A 3-year Project ABLE social studies curriculum for vocational students was developed by high school teachers around general vocational, citizenship, knowledge, and self-fulfillment objectives and emphasized problem-solving ability, use of new instructional materials, different teaching strategies, and individualized instruction. Structured at three levels of learning, course content at the 10th grade consists of general concepts and treatment of political, social, and cultural problems in diverse societies, while the 11th grade limits the study of concept and treatment to a specific society and the 12th grade to the individual's role in that society. During the first year (1968-69) of implementation, several problems hampered the introduction of the instructional materials which necessitated revisions in subsequent materials. It was also found that in order to objectively evaluate the materials, special criterion measures or appraisal techniques were needed. Other recommendations were that materials should be evaluated against stated learning objectives, student population should be altered to a size permitting validation of the materials, and the format of the units should be changed to provide more variety of instructional media. Several project materials are appended. (SB)
