From my perspective, the appropriate use of web2.0 technologies is related to the outcomes of learning. For my understanding of appropriate use, it means the way web2.0 technologies should be correct, and the affordance of the web2.0 technologies should be correct,which requires the certain kind of technology chose should adapt to related learning and teaching environment.

For example, Wiki, as one of the Web 2.0 components, indeed it can be used to enhance the teaching and learning process. Wikis in particular actively involve learners in their own construction of knowledge(Boulos, Maramba, &Wheeler, 2006).

Wikis are an excellent tool on collaborating work in an online environment, more specifically, they called editable websites where anyone can visit, read, reorganize and update the structure and content as they preferred. As for the teaching and learning, this ease of editing means that the teachers and students can easily expand a forum that can be used for discussion, posting assignments, and various collaborative projects. Wikis have been successfully used in education as early as 1999 (Guzdial 1999). As with most computer technology, their educational uses were first pioneered by computer science academics (Edington et al. 2005) but now the wiki technology is starting to penetrate all fields of academia and the use of wikis for educational (and other ) applications is increasing.(Edington et al. 2005, Schwartz et al. 2004)
