In this chapter, we have seen two ways of adding real-time communication and interaction to our Moodle course, firstly, by using Google+ Hangouts and secondly, by using Google+ Hangouts on Air. This interaction can be very useful, particularly for allowing students to communicate with each other and the teacher. For distance education, synchronous tools solve several problems that come from students being in different locations, allowing us to share desktops, presentations, sketchpads, voice, and video.

In the next chapter, we will finally conclude this book with some general aspects on copyright, licensing, safety related to multimedia works, and online collaboration.
