- Description: Visualisation in the mathematics classroom has its own pedagogical value and plays a significant role in developing mathematical intuition, thought and ideas. Dynamic visualisation possibilities of current digital technologies afford new ways of teaching and learning mathematics. The freely available GeoGebra software package is highly interactive and makes use of powerful features to create objects that are dynamic, and which can be moved around on the computer screen for mathematical exploration. This research study was conceptualised within the GeoGebra Literacy Initiative Project (GLIP) – an ICT teacher development project in Mthatha in the Eastern Cape, South Africa. The focus of this study was on how GeoGebra could be used as a teaching tool by harnessing its powerful visualisation capacity. In the study, selected GLIP teachers collaboratively developed GeoGebra applets, then implemented and evaluated them. The research methodology took the form of action research cycles in which the design, implementation and evaluation of successive applets determined the data gathering and analysis process. My data consisted mainly of recorded observations and reflective interviews. The underlying theoretical foundation of this study lies in constructivism, which aligned well with the conceptual and analytical framework of Kilpatrick et al.’s (2001) description of teaching proficiency. An in-depth analysis of my classroom observations resulted in multiple narratives that illuminated how teachers harnessed the visualisation capabilities inherent in the software. My findings showed that dynamic visualisation and interactivity afforded by the use of technology are key enabling factors for teachers to enhance the visualisation of mathematical concepts. My analysis across participants also showed that technical difficulties often compromised the use of technology in the teaching of mathematics. The significance of this research is its contribution to the ongoing deliberations of visualisation and utilisation of technological resources, particularly through the empowerment of a community of teachers. The findings recognised that the integration of technology required appropriate training, proper planning and continuous support and resources for the teaching of mathematics. This action research provided insightful information on integrating Dynamic Geometry Software (DGS) tools in mathematics classrooms that could be useful to teachers and curriculum planners. , Thesis (PhD) -- Education, Education, 2021

- Description: This study examined how the establishment of leadership development programme targeted at female learners in primary schools could promote female learner leaders and motivate more women to take up leadership positions to address concerns of gender and to prepare females for the challenges they may face when assuming leadership roles in future.Whereas adolescent girls may be the future representation of women leaders in society, leadership development of female learners in primary schools has been neglected. Currently, a review of literature on the problem of gender imbalance at leadership level reveals a dearth of research among the youth, less so, among young women. Yet, globally, in Africa and in South Africa, particularly, there is an inequitable balance of leadership positions in society when comparing men and women. The researcher has identified this gap and has decided to dedicated research efforts in adolescent leadership development to enrich the scant existing knowledge on the born-global phenomenon. Because schools play an important role in student development and schools are a key resource for achieving equity goals, understanding how leadership is promoted by school teachers is an important step toward growing the literature on female learners’ leadership development. The study was based on five primary schools in the Amathole District in the Eastern Cape Province, South Africa. The study followed a qualitative research approach where interviews were employed to elicit data from the study’s participants and to help in understanding the phenomenon under study. A non-probability, purposive sampling technique was used where ten participants were selected. The study’s participants were five (5) principals, two (2) HoDs, two (2) post level 1 teachers and one (1) Learner Support Assistant (LSA). The study found that a paradigm shift from the traditional view of leadership, where young people are not given leadership positions because they are regarded as young or quiet is a patriarchal belief system that should be done away with. Instead, role-players should embrace and encourage female children to be transformational and servant leaders. There is need for a change of mind-set from all role-players in South Africa to accept learners as equal participants in school leadership and to prioritise the training and development of female learner leaders. Female learners need to be taught a broader understanding of leadership as a concept including differing leadership theories and styles. Leadership as a concept needs to be taught early in primary school and to all learners. The study recommended leadership development seminars, camps, workshops and guest speakers that could aid in the development of leadership at primary school, and to be prioritised. The study concluded that continuous leadership training from a young age, for all learners in primary schools should be encouraged to ensure that learners chosen to lead assume leadership roles with confidence, skills and experience. Government schools need to allocate budget for leadership development of learners, with special funding for the relatively disadvantaged gender. , Thesis (DPhil) -- Faculty of Education, 2020
