Teachers can use these sites to create an assignment for their students, asking them to visit a certain number of sites, browse the reviews and/or booktalks and select one book from each site that interests them. From this list the student can then choose one book to read and report on. The teacher can create a book review blog (i.e. [http://bebookreview.blogspot.com/]) and have the students post their reviews online, as well as comments on other student reviews, subject to teacher approval. By utilizing Web 2.0, such as wikis and podcasts, and software such as Power Point, the presenter can create multimedia booktalks that incorporate film and videos, music and the Internet. Using a projection screen and computer, the presenter no longer has to pass around a book to show cover art, illustrations, or photographs.
