By Lee Hon Sing WebEx provides an online meeting environment in which a presenter can communicate with the audience through powerpoint slides, word documents and screen sharing. It is thus a very useful environment for conducting online classes and discussion meetings. It has also tools such as chat and polling facilities which enhance the interaction between the presenter and the audience. The sessions can be recorded for future referencing. In this presentation I shall give a quick demonstration and share on my experience on using WebEx for my seminar classes.
