由于中考化学考试采取等级制,因此初中阶段的化学课时相对较少.但初中化学教学内容偏多偏重,如果教师仍然采取填鸭式教学方法,使学生只是单纯地用耳朵听,不利于学生理解与掌握化学知识,课堂效率低下.因此,要想让学生快速掌握知识,教师就要建立化学高效课堂.下面结合自己的教学实践就建立初中化学高效课堂谈点体会.一、做好充分的备课工作“做好充足的准备工作是成功的一半”.做好充足的备课工作,能够降低化学教学难度,提高化 Due to the grading system adopted in the senior high school entrance examinations, the chemistry classes in junior middle schools are relatively rare, but the contents of chemistry teaching in junior high schools tend to be more stressful. If the teachers still adopt the cramming teaching method, the students just listen to them with their ears, Therefore, in order to enable students to quickly grasp the knowledge, teachers should establish a chemical efficient classroom. The following combination of their own teaching practice on the establishment of junior high school chemistry and efficient classroom talk about experience .A full preparation for the lesson “Adequate preparation is half done. ” Adequate preparation work, can reduce the difficulty of chemistry teaching, improve
