Analysis of Online Learning Essay Example | Topics and Well Written Essays - 500 words

Analysis of Online Learning - Essay Example This is how I felt after prior programmes taken on-campus and wanted a change in my way of acquiring knowledge.

Working in remote workstations is the modern trend for this technologically advanced society. I found that I could learn this work approach by learning as an online student. More importantly, I realized that online learning offers profound chances of social interaction through various web 2.0 technologies. Â
