Last time we discussed how attempts to automate the learning process led to the creation of the very advanced PLATO system in the 1960s for its time. Many educational courses on various subjects were developed for it. However, PLATO had a drawback — access to the educational materials was available only to university students with special terminals. The situation changed with the arrival of personal computers. […]
