I offer tuition online for those at a distance or those who prefer online.
It’s fairly simple to set up. Effectively I am sitting side by side the student. We can speak, view the same problems, view each other’s writing, and I can edit work in real time..
Mathematics and physics are learned best by doing problems, which necessitates writing mathematical symbols. For this we use a graphics tablet (which can be purchased for about £30) or a laptop or tablet with stylus, together with an online whiteboard. The communications link is carried out by Zoom.
Problems and past paper questions are downloaded onto the online whiteboard so that both myself and the student can view them at the same time. There is no need to download or install any apps or software.
