Abstract: Network teaching platform provides a supporting environment for teachers and students to carry out distance education. Based on Windows 2003+. NET Framework+SQL Server+IIS environment, by adopting three main technologies including synchronous update of file catalog, dynamic tree directory and Ajax asynchronous communication, the study develops general network course teaching platform which possesses autonomous construction function. The advantage of this teaching platform is that, teachers don’t need to modify the source program of network course platform but only by adding teaching contents to the general network course teaching platform according to teaching needs, they may create personalized network course which can also be used by multi discipline. The experimental result indicates that, the research system can help the teachers to design network course more effectively and solve the bottlenecks in network course creation.
