When a user accesses a topic, additional sub-categories will appear. After accessing one of the sub-categories, more menu choices appear.
Users are able to research a topic or go directly to an expert to ask a question.
The program encourages the user to access information available on the menu before asking an expert for information. I found that the twelve main headings cover just about any topic. In fact, there are over 300 web sites and email addresses where a user can find experts to answer questions. The experts are people who have volunteered time to answer questions. In this unit students are taught several problem solving techniques.
