Abstract In this article, we focus on the features and functions of the STEP pbl system that enable us to support novice tutors and thereby address the human resource challenge that implementing a PBL course in a typical undergraduate setting poses. We describe the activities that students in our course engage in and present preliminary findings from our first trial of the system. We then describe our strategies for distributing the functions of the tutor based on the first trial and previous course implementations. We conclude with a description of the research methodology we are using to shepherd our site development efforts.
