随着网络技术、计算机、等技术的日益不断进步,虚拟实验不仅在科学研究领域而且在学生实验中也有了较为广泛的应用,对于过去在教学过程中老师用传统的实物进行实验而言,现在课程虚拟实验有它更大的优势,过去很多实物实验在操作过程中是存在很多危险性的,例如,更多的化学实验会发生很多化学反应,部分化学反应会伤人,还有的化学实验在操作过程中会发生爆炸现象;过去在实物操作实验时部分实验由于资金短缺或者实验样品尤为珍贵,实验太大是不能实现的,只能靠老师的讲解,学生看不到任何现象自己理解,如今实现课程虚拟实验后,在教学过程中遇到的任何实验都是可以看得见实验过程的,既解决了教育资金短缺问题,同时,又让学生对该实验有了深刻的印象,因此初中化学课程虚拟实验在教学过程中的应用是十分必要的。
With the continuous improvement of network technologies, computers and other technologies, virtual experiments have been widely used not only in the field of scientific research but also in student experiments. For teachers who used traditional physical experiments in the teaching process in the past, Virtual lesson experiment has its advantages. In the past, many physical experiments have many dangers during the operation. For example, more chemical experiments will cause many chemical reactions, some chemical reactions will hurt people, and some chemical experiments In the operation process will explode phenomenon; in the past in the physical operation experiment part of the experiment due to lack of funds or experimental sample is particularly precious, too large experiment can not be achieved, only by the teacher’s explanation, the students can not see any phenomenon to understand, Now that the virtual experiment in the curriculum is realized, any experiment encountered in the teaching process can see the experimental process, which not only solves the shortage of education funds, but also impresses the students with the experiment. Therefore, junior high school The application of the virtual experiment of chemistry course in the teaching process is very necessary.
