Thank you so much saifeldin for the documents are very helpful.

Productivity in the Education sector is tied to the idea of targets and levels achieved nationally, and in comparison to previous levels or international markers. Efficency in Education is about achieving those targets with the best possible use of often diminishing resources or at least to avoid burgeoning waste of resources. Look at any of the Government papers in the UK on levels and achievement for more information about one view of productivity in Education.

Sourour, I inserted three links, two classical and a recent paper. I wish help you. Good work.

Productivity can also refer to actively distributing one's digitally creative works online. It's the opposite of being a consumer (and an unquestioning one at that).

If you think you'd find a recent chapter I wrote on the economics of literacy, I'd be happy to send you a pdf. Will need your email address in that case.
