Blended learning in orthodontic diagnosis: an interactive approach.

Interactive multimedia programs can provide an opportunity for authentic learning both inside and outside the classroom. McGill University designed an interactive Orthodontic Diagnosis program on CD-ROM that has been used successfully in the faculty of dentistry to provide undergraduate students with interactive tutorials and exercises to help them recognize developing malocclusions. Key aspects of this multimedia program are the use of an outside-in approach to diagnosis as well as sound instructional design that provides practice opportunities and feedback to students. The goal is to bridge the gap between theoretical knowledge and the practical skills needed to be a successful dentist.
