Kim asos solgan?
Masofaviy ta’limning ilk shakliga asos solgan shaxs — Isaac Pitman bo‘lib, u o‘z talabalariga stenografiya (tez yozish) darslarini pochta orqali yuborgan. Talabalar yozma ishlarini ham pochta orqali yuborishgan va bu jarayon ikki tomonlama bo‘lgan. Bu dunyoda rasmiy masofaviy ta’limning boshi hisoblanadi.

Keyingi rivojlanish bosqichlari:

1. 19-asr oxiri – AQShda ko‘plab universitetlar (masalan, Chicago University) masofaviy kurslar ochgan.

2. 20-asr boshida – Radio, televizor orqali darslar yo‘lga qo‘yildi.

3. 1990-yillar – Internet paydo bo‘lishi bilan onlayn o‘qitish shakllandi.

4. 2020-yildan keyin – COVID-19 pandemiyasi davrida masofaviy ta’lim global miqyosda asosiy ta’lim shakliga aylandi.
