通过高中酸碱中和反应相关知识的复习教学案例设计,对基于一个问题的拓展来建构学生化学知识体系的复习方法进行实践,并对如何使高考复习课堂重焕生机进行了教学反思.建构主义理论认为,只有学习者积极参与认知结构的建构学习活动才会真正出现.高三化学一轮复习是以巩固学科知识并提高知识运用能力为主旨的一种双基巩固复习.其复习任务的真正完成在于使学生把握学科知识的整体网络及内在规律,从而提高学生的思维品质和学习能力.大多数学生在高三一轮 Through the review of teaching cases related to high school acid-base neutralization reactions, the practice of constructing a review method for students’ knowledge based on the expansion of a problem is practiced, and a reflection is made on how to make the review of the classroom rejuvenate. Constructivism The theory holds that only if learners actively participate in constructive learning activities of cognitive structures can they really emerge. The third review of chemistry is a double-basis consolidation review that aims at consolidating subject knowledge and improving the ability to use knowledge. The real task of reviewing The completion is to enable students to grasp the overall network and internal laws of subject knowledge, so as to improve the students’ thinking quality and learning ability. Most students in the high three-wheeled
