One approach used in teaching scientific principles is laboratory practical classes. However, it can be challenging to teach concepts prior to their introduction in lectures. Academic teaching staff that wish to use alternative approaches to bridge this gap and, in turn, enhance student learning, often require help from their local Educational Developers (EDs). This chapter outlines the process of identifying a problem and then developing, implementing, and evaluating an online interactive simulation to teach enzyme kinetics to undergraduate students at the University of South Australia (UniSA). The challenges faced by the academic and ED in developing the simulation are covered. By the end of the chapter, the reader (academic or ED) will have a better appreciation of the challenges faced in developing a new teaching approach as well as the strategies that can be used to address these challenges.
