This study, funded under an ESEA Title III grant, evaluates the current practices and problems of interdisciplinary arts and humanities programs in the elementary school. Involved in the study were all Title III Arts and Humanities and PACE programs, selected educators influential in the development of interdisciplinary studies, and selected elementary school programs not funded under Title III. Information was obtained from literature of the programs, observations of the projects, interviews, personal correspondence, and questionnaires. The role that higher education played in innovative interdisciplinary programs was particularly noted. Other major problems on which information was obtained were those involving personnel; school-community relations; financing; curricular planning, content, and operations; availability and use of facilities, materials, and human resources; and teacher education. On the basis of the data collected, guidelines were suggested for planning and maintaining an interdisciplinary program. (An extensive bibliography and appendices analyzing over 140 interdisciplinary programs are included.) (JB)
