Rajendra Sir,
I am from the faculty of education, but I found nothing complicated about it. Even this is the first time such doubt is raised. I have gone through many MOOCs from various platforms. But I think this MOOC is the best MOOC in my learning life. Jargons that you are talking about viz. LeD, LbD, LxT, LxI are dealt in detail in every week. So let us have patience and keep learning step by step. If we have any doubts about any concept which you call as jargons, we have ample opportunities to raise our doubts through discussion forum (LxIs). There is live interaction each week where experts can clarify your doubts.
The topic of this MOOC is about designing and developing MOOCs. So there ought to be new terminologies to come. We need to learn them one by one and use LxTs (additional resources) as well.
One more thing I would like to suggest is that we should come to the conclusion at the end of the entire MOOC. It is too early to judge it. I am sure Sit that you will be immensely satisfied.
