This inventory of social studies teaching competencies was developed to serve as a model and guide for social studies instruction in Pennsylvania elementary and secondary schools. It is designed to aid teachers in developing competency-based programs. The inventory is a combination of ideas from six regional workshops attended by teachers, administrators, teacher educators, student teachers, graduate students, and consultants in competency-based teacher education. An introductory statement cautions that the guide should not be used as a basis for evaluation of teachers presently in the field except as a general guide for in-service training. Competency-based teacher education should begin in the institutions which provide specialized courses in education. Forty-seven competencies are listed, grouped according to four categories. The categories are: (1) cognitive domain, content, and overall social studies knowledge; (2) skills, techniques, and methodology; (3) values such as personal commitment, objectivity and intellectual integrity, acceptance of diversity and pluralism in our society; and (4) professional teaching characteristics. All competencies should be considered applicable to all elementary and secondary grade levels. (Author/AV)
