This paper introduces a new collaborative model for design-based research (DBR), model-based design research (MBDR), in which the design process is carried out through model-based reasoning (MBR). The objective of the paper is to discuss how MBDR can be used as a method for educational innovation, which is a social transformation occurring when a certain group adopts a new educational practice. This aim is approached by analysing three MBDR cases and comparing the results to the possibilities and challenges rising from the innovation research literature. According to the analysis, MBDR is a promising method for creating and teaching educational innovations. It is most suitable for inventing and supporting the adoption of new practices. By conducting DBR through MBR, design community can produce a comprehensive need analysis. This way design solutions that meet the design objectives can be constructed. Comprehensive need analysis and goal-oriented design lead to successful projects and designers more comprehensive participation to the research
