Between May 1967 and June 1970, the Houston Independent School District in consortium with 14 others contracted with USOE to coordinate the development of an organic curriculum. The project's purpose was to create a climate for change, while interpreting for Houston secondary schools the objectives of a plan that would be: relevant, based on behavioral and related sciences, individualized to student needs, locally planned and directed, economically feasible, and available to all school districts in the nation. Significant gains were made in creating a favorable climate for (1) change in instructional technology, and (2) in staff attitudes toward the development of a learner-responsive instructional system at the project school. Project enthusiasm is evidenced by the fact that the 14 original school districts (now 20) have incorporated, and are assuming a share of the continuation expense. (Author/LLR)
