化学是一门以实验为基础的自然科学,可以说化学实验是化学教学的基础,也是教师和学生学习化学知识、技能的重要的方法.通过演示实验教学,可以指导学生观察和分析实验现象,获得生动的感性知识,从而更好地掌握概念和规律.还可以培养学生的观察和分析能力,逻辑思维能力和探索动手能力,符合学生认知发展规律和学习心理特征.创设科学、高效的演示实验,以演示实验充实教学,是化学学科中体现现代素质教育思想的重要方面,有利于学生科学素养的形成.精心设计合
Chemistry is an experiment-based natural science.It can be said that chemistry experiment is the basis of chemistry teaching and an important method for teachers and students to learn chemistry knowledge and skills.Through demonstrating experiment teaching, students can be guided to observe and analyze experimental phenomena, Get vivid sensory knowledge, so as to better grasp the concepts and rules.Can also develop students’ ability of observation and analysis, logical thinking and exploration ability, in line with the law of cognitive development and learning psychology of students to create a scientific and efficient demonstration Experiments, to demonstrate experiments to enrich teaching, chemistry is an important aspect of modern quality education thinking, is conducive to the formation of students’ scientific literacy.
