高中生物学校本课程单元整体开发的实践研究——以利用“新冠肺炎”为主题开发“传染病与防控”课程为例

A Practical Study on the Integral Development of the School-based Biology Course Unit——The Practice of Developing the“Infectious Disease and Prevention”Course with the Novel Coronavirus Pneumonia as a Thematic Issue

单元整体课程内容的开发要聚焦生物学概念体系,其教学的设计要指向学科核心素养的达成。应基于单元整体概念体系和教学目标开发课时教学。以“新冠肺炎”为主题开发“传染病与防控”单元整体校本课程中,以“新冠疫情”为单元整体教学情境,设计“情境—问题—活动—评价”的教学主线,帮助学生建构“传染源与感染”、“传播途径”、“传染病的防控”等生物学概念体系。同时,通过主动学习,解决真实生物学问题,发展学科核心素养。进一步开发研究还需注重课程的动态性、探究性、衔接性、开放性。

The integral development of the course content of a unit should focus on the biological concept sys⁃tem,and its teaching design should be oriented at the achievement of the core competency of the subject.Corre⁃sponding classroom instruction should be developed based on the overall concept system of the unit and the learn⁃ing objectives.With the theme of"Novel Coronavirus Pneumonia",develop the whole school-based course of"In⁃fectious Diseases and Prevention".In developing the“Infectious Disease and Prevention”course with the novel Coronavirus pneumonia(COVID-19)as a thematic issue,the novel coronavirus pandemic is integrated in a unitlevel teaching and learning context.The instruction is designed with a“Situation/Context-Issue/Problem-Activity-Assessment”main clue that students can be helped construct such a biological concept system as“infectious sources and infection”,“transmission channels”and“prevention and control of infectious diseases.”Meanwhile,students actively learn how to solve real biological problems and develop the core competencies of the subject.Fur⁃ther research and development will be required attention to the dynamics,inquiry,relevance and openness of the courses.
