The government's position on the subject will be announced next month, following a 20-month review by the education ministry that was launched in the wake of a controversy over a supposedly misleading textbook.
Government control over the school history syllabus was asserted under military rule in 1974, and ended in 2010. Since then, schools have been free to choose between a range of books produced by private publishers, which must first be approved by the education ministry.
The prospect of next month's final report bringing a return to a single, government-determined history syllabus has sparked strong opposition from liberal opposition politicians, who say it would restrict the diversity of views central to a strong democracy.
Yoon Gwan-seok, a member of the opposition New Politics Alliance for Democracy, said Mr Hwang's remarks hinted at a "political move" that would divorce South Korea from the standard practice in advanced countries, and leave it with a similar system to North Korea, Russia and Vietnam. Ms Park's supposed intolerance of dissent has been a favorite theme for her opponents.

History education has long been a fraught subject in east Asia — particularly since the 2012 election as Japanese prime minister of Shinzo Abe, who stands accused in Beijing and Seoul of playing down Japan's aggressive acts during its early-20th century colonial expansion.
Mr Abe has called for education to avoid "self-torturing views of history", and it emerged in April that textbook publishers have pared back descriptions of atrocities such as the sexual enslavement of Korean women — a development that prompted Seoul to summon the Japanese ambassador.
But South Korea's own school textbooks have also proved a source of domestic controversy. In 2013 a scandal erupted over the government's approval of a school textbook that critics said provided an excessively conservative view of history, including downplaying human rights violations under Japanese occupation and the later authoritarian rule of Park Chung-hee, the current president's father.

The book was defended by members of the ruling New Frontier party, who said it offered a balance to the broadly left-leaning content of the other seven textbooks available to high schools. The government responded by ordering revisions to all eight of the books, and in January 2014 launched a process to determine necessary reforms to the system.
Ahn Byung-woo, head of the Seoul-based Asia Peace and History Education Network, said a move by the government to reclaim control of the history syllabus would be a dangerous "backtracking to the old days".
"It will force the government's view onto students — when a conservative government takes power, the history book will become conservative," he said. "A democratic society must embrace various points of view.
