Compare with on-ground course
• Student-centered, NOT faculty-centered• Lectures optional• Students need to be self-motivated• Forced to participate• Did the student actually do the coursework?
![Page 14: Online Education is the future?](https://reader030.fdocuments.in/reader030/viewer/2022032710/568168ad550346895ddf620e/html5/thumbnails/14.jpg)

Typical online faculty
does the following every week:• ensures that weekly material and DQs are setup before
the week starts• grades the previous week’s assignments • comments on DQ responses & offers closing thoughts• responds to “cry for help” posts/emails in timely manner• makes phone calls if needed.• responds to phone calls during office hours• spends 5 to 15 hours every week for each course

Recent focus
• Continuous improvement in action …• Utilize relevant web resources in courses• Develop multimedia lectures to explain tough
concepts• Increase academic rigor – test application of
concepts using weekly quizzes • Improved communication tools

Major issues?
• Plagiarism in popular assignments• Google-generation has limited no patience • Quality of Faculty?• Students’ preparedness• Time-discipline for both students and faculty• Micro-management from university• Low pay to faculty

Weekly DQs (Discussion Questions)
• Set difficulty of DQs at 110%• Focus is on discussions, NOT on perfect initial
answers. Wrong answers are perfect discussion starters!
• Faculty should facilitate & shape the discussion little bit, but should NOT kill it.
• Each post should add value to the course, requirement to count towards participation.

DQ strategies
• Basic: 2 to 3 questions• Expanded: 5 to 10 questions• Personalized: assign specific question for each
student for posting initial response• Empowered: designate each student as “DQ
lead” for one question
• More details in another presentation…
