Dulangkou Middle School. The removal of the podium began in 2003. In order to give full play to the dominant position of students and let students become the masters of the classroom, let students discover the rules themselves, let students summarize methods, let students explore ideas by themselves, and let students solve problems, the podium was removed. Remove the lectern. Teachers become guides, planners, participants, questioners, and collaborators; students become explorers, researchers, experiencers, expressers, creators, and achievers. The group desk arrangement cancels the arrangement of rice-planting desks, and becomes a group unit that sits across the desk and learns cooperatively. Students are strong, weak, and weak, teachers and students, and groups question each other. Explore, understand each other, accept each other, complement each other, and collide with each other to achieve the contention of a hundred schools of thought, the promotion of inspiration, and a win-win situation. Teachers absorb students’ opinions and ideas to improve their professional knowledge. Eugenics adds fresh blood by competing with opponents and "experiencing tricks". By helping weak students, they can better grasp the essential laws of things, and their methods and skills are further consolidated and expanded. Through the help of the top students, the confusion of the weak students becomes clear, and the doubts become concrete and real. Especially through many levels of three-dimensional contact, the self-esteem of the top students, the self-reliance of the average students, and the self-confidence of the weak students are realized. It can be said that everyone is happy to cooperate* **win. Multiple Blackboards There are many blackboards in each classroom of Dulangkou Middle School: front blackboard, back blackboard, north blackboard, and corridor blackboard. Some visitors said that it is time to apply for the Guinness World Records. The blackboard is a platform for students to express their learning results with pens. It is a position for establishing self-feedback and knowledge training and consolidation. It is a sacred board that generates self-confidence and enhances learning ability. In the words of Wang Jizhong, the former director of the Shandong Provincial Institute of Educational Sciences: The "four-sided blackboard" inside and outside the classroom cannot be equated with students' exercise books. It has three functions. First, through the display on the blackboard, students can basically After completing the homework, teachers and students corrected each other, achieving timely feedback on learning and timely strengthening and consolidation of knowledge; secondly, students wrote what they saw, thought, and thought on the blackboard, which played a role in mutual interaction among classmates. The role of communication thus broadens students' knowledge of each other; third, it provides students with an opportunity to practice writing. By writing on the blackboard, students' hard-pen calligraphy skills are improved, effectively solving the common concern that students in the computer age cannot write Chinese characters.
