At the beginning of the semester, all teachers (including administrative staff) participated in internal open class demonstrations one after another. In May, with a light rain passing by, leaves became vibrant green. On the 15th and 16th, representatives from each subject group were selected to refine their best works and showcase 11 school-level open classes. The school invited experts to serve as judges: Vice Principal Hu Shaoming, Director Zhou Xiang, both at the senior level, and Mr. Li Gongliang, the Teaching Director of Jin'an Group.
MATHEMATICAL AND SCIENTIFIC PROJECT
Teacher Zhang Jianyin's open class on the "Möbius Strip" was like a fascinating feast of science and mathematics, truly commendable!
In terms of classroom organization, Teacher Zhang demonstrated outstanding control. The entire classroom was orderly, and Teacher Zhang guided the students step by step into the wonderful world of the Möbius Strip. Each segment was closely connected with natural and smooth transitions, keeping the students highly focused and engaged throughout.
The teaching activities were diverse and highly creative. Through lively demonstrations, interesting experiments, and interactive discussions, Teacher Zhang allowed the students to touch and feel the unique properties of the Möbius Strip firsthand. The students actively engaged in hands-on activities, observed phenomena, and deeply understood the mysteries of the Möbius Strip through practice, with sparks of thinking constantly bursting in the classroom.
From the perspective of teaching effectiveness, it was beyond imagination. The students not only gained a clear and profound understanding of the Möbius Strip but also ignited a strong interest in exploring mathematics. Everyone in the classroom marveled at the wonders of mathematics, as if a door to the unknown had been opened, fueling a desire and enthusiasm for knowledge that was delightful to see. Teacher Zhang's professionalism was admirable; she had a thorough understanding of the Möbius Strip, explained it in simple terms, making complex concepts understandable to the students. Her passion and enthusiasm infected every student, making the classroom vibrant and lively. Her patience and attention to detail also made the students feel extremely at ease during the learning process, allowing them to explore and discover freely.
This Möbius Strip open class was a brilliant performance by Teacher Zhang and a memorable learning journey for the students. I believe that under Teacher Zhang's guidance, the students will continue to explore the wonders and excitement of mathematics, going further and further on the path of mathematics exploration!
Teacher Xu Ruliang gave a lesson on "Feeling Possibilities," using examples from daily life such as weather forecasts, sunrise, dates, playing cards, and lottery tickets to illustrate the magnitude of events' possibilities and distinguish between event categories. Through various examples, students quickly grasped the concept of event classification. Next, the teacher asked students to give examples, and they eagerly shared various examples. For instance, one student said, "The teacher assigning homework on weekends is a certain event," sparking a lively discussion and laughter.
Chinese and mathematics are closely related. Teacher Xu listed many idioms and asked students to identify the events they represent. For example: "Catching turtles in a jar," "Pulling up seedlings to help them grow," "Waiting by a tree stump for rabbits," and so on. This opened the students' knowledge gate and led to a lively game of idiom chain, leaving a lasting impression amidst laughter.
The incorporation of games into the mathematics classroom was a major highlight of this lesson. Learning through games, students used their knowledge to play games. They took turns in groups to come to the front of the class and categorize falling blocks based on the events they represent, testing their reaction speed and examining their understanding of the concepts learned.
Teacher He Jiayi's class is distinctive, featuring three inquiry sessions where students complete learning tasks through activities with outstanding results.
Inquiry One: Through self-learning and group cooperation, students become familiar with the names and functions of each part of the prints and models. Representatives from each group assemble the scattered models. Teacher He Jiayi used digital resources such as pictures, animations, and models to improve the presentation of teaching content, optimize the teaching process, enhance teaching intuitiveness, vividness, and richness.
Inquiry Two: Formation of vision. After demonstrating with small flashlights, students have a preliminary understanding of the structures through which light reaches the retina, supplementing the light's path in the guided case. At the same time, Teacher He Jiayi posed a question: What if a person's eyes are intact but they cannot see anything? This question stimulates student thinking about the conditions necessary for seeing things.
Inquiry Three: Myopia and its prevention. Using videos, the process of lens changes prompts student thinking about the relationship between myopia and lens changes. They identify the causes of myopia and discuss how to prevent myopia in daily life through group discussions.
The biology classroom combines education with entertainment, primarily aiming to promote students' transformation from passive to active learning, shifting from "I have to study" to "I want to study," integrating biological knowledge into everyday life to gradually improve students' subject literacy.
Three teachers were evaluated by Director Zhou Xiang, the curriculum supervisor, during the presentation class of the third session of the math and science project-based learning. They were praised for their skillful use of teaching methods, empowering students' role as active participants, and for integrating knowledge into logical frameworks while blending contextual situations with the knowledge. Director Zhou also inspired the teachers with his own lesson design: structuring problem designs in a structured manner and serializing scenario designs.
