The per capita area of the playground is less than 1.5 square meters, which was once a "sports challenge" for more than 900 teachers and students at Yuxin Primary School in Jinan City, Shandong Province. Nowadays, through the reform of "staggered large breaks" and the full utilization of interactive "small venues", Yuxin Primary School has turned "small troubles" into "big highlights". At 2:45 pm and 3:35 pm, with the sound of the broadcast prompt, a 40 minute long break was held on the playground of Yuxin Primary School, with 6 grades staggered. There are two grades in the front yard and one grade in the middle yard. Physical education classes are arranged normally in the backyard, and each area does not interfere with each other. To improve the effectiveness of exercise, the school has integrated martial arts exercises, long-distance running, accelerated running, myopia prevention exercises, etc. into the break time, with effective activity time accounting for 70%. In 2024, the overall physical fitness rate of students in the school will increase by 12% year-on-year, while the myopia rate will decrease by 3.2%. Wrong timing is not just about dividing time, but also about taking responsibility and improving efficiency. ”Shen Shun, the principal of Yuxin Primary School, has over 20 versions of his schedule stored on his phone; On the ground of the campus front yard, location markers are repeatedly drawn, and these details witness the level of refinement of the reform. In Jinan, many schools in old urban areas are limited by factors such as venues, which restricts the physical exercise space for teachers and students. We require schools to adapt to local conditions and implement the action of strengthening students' physical fitness step by step, "said Zhang Lihua, director of the Sports, Health and Arts Department of Jinan Education Bureau. Faced with the serious shortage of campus activity space in the old city area, Zhang Shuo, a physical education teacher at Zhijin Street Primary School in Jinan, led a team to start the practice of "asking for venues from the sky". They marked the wall height with chalk, created a climbing and height training area, built a stepped climbing frame with waste gymnastics mats, transformed plastic bottles into "sand bottle dumbbells", and set up a folding hurdle obstacle track in a corner of the campus. Under such careful design, the participation rate of students in sports activities has increased by 20% to 40%, the average sitting and forward bending score has improved by 4 centimeters, the sit up pass rate has increased by 35%, and the overall myopia rate has decreased by 5%. This kind of "seizing every opportunity" innovation is being replicated and promoted in schools in the old urban areas of Jinan. From the 333 square meter "Cloud Sports Space" on the rooftop platform of Baotu Spring Primary School, to the development of many indoor corridors and classrooms as "micro sports areas" in schools, each school has created sufficient sports space for students and improved their physical literacy. Data shows that in 2024, the obesity rate of Jinan students' physical fitness and health will decrease by 8% year-on-year, and the myopia rate will achieve a "four-year continuous decline". The "staggered use and collaborative governance" not only provides students with a larger activity space, but also solves the problem of tight public space resources. This year, next to the cement ground that was once jokingly referred to as the "patch field", the Public Utility Development Center of Jiyang District Second Experimental Primary School has upgraded and transformed a 750 square meter idle land outside the school wall into a multi-functional fitness venue, which is open to surrounding residents while benefiting the school. We will always anchor 'health first' and innovate through multiple paths such as policy guidance, spatiotemporal reconstruction, curriculum reform, teacher optimization, AI empowerment, etc., so that the limited space of each school can be transformed into an energy field for the physical leap of young people. ”Wang Hong, Secretary of the Party Group and Director of the Education Bureau of Jinan City, stated.
