Historical documents and interview data are compiled to develop a chronology of critical events used in studying the impact of the Applications Technology Satellite educational demonstration (ATS-6) in Alaska. This method of evaluation was implemented as a parallel approach to that of gathering data in the villages from Native informants and from project participants directly at a debriefing meeting. The chronology approach has both practical and theoretical advantages, in that it is less intrusive than other methods such as surveys or questionnaires and more practical than true participant observation, which requires a major investment of time and resources in a cross-cultural setting. A comparison of the issues generated by the chronology and by the village involvement approaches is made. Discrepancies are identified as a way of judging the usefulness of the chronology method as a sole or combined approach to evaluating a field-based project within practical constraints. (Author/MV)
