万双网讯  5月31日，龙华区罗绵景名师工作室 “名师进民校”暨华南实验学校与万科双语学校初中数学联合教研活动在深圳市龙华区万科双语学校成功举办。本次活动的主题是基于初中数学单元整体教学的专题复习探讨，旨在深化初中数学复习教学改革，提升参与初中数学老师的专业素养，并促进公民办学校的一体化建设，开展结对帮扶活动。

VBS Net News   On May 31, the Luo Mianjing Famous Teacher Studio in Longhua District "Famous Teachers Entering Private Schools" and the joint teaching and research activity of junior high school Mathematics between South China Experimental School and Vanke Bilingual School were successfully held in Vanke Bilingual School.The theme of this event is a special review discussion based on the overall teaching of junior high school mathematics units. It aims to deepen the reform of junior high school mathematics review teaching, improve the professional quality of participating junior high school mathematics teachers, promote the integrated construction of public and private schools, and carry out pair assistance activities .

活动分为观课、议课和主题讲座三个环节。观课环节中，万科双语学校的刘欢老师和龙华区罗绵景名师工作室成员华南实验学校赵丽慧老师执教了《尺规作图与创新作图》课题。

The activity is divided into three parts: observation, discussion and lecture. During the class observation session, teacher Liu Huan from Vanke Bilingual School and teacher Zhao Lihui from South China Experimental School, a member of the Luo Mianjing Famous Teacher Studio in Longhua District, taught the topic of "Ruler-compass Drawing and Innovative Drawing".

刘欢老师先带领学生回顾基本尺规作图方法与依据，并完成基础性练习，再从学生相对熟悉的网格作图入手，分四个活动去探索仅用无刻度直尺作图的解决方法和思想，突破本节课的教学重点“创新作图”。使学生通过自主合作学习，分析图形的性质和基本原理，归纳推理作图依据，并应用于创新作图。让全部学生能用作图原理与方法进行推理、论证与应用。

Teacher Liu Huan first led the students to review the basic ruler and compass drawing methods and basis, and completed the basic exercises, and then started with the grid drawing that students are relatively familiar with, and divided them into four activities to explore the solution of only using a non-scale ruler for drawing and ideas, break through the teaching focus of this lesson "innovative drawing".Through independent and cooperative learning, students can analyze the nature and basic principles of graphics, inductively infer the basis of drawing, and apply it to innovative drawing. To enable all students to reason, demonstrate and apply graph principles and methods.

赵丽慧老师从尺规作图到创新作图，再回归到尺规作图，以图形的性质为线，既让学生完整经历作图过程，体会和运用了一些基本思想（如转化、特殊到一般），开阔了思维。又感受了作图方法的一致性，即想象-分析-生成-反思。以追问和问题串的方式引导学生进行探究，培养学生分析问题、解决问题、动手操作、逻辑推理的能力，发展学生的几何直观。

Teacher Zhao Lihui went from drawing with ruler and compass to innovative drawing, and then back to drawing with ruler and compass. Taking the nature of the figure as the line, she not only allowed students to fully experience the drawing process, but also experienced and applied some basic ideas (such as transformation, special to general ), broaden the mind.

随后进行了议课环节，上课的老师进行了说课，并得到了初中数学名师罗绵景老师、万科双语学校林红英校长助理以及听课老师们的评课和指导。

Afterwards, there was a lesson discussion session. The teachers in the class gave lectures, and got the evaluation and guidance from Mr. Luo Mianjing, a famous junior high school mathematics teacher, Lin Hongying, the assistant principal of Vanke Bilingual School, and the listening teachers.

评课老师一致认为，刘欢老师的课，重视点拨方法与技巧，有延展性；题型分类清晰、深度适合；教学语言简洁，能追问到根本。教师能真正做到关注每一位学生，并给学生充分的探索空间和展示机会。赵丽慧老师的课，由内而外散发魅力。她不断通过探究和追问，引导学生注重知识的根源，重视语言激励，提高学生学习积极性；教学内容由浅入深，板书设计逻辑性强；能够及时抓住学生的闪光点，总结提升。

The evaluation teachers agreed that Mr. Liu Huan's class focused on teaching methods and skills, and was extensible; the question types were clearly classified and suitable for the depth; the teaching language was concise and could go to the root of the question. Teacher can really pay attention to every student and give students sufficient exploration space and display opportunities.

Teacher Zhao Lihui's class exudes charm from the inside out. Through continuous exploration and questioning, she guides students to pay attention to the root of knowledge, pays attention to language motivation, and improves students' learning enthusiasm; the teaching content is from shallow to deep, and the design of blackboard writing is logical; she can grasp students' bright points in time and summarize and improve.

最后，龙华区卓越教师工作室主持人罗绵景老师进行了主题讲座，主题是《尺规作图，画出精彩》。

Finally, Mr. Luo Mianjing, the host of the Excellent Teacher Studio in Longhua District, gave a lecture on the theme of "Constructing with Rulers and Compasses, Drawing Wonderful".

罗绵景老师对比了三个版本课标对尺规作图的要求和2022年版尺规作图内容的分布变化，分析了当前尺规作图教学中的问题，带领大家体会尺规作图的教学价值，结合新课标颁布后的2022年中考试题分析了尺规作图试题的命题方向，强调了各地区中考试卷中对尺规作图专题的设计更加注重操作性、生成性和思想性，力求将尺规作图的“想法、作法和道理”融为一体，进一步落实新课程标准的理念。最后提出了尺规作图教学的思路、启发和要求。

Teacher Luo Mianjing compared the requirements of the three versions of the curriculum standards for drawing with rulers and compasses and the distribution changes of the content of drawing with rulers and compasses in the 2022 edition, analyzed the current problems in the teaching of drawing with rulers and compasses, and led everyone to experience the teaching value of drawing with rulers and compasses, combined with the 2022 high school entrance exam questions after the promulgation of the new curriculum standard, analyzed the proposition direction of the ruler and compasses drawing test questions, and emphasized that the design of the ruler and compasses drawing topic in the mid-term exam papers in each region pays more attention to operability, generation and thinking, and strive to integrate the "ideas, methods and principles" of ruler and compass construction into one, and further implement the concept of new curriculum standards. Finally, the train of thought, inspiration and requirements for the teaching of drawing with ruler and compass are put forward.

本次活动吸引了万科双语学校、华南实验学校全体数学教师以及龙华区罗绵景名师工作室部分成员参会。参会人员积极参与讨论，分享了各自的教学经验和观点。活动期间，所有参与者积极认真学习交流，保持了良好的学习氛围。

This event attracted all mathematics teachers from Vanke Bilingual School, South China Experimental School, and some members of Luo Mianjing Famous Teacher Studio in Longhua District. Participants actively participated in the discussion and shared their teaching experience and views. During the event, all participants actively and conscientiously studied and communicated, maintaining a good learning atmosphere.

通过本次活动，教师们获得了宝贵的教学经验和启发，对基于初中数学单元整体实践的复习教学有了更深入的理解。活动的议课环节尤为重要，通过评课和指导，教师们得到了名师的意见和建议，进一步提高了教学水平。
