As a new teaching mode, online courses have become one of the most important teaching methods in higher education. At present, there are still some shortcomings in online course live broadcast teaching platform including insufficient hardware support, low flexibility and weak interactivity. Meanwhile, during the entire online course teaching process, teachers do not know the overall learning effect of students in real time to determine the next teaching plan. This study presented a real-time interactive technology to enhance the interactive of the entire online course broadcast teaching platform. At the same time, it combined a monitoring method for online course terminals, servers and learning process to demonstrate students' learning effect in the whole online course learning process, and finally built the online course broadcast teaching platform. The practice test in teaching shows that the online course broadcast teaching platform can improve the teaching effect among students, which is of great significance for the improvement of teaching quality.

At present, teachers and students are unable to communicate with each other directly in the network courses so that the teaching quality has been compromised. Moreover, teaching process becomes slow in traditional teaching mode of network course. In this project, we introduced an innovative PBL (Problem Based Learning) teaching method and combined teacher and student interaction for a network course, while utilizing cloud computing. In addition, all workstations were card workstations to reduce the delay of teaching task. We designed a platform with a personnel information module and a learning service module. The learning service module covers three main functions: teaching service resources management, online coaching, and assignment submission and correction. The evaluation outcome shows that the learning outcome and learning interest was superior for students who used the PBL network teaching platform, compared to the students who didn't use this platform.
