This study, based on interviews with North American students and Peace Corps trainees in Bogota, and their host families, professors, and other Colombians in contact with the students, attempts to define the non-linguistic barriers to cross-cultural communication between North Americans and Colombians. The purpose of the study is to gather data for instructional materials which could help North Americans close the cultural gap in their dealings with Latin Americans. Results of the study are presented in two parts: (1) a description of the type and amount of data collected and (2) a description of the instructional materials completed thus far. Appendixes include a list of units of instruction which could be developed from the data and the tables of contents for the two units already completed. Finished units are "Initial Immersion in a Foreign Culture," available as FL 001 090 and "Spanish Personal Names," FL 001 089. (DS)
