Parents in Xi'an suggested that schools cancel electronic screen classes

Official: Do not use unless necessary

Recently, some netizens suggested for the mayor of Xi'an, suggesting that schools cancel the use of electronic screens for classes. The message said that the teaching electronic screens used in many schools in Xi'an make the students' eye fatigue common, and the high proportion of myopia in primary and secondary schools is also due to this reason, so it is recommended that schools cancel the use of electronic screens.

In response to this suggestion, the People's Government of Weiyang District of Xi'an City made a detailed response and proposed measures to implement the "five management". It is mentioned that the school has taken corresponding measures to protect students' eyesight: in classroom teaching, do not use electronic screens unless necessary, and when they must be used, the electronic screens should not be turned on for more than 10 minutes in a single class to ensure that students' eyes have enough rest intervals.

Expert: Electronic screens should not be eliminated altogether

In this regard, a media reporter interviewed Dr. Wang, deputy chief physician of the Department of Optometry of the Eye Hospital of the China Academy of Chinese Medical Sciences. Dr. Wang said that the use of electronic screens should not be completely abolished, and the use should be reasonably standardized.

Dr. Wang said that whether the electronic screen affects vision is determined by a number of factors, and the difference in parameters of different electronic screens has different effects on visual acuity, and the different setting distances and the length of a single use of the electronic screen will also have different effects. In general, it is not recommended for children to keep staring at the screen for more than 15 minutes.

各地多所學校推行“無屏課堂”

It was found that, in fact, complaints and complaints about electronic screens have existed for a long time. Last year, some parents in Shenzhen left a message, suggesting that primary school students reduce the use of electronic screen time in classroom teaching; A video of a "post-80" parent holding a microphone at a parent-teacher meeting calling for "can the school replace the electronic screen blackboard with the previous normal blackboard" has also gone viral in the parent group.

Some schools have started to implement "screenless classrooms". According to media reports, starting from this semester, Jianghui Primary School in Hangzhou, Zhejiang Province will set Friday morning as a "vegetarian day" - all classes will stop using electronic screens, and teachers cannot use PPT and other courseware.

There are still many schools that choose to "screen closed", and the ways and means are different. A primary school in Quzhou, Zhejiang Province, gives the choice to the classroom teachers, who can randomly choose one day a week as a "vegetarian day"; A primary school in Wuhan, Hubei Province implanted "time-limited software" in the background of the all-in-one electronic screen in the classroom, and the electronic screen will be automatically turned off after the teacher has used it for 26 minutes in each lesson, and the screen can not be turned on again until the end of the lesson; A primary school in Nanjing, Jiangsu Province, set the 0th, 0th, and 0th of each month as the "Classroom No Electronic Screen Day", and all teachers turned off the big screen during class on that day.

4.0% of netizens think

"E-screen teaching should not be abolished altogether"

A poll with 14 participants called "Should schools cancel electronic screen teaching" showed that 0.0% of netizens believed that "electronic screen teaching should not be completely canceled, and it should be combined with the reasonable use of blackboards", 0.0% of netizens believed that "classes with electronic screens should be canceled and blackboards should be returned", and 0% of netizens chose "multimedia means to improve the teaching effect, and it is difficult to move an inch in a classroom without electronic screens".

Electronic screens are not a "panacea answer"

As an auxiliary tool for modern teaching, multimedia devices such as electronic screens can break through the limitations of traditional classrooms and improve teaching efficiency and experience. However, many parents are worried that their children's staring at the screen for a long time will affect their eyesight. In the face of concerns, the People's Government of Weiyang District of Xi'an City proposed measures to implement the "five management", strictly control the use time of electronic screens, strengthen the supervision and guidance of students' eye hygiene, and provide a pragmatic solution to the dispute.

It is important to note that teachers should not regard electronic screens as "one-size-fits-all" in the teaching process. When the whole courseware is played instead of the board book derivation, and the video display is used to replace the interaction between teachers and students, the electronic screen will be alienated from the "assistant" to the "protagonist". In daily teaching, the electronic screen should return to the role of "assistant" and scientifically plan the use boundary, so as to better achieve the dual goals of teaching innovation and health protection. In addition, in order to more effectively protect students' eyesight, schools must also pay attention to the optimization and maintenance of equipment, such as promoting low-blue-light, flicker-free eye protection screens, etc., to reduce health damage from the hardware side; Parents also need to control the time students spend on electronic devices after school, and work with schools to form a "protective chain" for eye health.
