Based on the visit of an international team studying the education and cultural development of migrants, this report describes school re-integration for children of Greek migrants returning to their home country. Part 1 outlines the purpose and itinerary of the three-day visit. Part 2 characterizes Greece as having a long and complex tradition of migration and gives numbers of Greeks emigrating abroad and returning since 1968. Brief descriptions are provided for state programs that deal with employment needs, encourage research on the impact of migration, and sponsor summer camps for Greek children living abroad. Part 3 covers the visit to an experimental project serving 53 children of migrants in nine back-up classes--small groups meeting four to five hours weekly after regular school hours. The goals of the three-year project are described--a study to identify problems encountered by migrant students, development of teaching materials, and in-service training for back-up class teachers. Part 4 provides a general evaluation of the visit and makes recommendations concerned with provision for the linguistic knowledge of emigrants' children, cooperation of back-up class and regular teachers, in-service teacher training strategies, and parent involvement in school activities.
