The primary objective of this study was to survey the Colorado social studies curriculum at the secondary level for its inclusion of international education content. A questionnaire including a list of 31 topics was designed to determine which topics would be covered, the relative scope of coverage, frequency of treatment, and time allotted to various international topics. In the spring of 1970, the questionnaire was mailed to 1276 social studies teachers, 25% of whom returned the questionnaire. Respondents indicated the courses in which they taught each topic the most and least, and how much time was devoted to each. Data indicated that 80% of the respondents covered eight topics in at least one of the courses they taught. The frequently taught topics were more traditional, of a general nature, somewhat ethnocentric and well established in the social studies curriculum. Only half of the teachers said they covered the least frequently discussed topics which were more theoretical and newer topics. History courses were most frequently mentioned as those in which international material was presented. Limitations of the study are the applicability of the findings at the state level to the national level and stated weaknesses of the mail survey. Recommendations emphasize the need to recognize the significance of history courses as transmitters of international education information; to internationalize the history courses; and to focus on and to teach in depth topics less frequently taught.
