Too often teachers and students doubt their own abilities to forge collective work and dynamic critical learning in the midst of education reform practices that limit their opportunities to do so. This doubt can be heightened for elementary school teachers or even their students who are led to believe that they are not capable of engaging critically with their education and their world. The Problem-Solution Project erases this doubt through merging service-learning, critical pedagogy, and constructivism. This approach to teaching and learning is designed to empower teachers and students while they meet curriculum standards and actively contribute to the transformation of their world.
