These workers must troubleshoot and repair increasingly complex equipment. Many have no formal electronics training, and distance and work schedules are barriers for skills upgrading. Although traditionally taught using lectures and texts, the best way to simulate the concepts of computerized planning is using computer-based learning, making it ideal for ALNs. Communication takes place via the internet. Developers enhanced their courseware with software packages that simulate electronics laboratories and integrate problem-solving and critical thinking exercises related to electronic circuits.
Students communicate with each other and the instructor using e-mail.
