A critical analysis of developmental tasks materials in Texas state-adopted language arts and social studies textbooks for grade six in 1963-1964

The problem was to establish and apply a procedure for critically evaluating, both quantitatively and qualitatively, the textual developmental tasks materials in the Texas state-adopted language arts and social studies textbooks for the sixth grade during the school year 1963-1964. Specifically, the study was concerned with: (1) development of criteria for identification of developmental tasks materials, (2) establishment of quality categories for evaluation of the developmental tasks materials identified, (3) validation of the criteria for the identification and quality categories for classification of developmental tasks materials, (4) determination of the quantity of developmental tasks materials contained in each textbook, (5) evaluation of the quality of the developmental tasks materials found, (6) objective presentation of the findings.
