ABSTRACT
Since before the days of Socrates, teaching has largely involved flesh-and-blood instructors lecturing to their students-beneath a tree, in a colonnaded stoa, or in a brick-and-mortar schoolroom. Today, thanks to widespread access to the Internet, online education is enabling professionals to learn from afar, keeping pace with technological and managerial changes, despite their heavy schedules. Online learning, especially for engineers and executives in technology industries, has emerged as one of the fastest-moving trends in higher education. Thousands of technical and management courses, including degree and certificate programs, are now being offered by universities, for-profit professional development centers, and industry training facilities worldwide.
