Teachers' understanding and use of digital play for language acquisition in Grade R

Van der Westhuizen, Leonie Magdalena 11 1900 (has links)
Teachers tend to use traditional teaching methods, even though young learners are more digitally oriented. The purpose of this study was to analyse teachers' understanding and practices in grade R classes to clarify their use of digital play for language acquisition. The participants consisted of eight grade R teachers at one selected primary school in an urban area that had access to digital technology. Bronfenbrenner's ecological systems theory as a theoretical framework informed this study. This qualitative single case study generated data from teacher participants and their interaction with the learners. The data generation included semi-structured individual interviews, focus group interviews, and non-participant observations. Analyses to answer the research questions were conducted by means of thematic analysis. The main finding was that grade R teachers have some knowledge and understanding of digital play and they are willing to try new games, but they feel they need to know more about digital technology and the use of digital games for language acquisition. Recommendations include the need for the development of more digital games relevant to language acquisition and for teachers to adopt relevant pedagogies to benefit from available digital games. A similar study in a rural area and a comparison between this study and such a study will then be useful in determining teachers' understanding and use of digital play for language acquisition. / Onderwysers is geneig om tradisionele onderrigmetodes te gebruik, selfs al is jong leerders meer digitaal georiënteerd. Die doel van hierdie studie was om onderwysers se begrip en praktyke in graad R-klasse te ontleed, om hul gebruik van digitale spel vir taalverwerwing duidelik te maak. Die deelnemers het bestaan uit agt graad R-onderwysers by een uitgesoekte laerskool in ʼn stedelike gebied, met toegang tot digitale tegnologie. Hierdie studie is geïnspireer deur Bronfenbrenner se ekologiese stelselteorie as ʼn teoretiese raamwerk. Hierdie kwalitatiewe enkelgevallestudie het data van onderwyser-deelnemers en hul interaksie met die leerders gegenereer. Die datagenerering het halfgestruktureerde individuele onderhoude, fokusgroeponderhoude en niedeelnemer-waarnemings ingesluit. Die vernaamste gevolgtrekking was dat graad R-onderwysers oor ʼn mate van kennis en begrip van digitale spel beskik en dat hulle bereid is om nuwe speletjies te probeer, maar hulle voel hulle behoort meer te weet van digitale tegnologie en die gebruik van digitale speletjies vir taalverwerwing. Aanbevelings sluit in: die behoefte aan die ontwikkeling van meer digitale speletjies wat op taalverwerwing betrekking het; en dat onderwysers tersaaklike pedagogieë moet inspan om uit die beskikbare digitale speletjies voordeel te trek. ʼn Soortgelyke studie in ʼn landelike gebied en ʼn vergelyking tussen hierdie studie en so ʼn studie sal dan nuttig wees om onderwysers se begrip en gebruik van digitale spel vir taalverwerwing te bepaal. / Barutiši ba na le go šomiša mekgwa ya sekgale ya go ruta, le ge e le gore baithuti ba baswa ba na le tsebo ya theknolotši.
