Activities of the Southwest Educational Development Laboratory are aimed at meeting the special educational needs of Mexican Americans, Negroes, and Acadian French located within the operating radius of the laboratory. Improved curricular offerings directed specifically toward the regional minorities in Texas and Louisiana have been introduced by the laboratory in science, mathematics, social science, and language arts. Demonstration centers have been established in the 2-state region to speed adaptation of model programs in particular community environments. In addition to curricular improvement, a project aimed at determining the effectiveness of inservice training programs for teachers of the disadvantaged in this region is also underway. (DA)
