Zhejiang Primary School’s “Smart Playground” collects student movement data through millimeter wave radar
Recently, many primary schools in Zhejiang Province have introduced a "smart playground" system to collect student movement data in real time through millimeter wave radar technology, which has attracted widespread attention from the education and technology circles. This innovative measure not only improves the accuracy of physical education teaching, but also provides a scientific basis for students' physical health management.
1. Technical principles and implementation background
The "Smart Playground" system uses millimeter-wave radar technology, which can monitor key indicators such as speed, distance, heart rate during students' movement without contact. Compared with traditional wearable devices, this technology avoids the problem of equipment loss or damage, while ensuring the continuity and accuracy of data. The Zhejiang Provincial Department of Education stated that this move is to respond to the national "double reduction" policy and optimize the allocation of physical education resources through scientific and technological means.
2. Core data performance
The following are some data statistics collected by the pilot schools within one week:
| index | average value | Maximum value | Minimum value |
|---|---|---|---|
| 50m running speed (m/s) | 5.2 | 6.8 | 4.1 |
| Number of skipping ropes (times/minute) | 102 | 156 | 68 |
| Exercise heart rate (bpm) | 128 | 182 | 95 |
| Daily exercise duration (minutes) | 45 | 78 | twenty two |
3. Social response and expert opinions
After the system is launched, it received feedback from multiple parties:
| group | Support rate | Key opinions |
|---|---|---|
| Parents | 87% | Recognize data-based health management |
| teacher | 92% | The targeted teaching is significantly improved |
| student | 76% | Like the experience of technology |
Professor Li from the Institute of Educational Technology, Zhejiang University pointed out: "The application of millimeter-wave radar breaks through the observation limitations of traditional physical education teaching, but attention should be paid to the ethical boundaries of data use to avoid the pressure brought by excessive quantification."
4. Future development plan
Zhejiang Province plans to promote projects in three stages:
| stage | Time node | Target |
|---|---|---|
| Pilot period | 2023Q4 | Covering 20 key primary schools |
| Promotion period | 2024 | Expand to 200 schools |
| Deepening period | Starting from 2025 | Establish a provincial sports database |
5. Controversy and Thoughts
While gaining praise, the technology also faces doubts about privacy protection. Some parents are concerned about the safety of the storage and use of sports data. In response, the project leader responded: "All data has been desensitized and is only used for teaching improvement and scientific research, and is stored on the education dedicated network server."
Education experts suggest that in the process of promoting smart sports, a tripartite supervision mechanism should be established, including a data management committee with the participation of schools, parents and technology suppliers, to ensure the balance between technological innovation and humanistic care.
With the promotion and application of "smart playground", this model that deeply integrates cutting-edge science and technology with basic education may become an important direction for physical education reform in the new era. The subsequent development deserves continuous attention.
