The use of data visualization in e-learning system

Extensive using of digital technologies in all areas, including education leads to the creation and acquisition of data in a geometric progression, there is a problem of their interpretation and rapid analysis. In particular, the amount of information for monitoring and using the e-learning system in educational institutions is increasing. It`s helps to speed up the perception of information, their visualization, including visualizations of educational materials and some information about educational activities, presented in numerical and textual formats. To visualize data, it is necessary to go through the processes of obtaining, analyzing, filtering, analyzing, presenting, modifying and interacting data. Using tools and technologies of data visualization, teachers can intuitively present materials to applicants, conduct classroom training, pedagogical intervention, assess their knowledge. Students can make a self-assessment, identify their problems in time, and form a system of knowledge and a system of relationships to facilitate the expression and personalization of knowledge. E-learning managers can adjust the goals, methods and strategies of learning management, and make decisions based on this data. The article analyzes the possible options for using data visualization in the e-learning system Borys Grinchenko Kyiv University. It is analyzed how it is possible to use data visualization at different levels of access as students, teachers and administration (including monitors the effectiveness of e-learning and ensuring various educational processes - the availability of electronic courses according to educational / professional / research programs in university departments, their use and certification, analysis of the activity of applicants and teachers, evaluation, etc.).
