“…Changes in behaviour in terms of learning, development and application of their results in practice can be divided into short-term fluctuations with peaks and subsequent declines (cyclic partial changes without fundamentally measurable impacts), in the matter of days (Kanner, et al, 1981), and long-term changes, which are required for the development (Lord, et al, 2010), in the matter of years or more. What is desirable, therefore, is a change observable in the long run, which is experiencing an upward trend or standard-growing or stable level.…”
