初中学生接触化学的时间较短,他们从认识单个化学仪器的用途、实验操作的禁忌开始接触化学实验,到能设计简单的实验方案、根据内容组装实验仪器.中间的学习过程就是让学生思维不断完善的过程,同时也是增进他们对实验内容理解的的过程.学生对实验有了深刻的理解,操作起来才能有的放矢的进行探究,才能更好地达成实验目的,从而为化学的学习起到促进的作用.但化学只依靠单一的实验仪器是无法体现化学 Junior high school students have a shorter exposure time to chemistry. They begin to contact chemical experiments by understanding the use of individual chemical instruments, the taboos of experimental operations, and the ability to design simple experimental programs and assemble experimental instruments based on content. The middle learning process is to allow students to think continuously. The process of improvement is also the process of enhancing their understanding of the content of the experiment. Students have a deep understanding of the experiment and can operate it with targeted exploration to achieve the purpose of experimentation better, thus promoting chemistry learning. Role. But chemistry can only reflect chemistry by relying solely on a single laboratory instrument.
