“三疑三探”教学模式在初中化学教学中的应用——以“一氧化碳”一单元为例

The Application of"Three Doubts and Three Explorations"Teaching Mode in Chemistry Teaching of Junior High School——Taking"Carbon Monoxide"Unit as an Example

"三疑三探"教学模式得到了全国大多数中小学的应用,起源于河南省西峡第一高中杨文普在教学实践中探索出的一种教学模式。"三疑三探"教学模式主要包含了设疑自探、解疑合探、质疑再探以及拓展运用四个环节。本文通过介绍"三疑三探"教学模式的具体内容和目的,以及在初中化学课堂上的运用,促使更多的教师能够把此模式运用到课堂中去。

The teaching mode of"Three Doubts and Three Explorations"has been applied in most elementary and secondary schools throughout the country.It originated from a teaching mode explored by Yang Wenpu in the teaching practice of the No.1 High School in Xixia,Henan Province."Three Doubts and Three Explorations"teaching mode mainly includes four aspects:setting up doubts and self exploration,exploring together,questioning and re-exploring and expanding and applying.This paper introduces the specific content and purpose of the"three doubts and three probes"teaching mode and its application in junior high school chemistry class,so as to encourage more teachers to apply this mode to the class.
