- Description: Radiographers use ionising radiation to produce radiographic images and the use of ionising radiation in healthcare has both benefits and risks for patients and healthcare professionals. It is therefore important that radiographers mitigate the risks associated with ionising radiation. It is for this reason that radiation protection measures are applied to ensure the safety of patients, staff, and the public. Furthermore, radiographers are also responsible for mentoring radiography students and inculcate the use of radiation protection measures when students undergo their workplace learning. This mentoring takes place in the clinical setting with its characteristics that may or may not advance the application of radiation protection measures. The aim of this study was to investigate the lived experiences of final-year undergraduate radiography students applying radiation protection measures in the clinical setting and to propose strategies to foster the integration of radiation protection theory into clinical practice. This study was located in the interpretivist paradigm using phenomenology as a research method and theoretical framework to achieve the stated aim. The target population for this qualitative study included all registered final-year undergraduate radiography students at the local university who perform their WPL at the accredited training hospitals in the Eastern Cape Province as this cohort of students have more clinical experience than the first-, second- and third-year students. The target population comprised 28 students. Purposive sampling was employed to select the group of radiography students to interview. The study used phenomenological interviews as a data collection tool and the collected data was explicated using a self-developed method. The trustworthiness of the study was ensured by applying Guba’s model of trustworthiness that includes credibility, transferability, confirmability, dependability and authenticity and was further enhanced by reflecting on the balanced integration, openness, concreteness, and resonance of the study. This study employed an ethical framework referred to as principlism that includes the notions of autonomy, beneficence, non-maleficence and justice.Data explication was conducted using three cycles of explication. Cycle one produced interpretive profiles for each participant. The interpretive profiles revealed the life histories of each participant as well as the utterances of participants related to the three sub-questions. Cycle two produced four themes. Theme one described participants’ being with others such as radiographers, clinical supervisors, medical doctors, and patients and revealed the tension between participants’ belonging and being unwanted. Theme two characterised the clinical setting as a place where several factors flow together to provide participants with their individualised experiences. Theme two revealed the emotional distress; the learning through trial-and-error; the independent learning; learning that is coupled with humiliation as experienced by participants. The clinical space was also characterised as a place to be survived, a place where students have to be inconspicuous and understand the acceptable levels of engagement with others. It is also a place where theory and practice at times is in alignment at other times not in alignment. The clinical setting could also be a place of self-doubt and insecurity, a place of personal growth, and a place where historical events are significant. Theme three disclosed the unspoken lessons that were conveyed through the actions and behaviours of individuals in the clinical environment. Unintended lesson one is that radiation protection measures are not important. Lesson two suggest that classroom teaching about radiation protection is not valid in the clinical setting, and finally that incivility towards radiography students is acceptable. Theme four revealed the difficulties experienced by radiography students when navigating ethical dilemmas. The theme revealed radiographers’ and radiologists’ indifference towards radiation protection, the non-application of radiation protection measures, and the inconsistency and apathy towards radiation protection measures. Cycle three viewed the experiences of participants through the lens of Dasein’s disclosedness. This revealed the exclusive language used by participants, the largely negative mood and participants’ disconnection from the imaging department.Finally, the study presented new and important insights by probing the topic of radiation protection in a novel way by using phenomenology to focus on the lived experiences of final-year undergraduate students applying radiation protection measures in the clinical setting. The findings of the study also allowed for the development of Enhancement strategies that could be used by institutions of higher education to promote the integration of the theory and practice of radiation protection measures in the clinical setting. It is recommended, though, that a study that includes all South African institutions of higher learning offering radiography be conducted using phenomenology. Furthermore, the views of South African radiographers and clinical supervisors should also be elicited to corroborate the views of participants in this study. , Thesis (PhD) -- Faculty of Education, School of Secondary Education, 2024

- Description: The success rate of students in higher education has been a cause for concern in South Africa (Letseka & Maile, 2008; Department of Higher Education and Training, 2015). This has been particularly concerning for first-year students, where the rate of attrition is especially high (Letseka, Cosser, Breier, and Visser, 2010). A number of factors have been identified in past research as having an effect on academic performance, which influences attrition and graduation. These factors include age (Justice, & Dornan, 2001), gender (Buchmann, & DiPrete, 2006), socio-economic status which is confounded by race (Letseka & Breier, 2008), type of educational background (Spreen, & Vally, 2006), and whether a student is a domestic or international student (Li, Chen, Duanmu, 2009), social capital (Young & Strelitz, 2014), whether the student is a first language speaker of the language of instruction at the university (Snowball, and Boughey, 2012), student wellbeing (Quinn, & Duckworth, 2007), locus of control (Findley, & Cooper, 1983), and frequency of lecture attendance (van Wallbeek, 2004). The study was conducted at Rhodes University, a small historically white South African institution. For this study, academic performance was measured using the participant’s midyear exam results for an introductory psychology cause, a course that straddles faculties. Of the 690 students registered for the course, 361 (52%) completed an electronic survey that explored the various factors associated with academic performance. A hierarchical regression analysis indicates that pre-university factors (age, gender, race, nationality, language, type of school, and socio-economic status) were the only significant predictors of academic performance, contributing 11% of the effect. Race and nationality, when all the other factors were controlled for, were the only predictors of academic performance. The implications of these findings pose troubling questions of the institutional culture at the university.

- Description: The pervasive presence of cellphones in the lives of urban young people around the globe has led to widespread research to evaluate the impact that this device has on young people’s overall psychosocial development. This relationship is often characterised as “addictive”. This research study presents a unique South African youth perspective in a field of research that is predominantly conducted in the United States, Europe and Asia. It explores the relationship that students (ages 18–21) at Rhodes University have with their cellphones in order to understand how this device informs their experience of social participation online and offline. Central to the design of this study is a “social media detox” which involved the research participants volunteering to restrict their social media and cellphone use for an agreed-upon period of time. The study employs interpretative phenomenological analysis (IPA) to uncover key themes from in-depth interviews before and after the detox. Eight respondents were interviewed twice; once before and once after their detox. This study provides insights into the integral role of a cellphone as reported from a young adult’s perspective. Communicating on social media platforms using a cellphone has become normalised among this age-group and the respondents described how the cellphone feels like “a part of you”. Unlike interacting face-to-face which is potentially awkward and involves effort, socialising on a cellphone offers the respondents a sense of companionship, control and instant access to their peer groups. The respondents in this study seemed unaware of their own agency in social situations until their participation in the social media detox. By participating in this study, the participants became more aware of how their cellphone use influences social behaviour, both online and offline. The study proposes that the term “addiction” undermines the positive association young people have with their cellphones. Instead, this study suggests that “social fitness” would be a more relevant construct through which to encourage and support young people to exercise agency in their social lives. This exploratory study raises new questions for researchers, programme developers and educators to take up in future studies and programme development

- Description: This study explores the potential for critical pedagogical innovation to expand student learning activity, meaning making and learning agency of first year undergraduate students. The study is located in a larger critical project. Rather than looking to support ‘unprepared’ students to better adapt to the current culture of higher education, the larger critical project looks to the generative potential of new students to elaborate the structure of higher education itself over time. The study emanates from a process of reflective self-critique of one higher education institution in South Africa serving a student population with little access to educational advantage. The emerging critique was located at the interface of institutional practice, student learning activity and the meaning making processes mediating the two domains. This critique gave birth to the pedagogical innovation at the centre of this study. The pedagogical innovation took the form of an activity system, with three sets of pedagogical tools mediating the system: tools to expand the learning practice of students, symbolic tools to expand the critical meaning making toolkit available, and tools designed to build a new learning community better aligned with interactive learning activity. This study is an intervention case study, theoretically grounded in the work of activity and socio-cultural theorists. The pedagogy was embedded within a semester long credit-bearing core course for entering first year students. The study follows the experience of the 652 students participating in the 2010 pilot experience. Upwards of 70% of students suggest that their reading (76%) and writing (71%) practice had changed by the end of the course. Over 80% indicated that the course made them better readers (85%) and writers (84%.) Students suggest that they read and write more and enjoy reading and writing more. They suggest that as motive expanded, activity of reading and writing expanded, complimentary activity expanded (e.g. expression and critical engagement), and participation across a number of domains expanded. Students with less historical access to educational advantage made stronger claims about the pedagogical toolkit than students with more access to educational advantage. This study suggests that under the right conditions, critical pedagogy focusing on student learning activity and meaning making can expand learning practice and meaning making of first year undergraduate students, contributing to an expanding claim on learning agency. It tentatively suggests that this type of learning architecture is well aligned for appropriation of students with less access to historical socio-educational learning privilege, but remains sensitive to the situated nature of historic disadvantage (for example, in campus sites.) The study points to the specific potential of three toolkits: toolkits to mediate expanded learning activity, toolkits to expand meaning making, and toolkits designed to directly reconstitute the learning community itself. The study concludes by extracting some lessons for critical pedagogical innovation serving first year studies into the future. It points to the importance of the domain of learning activity and meaning making, and suggests the kind of changes within the culture of higher education required to better unleash innovation in this area. It points to the generative potential of methods that better combine students and lecturers within pedagogical innovation processes. The study concludes by pointing to the relatively unoccupied area of critical research, whereby the work to expand the learning activity of first year students is aligned to the potential of students to elaborate the structure of higher education itself over time. The study points to three specific research areas: research building stronger pedagogical tools for first year students; research to better understand the critical meaning making project of students; and research to better understand the transformation of the pedagogical inheritance within higher education.
