The Center for Educational Technology (Bildungstechnologisches Zentrum -- BTZ) is a research, development, and implementation (R and D) organization set up by the State of Hesse, West Germany. It has the novel (for Germany) function of being a middleman between politics, research, and educational practice in developing curriculum for German pre-, primary, and secondary schools. The BTZ focuses on six areas: curriculum development and instructional design; learning theory, cybernetics, computer application, and media systems; social and educational psychology and evaluation; science and mathematics; modern languages; and social studies and humanities. The BTZ consists of a governing board, management, an R and D board, and an R and D project groups, each with a specific task. The governing board is composed of both government and BTZ staff personnel. Among the problems which face BTZ are: Uniting educational research, policy, and practice; integrating research development, and implementation within one institution; implementing the center's programs in schools; and finding qualified R and D personnel.
