In the article linked below, the author, NOLIWE M. ROOKS, warns that online learning may leave a number of students behind.
The author cites that online students may not get as rich an educational experience as a face-to-face experience. This can be overcome by the consistent improvement and refinement of online course offerings and the methodologies used to deliver the information, i.e. reading, listening to audio file, watching videos, rich discussion posts, and live streaming faculty and student interaction.
Another concern the author has is the preparation of students for online education. The responsibility of placing the correct students in online courses should rest on the student and her/his academic advisor. Students should be assessed for the technological capabilities and their temperament for online learning before being recommended for online learning.
