Introduction to Course
This course is provided by BBC based in the United Kindom.
The E-learning course is introduced with a spectrum wheel seperated into slices representing different types of injuries.

I thought that by seperating the different types of injuries and sub-categorizing them (as seen below) was an effective way of presenting an abundance of topics without confusing or putting off the learner.

The sub-categories are also supported by imagery and the status of that topic. The status allows the learner to follow through the course without completing the same section twice.
These characteristics of the E-learning course reflect the guidance that is given by trainers in a face-to-face course.
