We propose the use of an averaging scheme, which recovers gradients from piecewise linear finite element approximations on the (1 + ฮฑ)-regular triangular elements to gradients of the weak solution of a secondorder elliptic boundary value problem in the 2-dimensional space. The recovered gradients, f
