化学是一门以实验为基础的自然科学。在高中化学教学中,老教材把着眼点放在理论水平与知识技能的提高上。把实验的最终目标定位于知识的验证和基础操作的熟练程度上。新教材中实验教学的目标是:激发学生学习化学的兴趣,创设生动活泼的教学情境,帮助学生理解和掌握化学知识和技能,启迪学生的科学思维,训练学生的科学方法,培养学生的科学态度和价值观等新鲜教学理念。新教材的教 Chemistry is a natural science based on experimentation. In high school chemistry teaching, old textbooks focus on the improvement of theoretical level and knowledge and skills. The ultimate goal of the experiment is to verify the knowledge and proficiency in basic operations. The objectives of experimental teaching in the new textbooks are to stimulate students’ interest in learning chemistry, create a lively teaching situation, help students understand and master chemistry knowledge and skills, inspire students’ scientific thinking, train students’ scientific methods, and cultivate students’ scientific attitudes. Fresh teaching concepts such as values. Teaching of new materials
