<< Objectives >>Quality of education is a crucial point to attract and retain students in education. The needs analyses in the partner countries showed that students would prefer more practice-oriented courses and courses that deal with real-life problems. Furthermore, students admitted that they have limited knowledge on the challenges of developing countries. Thus, the IDEC PBL project aims to improve the quality of education by developing a serious game in the field of international development cooperation.<< Implementation >>After reviewing the related literature on serious games and project based learning, the partners create a handbook on serious games. Based on this, we will develop the content of our serious game, focusing on the diverse existence of donors in international development cooperation. After the online serious game has been built up, all partners will test it in pilots, and analyze its effectiveness in improving the knowledge of students.<< Results >>The tangible results are the handbook on serious games and the IDEC serious game. The intangible results and outcomes include that student satisfaction may increase owing to the improved quality of education.We also contribute to the achievement of the 4th goal of the Sustainable Development Goals, especially target SDG4.7.
