Abstract
The central question in this article is how teachers socialize pupils. Our hypothesis is that socialization takes place when an individual identifies something as a problem or as undesirable. In the process of socialization, teachers sometimes make mistakes. Attempting to hide these mistakes, however, may result in new or even greater mistakes. D. Kahneman implies that people do not like loss or failure. People attempt to justify earlier incorrect decisions by often undergoing senseless stress and exertion. People agree to exert themselves to guarantee what in their opinion is a fair and equitable solution to a particular situation. Subjective probabilities play an important role in our lives. This paper presents the results of an ethnographical study of education. Our findings suggest that mistakes and negativity contribute to strengthening norms be cause "bad is more representative than good". In addition to negativity, teachers try to teach norms through collegial responsibility and conscience, and regulation is important at every step. This study concludes that both success and failure are constantly renewed in a cycle. That is why people tend to use earlier behaviour models, including self-evaluation and beliefs, which are continually actualized. The importance of a supportive, positive, and optimistic learning environment cannot be underestimated. The concept of psychologically sustainable education requires greater in-depth study.
