为了适应高校与中学历史教学的不同需要,同时鉴于国家控制新增期刊的现实,本刊于2007年已改为半月刊。每月上半月刊面向中学历史教学,下半月刊面向高校历史教学及学术研究,办刊宗旨没有改变。为方便读者订阅,天津市期刊发行部门又为本刊新增一个代码,原来6-4指上半月刊,新增6-215指下半月刊。 In order to adapt to the different needs of history teaching in universities and high schools, and in view of the fact that the state controls the new periodicals, the journal has been changed to a half-monthly magazine in 2007. The first half of each month is devoted to the teaching of history in middle schools, and the second half of the month is devoted to the history teaching and academic research in universities. The purpose of the publication has not changed. In order to facilitate readers’ subscriptions, the periodical publishing department of Tianjin also added a new code for this journal. The original 6-4 refers to the first half of the month and the new 6-215 refers to the second half of the month.
