what is the meaning of immediacy?

To me, that means education that is needed immediately.

Immediacy – immediacy in education would in this case mean whatever is to be done in education should be done at first, at once, or without delay. Whatever the problem is requires immediate attention

Immediacy IS THE ACT OF BEING IMMEDIATE; or URGENCY,

Immediate presence of an object of knowledge to the mind, without any distortions, inferences, or interpretations, and without involvement of any intermediate agencies.
