Some Issues in The Development of a Digital Adaptive Learning Environment

Abstract
The principal reason that distinguishes the developed digital adaptive educational environment is the availability of user experience data from existing open data sources that allow us to create a complete picture of the state of the educational process at various levels. To create an adaptive environment for each student, it is necessary to create personalized courses aimed at developing personal skills that need to be monitored and corrected in the learning process depending on the results of monitoring. Our paper describes some issues of the development of adaptive learning environment including ways for collecting data, applying methods for data processing and generating results on the example of the developed educational web portal. Keywords - Adaptive Learning, Machine Learning, Hybrid Systems, Decision Support Systems, Collection of User Data.
