Abstract: When preparing students for professional activity, the development of a methodological model of training in a credit-modular system, its components, is considered. In particular, the purpose, content, forms, methods and techniques of teaching are presented on a systematic basis. Most importantly, the importance of the credit-modular system in education is described in detail. The article presents an improved model of teaching materials in a credit-modular system. This model covers the entire system. A separate feature is that this model also describes the goals and objectives of learning in a credit-modular system. The improved model of preparing students for professional activity takes into account the factors of the professional-pedagogical approach.
