SUMMARY
The article describes the results of quantitative analysis of open educational resources in the field of information technologies. The study is based on the analysis of the content of ten platforms which provide access to open resources. To achieve the goal, the following methods were used: theoretical (analysis and generalization of Internet sources to determine the popularity of educational platforms and resources on them); quantitative data analysis to determine the relative share of IT-courses on different parameters (the relative share of IT-courses in general and on each platform, in particular, the language of teaching, quantitative content in the thematic areas). Quantitative analysis includes the following platforms that provide access to open educational resources: Coursera, Edx, Udemy, MIT OpenCourse Ware, OpenLearn, Intuit, Prometheus, UoPeople, Open Learning Initiative, Open University of Maidan (OUM). The platforms and their content are briefly described in article. We identified ten generalized thematic areas by analyzing the titles and annotations of the courses presented on the platforms for the IT-sector: programming and software development; algorithms and data structures; computer security and networks; computer graphics, design and visualization of data; Web design and Internet technologies; DBMS and SQL; artificial intelligence and robotics; blockade and cryptography; Operating Systems. The popularity of courses on programming and software development and courses on computer graphics, design and data visualization is proved. We briefly described Ukrainian platforms Prometheus and OUM and made the conclusion about the prospects of their development. Platforms Coursera, EdX, MIT OpenCourse Ware, OpenLean and Intuit are the most complete among other well-known educational platforms. The leader is the platform Udemy: the total number of courses 82 943 and the number of IT-courses – 35 727. We provide suggestions for improving the professional training of IT professionals: organization of independent work, passing of EOR as courses of advanced training, distribution of author's techniques in developing their own courses and promoting them on open platforms.
