　　The impact of smartphones on students' attention

　　In its report, UNESCO pointed out that children may take up to 20 minutes to refocus after being distracted by smartphones.Wifi jammer This phenomenon is particularly prominent in the classroom. When students use their mobile phones frequently, their learning effects may drop significantly. In addition, studies have shown that over-reliance on smartphones may cause students to show lower patience and persistence when facing complex tasks.

　　In this context, smartphones are not just tools that interfere with learning, but may also have a profound impact on students' long-term attention and cognitive abilities. This situation is particularly evident in adolescents, because their brains are still in the development stage, and excessive screen time may have adverse effects on their cognitive development. Therefore, banning primary and secondary school students from using smartphones can help them better concentrate on learning and reduce the negative impact of external interference on their learning.

　　The role and limitations of technology in education

　　Although digital technology plays an increasingly important role in education, UNESCO points out that the extent of its application varies by region and socioeconomic conditions. In some developed countries, students are already accustomed to using digital devices in class, but in many developing countries, such technology application is still very limited.

　　In addition, UNESCO reminds us that over-reliance on technology may lead to increased educational inequality. Due to lack of resources, some countries find it difficult to provide equal technological resources to all students. This has led to a widening digital divide, which puts students who do not have access to digital devices at a disadvantage in education. Therefore, UNESCO recommends that countries should pay more attention to fairness when using educational technology to ensure that every student can benefit from technological progress rather than be excluded from it.
