摘 要：化学是一门以实验为基础的学科，化学实验是中学化学教学的一个重要组成部分，在中学阶段培养学生的化学实验技能是整个教学环节中的最重要一环。随着新课改的深入和素质教育的实施，新课改背景下的高中化学实验教学质量的提高已成为每一位高中化学教师急需解决的问题。从目前情况来看，由于实验条件、实验成功率和环境保护等因素的影响，高中化学实验教学中存在实验课开设不足和实验效果不好的情况。作为中学化学教师有必要针对存在的这些不足采取相应的改进措施。本文对苏教版高中化学必修1中的化学实验进行了研究、分析，并对有关实验的改进进行了探讨，旨在为中学化学教师开设高中化学必修1教材中的化学实验提供参考。66135

Abstract : Chemistry is a subject based on experiment, and chemistry experiment is an important part of the middle school chemistry teaching in the middle school stage. Cultivation of chemical experimental skills of students is the most important thing in teaching. With the deepening of new curriculum reform and the implementation of quality education, the quality of high school chemistry experiment teaching under the background of new curriculum reform raising has become the problem for every high school chemistry teacher need to solve. Judging from the current situation and because of the influence of the experimental conditions, the success rate of experiment and environmental protection and other factors, there are some bad situations such as the experimental course is not enough and the experimental effect is not better exists in high school chemical experiment's teaching. As a middle school chemistry teacher, it is necessary to take corresponding measures to solve these problems. This article analyzes the shortcomings of the current experiment in middle school chemistry compulsory textbook 1st, aimed at providing reference for middle school chemistry teachers demonstrate chemical experiments in middle school chemistry compulsory textbook 1st.
Keywords : middle school chemistry compulsory 1st , experiment, shortcomings , improve

化学课程标准指出：教师在教学中应高度重视和加强实验教学，充分发挥实验的教育教学功能【1】。我国义务教育阶段的化学课程主要培养学生在“知识与技能”、“过程与方法”、“情感态度与价值观”三个方面的发展，旨在提高学生的科学素养。高中化学课程更是以学生适应现代生活和未来发展的需要为立足点，以提高 21 世纪公民的科学素养为着眼点，构建了“知识与技能”、“过程与方法”、“情感态度与价值观”相融合的综合性化学课程目标体系。
