The Child-to-Child (CtC) project involved school-age African children in monitoring younger children's weight and health (since much of the daily infant care in Africa is performed by preadolescents). CtC emphasizes local autonomy and is based on respect for children as morally responsible community members with a basic right to health and education. A case study examined activities of primary school teachers who applied CtC concepts in the Mpika district of Zambia. Third and sixth graders learned about basic health care and the use of growth charts to monitor health during mathematics class. After discussing diarrheal diseases and oral rehydration therapy, the paper describes an investigation of teaching-learning processes in schools using CtC. The study observed students in seven schools as they learned about and worked with growth charts. Interviews and written records indicated the children had a good understanding of the subject. Using a behavioral assessment instrument, students' ability to act appropriately in emergencies (bleeding or severe diarrhea) were examined. Interviews with parents investigated what they knew about CtC and how they felt about home-school relationships. Results revealed that most were strong supporters of home-school links and considered nurturance a very important theme inherent in CtC. CtC activities helped empower low-income, rural African children to participate meaningfully in the health care of younger children. (Contains 53 references.) (SM)
