要学生能质疑,教师先须设好“疑”。一般情况下教师应该从以下三方面去抓设疑点:一是抓住认知结合点设疑。历史课程,有新旧知识结合点,有背景条件结合点,有思想方法结合点,我们可以就此设疑;二是抓住思维兴奋点设疑。如新旧知识间的差异处、认知结构中的空白处、史实的不确定处等,都可以用之设疑;三是抓住情感融合点 Ask students to question, teachers must be set up “suspect ”. Under normal circumstances teachers should grasp the suspicion from the following three aspects: First, grasp the cognitive combination of suspects. History courses, with the combination of old and new knowledge points, the combination of background conditions, a combination of ideas and methods, we can suspect that; second is to seize the suspicion of thinking excitement. Such as the difference between the old and new knowledge Department, the gaps in the cognitive structure, the historical facts of the uncertainties, etc., can be used as suspicion; third is to seize the emotional fusion point
