多年来的教学实践使我感到课堂中恰当地使用下列方法是有益于产生愉悦气氛的。一、充分利用化学科的优势,依据教材的不同内容自然地导入新课化学与生产生活的密切关系是其它学科无法比拟的。用实验、实物、模型、图片、故事、趣味语言等来引入新课,使课堂一开始就能激发学生的学习兴趣,把学生引进学习情境,对活跃课堂气氛有着极其重要的作用。例如:我在进行“碳酸钙”一节的教学时,上课开始我出示了两试管澄清液体,已知一试管里是水,一试管里是石灰水,问学生能否证明哪一试管里是石灰水?不少同学 The teaching practice over the years has made me feel that the proper use of the following methods in the classroom is conducive to creating a pleasant atmosphere. First, make full use of the advantages of chemistry, according to the different content of the teaching materials naturally imported into the new class chemistry and production and life are closely related to other disciplines can not be compared. Introduce new lessons with experiments, objects, models, pictures, stories, and interesting language, so that the beginning of the classroom can stimulate students’ interest in learning and introduce students into the learning environment, which plays an extremely important role in the active classroom atmosphere. For example: When I was teaching in the section “Calcium carbonate,” I started to show two clear tubes of liquid in the beginning of class.
