Fernando M. Reimers et al. and student agency in shaping the high school curriculum as ways to personalize learning. One of the pedagogical principles on which this design was grounded was to rely extensively on project~based learning and on active learning method— ologies, such as Design Thinking, that place students at the center of their learning.

As we undertook to design the World Course, we sought both to use a twenty—first-century—skills framework to guide the development of the curriculum and to include in it opportunities to develop specific glob— al competencies. The first implication of this aim is that it is necessary to dedicate time to the curriculum and to recognize that attempting to achieve global competency through curriculum infusion would at best produce only partial and inadequate results. The second implication of lvi
