I can't find the original press release, but the English language edition of the JoongAng Daily reported:
Elementary, middle and high school students will be learning with electronic textbooks in addition to currently used paper textbooks starting next year, the Education Ministry said yesterday.
The announcement came as the ministry continues to promote the idea of giving more freedom to textbook publishers to set prices and for schools to decide what textbooks and learning material formats for use in the classroom. Price setting will be made flexible from 2012, according to the ministry.
The ministry’s decision will pave the way for ordinary books on the market and some books written by schoolteachers to be officially adopted as textbooks only if the ministry or local education offices approve. Since that means some textbooks could be even thicker and heavier than conventional textbooks that are normally no thinner than 300 pages, the Education Ministry began thinking about using e-textbooks on CD-ROMs.
