摘要：The purpose of this study was to investigate the leadership roles and practices of the principal in improving school effectiveness. This descriptive study involved the principal , counselor, and 11 teachers from the Tonsley Park Primary School in South Australia. The findings showed that all respondents generally regarded team leader as the most important role, while supervisor was rated as the least important. Of the 20 tasks observed, generally revealed that a principal should work cooperatively with staff to ensure more effective use of their skills. While, the task of a principal in making decisions on staff development programs was not necessarily expected by the practicing teachers. All respondents considered organization coordination as the most important area within which a principal should provide more leadership, while curriculum or instructional improvement and innovation was regarded as the least important.
