一、设计思想在日常的初中化学教学中,因为面临教学时间短,课时紧张或贫困地区经济条件所限,不能在学校或课堂上完成一些化学实验,弱化了对化学实验的研究,让学生体会不到化学实验的神奇,感受不到化学学习的魅力,对化学失去了应有的兴趣。怎样能让学生在有限的时间和条件下,经历实验探究的过程,发挥实验的功效呢?我们充分利用化学学科的优势,根据学校实际和办学理念,从适应
First, the design idea In the daily chemistry teaching in junior high school, because of the short teaching time, tense hours or poor economic conditions in poor areas, can not be completed in school or classroom chemistry experiments, weakened the study of chemical experiments for students to experience Less than the magic of chemical experiments, feel the charm of chemical learning, chemical lost due interest. How to make students experience the experiment under the limited time and condition? How to make the best use of the advantages of chemistry? According to the actual situation of school and the concept of running a school,
