From the Boston Globe:
When the book was first criticized, early in the school year, the district formed a committee to review it that was made up mostly of administrators and teachers. That panel recommended on Oct. 30 that the book be removed from the curriculum because there wasn't enough time to provide all the historical context that would be needed to render a balanced lesson. Superintendent Perry Davis supported the recommendation, and the School Committee took it under advisement.
In the meantime, middle-school English teachers expressed a "strong interest and willingness," Davis told the committee, to expand the unit with other survival stories that show the period from the Korean perspective. That led to a reversal of the original recommendation.
