Massive development of online learning materials

We participated in collaborative development of more than six hundred comprehensive online teaching materials for higher professional schools in the Czech Republic. The paper focuses on explaining the procedures and methods that we used to make the development process as efficient as possible, which was necessary with respect to the quantity of the materials and the limited time. Managing the logistics was the key, as several hundred people took part in the project. We are also describing, from the edagogical point of view, the OER structure, its division into educational blocks, and types of educational objects.
