Dear All,
1) It depends what we want to do Ph.D. for. If I want to pursue basic research leading to a major recognition, I should pursue a direct and full time Ph.D. from a University. Take a JRF exam, and go to TIFR or IISC or other institutes and pursue a full time Ph.D.
2) Many working professionals want to do a Ph.D. in an area they've worked for 10-25 years. For them Ph.D. is more of a passion and it helps them get well grounded in the current literature and body of knowledge of the times and then they come up with some concrete finding or novel model from their own experience and also the research work that they do. For this kind of work, what we need is a good local guide (Expert) under whose guidance Ph.D. can be pursued. The efforts of IGNOU is enabling these kind of bright professionals to pursue their passion and contribute to the body of knowledge and also gain professional benefits which flow from possessing a Ph.D.
3) I've come across many doctorates from different universities and after interacting, I ask myself - "Who awarded them Ph.D.,?".
4) As regards IGNOU, I've seen many professionals do their PG courses in IGNOU and toil to be able to take up exams. IGNOU has built that enviable reputation as a quality and professional Long Distance Education provided and comparable with the very best of the lot.
5) I'm sure Colleges and Universities do recognise a Ph.D. from IGNOU and hence it will accrue benefits to the teaching fraternity accordingly.
My two pence.
