Distance learning includes correspondence courses and online teaching.
In recent years people have offered lessons or courses via the internet, also called ‘distance learning’.
There was a correspondence course available in the late 1990s, but details are not available.
Online video teaching
Some teachers are offering individual lessons via video calls (e.g. Skype, Zoom). Arguments for this approach are given in two letters to the AmSAT Journal, ‘Skype Lessons’.
