The student is changing at universities and university colleges. Also adult-learners find their way to the universities. Formations for adult-learners have to be more efficient. The biggest cost for formations for adult learners is their absence at the workfloor. Question is how to open knowledge in a traditional university (college), taking into account that the students are no longer an homogeneous group. A solution is found in the Goettingen catalogue of instructional models, where for twenty didactic models the possible integration of e-learning or blended learning is presented. Lecturers are supported to develop blended learning courses. Specific formations for lecturers to handle the new situation with very heterogeneous learners are developed and seems to be necessary.
