"Course Builder is our experimental first step in the world of online education. It packages the software and technology we used to build our Power Searching with Google online course. We hope you will use it to create your own online courses, whether they're for 10 students or 100,000 students. You might want to create anything from an entire high school or university offering to a short how-to course on your favorite topic.
Course Builder contains software and instructions for presenting your course material, which can include lessons, student activities, and assessments. It also contains instructions for using other Google products to create a course community and to evaluate the effectiveness of your course. To use Course Builder, you should have some technical skills at the level of a webmaster. In particular, you should have some familiarity with HTML and JavaScript."
"You can use Vyou embed a video booth that students can go at any time of day to ask you questions. The video booth gives the impression that you are always available and builds some presence on your course. The messages students send you are delivered to an inbox and you are notified so that you can answer them. Vyou also has a very handy mobile app so you can answer the questions where ever you are on your iPhone or other mobile device.
