网络教学平台中教师交流机制的设计研究

How to Facilitate Sharing of Best Practice among Teachers on Web-based Teaching Platform

依据对"大学物理课堂辅助系统"推广过程中的经验积累和总结,笔者对原有系统进行了重新设计和开发,把"共同体"的理念融入了新系统的设计中。通过构建共同体的方式在教师内部形成有效的交流机制,使教师可直接在系统平台中进行教学经验和思想的交流,共享课程资源,甚至协作教学,从而有效地实现了系统的应用和推广。

On the Web-based teaching platform, teachers are often isolated from each other. Therefore, teachers cannot benefit from exchange of best practice with their peers. Based on the lessons learnt from implementing the Tutorial System for College Physics, the researchers redesigned the system by setting up a learning community for teachers on the Web-based teaching platform. The new system has the following features. First, teachers are entitled to their personal teaching space so that they can teach in their own ways. Second, teachers can access course-specific or discipline-specific teacher communities. Third, teachers can share resources within the system. Fourth, teachers are assigned different roles but with equal status. Last but not least, teachers can access each others' personal space if they like to. Results from a small-scale empirical study show that the new tutorial system is conducive to attracting more teacher users, enhancing teachers' professional competence, and encouraging teachers to develop new ideas and use new methods in their teaching practice.
