Their Advantages and Disadvantages:

Advantages

Interaction, communication and collaboration

It helps build a sense of community, increases interaction and communication among the instructor, students, and other people, and promotes collaboration and resource sharing. 

Knowledge creation

It enable students to “become creators of knowledge.” Web 2.0 technologies give students “the opportunity to create content themselves instead of just listening to lectures,” and this supports active and student-centered learning in which students take responsibility for their learning. Web 2.0 technologies create an environment where a teacher becomes a facilitator of learning rather than a distributor of knowledge.

Ease of use and flexibility

Web 2.0 tools are easy-to-use and flexible, explaining that using Web 2.0 tools does not require high-level technical skills. Web 2.0 tools remove time constraints by providing a more flexible learning environment that is not inhibited by classroom walls.

Writing and technology skills

Web 2.0 technologies help students become more proficient in writing and in the application of technology.

Students Become Part of the Lesson

When Web 2.0 technologies are used in a class, students become part of the lesson. They have the opportunity (or requirement) to be an active part of the class. Active participation means they add to the wiki or blog, create a presence on a social network, or become a participant in a virtual world. All of these Web 2.0 technologies can engage the students and allow them to contribute to the lesson in an active manner, thus becoming a part of the lesson.

The World Becomes the Classroom

The best way to learn is to become active. Web 2.0 technologies expand the classroom to the virtual world and allow the world to become the classroom. Because of easy access to the virtual world, the lesson can be open to anyone; it is not confined to a single classroom or a single set of students. This allows students to easily work across boundaries with others who may have different cultures, values, and interests. It is imperative that today's students have a more global perspective and Web 2.0 technologies can help to this.

 The Classroom is Available 24/7

All of the Web 2.0 technologies are Internet based. This means they are available to students 24 hours a day, 7 days a week. A student simply needs an Internet connection and he/she can be in the classroom. As a result, students can interact in a classroom environment when they are best prepared

Disadvantages:

Uneasiness with openness

Open nature of Web 2.0 technologies is still new to many students. Some students are very uncomfortable with the openness and are reluctant to participate in class activities that utilize Web 2.0.

Web Resources Can Be Vandalized or Sabotaged: Online access is wonderful, but it can be like leaving your valuables on a table in your front yard. Anyone can see your work. If non class members have access to the wiki or virtual world, they can disrupt the class or cause damage (sabotage) to the environment. 

Technical problems

Students who have older computers often have technical issues when using Web 2.0 tools. It was also noted that some Web 2.0 tools are “still a little primitive,” having technical glitches and might not work well with current course management systems. 

Time

While Web 2.0 tools are relatively easy-to-use, it still takes time to learn and manage new technologies.

Plagiarism

Plagiarism is very easy in the online world; just copy the paragraph or sentence from the source and paste it to the blog or wiki. This can be a quick response to a question or assignment that results in plagiarism.
