The aim of our research is: to show the meaning of proverbs as the notion of authenticity of materials, which may include: the establishment of phenomena and properties; their evaluation; a prescription, a rule, etc. By the help of this material the purpose of our research is to provide the developing of the teacher’s creativity by using authentic material at the lessons. The following theoretical methods of the research were used to solve the tasks formulated in the article: a categorical method, structural and functional methods, the methods of the analysis, systematization, modeling, generalization. The results of the research. We think that for the developing of the teacher’s creativity by using authentic material at the lessons the main approach has to be the procedural one. This approach defines creative activity as a purely internal process based on human ideas, and as a result of the existence of such ideas should stimulate creative activity, should be in its «external form», through which it will be able to be perceived by other people. Conclusions. In such a way we singled out the levels of creative activity and proposed to consider this activity according to two main positions: as a process that takes place at a certain point in time, and as a process in its broad social and historical contexts. We also have to underline the main characteristics of the creative process: creativity is characterized as an idiosyncratic, unpredictable process. It is characterized by inconsistency and randomness. In the creative process we can identify the following main stages: 1. The preparation for creative process. This stage is directly related to a desire of the subject of creative activity to change the existing social situation, which for some reason has ceased to satisfy the person. 2. Frustration in the process of providing the creative activity. The transition to this stage occurs at a time when, after analyzing all the information, as well as working out all the options for solving the problem, the subject of creativity, however, does not find the means and ways to solve the task. 3. Incubation in a creative activity. The incubation stage involves the unconscious solution of the problem by a person, during which the left hemisphere of the brain is activated. 4. The insight in the creative activity. The insight is a short, but quite emotional stage of the creative process, the moment of entering the sphere of consciousness of the decision to solve the problem. This stage is characterized by violent positive emotions, recovery, and sometimes even euphoria. 5. Finding a solution. Finding a solution as a result of verification of hypotheses is a final stage of the creative process, during which the truth is verified using logical means, and the intrigue of this stage is a great possibility of erroneous verification of formulated hypotheses.
