Student attrition prior to the completion of a credential is an issue that has increasingly demanded the attention of stakeholders in higher education, particularly in the community college sector, in which less than half of all students complete a credential after six years. The costs of student attrition are high and widespread, ranging from the financial costs for institutions and federal and state governments to the personal and monetary costs paid by those students whose personal and professional goals are not achieved. With the ever-increasing focus on accountability for institutions of higher education and the growing movement toward performance-based funding, institutions are seeking to find ways to support all students on the path to completion of a credential. Building upon Braxton’s theory of powerful institutional levers that serve to promote student completion, Rendon's validation theory, and Schossberg's theory of marginality versus mattering, this two-part companion dissertation seeks to progress conversation beyond levers of retention as programmatic approaches to increasing student success. Through interviews with community college students serving as peer mentors in a student ambassador program and community college faculty identified by peers and supervisors as high performing in the area of student retention, the researchers seek to identify common characteristics, behaviors, backgrounds, conditions, and values possessed by effective human levers of retention. In doing so, the researchers hope to identify common characteristics among successful human levers of retention in the form of peer mentors and faculty members. This dissertation was created in collaboration with Kyle Barron, whose dissertation “It’s Not the Programs; It’s the People: Building Human Levers of Retention in Community Colleges” serves as a companion to this dissertation.

The purpose of this study was to explore the attitudes, beliefs, and practices of community college professors regarding education for sustainable development (ESD). In-depth interviews with 14 professors from different disciplines were conducted. The participants taught at Miami Dade College, Florida, a Talloires Declaration signatory since 2006, and all had attended Green Studies professional development workshops. Written documents such as assignments and samples of student work were used for triangulation. The annual report of the college’s Earth Ethics Institute and its Web site served as additional sources. The interviews were recorded, transcribed, and analyzed for common themes. The Talloires Declaration’s 10-point action plan and the key characteristics of ESD (UN DESD, 2006) served as the conceptual framework. The study found that the professors considered ESD an essential issue. The majority discussed the economic and social aspects of ESD; however, the environmental aspect was mentioned most frequently. The professors’ conceptualizations of ESD were influenced by their experiences and evidenced by the metaphors they used. Although their engagement with ESD differed, the professors expressed optimism toward ESD related teaching and learning. They regarded ESD as compatible with their subjects, and most had already been infusing sustainability into their courses or planned to do so. Additionally, the participants’ teaching practices reflected many of the characteristics of ESD. Even though the professors considered ESD challenging, they believed that they could make contributions to the college’s effort. The metaphor of “Planting a Seed” was frequently used to describe this holistic approach. The study also found that many professors regarded interpersonal relationships and communication significant factors for the advancement of ESD. The participants described several challenges to integrating ESD at their college. These related to time constraints, density of curriculum, institutional size and fragmentation, dearth of administrative support and incentives, students’ lack of academic preparation and sustainability awareness, students’ inability to focus on ESD because of personal, social, or economic circumstances, and professors’ frustration about a divisive atmosphere as a result of their engagement with sustainability. Despite these obstacles, the professors believed that ESD could be successfully woven into the community college experience.

Online learning has grown exponentially within higher education in the past decade, especially at community colleges. As online course offerings expand community colleges need to assess student learning in order to ensure quality learning experiences for students and for accreditation purposes. The purpose of this study was to compare the assessment methods of community college faculty who teach the same course in both face-to-face and online formats, in order to determine the similarities and differences that exist in assessment practices. This study stemmed from the constructionist and pragmatic perspectives of the researcher. Additionally this study asked how community college faculty perceive the effectiveness of different assessment methods on student learning. The method for this research was a qualitative multiple case study in which community college accounting faculty were interviewed to explore how they assess student learning in both the online and face-to-face formats. Homework problems, exams, quizzes were the most commonly used methods of assessment of student learning in both formats by the study participants. Furthermore, exams and quizzes were believed to be most effective in assessing student learning, among the community college faculty members interviewed. Another discovery from this study included the prevalent use of publisher's software,called My Accounting Lab, among community college accounting faculty in administering assessments to students. Additional concerns around assessing online students effectively, managing online student group work, and mitigating online student cheating were also revealed during interviews with study participants. / Graduation date: 2013

Faculty have been identified as critical players in the implementation of textbook affordability efforts at community colleges. Furthermore, emerging lower-cost alternatives to traditional textbooks present a wide and growing range of options that may help further efforts. This study sought to examine more closely the role of faculty with respect to textbook cost-lowering initiatives. The researcher utilized in-depth interviews to gain a rich picture of the experiences, attitudes, beliefs, and behaviors of nine full-time community college faculty as they confronted textbook affordability efforts and textbook alternatives. The interview data were analyzed using a thematic analysis process. Five major themes and three minor themes were identified. The five major themes were: (a) campus administrators support, but do not mandate, efforts; (b) frequent edition revisions frustrate faculty; (c) departmental approaches to textbook selection vary; (d) content, then affordability, drive selection choices; and (e) faculty have mixed feelings about textbook alternatives. The three minor themes were: (a) faculty efforts to save students money are thwarted by campus bookstores and financial aid policies; (b) English faculty benefit from public domain readings; and (c) more faculty participating in textbook selection means more difficulty deciding on a text. Implications and recommendations were offered for community college leaders, campus bookstores, publishers, and future researchers.
