Abstract Educational use of new technologies can transform online learning through the inclusion of interactive learning-environments. In Agriculture at Iowa State University, we apply game-based learning to introduce undergraduate learners to the microbiology world. This 15-minute showcase presentation will demonstrate two types of game-based learning modules: text-based game learning module before re-design, and more interactive game design module with the help of Storyline and embedded 3D models. Participants will have opportunity to explore both modules, followed by a short discussion on how games can enhance teaching and learning effectiveness.
