Coagulationfragmentation dynamics in size and position structured population models.
(2008)One of the most interesting features of fragmentation models is a possibility to breach 
Conformally invariant relativistic solutions.
(1993)The study of exact solutions to the Einstein and EinsteinMaxwell field equations, by imposing a symmetry requirement on the manifold, has been the subject of much recent research. In this thesis we consider specifically ... 
Conservation laws models in networks and multiscale flow optimization.
(2011)The flow of fluids in a network is of practical importance in gas, oil and water transport for industrial and domestic use. When the flow dynamics are understood, one may be interested in the control of the flow formulated ... 
Constructions and justifications of a generalization of Viviani's theorem.
(2013)This qualitative study actively engaged a group of eight preservice mathematics teachers (PMTs) in an evolutionary process of generalizing and justifying. It was conducted in a developmental context and underpinned by a ... 
Convective heat and mass transfer in boundary layer flow through porous media saturated with nanofluids.
(2016)The thesis is devoted to the study of flow, heat and mass transfer processes, and crossdiffusion effects in convective boundary layer flows through porous media saturated with nanofluids. Of particular interest is how ... 
Design model for integrating learning management systems and massive open online courses on a digital eLearning platform: implications for Zimbabwean universities.
(2019)Available affordances for learning provide opportunities for advanced technologyenhanced teaching and learning. Digital learning environments can make relevant learning content available to students using existing ... 
Embedding theorems and finiteness properties for residuated structures and substructural logics
(2008)Paper 1. This paper establishes several algebraic embedding theorems, each of which asserts that a certain kind of residuated structure can be embedded into a richer one. In almost all cases, the original structure has a ... 
Evolving dynamic fitness measures for genetic programming.
(2018)This research proposes dynamic fitness measure genetic programming (DFMGP). DFMGP modifies the conventional genetic programming (GP) approach: rather than applying a single fitness measure individually throughout GP, a ... 
Exact models for radiating relativistic stars.
(2007)In this thesis, we seek exact solutions for the interior of a radiating relativistic star undergoing gravitational collapse. The spherically symmetric interior spacetime, when matched with the exterior radiating Vaidya ... 
Examining computerbased technology skill and academic performance of students in Nigerian universities.
(2019)The introduction of blended learning into facetoface classroom teaching and learning has made traditional education more simple, flexible and customised to students’ expectations. This study examined computerbased ... 
An exploration of General Education and Training (GET) teachers’ mathematical knowledge and its influence on the quality of instruction in the teaching of functions.
(2020)This thesis documents a study of the General Education and Training teachers’ mathematical knowledge of functions and what this knowledge brings to the quality of instruction. The study made use of Variation Theory and ... 
An exploration of preservice teachers use of visualization when teaching and solving problems in the mathematics classroom.
(2020)One of the objectives of mathematics instruction, according to the Department of Education (DoE) in South Africa, and elsewhere globally, is to prepare learners to become proficient in mathematics problem solving. There ... 
An exploration of preservice teachers’ Mathematics knowledge for teaching in Trigonometry at a higher education institution.
(2020)This study investigates the extent of finalyear preservice teachers’ understanding and development of the mathematics knowledge for teaching in trigonometry. Teachers’ lack of adequate mathematics knowledge to teach ... 
Exploring inservice Zimbabwean mathematics teachers’ preparedness to incorporate ethnomathematics approaches to geometry teaching and learning.
(2018)Geometry teachers and learners in Zimbabwe come from a wide range of cultural and social backgrounds. This provides opportunities and challenges in the teaching and learning of geometry. The wide variety of cultural and ... 
Exploring master teachers' use of visuals as tools in mathematical classrooms.
(2011)The teaching and learning of mathematics has presented a great challenge for mathematics educationalists over many decades. Researchers have been searching for new strategies and techniques for improving the understanding ... 
Exploring mathematical activities and dialogue within a preservice teachers’ calculus module: a case study.
(2018)Local and international research findings have shown that high school learners, university students, as well as some of the practicing educators, struggle with calculus. The large numbers of unqualified or underqualified ... 
Exploring teachers’ instructional practices, confidence and beliefs in teaching mathematics and statistics.
(2018)An important contributor to the quality of teaching mathematics is the knowledge of mathematics teachers. In this study, I explore mathematics teachers’ instructional practices, their confidence and beliefs about the ... 
Exploring teachers’ understanding of pedagogic practices in teaching mathematical concepts in grade 1: a case study in South African primary schools.
(2016)The study examines teachers’ understanding of their learning theories on pedagogic practices in teaching mathematical concepts in Grade 1. The study emanates from the findings of the National Education Evaluation and ... 
Exploring university students' mental constructions of the limit concept in relation to sequences and series.
(2019)The present thesis refers to some first semester calculus 1 university students’ mental constructions of the limit concept in relation to sequences and series. A plethora of research on the limit concept is available and ... 
Firstyear engineering students' concept development of integral calculus at a South African university of technology.
(2015)This thesis reports on a study to explore the development of the concept of integration among the first year engineering students at a South African university of technology. The study focused on concept definitions that ...
