Introducing the first app of its kind! ID-SIM, short for “Instructional Design of a Simulation Improved by Monitoring”, is an extensive tool to assess the quality of (medical) simulation training courses. With use of questions in 10 different categories, the ID-SIM creates an innovative Prop Chart, providing both an overview and detailed information about the instructional design of the training course. The results are easily exportable via email, giving the opportunity to integrate into Powerpoint, Keynote or other programs.
