Since the advent of the No Child Left Behind Act of 2001, classrooms in the U.S. have experienced a steady decline in the amount of time teachers spend on social studies, with the elementary grades suffering the highest level of decline. There is currently a need to understand how teachers perceive the problem of insufficient social studies instruction time and gain their perceptions of curriculum integration as a solution. The purpose of the qualitative case study was to explore how 14 elementary social studies teachers in Grades 3 to 5 integrate social studies throughout the curriculum. In addition, another aim was to evaluate the outcomes of employing an integrated social studies curriculum on teaching civic competence to students. This qualitative case study included interviews and focus group discussions; data were then analyzed using a thematic analysis. It was discovered that teachers believed that by increasing instructional time for social studies, students’ understanding of the subject and its concepts should also increase; however, the key disadvantage was the need to have adequate time and planning to integrate the subject. The interviewed teachers shared that the best method of integration is by incorporating social studies concepts in classroom projects and activities. From the results, it is then recommended for the integrated curriculum theory to be strongly considered by the key educational decisions makers in the country. The results can help the schools determine how to best increase social studies instructional time, improve quality of social studies education, and the positive effects of instilling civic competence among their students.
