The digitization changes qualification demands of knowledge workers and opens new forms of
collaboration. Solutions are required for enhancing acquisition and transfer of knowledge as
well as training professional skills such as critical thinking communication and
cooperation.Peer Learning (PL) provides potentials for coping with these demands. However it
faces practical challenges as its reusability is low collaboration expertise is required and
lacks leveraging digitization potentials. In contrast the body of Collaboration Engineering
(CE) literature provides insights as it is an approach to designing collaborative work
practices for high-value recurring tasks and deploying those to practitioners to execute for
themselves without collaboration expertise.In this light three research questions shape the
structure of the thesis. First the thesis shows an analysis of the application domain and
develops a teaching-learning approach for creating conditions for PL in large scale lectures.
Second it proposes an approach to designing reference processes for enhancing PL. Third it
presents three studies that illustrate the design instantiation and evaluation of reference
processes for enhancing PL in the field. As methodological approach the thesis uses Design
Science and develops instantiates and evaluates re-usable reference processes for enhancing
PL.
