One of the principal responsibilities of a police officer is to protect a crime scene by spotting and protecting physical evidence at a crime scene.

This prototype lesson was designed for the Justice Knowledge Network to demonstrate various instructional modes, including tutorials, scenarios, on-line testing and a simulation game, that could be used in police training course.

A pre-test provides an advanced organizer to help learners review their knowledge of the subject and preview the course content. It provides immediate feedback after each question. The post-test resembles a traditional exam in that all questions must be answered before the learner submits the exam. Then a final score and feedback on each question is provided.

The tutorials include embedded questions and scenarios. Some of the questions are mixed visual and verbal modes. For example, when answering a question asking where the police office should station his or her vehicle at a crime scene, the learner answers by dragging a police car to one of four different locations on a graphic.

The simulation game presents a quick photographic tour of an elderly lady’s house that may be a crime scene. The police trainee is then tested on his or her recall of details in the scene. This provides the learner with the opportunity to practice an important police skill: making mental notes of a scene that may be used later in an investigation.

These materials were produced for the Justice Knowledge Network, a five-year research and development project to develop e-learning for Canadian police forces.
