The purpose of my dissertation study is to better understand the educational experiences of undergraduate engineering students within non-curricular learning environments, specifically in the form of extracurricular engineering groups or programs. I first conducted a content analysis of engineering education literature to identify where engineering design learning occurs, and to synthesize the implications of studies regarding engineering design learning. Aiming to fill a gap in the literature regarding non-curricular learning contexts, this study investigated what extracurricular groups and programs can educationally provide undergraduate engineering students by observing and interviewing students engaging in these environments. This study also aimed to identify if and how engineering students find navigational flexibility within engineering curricula, and how non-curricular learning environments might provide navigational flexibility. With regard to where engineering design learning occurs, the literature points to various educational contexts that effectively deliver engineering design education. Strategies that involve authentic and longer-term engineering design experiences tend to be the most impactful in terms of student outcomes and perceptions, however those experiences are not always implementable at larger scale. More traditional educational approaches to engineering design learning, though less impactful, are still effective delivery methods for introducing key aspects of engineering design education (e.g. modeling, global/societal/economic/environmental factors, communication skills). However, there was limited literature regarding more non-curricular learning experiences, such as learning in designed settings, outreach learning, learning media, and everyday informal learning. This literature review is one of the first attempts towards synthesizing where and how engineering design learning occurs, and has identified a significant gap in the literature regarding non-curricular educational settings. Addressing the identified gap in engineering education literature regarding non-curricular learning experiences, this dissertation study investigated five non-curricular engineering learning sites for undergraduate engineering students at a large research-driven state institution. Informed by the preliminary findings of a pilot study, I first investigated the salient features of engineering-related non-curricular activities from the students' perspectives using a self-directed learner autonomy framework to guide the study. Students participating in extracurricular engineering environments exhibited strong attributes of self-directed learners, particularly a willingness and ability to be challenged and to learn. The educational environments of the extracurricular opportunities cultivated these self-directed learning attributes by providing students a space to be exposed to an engineering community, authentic engineering work, and accessible resources. Findings from this portion of the dissertation indicated necessary modifications to the self-directed learner autonomy framework used to guide this study. The modified framework contributes a possible approach towards future assessment or research pursuits regarding non-curricular learning experiences in engineering. I also investigated the role non-curricular activities play in providing engineering students navigational flexibility through engineering curricula. Extracurricular engineering environments afford navigational flexibility by offering students opportunities to work on motivating challenges with and among supportive communities. By providing a space for students to express their engineering selves in primarily self-directed ways, extracurricular engineering experiences cultivate students' drive to find and pursue personally meaningful curricular and non-curricular educational experiences. However, institutional barriers, particularly time constraints and institutionally recognized achievements, stifle students' flexibility and willingness to pursue personally meaningful experiences. The findings of this study have helped uncover the various affordances non-curricular learning experiences provide engineering students, but more importantly, have identified the institutional barriers that prevent students from taking full advantage of non-curricular learning experiences. Based on these findings, I recommend that university and program level structures be reevaluated to encourage and provide students with more flexibility to find personalized learning experiences in and out of the classroom. / Ph.

The Technological Immersion Learning Theory (TILT) was developed through a classic grounded theory study in the seminal tradition of Glaser and Strauss (1967) and Glaser (1978, 1992, 1998, 2001, 2007). The purpose of the study was to investigate an exemplary case of self-determined technology enthusiasts in the hopes of generating a substantive grounded theory that conceptualizes their experiences and concerns. Twelve unstructured interviews of amateur radio enthusiasts from the eastern United States provided the initial / primary data for this study. Experimenting and self-teaching in technological activities was highlighted as the main concern of the participants. The basic social process (BSP) of technological immersion learning (TIL) emerged as a theoretical construct and core variable that illuminates the experiences of individuals immersed in a community of practice, where hands-on engagement with technology is a primary activity. Adventuring, Affirmation, Doing Technology, Experimenting, Overcoming Challenge, Self-teaching, and Social Networking were properties of technological immersion learning that interact dialectically in an amplifying causal loop, with Problem solving and Designing as active sub processes in response to unmet challenges. TIL occurs cyclically in three stages, beginning with Induction, a credentialing stage wherein the neophyte is prepared with the necessary knowledge and skill to become a novice participant in an activity. The transition from Induction into the Immersion phase is a status passage whereby the novice is absorbed into the technical culture of the group and commences autonomous active participation in hands-on experimenting. Hands-on experiences with experimenting, problem solving and social interactions provide diverse learning and affirmation for the doer and multiple sources of feedback that promote sustained engagement. The transition into the Maturation phase proceeds gradually over time, with prolonged engagement and cumulative gains in knowledge, skill, and experience. Maturation is a quasi-stable state that remains responsive to new contexts as a random-walk process, wherein trigger events can initiate new cycles of technological immersion learning in a perpetually evolving process of personal development. Engagement, Empowerment, and Self-Actualization are underlying dimensions of the TIL basic social process that provide the impetus for continued persistence and personal development. / Ph. D.

From 1959 -1964, the Prince Edward County, VA School Board closed down its public schools to circumvent the 1954 Brown v. Board of Education Supreme Court ruling declaring separate public schools for Black and White students "inherently unequal" and the 1955 Brown II ruling to desegregate public schools with "all deliberate speed." For five years, more than 1700 African American children received no public education in the county, as White children attended a newly-constructed and private Prince Edward Academy. While some students left Prince Edward to reside with relatives, others were placed with families by the American Friends Service Committee. However, the majority of Black children remained in the county without formalized public instruction. This study investigated the perceived impact of The Closing on adult self-directed learning, lifelong learning, occupational choices and success within a family with sixteen of its twenty-one children forced from school. Via audio-/video-taped interviews, three participants reflected upon their "lived experiences" during and since The Closing. Transcribed data were coded and analyzed based upon the major and underlying research questions guiding the study. Nine major conclusions were drawn from its findings: (a) The Closing perceivably impacted immediate educational goals of participants differently, (b) The Closing perceivably impacted specific and general long-range educational goals, (c) Participants have pursued educational goals via supportive spouses/family members and adult self-directed/lifelong learning measures, (d) Following the re-opening of schools, all respondents graduated high school, and two later enrolled in academic learning centers, (e) Self-directed learning has played an essential role in the lives of all participants, (f) All participants considered themselves life-long learners, (g) The Closing perceivably impacted the career plans of one participant, (h) Respondents acquired manufacturing and/or labor positions and were successfully employed throughout their adult lives, (i) Literacy assistance from family members, self-directed learning, on-the-job training and formalized coursework were perceived as having had a positive bearing on occupational success. The implications of this study suggested resiliency, family dynamics, family values, and narratological significance. Study participants, driven to live productive and successful lives, appeared to have emulated Adult Learning Theory tenets of self-directed, lifelong quests for formally-delivered and informally-acquired knowledge. Recommendations emerging from this study included investigations of School Closing survivors' motivations for adult learning, the role of faith in Closing survivors' lives, The Closing's perceived impact on the Next Generation, ancestral discourse, male birth order relationships, 1951 strikers' guilt, education vs. vocation and growth under adversity. / Ph.

No / Smart mobile devices, which are hand-held electronic devices with an advanced operating system (such as the Android platform) connected via a wireless protocol, have become an integral and essential part of our everyday life, and support both social and workplace activities. However, adopting mobile technology within the workplace setting can give rise to challenges that impact user behaviour and performance. A study was carried out amongst 90 participants located in two countries, using internet connectivity as a case study. Confidence and frustration have previously been connected with technology competence, but this was not applied to a workplace scenario during problem-solving, when users are assigned an unfamiliar smart mobile device. This research focuses on identifying the link between workplace users' levels of confidence and frustration when seeking to independently solve problems whilst completing familiar tasks on new smart mobile devices. A detailed video analysis of users' attitudes and behaviour during problem-solving was conducted, emphasising a correlation between attitudes and behaviour towards completing a task.

Doctor of Philosophy / Department of Counseling and Educational Psychology / Kenneth F. Hughey / This study examined the impact of two career interventions on the dysfunctional career thoughts (DCTs) and vocational identity (VI) of 55 high school seniors. Research has shown an inverse relationship between levels of DCTs and VI. One intervention was based on the Cognitive Information Processing approach (Peterson, Sampson, & Reardon, 1991; Peterson, Sampson, Lenz, & Reardon, 2002; Peterson, Sampson, Reardon, & Lenz, 1996; Sampson, Reardon, Peterson, & Lenz, 2004) and incorporated Improving Your Career Thoughts: A Workbook for the Career Thoughts Inventory (CTI workbook; Sampson, Peterson, Lenz, Reardon, & Saunders, 1996c) and the Self-Directed Search (SDS; Holland, 1994). The second intervention employed only the SDS. A control group used neither activity. Levels of DCTs and VI were assessed pre-intervention and post-intervention using the Career Thoughts Inventory (Sampson, Peterson, Lenz, Reardon, & Saunders, 1996a) and the Vocational Identity scale of My Vocational Situation (Holland, Daiger, & Power, 1980a). Earlier studies indicated improvements in levels of dysfunctional career thinking after CIP-based interventions (e.g., Kilk, 1998; Morano, 2005; Reed, 2006), but no previous studies employed the complete CTI workbook. Additional studies (e.g., Loughead & Black, 1990; Mau,1999; Wiggins, 1987) indicated that levels of vocational identity could be increased by using the SDS as an intervention. The combined use of the CTI workbook and SDS produced significant improvements in all five measures of DCTs and VI. It was also shown that use of the SDS as a stand-alone intervention did improve levels of VI, but not to the extent of the improvements shown by combined use of the SDS and CTI workbook. Use of the SDS as a stand-alone intervention did not produce improvements in levels of DCTs. The control group, which employed neither the CTI workbook nor the SDS, unexpectedly showed significant improvements in scores for two CTI scales which may have been due to the influence of confounding variables.

Guided by the conceptual framework of self-directed learning and culture, this study investigated the effectiveness of Title IV private, for-profit colleges and universities (FPCUs). Little research has examined this topic, which is problematic considering the disproportionate rate of student loan defaults experienced by Black FPCU borrowers. A phenomenological design was used to explore the meaning of academic achievement for Black doctorate recipients who attained a doctorate in psychology through an FPCU. This study specifically examined how Black students experience the completion of doctoral psychology programs at 2 FPCUs and what factors contributed to these students finishing their degrees. A unique-criterion-purposive sample of 7 Black students who completed doctoral psychology programs at FPCUs within the past 5 years was recruited to participate in telephone interviews. Moustakas' data analysis steps were applied to the data. The results indicated that study participants saw an association between attaining their doctorates in psychology and their self-actualization. They shared the experiences of selecting a suitable FPCU, choosing a specialty area, negotiating transfer credits, completing the doctoral coursework phase, and completing the dissertation phase. Their commitment to achieving self-actualization was a salient experience in finishing their degrees. A core aspect of self-actualization was their cultural knowledge, which helped them to overcome challenges and persevere. However, the results uncovered some insufficiencies in the FPCUs' practices. They have implications for positive social change by highlighting how FPCU academic support services might use cultural knowledge and self-actualization strategies to maximize the successful matriculation of Black students.

This study explores the web-navigation practices of adult learners in higher education and re-conceptualizes the concept of the organizing circumstance of self-managed learning, originated by Spear and Mocker (1984). The theoretical framework draws on funds of knowledge theory from a cultural historical perspective and elaborates a Vygotskian concepts of learning and development by introducing the notion of the distal object and the zone of distal development. The study employed a mixed methods design with an embedded multiple-case study involving half of the twelve participants using a new technology for self-managed learning called Zonebee. Zonebee recorded participants' web navigation, known as Zonebee Trails, providing quantitative data for analysis. Surveys were administered, namely the Metacognitive Awareness Inventory (Schraw&Dennison, 1994), the Index of Learning Styles Inventory (Soloman&Felder, 1986), a survey of technology use (created for this study) and a set of demographic questions. Eleven of the twelve participants also provided interviews in which they described their self-managed learning practices.Findings contradicted the premise in the literature that the learning environment fortuitously determines the learning experience. Participants primarily relied on the internet and computer to manage their learning and made deliberate choices about which tools to use depending upon the purpose of the constituent process of self-managed learning in which they were engaged (assessing, planning, implementing, monitoring, evaluating or producing). Zonebee Trails evidenced participants' engagement in considerable planning before generating focused queries to locate specific materials. Thus, this study suggests that the organizing circumstance operates, not through happenstance alone, but through the confluence of four factors influencing the direction the learner takes: funds of knowledge for learning; learning demands (proximity of the learning object, proximal or distal), conditions for learning (affordances for and constraints on learning); and motivation or purpose of activity. The re-conceptualized organizing circumstance of learning, then, offers a methodological and theoretical way to redefine context and understand how learners manage their own learning.

The main focus of this thesis is on the effectiveness of project-based learning (PBL) in engineering design. The literature review has shown that there is much confusion and ongoing arguments concerning the implementation of PBL in engineering design, and there lacks consensus on its effectiveness. Little research has been done on providing measurable metrics of PBL effectiveness, not to mention discovering the optimal PBL and its underlying mechanisms based on solid educational theories and rigorous research methodology. In this thesis, the measurement of the optimal PBL effectiveness (effect) is studied and a theoretical model of PBL is built in order to identify parameters (cause) controlling the effectiveness and to study the interplay between effectiveness and the parameters. The model is built through three main phases, with a combination of qualitative and quantitative research methods. In phase one, the effectiveness of PBL is studied from the perspectives of the engineering design lecturers and engineering graduates by interviews, which is used to represent effect (Y axis) of the model. In phase two, on the basis of self-directed learning theory (SDL) and learner engagement theory,two key parameters of PBL, i.e. SDL and learner engagement, are identified and quantified respectively to represent cause (X axis) of the model. With the key parameters of PBL (X axis) and PBL effectiveness (Y axis) obtained, a theoretical model of PBL is proposed. The model is verified by means of experiments (student self-reported surveys). A specified Moving Average Method (MAM) is used for data analysis and findings demonstrate different trends of the relations between SDL and PBL effectiveness, and between learner engagement and PBL effectiveness. Consequently, a 3D model of PBL is built by combining the data in aforementioned 2D models,through which the optimal PBL effectiveness in 3D are identified and measured and the interplay between different parameters are found. In phase three, in order to find out more delicate features in PBL ignored by MAM, the dynamic interaction of individual differences in PBL teamwork is explored by the ethnological method (including participant observations and interviews), which is conducted as a supplement to the model of PBL. The theoretical model of PBL effectiveness proposed in this thesis is novel and groundbreaking. Firstly, a series of 2D and 3D models are presented and the relations between SDL, learner engagement and PBL effectiveness are revealed for the first time, which provides guidance for the optimal PBL measurement and implementation. Secondly, a qualitatively-quantitatively-combined strategy is used to discover the mechanisms controlling optimal PBL at different scales. Thirdly, the experiments verifying the model provide fresh quantitative insight into optimal PBL. In summary, the research in this thesis opens up a new research methodology for studying PBL effectiveness, which makes contribution to the educational field as well.

Ways in which educational structures can initiate and facilitate older learners' self-directed learning projects are described in this study. The research was guided by questions related to the ways that educational organizations can facilitate the learning process for older learners. This study involved two distinct phases of research. In the first phase, a survey was administered to approximately 100 older learners at four organizations for senior citizens; the four organizations were Hillcrest Center for 55+, Golden Learning Opportunities and Workshop, Tulsa Senior Services, and Retired Senior Volunteer Program. The survey enabled the researcher to identify the 10 most frequented sites for gathering information related to the learning projects of senior citizens in Tulsa, Oklahoma. The survey respondents were volunteer participants from classes, social occasions, and other learning opportunities offered by the organizations. The survey produced three sites where older learners pursued learning activities. Phase two involved ethnographic techniques in order to identify and describe at each three sites specific educational structures that facilitated older learners' self-directed learning projects. The descriptions from each of the identified sites involved three data-collection techniques. The data-collection techniques used included interviews, observation, and artifact collection. The focus of this phase was to describe the educational structures that facilitated the development of learning projects endemic to each site as identified by the older learners. Notes taken during interviews and observations were transcribed, coded, and analyzed. Interviews were also transcribed. The transcripts were transferred to a conceptually clustered matrix for each site. Analyses of the administrator interviews, participant interviews, educational opportunity observations, and artifact collection at each site revealed patterns and trends that represent the educational structures that appeal to older learners as they pursue learning projects. The findings indicate that four patterns or trends were common to each site. These four patterns included accessible materials, service-minded staff, entertainment, and teacher-directed learning style.

This study examined the relationship between the sub-components of Holland's Self-Directed Search and independent, objective measures of ability using a comprehensive battery of well-validated tests of primary abilities corresponding to each of Holland's six vocational interest types. The sample consisted of 149 female undergraduate students, ages 18-25. Correlation of the ability measure test scores with the four Self-Directed Search subcomponents revealed that the subtests were not related to corresponding measures of ability in a consistent fashion. Implications for the use of the Self-Directed Search in assessing abilities are discussed along with suggestions for future research investigating the relationhip between interest in ventories and the measurement of primary abilities.
