Background: The study focused on children with hearing disabilities, which was significant as almost 9 million children in sub-Saharan Africa, including Namibia, had hearing disabilities. The problem was the lack of prior research on the effects of assistive technology (AT) in primary education for the Deaf in Namibia, for guiding Namibian special primary schools and educators.Aim: The aim was to investigate the effects of Constructivism-led AT on the teaching and learning of learners who were deaf, in a mathematics class at a rural special primary school.Setting: The study involved Grade three children who were deaf. Grade 3 is where children learn to build and understand foundational and basic mathematical concepts, such as counting, which they require for subsequent mathematics learning and practice.Methods: The study was a mixed-methods study comprising a quantitative experiment and qualitative interviews.Results: The findings suggested that the Constructivism-led AT may have had a positive effect on the children’s multiplication and division achievement, but not on their addition and subtraction achievement. The teachers were positive about the Constructivism-led AT and indicated that it supported collaborating, cooperating, exploring, self-assessing, learning from errors, seeking knowledge independently, self-regulating, self-reflecting, metacognitive thinking and being self-aware.Conclusion: For school management and teachers of children who are deaf, the study offered an intervention for potentially improving teaching and their learners’ mathematics achievement. In addition, the study provided valuable evidence for policymakers about integrating technology for effective learning environments.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
