Designing training scenarios by rehearsal

A 'rehearsal style' system called PROSPR, designed to aid authors of procedural training material, is presented. While PROSPR is a prototype, it demonstrates the utility of the programming-by-rehearsal paradigm within the context of procedural training. The object-oriented approach helps the programmer and the author to support the mental models between real-world objects and their representations in simulation. The graphical interface allows the procedures created to become a dynamic world where a student can interact with graphical representations as if they were actual objects themselves. Presently the system is best used to train students in procedures which consist of a series of stimulus-response pairs. Each correct trainee action triggers the next simulated screen event.<>
