Armed with the profiles that they have built up, students go to this ActiveHistory Simulation which asks them a series of questions about what they think they now know about the personality and appearance of the Ripper. The computer then analyses their responses to present them with a list of the most likely suspects based on their preferences. The simulation also asks a series of factual questions as it progresses and gives them a score at the end. A worksheet accompanies the simulation, which also brings in fresh evidence such as the 1988 FBI profile, the 2006 EFIT profile and the coroner’s reports. The simulation should occupy at least 30 minutes, and the follow-up debate a similar amount of time.
