中学化学教学应该以化学知识为载体,培养学生的科学素养、科学方法和科学思维,新课程倡导“自主、合作、探究”的学习方式,化学实验在科学探究中具有不可替代的作用,但纵观现在一些化学课堂教学,在化学实验教学中存在着若干误区。本文试图从以下几个方面加以分析。一、忽视实验背景知识,实验教学指向不明中学化学实验是为化学教学服务的,但我们发现有些教师在实验教学时,化学实验游离于化学教学本身,实验目的不明确,对实验原理、实验设计、实验条件控制等未讲明,为实验而实验,实验与化学概念的形成或探究教学的进行没有很好的结
Chemistry teaching in middle school should take chemical knowledge as the carrier to train students’ scientific literacy, scientific method and scientific thinking. The new curriculum advocates the learning mode of “autonomy, cooperation and inquiry”. Chemical experiments play an irreplaceable role in scientific inquiry, However, looking at some chemistry classroom teaching nowadays, there are some misunderstandings in chemistry experiment teaching. This article attempts to be analyzed from the following aspects. First, ignoring the experimental background knowledge, experimental teaching points to unknown chemistry experiment is for chemical teaching services, but we found that some teachers in experimental teaching, chemical experiments free chemistry teaching itself, the purpose of the experiment is not clear, the experimental principle, experimental design , Experimental conditions such as control did not say experiment for the experiment, the formation of experimental and chemical concepts or to explore the teaching is not very good knot
