In the educational process, the effects of the communication function on the change of meaning of the ideas expressed in teaching are important in today's teaching and learning. Considering that sometimes misunderstandings arise between the parties involved in the learning process (teacher and student, teacher and learner). The article is about the phenomenon of the “language game”, which is one of the topical paradigms of recent times. The famous philosopher L.Wittgenstein was the author of this term, which is included in the science of linguistics. Of course, similar terms can be found in the works of other famous philosophers, linguists, psychologists. But with the appearance of the term “language game”, L.Wittgenstein seems to have restored the bridge between language and philosophy, which existed for a long time, but which remained due to some problems since centuries. Since pragmatics, which is one of the aspects of the sign system, examines the points related to the activity of the language, the “language game” is also considered one of the main points in the center of its research. Although “language games” by their general appearance and even their origin resemble the structural form of ordinary speech acts, they are completely distinguished from them in terms of a number of features. The main characteristic of “language games” is the disruption they cause in linguistic norms. Deliberately, purposefully violated rules have a special effect on the semantic load of each expression in the encoding-decoding process. As a result, the illocutionary force of the locative act formed in the form of a “language game” differs from the illocutionary force of ordinary speech acts. An element of illocutionary force that is normally present acquires a dual character. The illocutionary act, which has a double power, makes the communication process very interesting on the one hand, and complicated on the other hand, compared to ordinary speech acts. In this article, we will try to extensively investigate the effects of the communication function in the educational process on the change of meaning of the ideas expressed in the teaching, based on the educational materials.
