When personal computers were launched in the 1970s, the use of information technology (IT) equipment was limited to the handling of business transaction and data storage. Nowadays, with the help of the Internet and coupled with the affordable price of personal computers, tablet computers and other handheld devices, people can perform Web surfing and information searching using a broadband Internet connection through wireless services provided by Wireless Fidelity (WiFi) and the third (3G) and the fourth generations (4G) cell phone networks. Now, the Internet becomes a technology enabler for “anytime-anywhere business”, as well as for “anytime-anywhere learning” (Boisvert, 2000). At the same time, educational institutions are shifting their ways of delivering services from merely factual and procedural knowledge dissemination in the classrooms to online teaching through electronic learning (E-learning) systems such as Moodle (https://www.coursera.org/), have entered into the education service market for delivering free online courses for learners all over the world. Obviously, the success of these teaching Web sites and services rely on the blending of the use of Web technology, multimedia tools, and communication applications and tools, such as online forums, for facilitating communications between their stakeholders, i.e., learners and instructors.
