If you can see it and hear it on the computer then what more can you ask for? A teacher could be standing in front of students saying the exact same thing that a manipulated character on the screen and chances are they will remember the manipulated image rather than the teacher. But why? For one thing a teacher is real, obviously but an image that is not seen in the every day classroom lingures on a persons mind, it is memorable and so is the information it is discussing. How do you get a student motivated, engage them in their learning by creating alternative paths. Students all learn different ways, some are audio learners, some visual, some learn better hands on. Which ever form of learning is required one thing is for certain, by giving them something different and aberrant you are increasing their chances of with holding that information.
