One approach to answering this question is for individuals to visualize their aspirations for what learners are to become and then collaborate in realizing a common vision.
Another approach is to work toward a common understanding of what you know now about your students, what you need to know now to move forward in planning. How can questions about who our student population is now and what it will be in the future shape our planning?
