基于PCRR论证模型的批判性思维的培养——以“DNA的结构”为例

Fostering Critical Thinking Based on the PCRR Argumentation Model—A Case Study of “The Structure of DNA”

摘要: 批判性思维是科学思维的核心，论证教学是发展该能力的重要途径。本文以“DNA的结构”一节教学为例，探索如何运用PCRR论证模型开展论证教学以培养学生的批判性思维。教学设计基于PCRR模型的四个环节，引导学生针对DNA的结构特征进行科学论证，为高中生物学教学中批判性思维的培养提供实践参考。

Abstract: Critical thinking lies at the heart of scientific thinking, and argumentation instruction is a key means of developing this ability. Taking the teaching of the section “The Structure of DNA” as an example, this paper explores how the PCRR argumentation model can be used to conduct argumentation teaching in order to cultivate students’ critical thinking. The lesson design is based on the four stages of the PCRR model, guiding students to construct scientific arguments regarding the structural characteristics of DNA, thereby providing a practical reference for the cultivation of critical thinking in high school biology education.
