increased collective knowledge and rapport. Collaborative knowledge sharing and decision-making that focus on student achievement can go far in improving instructional learning. This action research focused on increasing collaboration among members of a middle school team of teachers. Involving teachers in a collaboration development processes was intended to improve productive interactions and contribute to instructional learning as a professional learning team. Study participants were involved in an eight week professional development initiative that involved techniques to promote collaboration along with instructional learning tools to promote professional learning in regard to guiding students to high levels of cognition. A mixed methods set of data was generated including a research journal, artifacts, surveys, meeting transcriptions, and interviews. Findings concluded that focusing on collaboration contributed to positive changes in the middle school team's interactions. Setting and revisiting norms of collaboration were crucial steps in this focus, leading to increased buy-in and active participation during team meetings. Focusing on relevance contributed to multiple aspects of the team's instructional learning. Participants valued their collaborative efforts especially when they found direct links between their professional learning and their individual classroom situations. Focusing on an action plan also contributed to participants' instructional learning. Setting manageable short terms goals gave the team direction and fostered accountability. Finally, working as a professional learning team contributed to the team's instructional learning. Taking the time to meet frequently allowed teachers to share classroom experiences, assist one another, and develop professionally.

Description
This research is a reversal of the traditional concept of the student-teaching research experiment. Instead of studying the clear and stated goal of an apprenticeship, that of a pupil learning from the tutelage of a master, the focus here is on what a mentor-teacher learns from a student-teacher. During the act of teaching a novice, what can a mentor-teacher learn about her own practice, while demonstrating it to a pre-service teacher? Using the conceptual framework of the National Board for Professional Teaching Standards' Architecture of Accomplished Teaching, and using it within a framework centered around cognitive coaching and reciprocal mentoring, this action research study implemented an intervention that called for series of five cognitive coaching cycles between a mentor- and student-teacher designed to foster dialogue and reflection between them. The ultimate aim of this case study was to help determine what a mentor-teacher learned about her own practice as a result of mentoring a student-teacher. Qualitative data were collected over sixteen weeks in a charter high school. Five findings were identified created after the data were analyzed using a grounded theory approach, and four conclusions were drawn about the intervention's role in the mentor-teacher's reciprocal learning.

Description
There is a nationwide gap in which African American, Hispanic and low-income students perform significantly lower than their peers. Research suggests that teachers hold lower expectations for these students resulting in lower achievement. There are four main factors that influence teacher expectations: stereotypes, teacher self-efficacy, school culture, language and formal policies and programs aimed at increasing teacher expectations. The purpose of this study was to inquire into the following questions: (1) What are the factors that influence teachers' academic expectations for low-income and minority students? (2) What are teacher's perceptions on the effectiveness of formal policies and programs that are aimed at increasing teacher expectations? More specifically, do teachers feel that top-down formal policies, such as teacher evaluations, uniform curriculum, and performance-based pay are effective in impacting their expectations, or do teachers believe that bottom-up policies, such as book studies and professional learning communities, make more of an impact on increasing their expectations? Ten teachers were interviewed in a school district that is consistent with the state and national achievement gap. The findings revealed that teacher expectations are influenced by the four factors I found in the research as well as two other factors: a cultural disconnect among teachers and students and teachers' level of motivation. A combination of top-down and bottom-up formal policies and programs are needed as teachers are individuals and all respond to various forms of formal policies and programs differently.

Description
Galaxies with strong Lyman-alpha (Lya) emission line (also called Lya galaxies or emitters) offer an unique probe of the epoch of reionization - one of the important phases when most of the neutral hydrogen in the universe was ionized. In addition, Lya galaxies at high redshifts are a powerful tool to study low-mass galaxy formation. Since current observations suggest that the reionization is complete by redshift z~ 6, it is therefore necessary to discover galaxies at z > 6, to use their luminosity function (LF) as a probe of reionization. I found five z = 7.7 candidate Lya galaxies with line fluxes > 7x10-18 erg/s/cm/2 , from three different deep near-infrared (IR) narrowband (NB) imaging surveys in a volume > 4x104Mpc3. From the spectroscopic followup of four candidate galaxies, and with the current spectroscopic sensitivity, the detection of only the brightest candidate galaxy can be ruled out at 5 sigma level. Moreover, these observations successfully demonstrate that the sensitivity necessary for both, the NB imaging as well as the spectroscopic followup of z~ 8 Lya galaxies can be reached with the current instrumentation. While future, more sensitive spectroscopic observations are necessary, the observed Lya LF at z = 7.7 is consistent with z = 6.6 LF, suggesting that the intergalactic medium (IGM) is relatively ionized even at z = 7.7, with neutral fraction xHI≤ 30%. On the theoretical front, while several models of Lya emitters have been developed, the physical nature of Lya emitters is not yet completely known. Moreover, multi-parameter models and their complexities necessitates a simpler model. I have developed a simple, single-parameter model to populate dark mater halos with Lya emitters. The central tenet of this model, different from many of the earlier models, is that the star-formation rate (SFR), and hence the Lya luminosity, is proportional to the mass accretion rate rather than the total halo mass. This simple model is successful in reproducing many observable including LFs, stellar masses, SFRs, and clustering of Lya emitters from z~ 3 to z~ 7. Finally, using this model, I find that the mass accretion, and hence the star-formation in > 30% of Lya emitters at z~ 3 occur through major mergers, and this fraction increases to ~ 50% at z~7.

Description
Higher education institutions in the state of Arizona have experienced a reduction in government funding due to the economic challenges the state is facing combined with an ongoing national recession. Three higher education institutions studied are located in Phoenix, Arizona. The three higher education institutions are Phoenix College, Arizona State University and The University of Phoenix. An analysis of documents made public by each institution was conducted and high level administrators at each institution were interviewed to learn about revenue streams currently active and planned. The results of this set of analyses were presented to the leadership team of Phoenix College in a three-hour strategic planning and priority setting meeting. The action research study assisted Phoenix College administrators in gaining knowledge about and initiating action plans to increase revenue through entrepreneurial strategies. Increased funding is necessary to offset reductions in state aid and property tax revenues. Implementing entrepreneurial strategies to increase funding can promote self-reliance and flexibility and can mitigate the damage to institutional mission success that is threatened by reductions in traditional funding. The strategic planning and priority setting exercise conducted at Phoenix College produced three immediate outcomes: it informed the community of practice about entrepreneurial strategies to increase funding that are in use by higher education institutions located in greater Phoenix, Arizona; it influenced the community of practice to examine entrepreneurial revenue streams and; it committed the leadership team to pursuing and enlarging three additional revenue streams.

Description
To sustain world preeminence, 21st century university and college leaders in the United States are redesigning their institutions organizationally and culturally to align with the direction of local and global societies and markets. The New American University enterprise model at Arizona State University has become one of the leading organization and cultural redesigns in United States higher education since its inception in 2002. Yet, sustaining a 21st century model such as this one means every individual in the college or university must understand his or her specific role to further progress the new model forward. Therefore, to advance and sustain a 21st century higher education redesign model at a U.S. college or university, it becomes imperative that every master-level professional who works in the academic/student services field at the institution understand his or her specific role in helping to further progress the new model forward. To this end, there is a need to change the way graduate students in higher education/student affairs masters programs are educated to work in the 21st century institution. This change can prepare new professionals to understand these enterprise models and how to integrate them into their practice in order to meet the needs of the institution, local and global societies and markets. The purpose of this action research study is to highlight one program, the ASU M.Ed. Higher and Postsecondary program, and show how graduates from 2007 - 2011 understand New American University concepts and integrate them into professional practice within higher education. Through use of a quantitative approach, this action research study described how the ASU M.Ed. in Higher and Postsecondary program graduate students' understanding of New American University concepts informs their thinking and practice to lead and respond to changes and challenges facing today's 21st century higher education field.

This dissertation reports on an action research study that sought to discover how a new WiFi, tablet computing device, the Apple iPad, affected, enhanced, and impacted student engagement in an English Honors course at Scottsdale Community College. The researcher was also the instructor in the two semester, first-year, college composition sequence (English 101/102) in which all 18 students were provided the new Apple iPad tablet computing device. The researcher described how students adapted the Apple iPads to their academic lives, assessed iPad compatibility with current instructional technology systems, and interviewed participating students to document their beliefs about whether iPad activities enhanced the course. At the conclusion of the college composition sequence, 13 students agreed to participate in focus groups to describe how they made use of the iPad and to report on how the iPad influenced their engagement. Among other findings, students reported that there were compatibility problems with current SCC instructional technology systems, that the iPad increased their efficiency in completing informal educational tasks, but that the iPad was not useful for doing word processing and research. Recommendations for future use of the iPad in this course include reducing the number of iPads accessing the WiFi network at the same time, piloting the use of iPad word processing applications, researching more "mobile-friendly" web sites and documents, and developing innovative assignments that take advantage of iPad capabilities.

Description
There are many lines of evidence for anisotropy at all scales in the explosions of core collapse supernovae, e.g. visual inspection of the images of resolved supernova remnants, polarization measurements, velocity profiles, "natal kicks" of neutron stars, or spectroscopic observations of different regions of remnants. Theoretical stability considerations and detailed numerical simulations have shown that Rayleigh-Taylor (RT) instabilities arise in the star after the explosion, which leads to the early fragmentation of parts of the ejecta. The clumps thus created are of interest to a variety of topics, one of them being the formation environment of the solar system. There is a high probability that the solar system formed in the vicinity of a massive star that, shortly after its formation, exploded as a core collapse supernova. As argued in this thesis as well as other works, a core collapse supernova generally is a good candidate for chemically enriching the forming solar system with material. As forming proto--planetary systems in general have a high probability of being contaminated with supernova material, a method was developed for detecting tracer elements indicative supernova contamination in proto--planetary systems.The degree of the anisotropy of the supernova explosion can have dramatic effects on the mode of delivery of that material to the solar system, or proto--planetary systems in general. Thus it is of particular interest to be able to predict the structure of the supernova ejecta. Numerical simulations of the explosions of core collapse supernovae were done in 3 dimensions in order to study the formation of structure. It is found that RT instabilities result in clumps in the He- and C+O rich regions in the exploding star that are overdense by 1-2 orders of magnitude. These clumps are potential candidates for enriching the solar system with material. In the course of the further evolution of the supernova remnant, these RT clumps are likely to evolve into ejecta knots of the type observed in the Cassiopeia A supernova remnant.

In 2005, the Navajo Sovereignty in Education Act was signed into law by the Navajo Nation. Like the No Child Left Behind Act, this Navajo Nation legislation was as much a policy statement as it was a law. It marked the first time that the Navajo Nation linked sovereignty with education by expressing its intent to control all education within its exterior boundaries. The objective of the law was to create a department of education that would resemble the states of Arizona, New Mexico, and Utah in which the Navajo Nation resides. Through their department of education, the Navajo Nation would operate the educational functions for its populace. This study looked at the implications and impact that perspectives of this law would have on public schools within Arizona from the perspective of five superintendents in Arizona public schools within the Navajo Nation were gained through open-ended interviews. It examined the legal, fiscal, and curricular issues through the prism of sovereignty. Through the process of interviews utilizing a set of guided questions in a semi-structured format, five superintendents in Arizona public schools within the Navajo Nation shared their perspectives. Analysis of the five interviews revealed curriculum, funding, jurisdictional, and fear or mistrust as problems the Navajo Nation will need to overcome if it is to begin full control of all aspects of education within its boundaries. There is a strong need for the Department of Dine' Education to educate public schools with regards to the Navajo Nation Sovereignty in Education Act of 2005. Administrators need more training in tribal governments. Like the constitution, the Navajo Sovereignty in Education Act will be interpreted differently by different people. But, without action, it will be ignored. Within the Act's pages are the hopes of the Navajo Nation and the dreams for our young Navajo students.
