方山小雨润如酥，草色遥看近却无。在春日的一场小雨中，3月19日，江宁区初中物理教学研讨活动在南京外国语学校方山分校科技高中阶梯教室举行。江宁区物理教研员赵帅等领导以及江宁区各学校老师们前来参加，本次活动共设三节观摩课以及交流研讨活动。
On March 19th, with the moist rain over the fresh grass in Fangshan, the Jiangning District Junior High School Physics Teaching Seminar was held in the high school lecture hall of NFLSFC. Leaders such as Zhao Shuai, a physics teacher and researcher in Jiangning District, as well as teachers from schools in Jiangning District, came to participate. There were three observation classes and exchange seminars for this activity.
第一节课是南外方山分校八年级物理组张建峰老师执教的《重力 力的示意图》。张老师以沙子的下滑和地球仪巧妙引入课堂，夺人眼球。随着课堂深入，学生的物理兴趣与课堂热情渐进上升，张建峰老师言语温婉思路严谨，利用学生的好奇引发思考，循循善诱，将重力方向、重力的影响因素等重难点知识融入设问、融入实验。整节课围绕课本，基于实验，通过学生分组实验极大发挥了学生的主观能动性，将寻找扫把重心的实验作为课堂的高潮，彰显了南外方山分校教师扎实的教学功底和学生出色的动手能力。
The first class is "Schematic Diagram of Gravity" taught by Mr. Zhang Jianfeng, the eighth grade physics group of NFLSFC. Mr. Zhang used the sliding of sand and the globe to cleverly introduce the classroom, which caught the eyes of students. As the classroom deepens, students’ interest in physics and enthusiasm in the classroom gradually rise. Zhang Jianfeng’s words are gentle and rigorous. He uses students’ curiosity to trigger thinking and integrates important and difficult knowledge such as the direction of gravity and the influencing factors of gravity into the questioning and experimentation with good guidance. The whole class revolved around textbooks and experiments, and the students’ subjective initiative has been exerted greatly through group experiments. The experiment of finding the focus of the broom is the climax of the classroom, demonstrating the solid teaching skills of the teachers of NFLSFC and the outstanding experiment ability of the students.
第二节课是南京晓庄师范学院滨河实验学校的刘莹老师执教的《摩擦力》。课堂刚开始刘老师就组织学生参与小游戏“夹鹌鹑蛋”，轻松的音乐搭配趣味的游戏一下子就拉近了老师与同学们的距离，借此开启了摩擦力的课堂。本节课的重点是滑动摩擦力的研究，课堂上同学们全神贯注，积极发言，遇到问题大胆猜想，通过分组实验和交流逐步验证猜想，记录数据。刘老师语言凝练，十分注意理解性知识之间的衔接，在师生互动、生生互动中，一堂课的时间转瞬即逝，但同学们却意犹未尽。
The second class is "Friction" taught by Liu Ying from the Binhe Experimental School of Nanjing Xiaozhuang Normal University. At the beginning of the class, Mr. Liu organized students to participate in the mini game "Quail Egg". The relaxed music and fun games immediately brought the teacher and classmates closer together, thus opening a frictional classroom. The focus of this lesson is the study of sliding friction. In the class, the students are fully absorbed, actively speaking, making bold guesses when encountering problems, and gradually verifying the guesses through group experiments and communication, and recording data. Mrs. Liu is condensed in language and pays great attention to the connection between comprehensive knowledge. In the interaction between teachers and students, the time of a class is fleeting, but the students are still feeling unfulfilled.
第三节课是由南外方山分校九年级物理组陆媛媛老师讲授的《物质的物理属性》复习课，课堂以密度的定义、公式、单位及密度测量步骤为轴，有如打开一幅长篇画卷，将密度相关的实验和中考考点分步展开，逐层递进。课堂主要设计两大复习环节：测量小石块密度，测量大石块密度，通过图片、实验的重现唤醒孩子们对于已学知识的认知。陆老师着重关注学生的思维活跃性、课堂参与性，辅以等效替代法等关键难点的讲解，将复杂的密度板块拆分，一堂中考物理复习课教师讲授出了南外方山分校的特色，学生更是演绎出了别样的精彩。
The third class is a review class of "Physical Properties of Matter" taught by Lu Yuanyuan, the ninth grade physics teacher of NFLSFC. The class took the definition, formula, unit and density measurement steps as the axis, which is like opening a long picture scroll, expanding the related experiments and the test sites of the senior high school entrance examination step by step. The class mainly designed two review sessions: measuring the density of small rocks, and measuring the density of big rocks to wake children's knowledge of what they have learned through the reproduction of pictures and experiments. Mrs. Lu focused on students’ thinking activity and classroom participation with explanations of key difficulties such as equivalent substitution method, and complex density blocks were split for better understanding. A class of high school entrance examination physics review class gives the characteristics of NFLSFC, and students performed a different kind of excitement.
评课环节，几位老师发言踊跃，大胆探讨，对于备课和课堂环节进行了总结与交流。评课名师们对上课教师的精彩课堂给以了充分的肯定，提出了许多有深度、有价值的建议。最后，江宁区初中物理教研员赵帅老师对本次活动做了总结：第一，板书是课堂的灵魂，是学生对于一节课印象最深的记忆，每节课都需要设计好精炼、有取舍的板书；第二，加强整节课的模型建构，课堂的深度很关键；第三，就是要在中考物理复习课中，着眼于撼动学生的固化思维，实验与题型都要推陈出新、咬文嚼字，将复习落实到学生认知深处。在这样的研讨、指导氛围中，所有到场的老师都收获良多，对物理学科教学起了巨大的促进作用。
In the evaluation session, several teachers spoke and discussed enthusiastically, summing up and communicating about the lesson preparation and classroom links. The professional teachers gave full affirmation to the wonderful class of the teachers and put forward many in-depth and valuable suggestions. Finally, Mr. Zhao Shuai, a junior high school physics teaching and researcher in Jiangning District, summarized this activity: First, writing on the blackboard is the soul of the classroom, and is the student’s deepest memory of a lesson. Each lesson needs to be designed and refined. Second, to strengthen the model construction of the entire class, the depth of the class is very important; third, it is necessary to focus on shaking the students’ solidified thinking in the physics review class of the high school entrance examination. Experiments and question types must be updated and written, and implement review to students' deep cognition. In such an atmosphere of discussion and guidance, all the teachers present have gained a lot, which has greatly promoted the teaching of physics.
