Exploring National Certificate Vocational (NCV) level two learners’ misconceptions in algebraic functions through integrating GeoGebra during teaching and learning

This study focuses on exploring NCV level two learners’ misconceptions in algebraic functions through integrating GeoGebra Dynamic Software during teaching and learning. The research investigates how the integration of GeoGebra during teaching and learning algebraic functions influenced learners’ misconceptions in algebraic functions. Vygotsky’s sociocultural view of learning underpinned the process of teaching and learning during the study. The research was carried out at the TVET College in Port Elizabeth. The data was collected by means of pre-test and post-test, focus group interviews, GeoGebra intervention and observations. Created GeoGebra applets and a worksheet was used during the integration process. The data collected was analyzed and used to answer the research questions of this study. Research findings showed that the integration of GeoGebra during teaching and learning enhanced learners’ conceptual understanding in algebraic functions. There was a significance increase in the number of learners who showed ability to interpret algebraic functions based concepts after the engagement with GeoGebra applets

Creation of Innovative Teaching Spaces with Gamma Tutor: A Techno-Blended Model for Rural Mathematics Teaching

Innovative techno-blended teaching methodologies are needed for 21st-century classrooms. This paper reports on the introduction of a techno-blended device for mathematics teaching in South African senior secondary classrooms. The research sample included 12 third-year mathematics education student teachers from a rural university. A qualitative case study design was employed. Participants were purposively selected. Data collection methods included non-participatory observation and in-depth individual interviews. The TPACK model and the Mathematical Knowledge for Teaching Framework guided the analysis of the data. The study found that the mathematics student teachers successfully implemented GammaTutor in their classrooms, thus demonstrating their proficiency and aptitude in utilising technology in the learning environment. The GammaTutor device also aided in teaching and learning mathematics by simplifying mathematical ideas for learners. Furthermore, it enabled the development of learner discourse as a crucial component for developing learners' problem-solving skills. Since the mathematics student teachers engaged the learners with a variety of mathematical exercises using the GammaTutor technology, the integration of GammaTutor in the mathematics classroom exhibited learner-centred provisioning. The study proposes a teaching model for creating innovative teaching spaces in rural schools in South Africa
