促进中学生科学实践与科学认识协同发展的教学模型--以化学学科为例

A Teaching Model to Promote the Coordinated Development of Scientific Practice and Scientific Understanding of Middle School Students:Taking Chemistry as an Example

国内外科学教育界普遍认为科学实践与科学认识的协同发展是培养学生科学素养的重要途径。本文以化学学科为例,对科学实践与科学认识的内涵进行了解构,认为科学实践由“一般科学实践”“学科实验活动”“学科能力活动”组成,科学认识由“学科核心知识”“学科认识方式”组成。在阐述科学实践与科学认识协同发展必要性的基础上,提出了促进科学实践与科学认识协同发展的四维模型,对促进二者协同发展的教学设计提供了建议。

The scientific education communities at home and abroad generally believe that the coordinated development of scientific understanding and scientific practice is an important way to cultivate students'scientific competencies.Taking chemistry as an example,this paper deconstructs the connotation of scientific practice and scientific understanding,and believes that scientific practice is composed of"general scientific practice","subject core activities"and"subject competencies activities",and scientific understanding is consists of“subject cognitive patterns”and“subject core ideas”.The paper also expounds the necessity of the coordinated development of scientific practice and scientific understanding,and puts forward a teaching model that promotes the coordinated development of scientific practice and scientific understanding.
