残雪消融，微微南来风，九方校园春意浓。2022年2月28日晚，株洲市九方中学学术报告厅传出一阵阵欢声笑语，九方中学SSI-L项目组团队师生以及高一宏志班的部分同学，以最热烈的掌声迎来了他们期盼已久的尊贵客人——学校SSI-L项目组外聘专家、中国中车轨道交通研究所工程师刘浏。
SSI-L项目是在科学素养提升联盟(AISL)的背景下，由北京师范大学中国基础教育质量监测协同创新中心与美国北卡罗来纳大学教堂山分校大学联合发起的科学教育合作项目。湖南省株洲市九方中学自2020年起，作为全国首批（SSI-L）项目基地校，持续立足校情学情，积极推进SSI-L教学实践与探索，项目组团队师生先后完成了《为什么肺癌患病率逐年上升？》、《高铁站的区位选址应该在市区还是郊区？》、《智轨与城市交通问题》等社会性科学议题的选题和探究，圆满完成规划中的第一轮SSI-L教学，初步达成了学科核心素养和科学情感态度价值观培养的双向育人目标。
在高一学段第二轮SSI-L教学中，项目组师生选择的议题是《智轨与城市交通问题》。为突破议题教学中驱动性问题探究遇到的瓶颈，就职于中国中车轨道交通研究株洲所、主要负责智轨系统交通组织及策略研究与应用的外聘专家刘浏工程师以《智能轨道快运系统及其在株洲的应用》为题，从智轨快运系统研发背景、车身系统、走行系统、控制系统、网络系统、辅助系统、牵引系统、信号与通讯系统等方面，运用丰富、直观、精美的视频与图片，深入浅出地对智轨快运系统的核心技术的基本原理作了详细的介绍，使SSI-L项目组团队师生茅塞顿开，困扰已久的疑云豁然开朗。刘浏工程师还以智能轨道快运系统在株洲的应用，用详实的数据，展现了智轨的市场化历程，并对智轨未来在国际和国内城市化与都市圈的应用作出了前景展望。当刘工程师指出中国在西方欧美国家轨道交通技术垄断与打压的背景下，依靠中国中车几代科技工作者顽强拼搏精神，成长为世界上轨道交通最发达的国家，中车株洲所研发智轨列车是中国拥有自主知识产权的四列列车之一时，学子们民族自豪感和爱国情怀油然而生，会场爆发出热烈的掌声和欢呼声。
演讲结束后，九方中学SSI-L项目组教师研发团队负责人李永平博士代表项目组老师与刘工程师进行了有关智轨列车线路布局规划与城市规模关系等问题探讨，项目组学生团队也纷纷举手与专家互动，刘工程师一一详细地为学生们解答了议题中遇到困惑。当得知年轻的刘工程师是一位毕业于名校的“学神”时，会场立即涌现出一大批“粉丝”，纷纷要求专家分享高中时代的学习经验。刘工程师以晋代诗人陶渊明的名言：“勤学似春起之苗，不见其增，日有所长；辍学如磨刀之石，不见其损，日有所亏”，勉励学生们，积跬步而致千里，学好本领，回报家国。并在会后应部分表示将来有志于从事轨道交通相关工作同学要求，告知他们高考志愿填报应该选择哪些相关专业。
“让每一位师生都得到充分发展”一直是株洲市九方中学秉承的办学理念，SSI-L教学的开展，为学校师生学科核心素养的培育创设了一个极好的机遇和平台，促成了学生深度学习，促进了学生核心素养的发展和教师职业素养的提升。本次学术讲座学校十分重视，校党委书记、校长暨项目负责人陈捍东同志和部分骨干教师出席了会议，项目主管副校长李平军同志为刘浏工程师颁发了为期五年的九方中学SSI-L项目组外聘专家证书。

With snow melting and breeze from the south, spring is coming to the campus of Jiufang Middle School. On the evening of February 28, 2022, bursts of laughter came out of the academic lecture hall of Jiufang Middle School of Zhuzhou City. Teachers and students of the school’s SSI-L project team and some students of the 10th-grade Hongzhi class welcomed their long-awaited distinguished guest with the warmest applause, Liu Liu, an external expert of the school’s SSI-L project team and an engineer of China CRRC Railway Research Institute.
Under the Alliance of Improving Scientific Literacy (AISL), the SSI-L project is a science education cooperation project jointly initiated by the Collaborative Innovation Center of Assessment for Basic Education Quality at Beijing Normal University and the University of North Carolina at Chapel Hill. Since 2020, Jiufang Middle School, as one of the first batch of SSI-L project base schools has been actively promoting SSI-L teaching practice and exploration based on its own situations and learning conditions. Teachers and students from the project team have completed several SSI issue selections and investigations, including “Why is the prevalence of lung cancer increasing year by year?” “Should high-speed rail stations be located in urban areas or suburbs?” “Intelligent railway and urban traffic issues”. They have successfully concluded the first round of SSI-L teaching based on the work plan, and achieved the initial goal of two-way education of core disciplinary literacy and the cultivation of scientific emotional attitudes and values.
In the second round of the 10th-grade SSI-L teaching, the SSI issue selected by the teachers and students of the project team is “Intelligent railway and urban traffic issues”. In order to break through the bottleneck problems the team has on the motivating questions during SSI-L teaching, Liu Liu, an external expert who works in the Zhuzhou Institute of CRRC Railway Research Institute and is responsible for research and application of intelligent railway system and transportation organization strategy, gave a lecture titled “Intelligent Rail Rapid Transit System and the Application in Zhuzhou”. The lecture covers the research and development background of the Intelligent Rail Rapid Transit System, its body system, running system, control system, network system, auxiliary system, traction system, signal and communication system, and others. He presented a large number of visually illustrative videos and pictures and gave a detailed introduction to the basic principles of the system’s core technology. The lecture made the teachers and students of the SSI-L project team feel enlightened with some of the long-standing doubts being clarified. Liu also took the application of this intelligent system in Zhuzhou as an example, and showed the marketization process with detailed data, and his vision for the future application of the intelligent railway in urbanization and metropolitan circles, both domestically and internationally. When Liu pointed out, against the backdrop of transportation technology monopoly and suppression of western powers, particularly the US and European countries, China has grown into the most developed country in railway transportation around the world by relying on the tenacious working spirit of science and technology personnel of CRRC for multiple generations, and the intelligent railway developed by CRRC Zhuzhou is one of the four trains with independent Chinese intellectual property rights, students’ national pride and patriotism was spontaneously aroused and the venue burst into warm applause and cheers.
After the speech, on behalf of all teachers of the project team, Dr. Li Yongping, leader of the teachers’ research and development team of the school’s SSI-L project, discussed with Liu about the relationship between smart railway layout planning and the scale of cities. Student groups also raised questions and interacted with the external expert. Liu answered their questions in detail one by one. When they learned that the young engineer Liu was a “student icon” graduated from a famous university, lots of “fan” students emerged at the venue, asking him to share his learning experience in high school. Quoted Tao Yuanming, a famous poet of the Jin Dynasty, “To study diligently is like growing seedlings in spring. We cannot see how much they grow but they are growing day by day. To drop out is like a sharpening stone. We cannot see how much it abrades but it’s damaged day by day”, Liu encouraged students to take small steps every day and make progress in the long run, and to harness their skills and serve the motherland in return. In response to some of the students’ enquiries, he also said after the lecture that he would advise students who are interested in working in the railway transportation industry in the future on which majors to choose for the college entrance examination application.
It has always been the school’s education philosophy to make every teacher and student well developed.
SSI-L teaching offers great opportunities and platforms to promote students’ in-depth learning, the development of students’ core literacy and teachers’ professional quality. The school has attached great importance to this academic lecture. Chen Handong, secretary of the school party committee, principal and head of the school’s SSI-L project, and some key teachers attended the meeting. Li Pingjun, vice principal of the school and project director, granted Liu Liu a five-year external expert certificate of the school’s SSI-L project.
