This paper reports on a field study which was undertaken in an aboriginal elementary school to understand aboriginal students' learning experiences and their interactions with the social cultural context. This study took place in a Elementary School in Shiow-Lin County, Hualien (About 80% of the teachers are aboriginal people; more than 99% of the students are Atayal). This study utilized observation, interview, and document analysis to gain information. In addition, this study described and analyzed aboriginal children's learning experience from the perspectives of social cultural context and human interaction process. Findings indicate that most of the aboriginal students, teachers and parents feel frustrated; the aboriginal students confronted more learning problems than the Han students. This may be the reason that the Atayal cultural tradition, community environment, family background, and students' learning style are different from the current mainstream school systems. Another reason may be the education policy and teacher development process for aboriginal people do not reflect cultural differences from Han and Atayal cultures. Based on the findings, the study suggests that the cultural differences should be take into account when reforming the aboriginal education. The needs of the aboriginal students, teachers, and students should be understood from social cultural perspectives. They should be encouraged to participate in educational reform based on the attitudes of "respecting difference" and "respecting profession". In addition, the ideals of aboriginal educational reform should be implemented in the classrooms through basic or action research.
