Objective: The study investigates first-year teacher education students' self-directed learning through Computer-Aided Mathematics Instruction (CAMI). Methods: A total of 230 first-year mathematics teachers specialising in Further Education and Training (FET) phase teaching participated in the study, where responses from 50 student teachers were purposively and conveniently selected to report on in this paper. A qualitative research method approach was used and open--ended questionnaires were utilised to collect the data for first-year teacher education students' self-directed learning. The questionnaires were analysed using descriptive data analysis. Results: Results of the study revealed that CAMI was used to monitor students' learning, the time the learning takes place, the performance of the student within the duration of time, and to evaluate student performance. The results also revealed the skills that characterised self-directed learning and active learning where the student teachers were motivated to learn more and to solve difficult problems in mathematics. Conclusions: The study recommends technology integration, such as CAMI, in teacher education and teaching and learning in the Higher Education Institutions (HEIs), to promote self-directed learning and support effective learning for future learners.
