Modelling in evaluating a working life project in higher education

► We present a method of developmental evaluation based on activity theory in a working life R&D project. ► We examine how the project co-operation is integrated in the planning, implementing and transforming of the joint practices in vocational higher education. ► Modelling works as an investigative instrument of R&D project collaboration but also as a method for bringing concrete improvements in the R&D project. This article describes an evaluation method based on collaboration between the higher education, a care home and university, in a R&D project. The aim of the project was to elaborate modelling as a tool of developmental evaluation for innovation and competence in project cooperation. The approach was based on activity theory. Modelling enabled a development of the curriculum and encouraged stakeholders to participate in the evaluation process. The results verified the features of the method: (1) the contradictions of the joint practice are a central source of evaluation; (2) comprehensive data collection methods are needed; (3) shared tools can be developed in interactive forums in ongoing evaluation, and (4) modelling makes professional expertise visible and brakes boundaries between different professions.
