This bibliography is an annual supplement to the first bibliography on human relations in the classroom (ED 051 315), including documents announced in the 1973 issues of "Research in Education" and journal articles cited in the 1973 issues of "Current Index to Journals in Education," and contains references to published books, documents, journal articles, and unpublished articles in the ERIC system. Citations in the bibliography encompass such concepts and issues as: activism, African American Indians, aspiration, changing attitudes, classroom environment, cross cultural training, cultural differences, curriculum development, ethnic groups, human relations, interpersonal relationships, motivation, music education, Negro attitudes, self-concept, social influences, student attitudes, student teacher relationship, teacher attitudes, teacher education and institutes, and testing. Citations for documents are each followed by an annotation edited to suit the purposes of the bibliography; journal articles listed are followed by subject headings, and in many instances by brief annotations. In this third annual supplement, lengthy document abstracts have been dropped in favor of brief annotations, supplemented by appropriate subject headings. (Author/JM)
