An Embedded Constraint-based Tutor for Onthe-JobTraining

Abstract

We present Chreos Tutor, a constraint-based tutor embedded into Chreos, an existing business software system. The goal of Chreos Tutor is to teach users new to Chreos how to complete realistic tasks. In Chreos Tutor, the student interface is the combination of a new tutoring screen and existing Chreos data input screens. We conducted a study investigating the effect of feedback Chreos Tutor provides, which shows that the feedback resulted in a significantly higher learning gain. An experienced Chreos user found the tutor to be a preferred training option for new users.
