An interactive whiteboard is a large display that connects to a computer and projector, allowing teachers and students to write, record, and interact.

The interactive whiteboard enhances the learning experience by enabling teachers to incorporate multimedia elements, such as videos and interactive games, into their lessons. It promotes active participation and helps to capture students' attention, making it an effective tool for modern classrooms.

The answer "Collective knowledge from many is of greater value than that of a single expert" best describes the use of Web 2.0 blogs, wikis, and portals to enhance teaching. These platforms allow for collaboration and contributions from a diverse group of individuals, which can lead to a wider range of perspectives and ideas. This collective knowledge can provide a richer and more comprehensive understanding of a topic compared to relying solely on the expertise of a single individual.

The correct answer is Really Simple Syndication. RSS is a web feed format used to publish frequently updated content, such as blog posts, news articles, or podcasts. The orange symbol on a blog represents the RSS feed, indicating that the blog offers a way for users to subscribe and receive updates whenever new content is published.

Blogs and wikis are both types of online platforms that allow users to create and share content. However, there is a key difference between the two. A blog is typically centered around one person, who is the main author and contributor to the content. Readers can leave comments on blog posts, allowing for interaction and discussion. On the other hand, a wiki is a collaborative platform that allows multiple users to contribute and edit content. It is not centered around one person, but rather allows for many-to-many collaboration. Therefore, the statement "Blog is usually centered around one person, while wiki is many to many" is true.
