The use of objects within the classroom and workshop sessions is an invaluable way of increasing participation and generating conversation. Objects can act as focal point for learning or can be used in a more abstract manner to generate ideas. This session will explore the use of objects as an engagement and learning tool in both large and small group settings. 3D printed artefacts, parts of instruments and printed images will be used to explore structure and function, generating discussion and acting as stimulus to prompt conversation. In this session the practical aspects of the use of objects in large and small group teaching will be addressed alongside the pedagogical basis of the learning theory.
