摘要
化学实验是进行科学探究的重要方式。学生具备基本的化学实验技能是学习化学和进行探究活动的基础与保障。因此,在化学教学中,教师可发挥演示实验这一辅助教学手段的特殊作用,将抽象的化学知识变得具体化,引发学生的感性认知,让学生更好地理解与掌握化学理论知识。文章探究提高初中化学演示实验有效性的途径。
Chemical experiment is an important way to carry out scientific research.Students have basic chemical experiment skills,which is the basis and guarantee of learning chemistry and carrying out inquiry activities.Therefore,in chemistry teaching,teachers can play a special role in demonstrating experiment as an auxiliary teaching method,which can make abstract chemical knowledge concrete,arouse students'perceptual cognition,and make students better understand and master the chemical theory knowledge.This paper explores the effective ways to improve the chemical demonstration experiment in junior middle school.
