Generativeness accounts for the open-ended character of learning materials which facilitate cognitive development and the transfer of what has been learnt in one context to more general tasks and/or other contexts.
Transferability: Do the materials encourage the transferability from controlled through guided to free activities and the transferability of strategies, skills and contents to different contexts in and outside the learning environment?
Integration: Do the materials build onto previous knowledge (progression) and help learners to relate concepts?
Cognitive development: Do the materials provide opportunity for learning to learn (problem solving, strategy training, etc.) and promote the awareness of these aspects in the learners?
