Using technology to persuade people to behave in a certain way is an ever-increasing field of study. The ability to persuade individuals is quite clear in e-commerce, where individuals are persuaded to make purchasing decisions. However, it can also be applied to other disciplines, such as education where improving the study behaviour of students would be particularly useful. Forming good study habits can be a challenge for university students who have not done so in the earlier years of their education, or where the pressures of external commitments have eroded previously good habits. We use a combination of the Fogg Behavioural Model and the Hook model to design features for an app as a component of a larger persuasive system to help improve three key areas of study habits: study scheduling, class preparation and group study. The app will be built and tested in a university setting targeting undergraduate students.
