Three of my favorite ones are:

• Kilpatrick, W. H. (1925). Foundations of method: Informal talks on teaching. Macmillan.
• Fisher, G. (1988). Mindsets: The role of culture and perception in international relations. Intercultural Press.
• Meadows, D. H. (1999). Leverage points: Places to intervene in a system. Sustainability Institute.

I also reviewed a broad range of mindset definitions and theories, and published a range of papers that include more references if your interested.
