The highly interactive program is designed to teach the basic physiology of the thyroid hormones and covers:

• location and structure of the thyroid glands,
• synthesis, release, transport and mechanism of action of the thyroid hormones,
• function of the thyroid hormones T3 and T4,
• principal abnormalities of thyroid function - hypothyroidism and hyperthyroidism.

High quality colour graphics are used extensively throughout the program and features such as animation and a Hypertext facility are used to enhance student learning. The program is highly interactive and uses several features to promote this. For example students are required to:

1. Label diagrams by "dragging" labels from a list and "dropping" them into the box corresponding to the correct position on the diagram,

2. Answer a variety of questions included in each section. These may be multiple choice, selecting correct phrases from a list to complete a statement, and true/false questions with feedback.
