The importance of learning improvement is more and more recognized. Process capability maturity modeling elaborated by the Software Engineering community became applicable for any process-oriented activity assessment and improvement. This paper contributes to the solution of learning improvement problem based on the process quality attributes modeling approach. The consciousness as a learning process quality characteristic is introduced. Two-dimensional Learning process model based on R. Marzano taxonomy of learning objectives and on the staged Learning process maturity model has been developed and validated. (C) 2017 The Authors. Published by Elsevier B.V.
