So imagine that a group of teachers and middle school students decides to tackle the question, What is justice? Young adolescents' discovery of injustice in the world is a crucial moment in their development. If adults offer only self-serving answers to this question, students can become cynical or despairing. But if adults treat the problem of injustice truthfully and openly, hope can emerge and grow strong over time.
As part of their discussion, let's say that the teachers and students have cocreated a middle school earth science curriculum titled Water for the World. This curriculum would be a blend of classroom, community, and online activities. Several nongovernmental organizations—such as Waterkeeper, the Earth Institute at Columbia University, and Water for People—might support the curriculum, which would meet national and state standards and include lessons, activities, games, quizzes, student-created portfolios, and learning benchmarks.
