This issue of Kaleidoscope, a magazine devoted to the exchange of ideas among schools and teachers in Massachusetts, describes 50 arts and humanities K-12 projects. These projects illustrate the premise that if the arts and humanities are to have their needed impact on a child's growth and development, they must not be treated as superimposed programs, cultural enrichment, or peripheral subjects but must be interwoven with existing curriculum structure. Centering on one or more of the arts, the programs interrelate all of the arts as a body of knowledge, or integrate the arts, into various subject areas. Some are worked out within the normal school budget while others have special funding. All aim at the simultaneous strengthening and expansion of the affective and cognitive areas of learning. "Creating Imaginary Worlds" proposes that eighth graders use their imaginations as they construct, read about, and write about "other worlds." In "Tribal Rhythms" a cooperative artist's group works with teachers and school children in recreating the basis of a ritual society through music and mime. To facilitate communication about these programs, Kaleidoscope includes addresses of contact teachers and write-in forms for new projects. The projects are indexed by city, grade, and subject. (JH)
