California Polytechnic State University and the community of San Pablo,Tacana, Guatemala are collaborating in multidisciplinary classes culminating with a two-month Appropriate Technology summer school in San Pablo, “Guateca”, for 20 Cal Poly students and 20 San Pablo college students. Guateca aims to improve the quality of life for both Guatemalans and North Americans by developing local sustainable businesses to strengthen the local and regional economy. At Cal Poly we have interdisciplinary service learning, team-oriented, project-based classes similar to MIT’s “D-Lab”. Cal Poly D-Lab offers students cultural and historical appreciation of international development, year round direct interaction with San Pablo leaders and students, a 12-day Winter Research Trip in December, hands-on appropriate technology prototyping, and sustainable business development with a tangible opportunity to test these businesses in San Pablo. Guateca’s intended output is a group of young entrepreneurs in San Pablo, a valuable exchange student experience at Cal Poly for two San Pablo villagers each year, and for all students: enhanced intercultural awareness, technical competence, and innovative skills. We have a long-term relationship with San Pablo, a community with a history of grass-roots organization prioritizing education, technology and innovation. In summer 2010, we began codeveloping the Guateca program with San Pablo community leaders with the following objectives: (1) to develop an experiential education program (2) to co-design, improve, and prototype technologies, and (3) to create student-lead businesses in San Pablo. In the 2010-2011 academic year, groups of students at Cal Poly and San Pablo have begun co-developing the jointly proposed projects. We seek funding for transportation expenses, teaching tools, construction materials, seed capital, and to support workshops from local entrepreneurs.
