The current study aimed to examine the effectiveness of a training program based on the Theory of Cognitive Balance in enhancing ethnographic research methods among social studies teachers in the Sultanate of Oman, as well as their attitudes towards these methods and their perceptions of the program's effectiveness in developing social studies curricula and their specialized knowledge related to cultural tourism and oral history. The study sample consisted of 30 social studies teachers from Al-Dakhiliyah Governorate, including 15 male and 15 female teachers. To achieve the study's objectives, the researcher adopted a mixed-methods approach with a multi-phase design. Various tools were used to collect data, including quantitative tools such as the Ethnographic Research Methods Test and the Attitude Towards Ethnographic Research Methods Scale, as well as qualitative tools like two interview forms to uncover the trained teachers' perceptions of the training program's effectiveness in developing social studies curricula and their specialized knowledge related to cultural tourism and oral history. After ensuring the validity and reliability of the quantitative tools and the credibility and trustworthiness of the qualitative tools, they were applied to the sample. The study concluded with the following main results: - There were statistically significant differences in favor of the post-application in the Ethnographic Research Methods Test. The study results also indicated no statistically significant differences attributed to gender and years of experience variables. - Statistically significant differences were found in the post-application regarding attitudes towards ethnographic research methods across all scale dimensions except for the fourth dimension. The results also revealed statistically significant differences between males and females, generally favoring females in the second dimension (willingness to work with ethnographic research) and the third dimension (importance of ethnographic research for social studies teachers), as well as in the overall attitude score. The study results indicated no statistically significant differences attributed to the years of experience variable. - The interview results revealed the training program's contribution to developing the social studies curriculum with topics related to cultural tourism through proposing enrichment topics and activities (classroom and non-classroom). The interview results also showed the development of teachers' knowledge of visited heritage sites, which in turn enhanced their specialized knowledge. - The interview results disclosed the training program's contribution to developing the social studies curriculum with topics related to oral history by proposing enrichment topics and activities. Furthermore, the interview results revealed the development of teachers' knowledge of oral history related to visited heritage sites.
