Knowing how campus-based students engage in key online and general learning practices can play a central role in managing and developing university education. Knowledge in this area is limited, however, despite recent advances in student engagement research, and widespread adoption of online learning systems. This paper responds to the need to develop such knowledge, by documenting the development and application of a typological model of online and general campus-based student engagement. It reports the statistical analyses used to develop the model, and analyses the model's structure and substance. The model is exemplified by considering what it says about how increasingly powerful and pervasive online technologies might be leveraged to enhance campus-based student engagement.
