Interactive learning aided by JavaScript

In recent years, the use of information technology to support learning in nutrition education has moved from mainframe-based programs to PC and Internet-based systems. Many lecturers are now exploring the use of the Internet and Intranets for education and this adds a new potential method for providing support to students.
