在传统的实验教学中,特别是演示实验,存在着学生看不清楚实验现象和过程,重点不够突出,再现性差,时间长等问题。这无疑对学生形成化学概念,理解和巩固化学知识,培养学生观察问题、分析问题、解决问题、初步掌握化学实验技能是不利的。而将现代媒体与传统教学相结合,则可较好地解决以上问题。为了适应中学化学实验教学改革的需要,本文将从以下三个方面来探讨如何应用现代媒体加强中学化学实验教学。
In the traditional experimental teaching, especially the demonstration experiment, there are problems such as the students can not clearly see the experimental phenomenon and process, the emphasis is not prominent, the reproducibility is poor, and the time is long. This undoubtedly creates a chemical concept for students, understands and consolidates chemical knowledge, and it is unfavorable for students to observe problems, analyze problems, solve problems, and initially grasp chemical experiment skills. The combination of modern media and traditional teaching can better solve the above problems. In order to adapt to the needs of the middle school chemistry experiment teaching reform, this article will discuss how to use modern media to strengthen the middle school chemistry experiment teaching from the following three aspects.
