    Development of interest in training by creation emotional and comfortable educational environment by Olga M. Shentsova

    Published 2018-01-01
    “…Pedagogical approach to a solution consists of the following: to present in pedagogical process a possibility of interesting aspects of the educational activity; to excite and constantly maintain the students’ state of active interest by educational processes; to purposefully form and develop interest as the valuable property of the personality in training, promoting her informative activity.Interest in training – “is a form of manifestation of need of the personality for cognitive activity, owing to her emotional appeal and the vital importance, through active aspiration to knowledge acquisition, abilities, possession where in organic unity intellectual, emotional and strong-willed processes interact”.Also the personal and activity training is considered, including the personal focused and individual, informative and synergetic approaches, the levels of development of interest in training are marked out; tools for the emotional and comfortable educational environment, which influences efficiency of development of students’ interest in training at universities. The structural model of the educational environment has been developed, that includes spatial and subject, social, actionable, information and technological, substantial and spiritual components, which are considered by the authors in detail.When determining the educational environment we have used the method of the vector modeling, developed by V.Yasvin, which is based on the system of coordinates, consisting of an axis of FD “freedom-dependence” and an axis of AP “activity-passivity”. …”
