Learning resources such as audio, video and online content are developed as supplementary learning resources to print-based materials. This study focuses on the development of multimedia learning in adult education programmes for out-of-school girls and young women in Tanzania. It defines multimedia and adult education before showing the relationship between them. The study used a descriptive paradigm and adopted a qualitative case study design. It is informed by 25 in-depth interviews that were conducted with Institute of Adult Education (IAE) facilitators in April, 2018. Participants were purposely selected based on their multimedia experience. The findings revealed that most facilitators have little experience in multimedia resource development. However, 13 self-instructional audio and audio-visual programmes were produced to elaborate and enhance the effectiveness of instructions. It will be argued that IAE should include development and use of multimedia resources in its strategic rolling plan. Learning material development policy should also include multimedia resources and create awareness.
