《新课标》立足于现代生活和未来发展,着眼于提高21世纪公民的科学素养,积极倡导以实验为主的多种探究活动,使学生体验科学研究的过程。所以,采用实验教学是高中化学教学的必由之路,其中的必要性和目的有诸多专家和学者都已论述过,这里不再赘述,本文只就实验教学中应该注重的原则和教材部分演示实验的改进作进一步论述。 Based on the modern life and future development, the “New Curriculum Standard” aims to enhance the scientific literacy of citizens in the 21st century and actively advocate a variety of inquiry-based activities mainly based on experiments so as to enable students to experience the process of scientific research. Therefore, the use of experimental teaching is the only way of high school chemistry teaching, the necessity and purpose of which have many experts and scholars have discussed, not repeat them here, this article only on the principles of experimental teaching and teaching materials to improve the demonstration part of the experiment For further discussion.
