基于大科学工程的初中物理跨学科实践活动设计——以子午工程探测电离层电子浓度为例

DESIGN OF INTERDISCIPLINARY PRACTICE ACTIVITIES IN JUNIOR HIGH SCHOOL PHYSICS BASED ON BIG SCIENCE ENGINEERING-TAKING THE CHINESE MERIDIAN PROJECT TO DETECT THE IONOSPHERIC ELECTRON CONCENTRATION AS AN EXAMPLE

当前经济社会发展需要跨学科人才,《义务教育物理课程标准(2022年版)》提出“跨学科实践”主题,明确指出培养跨学科人才。大科学工程综合了多学科领域的知识观念、思维方法,具有丰富的跨学科实践教育价值。以子午工程探测电离层电子浓度为例,应用其原理、科学数据等设计跨学科实践活动并进行实践。通过分析科学家的任务流程、科学家与学生的差异,设计跨学科实践活动流程;结合学生知识水平简化其中的跨学科知识;设计系列问题与活动构建脚手架辅助学生逐步学习,完成实践任务。

The current economic and social development requires interdisciplinary talents.The“Physics Curriculum Standards for Compulsory Education(2022 Edition)”proposes the theme of“interdisciplinary practice”and clearly points out the cultivation of interdisciplinary talents.The big science project integrates knowledge concepts and thinking methods in multidisciplinary fields,and has rich interdisciplinary practical educational value.Taking the detection of ionospheric electron concentration in the Chinese Meridian Project as an example,the interdisciplinary practice activities are designed and implemented by applying its principles,scientific data,etc.By analyzing the task process of scientists and the differences between scientists and students,design the process of interdisciplinary practice activities;simplify the interdiscipli-nary knowledge in combination with studentsknowledge level;design a series of questions and activities to build scaffolding to help students learn step by step and complete practical tasks.
