POEC探究式教学策略在生物学实验教学中的应用——以“探究酵母菌细胞呼吸的方式”为例

Application of the POEC Inquiry-based Teaching Strategy in Biology Experimental Teaching:Taking“Exploring the Way Yeast Cells Respire”as an Example

《普通高中生物学课程标准(2017年版2020年修订)》提出“教学过程重实践”的基本理念,倡导学生在课堂中积极参与、主动探究。在核心素养背景下运用POEC教学策略,采用探究式教学方法,通过情境导入,引导学生先预测、后实验,从而修正认知冲突,引发概念转变,构建知识体系。同时,探究性实验教学能够有效培养学生的科学思维和科学探究能力,充分落实生物学学科核心素养。

The Curriculum Standards for General Senior High School Biology(2017 Edition,Revised in 2020)puts forward the basic concept of“emphasis on practice in the teaching process”and advocates active participation and active exploration of students in the classroom.The POEC teaching strategy is used,and the inquiry-based teaching method is adopted in the context of key competencies.Through situational introduction,students are guided to carry out pre-test before experiment,thereby correcting cognitive conflicts,triggering conceptual changes,and building a knowledge system;at the same time,inquiry-based experimental teaching can effectively cultivate students’scientific thinking and scientific inquiry abilities,so as to fully implement the key competencies of the biology subject.
