You can, for many of the online courses, work through the course 24 hours a day, morning, noon or night. Chat rooms and e-mail and bulletin boards can provide feedback and interaction. CBT courses normally do not have this form of interaction, but do have other feedback mechanisms within the course. Comments from the instructor may take longer to get as they would be via e-mail, phone calls, or the U.S. mail. Online courses may require more time than a traditional on-campus course if the student is unfamiliar with the necessary technology.
Online courses use advanced technology for teaching and communications.
Online materials, supplemented by print materials, are the primary source of directions and information in online courses.
