Problem-based learning (PBL) is a powerful instructional design for professional education, which may be used to guide the design of interactive multimedia (IMM). An IMM package incorporating PBL principles has been developed to assist teachers in learning to integrate information and communications technologies (ICT) into their teaching. The development process became a PBL experience for the author as design and implementation issues were met and resolved. This article describes how the learning that occurred has influenced the final form of the multimedia materials and discusses how the PBL principles were implemented in IMM. (Contains 1 figure.)
