Although the national VET systems differ in many aspects, the development of the new technologies and the spread of interactive and collaborative learning environment have brought about a general intention to launch action researches with innovation objectives. Our four-year project is aimed at the renewal of educational content and methods, and because it is strongly connected to schools, it is of empiric nature. The lecture describes the innovation processes relating to the content-methodological renewal of vocational teacher training. Since 2016, a network of 12 schools has been established in which teachers and students implement content development activities. This work aims to reduce the deficits in vocational learning materials as well as to modernize the slowly changing content. This model, which is aimed at serving this objective, necessarily requires a modern ICT-based infrastructure that helps online and collaborative learning.
