Despite significant capability deprivation existing among the teachers in historically disadvantaged schools in the Western Cape province of South Africa, information and communication technologies (ICTs) have had a significant positive effect on teaching and learning. In the case study reported on here we investigated the benefits of using ICTs by public primary school teachers in teaching and learning. Sen's capability approach was used to frame this study. We employed a qualitative research method in which 8 teachers were involved in lesson observations and semi-structured interviews. The findings reveal that, to some extent, through the teachers' use of ICTs (commodities) in smart classrooms, the influence of personal conversion factors (ICT skills obtained through a community of practice and university training), had created the capabilities for teachers to use ICTs for curriculum delivery, although to a limited extent. Through this process, teachers benefited with specific vital achievements. From the study we recommend that holistic and annual professional development training programmes should be made mandatory for both novice and seasoned teachers.
