Google Docs has many useful features for helping students develop writing skills. When I recently opened a Google Document to plan a teacher training on Using Google Docs to Facilitate a Writing Workshop I was pleasantly surprised to find a new and powerful integrated research feature which couldn't be easier to use. Just pull down the Tools menu, click on Research and search for information in the research pane that appears on the right side of the screen. Users never have to leave the page.
