The study utilized action research to examine how the incorporation of non-curriculum service learning elements, including group design, health care introduction and program design and assessment, into the course content for social studies students affected their attitude toward "aging knowledge", "aging attitude" and "intention to serve the older adults". Learning outcomes include curriculum redesign such that the students learn how to serve the older adults and interact with them from a young age. Approximately 229 tertiary institutions in elderly care institutions participated in the study. The research method involved recording observations of how the students served the older adults and interacted with them. The observations were supplemented by focus group meetings in which participants discussed how including service learning elements into the curriculum changed the students’ knowledge of aging, their attitude toward aging, and their intention to serve the older adults. Findings of the study were: (1) participation in the curriculum increased students’ aging knowledge, attitude and service intentions; (2) participation in the curriculum increased students’ intentions to choose older adults service as their career; (3) students have more frequent interaction with their aging attitude and service had higher level of intentions to choose older adults service as their career.
