化学实验在中学化学教学中的影响和作用
The influence and function of chemical experiment in middle school chemistry teaching
摘 要
化学是一门以实验为基础的学科,实验是化学最重要的特征之一。随着新课程改革的不断深入,新课程理念深入人心，化学实验教学被更加重视,有关化学实验的教育功能的研究越来越多地引起人们的关注。《普通高中化学课程标准(实验)》对'突出化学学科特征,更好地发挥实验的教育功能'提出了四方面的建议,这就要求中学化学教师在日常教学实践中要增强挖掘化学实验教育功能的意识,践行对化学实验教育功能的开发,反思现有教学条件下最优化地发挥化学实验教育功能的方法。目前对化学实验教育功能的研究大都落实在具体实验或某一功能上,缺乏系统的研究,更鲜有人依据教学实际,有目的、有选择地开发化学实验的教育功能。针对这一情况，本文从化学实验教学的相关点切入，在研究了相关文献的基础上，分析了如何才能把化学实验教学在化学教学中的促进作用给放到最大，更有效地服务于学生全面发展。
Abstract
Chemistry is a discipline based on experiments. Experiment is one of the most important characteristics of chemistry. With the deepening of the new curriculum reform, the new curriculum concept is deeply rooted in the hearts of the people. The chemistry experiment teaching has been paid more attention. More and more attention has been paid to the research on the educational function of the chemical experiment. The general high school chemistry curriculum standard (Experiment) puts forward four suggestions to 'highlight the characteristics of the chemistry subject and give full play to the educational function of the experiment'. This requires that the middle school chemistry teachers should strengthen the consciousness of excavating the function of chemical experiment education in the daily teaching practice, practice the development of the function of the chemical experiment education and reflect on the existing teaching. The method of optimizing the function of chemical experiment education under the conditions of learning. At present, most of the studies on the function of chemical experiment education are carried out in specific experiments or some functions, lack of systematic research, and few people have the educational function of developing chemical experiments on the basis of teaching practice. In view of this, this article from the relevant point of the chemical experiment teaching, based on the related literature, analysis how to make the chemical experiment teaching in the teaching of chemistry in the promotion of the maximum, more effective to serve the overall development of the students.
