Knowledge sharing, as a kind of social behavior that incorporates collective intelligence to achieve a certain goal, has become a remarkable developing trend in recent years. Under the context of traditional teaching, this study aims to explore the manner in which students become effective in sharing knowledge to help optimize course design and improve our existing education.,Among 195 university students taking an elective, the effects of different incentives on group performance in completing tasks is explored on the basis of a randomized experiment.,Results show that intra-group cooperation can be helpful to student performance, whereas intra-group competition neither improves nor worsens student performance. The former is mainly driven by reciprocity, especially for that stimulated by inter-group competition, whereas the latter is stimulated by egoism. Thus, proper reciprocity can promote student behavior to increase voluntary contribution. In addition, intra-group differences do not interfere with group performance, especially task-oriented groups.,Certain suggestions are proposed to improve the curriculum design in large classrooms. Forming groups is the best way to strengthen student knowledge sharing. Within task-oriented groups, the incentives of inter-group competition can encourage students to deepen intra-group cooperation and thus effectively improve group performance under the conditions of external competition.

组内竞争性激励对知识共享绩效结果的影响：来自随机实验的证据

知识共享作为一种通过集体智慧实现特定目标的社会行为，近年来已成为一个显着的发展趋势。在传统教学的背景下，本研究旨在探讨学生如何有效地共享知识，以帮助优化课程设计并改善我们现有的教育。在195名大学生中，选修课目中，不同激励措施对小组绩效的影响结果表明，小组内部的合作对学生的学习成绩有帮助，而小组内部的竞争既不能提高学生的学习成绩，也不能降低学生的学习成绩。前者主要由互惠驱动，尤其是在群体间竞争的刺激下，而后者则受到利己主义的刺激。因此，适当的互惠可以促进学生的行为以增加自愿捐款。此外，小组内部的差异不会干扰小组的绩效，尤其是面向任务的小组。提出了一些建议，以改善大型教室的课程设计。组成小组是加强学生知识共享的最好方法。在以任务为导向的小组中，小组间竞争的动机可以鼓励学生加深小组内部的合作，从而在外部竞争条件下有效地提高小组的绩效。提出了一些建议来改善大型教室的课程设计。组成小组是加强学生知识共享的最好方法。在以任务为导向的小组中，小组间竞争的动机可以鼓励学生加深小组内部的合作，从而在外部竞争条件下有效地提高小组的绩效。提出了一些建议来改善大型教室的课程设计。组成小组是加强学生知识共享的最好方法。在以任务为导向的小组中，小组间竞争的动机可以鼓励学生加深小组内部的合作，从而在外部竞争条件下有效地提高小组的绩效。
