Summary

The challenge of the use of digital learning materials is to determine which of these materials actually contribute to the quality of the education provided. Reints and Wilkens give a detailed and sophisticated overview of criteria for digital materials evaluation and – what is even important – of the underlying instructional principles. It has been used as material for discussion within the training programme for the teaching staff of UNESCO-IHE.The criteria are organized into three groups: 1. Content, focused on selecting, organizing and packaging the content; 2. Pedagogy, focused on instructional strategies, learning activities and regulating learning processes; 3. Presentation, focused on text comprehension, visuals functions and lay-out.
