Diigo
For other great resources to utilize please reference my diigo page. A Diigo page for those who may not know what it is, is a social bookmarking website. It works exactly like your bookmarks do on your own personal computer. However this information is saved online, and can never be lost due to a virus, unlike your regular bookmark pages. You can also see other users pages and get recommendations on other useful sites. You can interact with other users via messaging that can be sent from account to account. For teachers it is a very useful tool to take full advantage of. It allows teachers to connect, compare and discuss material about their subject matter. Teachers can share websites about worksheets or asist other teachers by suggesting lesson plan websites.
On my personal account there are pages listed to help teachers with anything from lesson plans to worksheets. There are listings for new technology in the classroom, and aids for substitute teachers.
