Teaching and Learning are two sides of the same coin but they are different.
A student learns using the web and a spreadsheet.
A teacher gives an assignment that could be solved using the web and spreadsheet, and ideally using different tools.
When we teach our students using TeleComputing tools we are E-Teaching and the students are doing E-Learning
When we go to an online conference we are doing E-Learning and the presenters, E-Teaching.
