引言瑞科达（Rekkedal）曾经证实，在远程教育条件下，教师批改作业周期的效率会影响学生的学习积极性。他还特别地证实了较短的作业批改周期会降低辍学率。所以，对于任何远距离教育机构来说，在维持理想的教学质量的同时，确保高效的作业批改周期是非常重要的。香港公开大学 INTRODUCTION Rekkedal has demonstrated that under the conditions of distance education, the efficiency of teachers in correcting assignment cycles can affect students’ motivation to learn. He also specifically confirmed that a shorter job approval cycle will reduce dropout rates. Therefore, for any distance educational institution, it is important to ensure an efficient job approval cycle while maintaining the desired quality of teaching. Open University of Hong Kong
