About Us

Children follow natural developmental progressions in learning. Curriculum research has revealed sequences of activities that are effective in guiding children through these levels of thinking. These developmental paths are the basis for learning trajectories. 

The Marisco Institute is dedicated to research and social policy in improving learning environments and outcomes for children, birth to age 8.
