Digitalisation is widely promoted across Sub-Saharan Africa as a pathway to educational improvement and human development, yet its developmental impact remains uneven due to persistent gaps in teachers’ digital pedagogical competence. This paper argues that teachers occupy a strategic position at the intersection of digital education, equity, and human development. Drawing on human capital theory and the capability approach, it demonstrates how teachers’ effective integration of digital tools into curriculum design, instruction, assessment, and inclusive practice is essential for fostering learners’ skills, agency, and life opportunities. Evidence from Sub-Saharan African countries, including Nigeria, Ghana, Kenya, Rwanda, and South Africaindicates that although access to educational technologies has expanded, many teachers lack the confidence and practical capacity to use them pedagogically. Inadequate pre-service and in-service training limits the development of critical thinking, collaboration, creativity, and problem-solving skills, particularly among disadvantaged, rural, and marginalised learners. The paper advocates repositioning teachers as central agents of digital transformation through the systematic integration of digital pedagogy into teacher education, sustained practice-oriented professional development, and meaningful inclusion of teachers in policy design. Strengthening teacher capacity, it argues, is critical for moving beyond superficial technological adoption toward inclusive and sustainable human development outcomes in Sub-Saharan Africa.
