Google’s new ‘Page Sender’ extension allows users of the Google Classroom platform to “push” URLs to students’ computers and lets students fling URLs right back to their teacher.
Teachers no longer have to ask — and then wait! — for students to type in long URLs and web-pages, or check they’ve done so correctly. With just a single click the resources can be on their screen.
