This chapter introduces a case study to explore the pedagogical re-design of an online module using online discussions as the focus for learning. A longitudinal and development module assessment was threaded through three phases of learning: 1) writing bees, 2) WIKI (what I know is), and 3) problem-based learning (PBL). Each phase of learning is explained using evidence to support its development, and a critique of the benefits and limitations of learning this way is included. An evaluation of the re-designed module is included, demonstrating although at times the online discussion and writing activities were challenging that on the whole, students enjoyed learning in this way. This chapter concludes by claiming that the pedagogical design of learning using online discussions should be engaging, interactive, collaborative, and fully supported at every stage of the learners' journey and recommends further research in the theory of communities of practice to inform such pedagogical design.
