Higher education institutions (HEIs) in Africa face the challenge of responding to the expanding demand for tertiary education while maintaining or enhancing the quality of their course offerings. This demand has led to some HEIs introducing the use of interactive web technologies to support their distance teaching and learning practices. However, academic staff at these institutions may struggle to provide sufficient support to online learners in part due to inadequate staff capacity in terms of familiarity with and use of online communication tools and virtual learning environments. This paper reports the design and development of an openly licensed capacity-building intervention and the piloting thereof with academic staff at three southern Africa educational institutions. The aim of the capacity-building intervention is to initiate skill development and introduce foundational concepts in support of engaging online learners. The design and development of the course material is discussed, and the experiences of the pilot delivery are examined.
