Abstract: The disclosed systems and methods for computer aided instruction and electronic publishing employ modular design approaches whereby instructional and informational content is broken into multi-level objects including self-contained electronic learning and electronic content objects. The system and method facilitates the development, maintenance and modification of course and publication content because they may be advantageously located centrally in a large library of independent electronic learning and electronic content objects that serve as building blocks for electronic courses and publications. Modular CAI systems and methods of the invention can be used to monitor student progress both by administering examinations and tracking what content particular students have accessed and/or reviewed.
