It was about one and a half years ago that I finally I arrived where I had always wanted to be and do what I had always wanted-- teach students, support small language communities and conduct research on African languages on my doorstep. The University of Cape Town and my new colleagues welcomed my efforts to establish the Centre for African Language Diversity-- CALDi as well as The African Language Archive-- TALA and I was recently appointed the Mellon Research Chair: African Language Diversity this initiative. The main aim of CALDi is to train young African scholars in descriptive linguistics and open up space for research into African languages at UCT with the hopes of countering the dominance of African linguistics outside the continent. It has been a great challenge for which my whole career has been a form of preparation...Read more

What do meta-analyses tell us about CALL effectiveness?
A great deal of research has been carried out over the past two decades related to the effectiveness of computer-assisted teaching and learning. This large body of work, however, has not produced unequivocal findings, especially in the
area of CALL. Our study takes a systematic look at what dedicated meta-research since 1991 might have contributed to this controversial field. Data was gathered from several hundred studies including ca 20,000 subjects. The paper highlights the benefits and limitations associated with this type of research, synthesizes findings and recommends models and strategies for future research in the context
of an agreed research agenda. Our synthesis suggests consistent positive findings related to L1 spelling, writing and reading. While there is some support for this related to CALL per se, much work needs to be done before we might reach the levels of confidence enjoyed by some of the findings reported here.
