化学探究性实验,就是针对物质的未知性质进行研究,掌握物质的组成、属性和化学特征,同时教会学生如何将现象和性质联系起来;教师在教学中要根据实验目的,利用已知的知识、现有的条件设计探究性实验,遵循一定的原则、选择合适的实验内容、精心的设计实验思路并及时的进行反馈,从而教会学生学会判断实验的科学合理性,观察实验在操作过程中出现的现象,达到能够通过现象分析得出物质性质的目的.本文就着重对初中化学探究性实验的教学设计做了分析和研究.
The chemical inquiry experiment is to study the unknown nature of the material, to grasp the composition, properties and chemical characteristics of the material, and to teach the students how to relate the phenomena and the nature. In the teaching, teachers should make use of the known knowledge, The existing conditions to design exploratory experiments, follow certain principles, select the appropriate experimental content, careful design of experimental ideas and timely feedback, so that students learn to judge the scientific rationality of the experiment, observed in the operation of the experiment Phenomenon, to achieve the purpose of the material properties can be obtained through the phenomenon analysis.This article focuses on the analysis of junior high school chemistry exploration experiment teaching design and research.
