When switching to online teaching, the question arises about the feasibility, methods and form of transposing existing teaching materials into the Internet and creating new ones. The aim of the study is to show what opportunities electronic educational environment ViLLE, developed in Finland, has for teaching Russian as a foreign language and as a second home language. The material of the article include exercises created in this e-environment, and the methods of the research include various software and pedagogical solutions aimed at implementing the methodology. During research, starting in 2017, e-learning platform ViLLE has allowed the Russian language to find and to take its place in Finlands digital language teaching system. Different courses were created, with different sets of tasks and exercises that can be used by teachers and students of any educational institution. Some of the courses, among them those aimed at bilinguals, provide an opportunity to familiarize students with the included theoretical material. Having mastered the necessary minimum skills of using ViLLE, any teacher can independently modify tasks and exercises, combine them in the desired sequence and volume, and thus create courses adapted to the needs of their students. An integrated performance analysis system makes their work easier by allowing the teacher to focus on a specific language teaching problem. The results showed that among the existing electronic educational resources, online platforms and e-learning environments are the most essential tools for teaching a foreign/second language, since only they give the teacher the opportunity to independently plan and structure the entire educational process, manage it, use existing materials and create new ones, automatize certain functions, combine various educational events, and communicate with students. The article compares criteria for evaluating such resources and dividing them into two categories: (1) general criteria that include multi-functionality, the set of features provided by the environment, and compatibility with regard to encoding and format of training materials and other system components; (2) those considering needs of specific teachers and students and their resources, namely, resource administrating, creating tasks and courses, managing and monitoring the learning process. The future plans concern carrying out extensive monitoring of the effectiveness of the system in school and university teaching.
