. pearl guard tower is located in Tianma Mountain Park, Sheshan National Forest Park, Shanghai. . Due to the changes in the foundation over the past thousand years, the tower body has gradually tilted to the southeast. Because its slope exceeds the famous Leaning Tower of Pisa in Italy, it is known as the "Leaning Tower of Pisa in Shanghai". Why does the Leaning Tower of Millennium not fall down? How to protect this leaning tower and better convey its historical and cultural value? Recently, a unique study class was launched under the Bead Protection Tower.
There are no textbooks, no desks and chairs, the classroom is set in nature, and the air is filled with the fragrance of osmanthus, which makes the students participating in the study and study in Tianmashan School very excited. The teacher on the day was from Songjiang No. 1 Middle School. After receiving the study and study task list, everyone quickly divided the group and conducted on-site surveys on the geographical environment, tower body appearance, tower body structure and building materials of the bead protection tower.
When discussing how to measure the height of the tower, Zhou Gang, a mathematics teacher at Songjiang No. 1 Middle School, did not intervene too much at the beginning, but left enough time and space for students to discuss freely. After trying again and again, under the guidance of Zhou Gang, the students tried to use tape measure, angle measuring instrument and other tools to solve the problem of tower body height measurement through methods such as estimation of bricks and three-dimensional geometric thinking. "If you teach everyone the methods directly, it lacks the process of exploring and thinking, and the purpose of project-based learning cannot be achieved." Zhou Gang said that the process of independent problem solving not only trains students' thinking, but also cultivates their sense of teamwork. After the in-class investigation, the teachers also prepared for students such as the examination of the construction of the pearl guard tower, the reason for the inclination of the leaning tower, and the investigation of the current status of the leaning tower protection. This greatly stimulated everyone's desire for exploration and knowledge. Sheng Zihan, a student of Class 8 (2) of Tianmashan School, said: "Learning while learning and playing while learning is much more fun than learning in the classroom, and there is also a lot of motivation to think."
"Leading students to carry out real exploration and research based on real problems, and finally obtain real research results. This process is very meaningful for teachers and students." Shan Huilu, a physics teacher at Songjiang No. 1 Middle School, introduced that as an interdisciplinary research course, the exploration of the Millennium Leaning Tower covers a wide range of fields and is highly exploratory. In fact, as early as a year ago, Songjiang No. 1 Middle School joined hands with Tianma Mountain Park in Shanghai Sheshan National Forest Park, and carried out preliminary exploration and practice around the topic of "Why does the thousand-year-old leaning tower tilt but not falling?" Recently, Tianma Mountain Garden was included in the first batch of study and travel bases in Songjiang . In the future, the study and study project will be expected to be promoted throughout the region.
