What’s It Like? Mozilla’s X-Ray Goggles allows students to inspect and tweak the code found in any site on the Web, including any of the individual elements that make up a Web page. Once activated, Goggles highlights these elements as kids roll over them with a mouse. As they click one of the highlighted elements, Goggles offers a pop-up window displaying the code, alongside a preview of that element. Kids can edit the code right in the window and immediately see a preview of what their changes look like.
Pros: Discovery learning at its best: Revealing chunks of complex code on any website and letting kids edit and remix leads to powerful learning.
Cons: Some kids might need a little extra help understanding HTML structure, tags, and attributes, and the in-tool app doesn’t provide that.
Bottom line: It’s a blast to use and an easy way to get experimentation and prototyping going with plenty of student choice — kids are really in the driver’s seat!
