The Internet can free students from the limits of time and space. Network technology and communication media thrive in an information society. Students can instantly and conveniently obtain the information they need while writing and receive feedback and different perspectives for mutual communication, discussion and interaction. As a result, students can experience a new way to practise writing (Yang & Chan, 2008). In recent years, Webbased educational systems have contributed to the emergence of new research and development to prepare highly qualified teacher candidates (Calandra, Lai & Sun, 2004).
