Blended learning (B-learning or combined learning, BL) is widely used in universities. Its rational organization makes it possible to optimally combine the elements of classical academic education and elearning resources (ELR). As the world, national and regional experience shows, many instructors during the pandemic were not ready to conduct this kind of learning. A significant part of the instructors experienced difficulties and could not organize the educational process in the BL mode in a quality manner. The low level of design skills in the use of information and communication technologies (ICT) did not allow some instructors to create the curriculum of disciplines holistically. Typically, lectures, seminars, practical and laboratory classes are conducted during the academic study process in full-time format. In turn, modern e-learning involves the use of electronic learning environments (ELE), which are aimed at the development and delivery of educational content, collaboration of all participants in the educational process, collection and analysis of control results. We demonstrate theoretical and practical experience of training instructors to organize BL on the basis of ICT tools at Novosibirsk State Technical University. The authors have developed and implemented a technology aimed at improving the design skills of instructors. The work is valuable in terms of fundamental and practical research in the field of educational design.
