Constructivist Assistive Technology in a Mathematics Classroom for the Deaf: Going Digital at a Rural Namibian Primary School

Within the context of almost nine million children with hearing disabilities in Sub-Saharan Africa, their education is an important topic. The problem was the lack of conclusive research about the effects of digital assistive technologies for educating deaf learners in Sub-Saharan African countries, such as Namibia. The question was could a digital assistive technology improve the mathematics achievement of deaf children? The research objective was to gather scientific evidence by conducting a quantitative experiment with constructivist digital assistive technology and qualitative interviews with the teachers involved. The findings from the experiment suggest that the constructivist digital assistive technology may have had a positive effect on the mathematics achievement of the learners, which was supported by the findings from the interviews. This makes an original contribution to the domain and offers an intervention that was feasible, practical and potentially effective for improving the teaching and learning of mathematics for deaf learners.
