7th ANNUAL INNOVATIONS IN E-LEARNING SYMPOSIUM Presentation. Do 3D graphics and interactions really make a difference in how a learner interacts with content or other learners? Is a 2D environment as effective for serious games as a 3D environment? Studies are beginning to reveal the elements that make 3D characters more engaging and intriguing to learners. Additionally, research has indicated that the interactions learners have with 3D characters have an impact on behavior both within the 3D environment and for some time after the learner leaves that 3D environment. It turns out that 3D does make a difference in terms of learning, motivation and impact on behavior. This session discusses research that supports the argument that 3D learning environments add additional cues and inputs that make them ideal for teaching certain types of content.
