A summary report on the Space Physics practical education in 2022
-
摘要: 空间科学与技术专业实践教育对于本科生空间物理学习具有重要意义. 近年来，中国科学技术大学地球和空间科学学院空间科学与技术专业基于国家大型空间环境地基综合监测系统——子午工程的链条观测优势，开展全方位、多角度的本科生暑期专业实践教育. 在实践教育中，老师们生动详实地为同学们讲解实习的各项内容，带领同学们学习观测数据的处理与分析，并且参观子午工程台站；同学们使用多种观测设备，学习了光学、无线电和磁场等不同探测技术，了解了不同探测仪器的探测原理，掌握了科研软件的使用方法，并可视化分析空间天气事件期间近地空间环境的变化特征. 最后，同学们还进行了实践教育总结汇报. 通过参加空间科学与技术专业实践教育，同学们真正接触科研工作，成功地克服了初次尝试科研时的“忐忑不安”，不仅提升了自主学习、小组分工合作等实践能力和科学素养，而且开阔了眼界，为更深入地了解空间物理学打下基础.Abstract: Hands-on education is of great importance for undergraduate students studying Space Physics. In recent years, the School of Earth and Space Sciences at the University of Science and Technology of China has conducted extensive undergraduate summer professional practical education based on the advantages of the Chinese Meridian Project's chain observation. Teachers guide students in learning about the processing and analysis of observation data, take them to the Chinese Meridian Project sites, and thoroughly explain to them the numerous facets of practical education. Students learn many detecting technologies, including optical, radio, and magnetic fields, as well as the concepts of various instruments used for detection, as well as how to use scientific data and research tools and visualize the change characteristics of the near-Earth space environment during space weather events through data analysis. Finally, the students conducted a summary report of their practical education. Through participating in space physics practical education, students truly engage in scientific research, successfully overcoming the "anxiety" of initial attempts at scientific research. This not only improves their practical abilities and scientific literacy such as independent learning and teamwork but also broadens their horizons and establishes a foundation for further understanding of Space Physics.
