This publication describes features of the South Central Kansas Elementary Math-Science (SOCKEMS) project developed as a child-centered program, although the actual teaching materials and methods are not described. Materials are presented in such a way that children learn science by using their perceptual ability to great extent. Considerable emphasis is placed on concrete, tangible, observable investigative activities. Inservice teacher workshops to orient teachers with the methods and materials are provided. Evaluation of the program showed considerable student success related to short term and long term achievement and attitudinal changes. This work was prepared under an ESEA Title III contract. (PS)
