Welcome to the TED-Ed beta website tour. I'm Logan Smalley, I'm Bedirhan Cinar, I'm Jordan Reeves, and I'm Stephanie Lo. We represent the TED-Ed team. We're going to tell you about how the website is organized, about the lessons that surround each video, how you can customize or flip your own lesson, and how you can measure the lesson's effect on your class or the world. Towards the end of the tour, we'll reveal one more major feature that directly affects every person viewing this video. Let's get started with the home page. On the home page, you'll find original TED-Ed videos, each is a lesson recorded by an actual educator that's visualized by a professional animator. You can nominate educators and animators in the "Get Involved" section of the site. The TED-Ed library can be browsed through two different lenses. Learners can use the "Series" view to browse videos thematically and based on their own curiosity. And teachers can use the browse by "Subject" view to find the perfect short video to show in class or to assign as homework. Every video on TED-Ed is accompanied by a lesson. These lessons don't replace good teaching, but they can be supplementary resources for students and teachers around the world. Let's look at this one, created by a teacher in the US and an animator in the UK. When you arrive on the lesson page, simply click play; the video will continue to play as you navigate the lesson's sections that surround it. In the "Quick Quiz" section, you'll find multiple-choice questions that check for basic comprehension of the video. You get real-time feedback on your answers and if you get one wrong, you can use the video hint. You'll find open-answer questions in the "Think" section. And in the "Dig Deeper" section, you'll find additional resources for exploring the topic. You can complete the lessons anonymously, but if you log in, you can track your own learning across the site. Just visit the "Recent Activity" feed, and you'll find answers you've saved to lessons that you've already started or completed. And now to one of the most powerful features of the TED-Ed website: flipping a lesson. Flipping a featured lesson allows you to edit each of the lesson's sections. You can edit the title as it relates to your class. You can use the "Let's Begin" section to provide instructions or context for the lesson. You can select or deselect any "Quick Quiz" question. In the "Think" section, you can add your own open-answer questions. And in the "Dig Deeper" section, you can use the resources provided or add your own. When you finish flipping a lesson, it'll publish to a new and unique URL. And because the link is unique, it can measure the progress of any learner you share it with. You can use it to measure participation and accuracy of any individual student's answers. So that's how you flip a featured TED-Ed video, We've got one more major feature to tell you about. Using the TED-Ed platform, you can flip any video from YouTube. That means you can create a lesson around any TED Talk, any TEDx Talk, but also any of the other thousands of great educational videos on YouTube, including the ones that you yourself could record, upload and flip. And through flipping these lessons, together we'll create a free and remarkable library of lessons worth sharing.
