Back in old-school days, we had classrooms with blackboards and chalk, students seated in plastic chairs aligned squarely in rows, and an instructor at the front of the room wrestling lessons plans and poster board-sized visual aids. How the classroom has changed. Now, any business professional with a computer and Internet access can foster his education with online learning. No more transparencies and projectors — today’s classroom uses rich-media technologies, wikis, blogs and podcasting.

Welcome to the world of online learning.
