Instructional software includes applications, drills, tutorials, simulations, games, and problem-solving programs to assist instruction. Computer-based learning uses educational websites and software to enhance the classroom experience. General references provide multimedia encyclopedias and dictionaries. Research tools retrieve information from online sources, and subject-specific CD-ROMs contain instructional materials for a particular topic.
