初三化学实验复习课的教学,是一线化学教师热议的话题之一。长期以来,受多方面因素的影响,教师只能通过“口头实验”、“黑板实验”、“纸上实验”进行教学,多数学生感到这种复习课枯燥无味,所需仪器和实验现象难记住,设计出的实验方案也难理解。新课程改革对于初中化学的教学提出了新的要求,充分发挥现代信息技术之优势,建立起一个虚拟的实验室作为教学平台,优化实验复习课的教学,就能收到一箭双雕的良好效果。本文结合“常见气体制法复习网络整合课”的教学案例,从三个方面阐述了将现代信息技术运用到化学实验复习课中的教学优势。
The first three days of chemistry experiment review class teaching, is one of the topics the first-line chemistry teacher hot topic. For a long time, under the influence of many factors, teachers can only teach through “oral experiment ”, “blackboard experiment ”, “paper experiment ”, and most students feel that this review class is dull and tasteless. And the experimental phenomenon difficult to remember, the experimental program designed is difficult to understand. The new curriculum reform has put forward new requirements for junior high school chemistry teaching. By giving full play to the advantages of modern information technology and establishing a virtual laboratory as a teaching platform, optimizing the teaching of experimental review classes can receive the good results of double-edged sword. This article combines the teaching cases of “Common Gas System Review Network Integration Course”, and expounds the teaching advantages of applying modern information technology to chemical experiment review classes from three aspects.
