以“五环衔接”生物学实验单元教学撬动科学素质的提升

Leveraging the Promotion of Scientific Literacy Through the Unit IntegratedTeaching Mode of "Five Rings Connection" Biological Experiment

教育部等多部门提出,在教育“双减”中要做好科学教育加法,支撑服务一体化推进教育、科技、人才高质量发展。实验教学是科学教育的重要组成部分。当下的生物学实验教学存在目标不清晰、开展不充分、评价不到位等问题。研究认为,基于“五环衔接”生物学实验单元教学,即通过问题与假设的“情境驱动环”、方案设计的“拾级而上环”、方案实施的“多维量规环”、交流分析的“要素论证环”及概念建构的“反思内化环”等环节的有机衔接,对实验进行整体教学,既打破了实验教学的课时限制,又促进了学生对概念的意义建构和科学素质的提升。

The Ministry of Education and other departments have proposed that it is necessary to do a good job in scientific education in the"double reduction policy"of education,so as to support the integration of services and promote the high-quality development of education,science and technology and talents.Experimental teaching is an important component of science education.There are some problems in current biology experiment teaching,such as unclear objectives,insufficient implementation and inadequate evaluation.According to the re-search,based on the unit integrated teaching mode of"Five Rings Connection"biological experiment,that is,through the"context-driven loop"of problem and hypothesis,the"stepping up loop"of scheme design,the"multidimensional scale loop"of scheme implementation,the"element argumentation loop"of communication analysis and the"reflection and internalization loop"of concept construction,it takes the experiment as a whole.This teaching mode not only breaks the class hour limit of experimental teaching,but also promotes the meaning construction of concepts and the improvement of scientific literacy.
