Generally I Was a Technology Lover. I Love Watch Educational Videos online. But most of the times i will be into the conclusion that technology is a much bigger gift but we can't end up with everything online. There is a good point in your question "whether its applicable to chemical/mechanical engineering"? I Would be sure that the replies we would have get later will be "yes" . But I Don't think so. I don't think its practical to conduct a chemistry lab or mechanical lab in internet. Will you be able to know to drive a bicycle or swim through online? There would be a set of people to argue we may still use a simulator for that too. But I Don't think so. The technology may be used wherever direct learning is unavailable. If we are sick or something like that we may end up for taking online classes temporarily that too with a limited content and much practical difficulties.we may use it for a smaller extent. 😀

Well one thing about real class rooms is real time doubt clarifications which helps a great community at the same time

In case of virtual class room this is not possible If this is possible then I am sure it will work wonders in the world of education

No way.It can definitely cant create a better learning experiance compared to black boards in live classroom

Why take engineering? Take just driving itself. There's no point in having a licence if you know well how to drag race in Need For Speed by using your gaming consoles, but you can't drive properly on the real (often guttery) road!

Engineers today are like fake drivers with real licenses. What's the point of getting a license? There are three cases you've to consider here:

1. One who has the license (got it somehow) but doesn't know to drive.

2. One who doesn't have the licence coz they've messed up the tests, but they know to drive.

3. One who has the licence (for namesake) but doesn't want to drive.

Verdict : Practice, trial and error lead to perfection for those who are determined!
