This paper offers a presentation of two original multimedia educational resources with interactive online tasks in the German language developed within the course “Teacher”s and translator”s electronic resource” in cooperation with the students of the Faculty of Foreign Languages and International Communication of Tver State University. The purpose of our projects assumes, in the first place, deliberate formation of a learning environment meeting the needs of a target audience. In the process of working over the projects, the authors took into consideration the principles of instructional design that served as a theoretical basis for the development of educational materials. Instructional design is viewed by the authors of the article as a separate branch of practical pedagogy which primarily focuses on the application of pedagogical knowledge in practice, namely, development of high-quality efficient educational resources with the use of modern information technologies. The distinctive feature of the theory of instructional design is consideration of not so much the cognitive parameters and mental processes characterising the learning process as the efficient methods and learning formats stimulating these cognitive processes. The most important result of our work is the conclusion that the projects developed with regard for the principles of instructional design under the ADDIE model contribute to enhancement of students’ cognitive abilities and increase the amount and quality of information assimilated by them; at the same time, the learning becomes more systemic and practice-oriented from the first stages of project analysis and planning. The novelty of our approach specifically lies in practical treatment of instructional design as a tool for development of learning materials, invigoration of learning activities and tutor support of students.
