The main research subject of this study is a teacher. Our goal is to contribute to changes in teacher training in the direction of developing their motivation and creative potential, so that creative personalities of students could be subsequently developed. We chose the methodological concept of a natural developing experiment, in which we study the dynamics of changes in motivation and creativity of student teachers. In the scope of extensive research concept we used various methods to record scores before and after the experiment, such as IMB, DMV, IPOT, WKOPAY and Torrance Figural Test of Creative Thinking. The results were subjected to a quantitative evaluation by means of conventional statistical methods, such as the significance of differences in arithmetic means and index analysis. These were subjected to a qualitative analysis. As a result, conclusions were drawn from the study of future teachers' motivation and creativity. The results have shown significant arguments in favour of aimed and intensive motivational and creative development programmes. As it follows from our findings, interesting also for theories on educational process, the elimination of fear, anxiety, tension and teaching stress can humanise educational environment and also change motives for improving one's creative performance. The goal of our experiment is to contribute to the improvement of undergraduate teacher training and participate in progressive changes in the educational system.
