Despite protracted public opposition to the scheme including a late July rally that drew some 90,000 people, officials resisted calls to scrap it from local primary and secondary schools, saying it was aimed at instilling a greater sense of national pride and belonging towards China.
"The important thing is to ensure that the public concern or the parents' and the students' worry about the so-called brainwashing will not happen," said Hong Kong's number two official, Carrie Lam.
"But that will only be achievable by more communication between the various stakeholders and by putting the trust in the school sponsoring authorities and the individual schools."
Hong Kong officials say schools may adopt the curriculum voluntarily with the scheme not to become mandatory until 2015.
The protests are a continuation of demonstrations that first flared on Saturday, with many pledging to fight on including a small band of hunger strikers. One middle-aged female academic was stretchered off late on Monday for medical treatment after going on hunger strike for over 40 hours.
While the curriculum touches on some negative aspects of contemporary Chinese history including unfair land grabs by corrupt officials and a toxic milk powder scandal, it makes no mention of the June 4, 1989, crackdown on pro-democracy protesters in Beijing's Tiananmen Square.
