Answer to Question 1
E-learning takes advantage of a variety of collaboration tools to function. Discussion forums, shared workspaces, blogs, and wikis offer useful ways for instructors and students to interact asynchronously. Virtual worlds, web conferences, and interactive video systems support synchronous interaction.
Web-conferencing systems features make them ideal for e-learning as participants can see what the meeting host selects to show-presentation slides, a software application, a website, or an interactive whiteboard. They can interact using webcams and microphones or submit comments and questions using text chat. Other features include file sharing, polling, and the ability to create breakout rooms so small groups can work together privately and then come together with the other groups later to report. The virtual classroom also offers features to accommodate the human element and gives students ways to express themselves nonverbally. They can also pass private notes to one another during a class.
