This two week unit has attempted to alleviate two deficiencies normally found in instructional materials: superficial treatment or neglect of developments since World War II; and, the overemphasis on conflict. Topics have been selected for in-depth discussion, and emphasize the Organization of American States, the Alliance for Progress, and the settlement of the El Chamizal Dispute. The goal achieved is better balance between conflict and cooperation in the discussions of United Stated foreign policy specifically, and inter-American relations in general. Content objectives are indicated for each topic. The "Suggested Activities" have attempted to provide opportunities for students to develop critical thinking skills leading to the formulation of generalizations or hypotheses. Teacher-guided discussion of open-ended questions is used. Supplementary activities are suggested for further exploration of the topics. Units are designed to be used independently, and flexibly depending on the classroom situation. A variety of materials are recommended since most of the topics are of a controversial nature. Readings, sources of materials, and transparency masters are provided in the appendix. Related reports are: ED 036 679, SO 000 019, SO 000 020, SO 000 021, SO 000 023. (SBE)
