When face-to-face tutoring is not an option, I teach online using Skype or Google Hangouts. I have been tutoring online for a number of years, teaching both secondary school/high school and university students from all over the world. There is no need to go anywhere and all the student needs is a laptop.
The student can follow what I am doing via screen sharing and I use a drawing program called SketchBook that allows me to draw the structures and formulae. I save the lesson notes to a JPEG file which I email to the student after the lesson so there is no need to take notes and waste time.
The student can show his or her work via their laptop camera so the session is highly interactive and effective.
