The aim of the TAAndem-project is to develop a common further education for people from different kinds of professions within the context of "Ambient Assisted Living" (AAL). The further education is addressed to geriatric nurses and craftsmen. The didactic method of tandem learning is applied, so people from various working fields can learn with and from each other. In this paper we will present our concept and the steps of development following the user centred design. Different aspects of the further education that are essential for the upcoming pilot run were tested among potential participants. Methods used were requirement analysis, questionnaire surveys, qualitative expert evaluations and empirical observations. The main result is that the didactic method of tandem learning is suitable for transmitting knowledge to our target group. Several results are given in the following article.
