Students learn by doing at EL Education's network of more than 160 schools. Math, science, and other subjects are taught through "expeditions" that connect them to their communities and teach them the value of service. Students are encouraged to have "academic courage," and they work alone and in groups to conduct original research, analyze data, and present their findings. The work goes in stages as students solicit feedback and make revisions along the way. Each step in the process reinforces a culture of continuous improvement and refinement.
