his study aims to measure the perceptions of social studies teachers in relation to sustainability and their attitudes towards including the priority of the environment and natural resources, as stated by the vision of Oman 2040, in the social studies curricula for grades (5-12). The researcher employed the descriptive approach and the sample included (339) male and female teachers of social studies in the governorates of Muscat, North Al- Batinah, Al-Dakhiliyah, North Sharqiyah, Al-Dhahirah, and Dhofar. The researcher applied two tools to carry out this study: a scale to measure grades (5-12) social studies teachers' perceptions of sustainability and a scale to measure those teachers' attitudes towards including the priority of the environment and natural resources in social studies curricula according to Oman Vision 2040. The scale measuring the perceptions consists of eight factors and 38 items whereas the scale investigating the attitudes includes seven goals regarding prioritizing the environment and natural resources. The arbitrators confirmed the validity of the two tools and the reliability of the tools was verified using Cronbach's alpha as the stability coefficient for the perception test reached (0.81), and for the attitudes was (0.80). The study concludes that the general average of social studies teachers' perceptions of sustainability was high with an arithmetic mean reaching (3.56). Moreover, the results shows that the median for the attitudes towards including the priority of the environment and natural resources of Oman Vision 2040 in the social studies curricula for grades (5-12) ranged between (2-5) and that the most frequent median was related to three objectives regarding prioritizing the environment and natural resources. In relation to the variables of gender and specialization, the results indicates that there were no statistically significant differences at a significance level of (0.05 ≥ α) concerning the perceptions of grades (5-12) social studies teachers towards sustainability in regard to all factors. Furthermore, the value of the Spearman coefficient for the perceptions of social studies teachers for grades (5-12) towards sustainability in general and their attitudes towards including the priority of the environment and natural resources of Oman Vision 2040 in the social studies curricula, the correlation level ranged between (0.07-0.11). In light of the previous results, the researcher recommends developing social studies curricula in line with the goals of the sustainable development and the priority of the environment and natural resources according to Oman’s Vision 2040 through the implementation of workshops in cooperation between the Oman Vision Implementation Office and the Ministry of Education in order to raise the level of knowledge and awareness of the objectives of the vision. The researcher also recommends preparing a training program for social studies teachers that meets the needs of teachers in the field of developing tools and methods of teaching in relation to sustainable development and natural resources.
