Different years students of a pedagogical institute estimated influence of some psychological-pedagogical factors on their attitude to learning. The influence of the factors was estimated by three dimensions: quality (positive - negative), strength (strong - weak), persistence (stable - unstable). The factors were shown to differently influence the attitude depending on the year. The authors interpret their findings, consider the mechanisms underlying particular factors' influence, point to oversighted reserves which can be made use of in order to develop in students persistent and positively-motivated attitude to their principal activity - learning.
