This teacher's guide to the sixth grade social studies course on United States history, which is part of an articulated sequential curriculum for grades k-12, contains resource units which emphasize culture concepts in studying the American Indians and the Spanish, French, and British settlements. Cognitive and affective developmental skills are stressed. The seven units are designed to help students learn scholarly values, democratic values, and the value of human dignity. Inquiry strategies encourage pupils to learn through the discovery process and to set up hypotheses by recalling concepts and generalizations learned by experiences and previous classes. Four major sections are included in the guide. The first section presents information on course objectives, rationale, descriptions, teaching strategies, how to adapt resource units to specific classes, and how the course fits into the total program. The second section consists of charts indicating the way in which cognitive, affective, conceptual, and generalization skills are developed in different units. A background paper, written by Robert F. Berkhofer Jr. and contained in the third section, identifies the important topics to be taught in each unit. The last section provides a content bibliography. The seven units are contained in documents SO 003 147 through SO 003 153. (SJM)
