If you are reselling to clients, GeMS is configured for the number of learners and number of courses. A regular expression provides a structure for representing several possible inputs in a compact form. This technique generates far more possible solutions than the human mind can generate. The learner can be forced down a path in their course by only using one goal and not pretesting the learner. Research has shown that learners are more receptive to learning when they have some level of control.
Every learner has their own preferences or learning style.
In addition, one of the major benefits of eLearning is to allow the learner to refresh or review certain topics, which does not lend itself to a specified or limited path approach. Feedback is a very effective learning technique when designed to be specific and directly related to the response provided by the learner. It should be informative and motivating. If the learner's response is incorrect, the feedback should lead to discovering why it was incorrect and what the learner needs to do to make the response correct on the next attempt. If the learner's response is correct, ideally the feedback should lead the learner to additional instructional experiences.
