Sharing information with ICT

Sometimes people cannot meet face to face because they live in different countries. A video meeting solves this. People see and hear each other on screens, show a picture or a table to everybody, and send documents. There is one problem: time. When it is noon in Cairo it can be early morning in a city far to the west and late afternoon in a city far to the east. We call this the time difference. A good meeting time is a time when everybody is awake and not at dinner or asleep. After the meeting, someone writes short notes: what we said and what we decided. Then everyone has the same information. In Egypt the Ministry also keeps recorded lessons, so a pupil who missed a lesson, or did not understand it, can watch it again.
