This article is devoted to the analysis of methods of teaching computer science of natural and mathematical direction on the updated content, the solution of actual problems, methods and techniques aimed at the formation of students ' skills. The essence of the updated educational program is the formation of functional literacy of the child. One of the current problems is the formation of professional competence of students in grades 10-11, the formation and provision of the necessary resources for conscious improvement of the course of professional activity in practice. Today in the school learning of science and mathematics in profile classes accompanied by a number of difficulties, due to the breach of the educational-cognitive characteristics of students of different profiles, orientation of training programs to increase scientific information. In accordance with this, it is very important to conduct a comparative analysis and create a scientific and theoretical basis for the unification of computer science education. As a result, we believe that the student should use this knowledge in life. The results of teaching and learning can only be achieved if the topics studied in computer science are understandable, clear and specific to the student.
