An example that readily comes to mind are the courses on manufacturing processes offered by both MITx and NPTEL. The MITx course was clearly a class apart - you actually got to see the processes in question and how they were applied in the real world factories. When speaking about how a product was made, the lecturer actually bothered to bring samples of those products, sometimes dismantled them, and showed us how they could have been put together. I only audited this a few months ago, and to this day I remember the concepts vividly.
On the other hand, in the videos I watched, the NPTEL course lecturer simply read out from powerpoint slides, which he prepared from a standard textbook. You were better off reading the textbook directly than watching the video alternating between the slides and the lecturer's face. It was a very uninspiring, depressing experience.
