For engineering, fundamentals hardly change. The theory of fluid, thermal, electromagnetics are the same since decades ago. Even the theory of communication engineering including signal processing doesn't change much.

local course explained a theorem in 30 minutes.
no explanation on application of theorem.

stanford explained and derived a theorem in 2 hours.
stanford showed applications of the theorem.

why the difference ?
because stanford professor was an expert in that area.
local lecturer was not an expert in that area, he was assigned to teach the subject
