The importance of different types of review of physics materials in electronic exercise book

A close cooperation between editor (publisher), authors and reviewers is very important for preparation of electronic learning materials (e-learning materials) with high quality. E-learning materials require content review and evaluation of didactic suitability. They also need technical review which is less important in printed learning materials. Multiple possibilities of e-learning materials make the process of development technically more complex. Experiences in planning the high-quality electronic exercise book, for example in the field of physics, have revealed that parallel review is far more efficient than end revision, when the authors' work is over. High-quality e-learning materials significantly increase the success of natural science students'
