What is online education?
Online education
• Education through Internet• Anywhere, any time, any device connected to
internet• Asynchronous learning
• Fixed # of weeks• All the work is graded & final grade is assigned• Student evaluation of faculty• Degree certificate
Why did it become popular?
Snippets from history
• American higher educational system: Public, private non-profit, and private for-profit universities (companies), Regional accreditation agencies, state agencies
• Question: What is #1 priority for private for-profit university? Quality or Money?
• First online course ~20 years ago, likely by for-profit university
• First online degree program?• MBA. Why?
Snippets from history …
• How reliable is online degree? Does it help to get a job?
• Online colleges got accreditation• Turning point (my opinion): Traditional
colleges started online degree programs• Misleading ads: “Point…Click…Degree…”• Reality: online courses require more work.
Who is a typical online student?
• Working adults who have difficulty attending a traditional college
• Hard-working employee who wants to get promoted, but does not have a degree
• Military personnel• Moms with young children at home• Students from rural areas
Online education is NOT for every one!
Who is typical online faculty?
• has full-time job in the industry• works as adjunct faculty• Why?– Additional income– Passion– More interesting than regular job!
• Lot of retired people too. Why?– Flexible, travel & teaching can mix
How is it done?
Typical online course• accessible only to students enrolled in that course
within university OLS (Online Learning System).• has an assignment due every week or every 2
weeks once• Participation in Weekly discussion questions (DQs)
is mandatory.• Courses run for only 5-8 weeks. • Has 10 to 15 students• Has students from multiple time-zones, sometimes
from other countries too.
Grading scale for typical on-ground course
• Class Participation: up to 5%• Quizzes/Attendance: 10%• Assignments/Projects: 40%• Exams: 50%
Typical Grading Scale
• DQs/participation: 25%• Quizzes: 10%• Assignments: 30%• Exams/Projects: 25%• Team assignments: 10%
Compare with on-ground course
• Student-centered vs. Faculty-centered• Lectures optional• Students need to be self-motivated• Forced to participate• Did the student actually do the coursework?
Typical online student
does the following every week:• logs into the course at least once in 2 days• reads the book’s chapter(s) for the first 3 days• makes 4 to 8 posts distributed over the next 4
days• submits other assignments towards the end of
the week.
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)
• Goal: Come up with most reasonable answers through discussion
• 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.
• Goal: 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…
Team assignments
• Can it work online?• Can it be better than on-ground?• Potential for higher level of contribution from
each student• More details in separate presentation.
Compare with
• Self-paced learning• Correspondence education
Advantages?
• No commute to college• No need for classrooms• No conflict in course/work schedules• Multimedia lectures can be reused• Learning/teaching can happen any where, any
time
Disadvantages?
• Online learning not for every one• Online learning not suitable for all courses– Complex labs hard to do online
Technical Architecture

Internet
OLS serverSecurity gateway
Online University
Online Learning System (OLS)
• Lots of software applications out there.• Popular ones: Blackboard, Sakai, Moodle, …• In addition to courses, OLS provides network
space accessible to faculty, courses, …• Tons of functionality to run the course
efficiently
Future?
Future of Online education?
• High quality online lecture videos– students can view them at any time
• More acceptance at workplaces• Learning experience comparable to traditional
classroom• Unlikely to replace traditional education though
Still not for every one!
Potential in India?
Higher education in India
• Attended T4E conference in IIT Chennai, July 14-16 and met several educators.
• Lot of concerns about quality of higher education, but not many answers
• Online course materials:– MIT Open courseware http://ocw.mit.edu– NPTEL National Programme for Technology
Enhanced Learning http://nptel.iitm.ac.in/
CS & Engineering education:USA vs. India

college rank college rank
Can online education work in India?
• Issues & needs are similar to America• Indra Gandhi Open University runs distance
courses, not clear how close it comes to online courses run in USA
• Does require reliable broadband connection• With some adjustments & planning, I believe
online education may work well here too.
Can online educational materials augment physical classroom?
• Several 3rd tier colleges in Karnataka using NPTEL course materials (including lectures) since local faculty not ready to teach those courses
• It should work in Tamilnadu too.
