This kind of consciousness can make students learn to think and deal with problems actively. With the new round of basic education curriculum reform, more and more attention has been paid to students thinking innovation and creativity. However, under the new curriculum standard, junior high school history teaching is still insufficient in cultivating students problem awareness. This paper will analyze the importance, problems and measures of cultivating students problem consciousness, hoping to provide reference for cultivating students problem consciousness in junior high school history class under the new curriculum standard.展开更多
