化学是一门实验性学科,其教学效果与实验教学质量密切相关.化学实验教学贯穿于化学学科的始终,演示实验是其基础,对化学实验教学有示范作用.演示实验教学必须具有针对性、示范性,确保学生有效观察实验现象,在激发学生课堂积极性的同时,有效地解释现象,巩固知识.学生在演示实验的教学过程中,通过积极的思维观察,帮助学生们养成科学的实验思路.本文我将从演示实验的实践教学出发,谈谈对演示实验教学的体会.
Chemistry is an experimental subject, and its teaching effect is closely related to the quality of experimental teaching.Chemical experiment teaching runs through the discipline of chemistry, demonstrating experiment is its foundation and exerting demonstration effect on chemistry experiment teaching.Demonstrating experiment teaching must have pertinence, Demonstration, to ensure that students effectively observe the experimental phenomenon, to stimulate students’ enthusiasm in the classroom, while effectively explain the phenomenon and consolidate knowledge.Students in the demonstration experiment teaching process, through positive thinking to help students develop scientific experiment ideas In this paper, I will start from the practical teaching demonstration experiment, to talk about the demonstration of experimental teaching experience.
