The Chinese term 'Héxié' (和谐) means something like 'harmonious' or 'balanced'. In this article the model presented draws on Xi's 'Noteworthy Conduct and Independent Character: The Way of Hexie Education', which unfortunately doesn't appear on the English internet. Héxié also reminds readers of the concept of the 'harmonious society' (和谐社会), the centerpiece of President (2003-2013) Hu Jintao's political philosophy, and is also the name of China's high-speed train network. The HeXie Ecology Model itself considers Bronfenbrenner’s 'five levels': the microsystem, the mesosystem, the exosystem, the macrosystem, and the chronosystem. In this ecology the authors combine Héxié with a problem-based learning (PBL) framework outlined by Kek and Huijser. The challenge (interestingly posed as a challenge for institutions) is to find that balance between the changes brought about by self-directed learning and institutional resilience, or put differently (following Xi), between action and planning. This paper rewards effort, but it also demands it.
