Formation of cyclic calculation organization skills in it-lessons

Abstract

Apart from mathematics, informatics has the greatest potential for forming algorithmic thinking in schoolchildren. In many ways, the role of informatics in the development of algorithmic thinking is due to the skills of cyclic calculations that are formed when learning to program. However, despite the considerable experience gained in this field, due to the constant development of IT, programming languages, and programming environments and, accordingly, the frequent updating of computer science curricula, we have to state the lack of effective methods of developing skills for the organization of cyclic calculations and sufficient didactic material. In the article, based on the content analysis of the materials on the Internet, the most popular programming languages studied in school were identified, as well as the state of development of the problem of forming skills for the organization of cyclic calculations in high school computer science classes was clarified. Based on the analysis of computer science curricula and current high school computer science textbooks for the purpose of forming skills in the organization of cyclic calculations in high school computer science lessons, methodological problems were identified, which are proposed to be solved using the author's didactic materials. It was established that high school students have a low level of interest in learning programming and a lack of motivation. The study of teachers’ opinions regarding the situation with reluctance to study programming, in particular, cyclic calculations, revealed that among the main reasons are a small number of hours for studying cycles, the lack of sufficient material and technical base, traditional (lecture-practical) teaching methods, the lack of a sufficient number of tasks for mastering cyclic calculations. Further research is needed: on the issue of methodological support for the formation of skills in the organization of cyclic calculations in high school informatics classes in the conditions of distance education, as well as in the extracurricular format of education.
