To avoid cognitive overload, I have deliberate limited the size of each article. As the student masters each section, they can deepen their knowledge through the links and Further Reading sections. Ideally each page is a self contained document that can be easily digested in one learning episode. They can also act as electronic flashcards for revision purposes. Over time I may decide to divide articles into smaller learning units that reflect the CoreMed philosophy of education. Each fundamental unit of information is will typically re-used multiple times in conjunction with other topics and contexts such that eventually a rich network of interconnecting ideas arise.
