Internet-based language courses exploit the multimedia-rich internet platform to support language learning. They contain online multimedia language learning materials which are complete with pictures, texts and sounds. They allow learners to study whenever and wherever they want. In the information age, such virtual classrooms show remarkable vibrancy and have attracted the attention of learners and education researchers. While online language courses can supplement traditional classroom teaching, they still cannot replace physical classrooms completely as there is much room for their improvement. For example, there is a lack of interaction between teachers and students, and certain learning resources are outdated. This study analyses the strengths and weaknesses of several internet-based Chinese courses and discusses the teaching framework, features as well as the future developments and prospects of online Chinese courses.
