To promote participatory learning among the indigenous Tzotzil children of Chiapas, one of Mexico's poorest communities, Tecno.Tzotzil will produce culturally-sensitive teaching aids that advance problem-based and project-oriented learning in which students both produce and share relevant materials and learning outcomes. The Mexican government has created the Consejo Nacional de Fomento Educativeo (CONAFE), a special commission to address educationally disadvantaged communities. Leveraging low-cost laptops to work with two rural schools in Chiapas, Tecno.Tzotzil will create materials and exercises for use with CONAFE's math and science curriculum.
