This bulletin briefly describes research activities in the field of curriculum development for comprehensive and upper secondary schools in Finland. The comprehensive schools, established by law in 1963, offer a uniform curriculum to all Finnish students for the first nine years of school. After attending the comprehensive school, students may attend either an upper secondary school leading to university education, or enter a vocational education program. Research has been concerned with the implementation of the new comprehensive schools, and with instructional improvement in comprehensive and secondary schools. The amount of national funding for research contracts from 1965 through 1976 is also discussed. (Author/MV)
