The document discusses using web2 applications to facilitate distance education. Web2 allows for increased interactivity as it enables many people to publish and share information in different formats. This matches well with the key features of distance education, such as interaction between students and instructors regardless of location or time. Some examples of web2 applications that could be used include social networks, wikis, podcasts, and polling tools to engage students and encourage collaboration and sharing of information. Research discussed found that web2-enabled learning will be more learner-driven, mobile, social, and lead to new forms of certification. A personalized teaching system based on web2 was also proposed.
