For decades, the older leadership theories (. traits , behavioral/styles , situational and functional ) did not explicitly support or address the philosophy of servant leadership. However, this changed with the emergence of integrated psychological leadership theory – as represented by James Scouller’s three levels of leadership model (2011). Scouller’s model – which attempts to integrate the older theories while addressing their limitations by focusing on the leader’s psychology – emphasizes the idea that leaders should care as much about their followers’ needs as their own and view leadership as an act of service.  Thus, the link between the philosophy of servant leadership and modern leadership theory has strengthened in the 21st century.
The goal of the curriculum would be to enable students from around the world to work together to address the water crisis in a concrete way. Students might help bore a freshwater well, propose a low-cost way of preventing groundwater pollution, or develop a local water treatment technique. Students and teachers would collaborate by talking with one another through Skype and posting research findings using collaborative filtering. Students would create simulations and games and use multitouch displays to demonstrate step-by-step how their projects would proceed. A student-created Web site would include a blog; a virtual reference room; a teachers' corner; a virtual living room where learners communicate with one another in all languages through natural language processing; and 3-D images of wells being bored in Africa, Mexico, and Texas.
