Mozilla’s X-ray Goggles is a neat tool that helps students learn the code that powers much of what they see on the Web. X-ray Goggles is a free tool that lets you remix any page that you find on the Internet. You can install X-ray Goggles in your Chrome or Firefox bookmarks bar. Then you can launch it on any webpage. When you launch X-ray Goggles you will be able to select images and text on a page and then shown the code behind your selection. X-ray Goggles will let you then alter the code to display new things on that page. In the video embedded below I provide an overview of using X-ray Goggles.
Applications for Education
Mozilla offers a free lesson plan called Hack the News that introduces students to the features of X-ray Goggles. In the lesson students will remix a news story by putting their favorite fictional characters into the page on which the story is published.
