Each topic is designed to achieve a specific learning outcome. From the course menu, learners can easily view the entire course outline. Although the course is designed to be taken sequentially, learners are free to take any topic, at anytime. A brief audio introduction explains what the topic is about, what's unique about it and why it is important. Learners then read concise instructions that describe exactly how to carry out the procedure to complete the topic.
Help is never far away.
If learners want to, they can click on the Demo button and see a narrated, animated demonstration of the exercise by the teaching assistant. After they do the exercise, students can click the Check button to have their work checked. If they haven't done the exercise successfully, they can try again or simply leave it and move onto the next topic. To try the exercise again, they can either make corrections or click the Reset button to re-initialize the topic for a fresh start. Most courses include a case study at the end of each lesson.
