JEJU, South Korea/TOKYO -- Digital textbooks that make use of artificial intelligence are being adopted throughout South Korea.

The Education Ministry began a full-scale introduction in March, and already about 30% of elementary, middle and high schools nationwide have adopted the devices. The country highlighted its progress at the Asia Pacific Economic Cooperation education ministers' meeting that wrapped up in South Korea on Wednesday, but challenges remain, including regional disparities in the distribution of the devices and the level of teachers' digital literacy.
