[quote=capella]What worries parents most is that prolonged use of electronic products in online online classes https://ca.liuxuesavior.com/wang-ke-dai-xiu may cause the child's eyesight to decline. Baidu search big data shows that in the past 90 days, the search volume for "eye exercises + eye protection + prevention of myopia" increased by 247% year-on-year, and the search volume reached the highest level in a decade. Post-80s mothers are the main force searching for these keywords, and are heartbroken for their children's eyesight. Xiong Bingqi, vice-president of the 21st Century Education Research Institute: In some places, offline courses are directly moved to the Internet, and students study from morning to night, or at least in the afternoon. In this case, it may affect the development of students' vision. Since many online courses are recorded or non-video conferences, it is difficult for teachers and students to interact. Some parents are still worried. In online classrooms, students may send messages while they are in class, distracting them and affecting the effectiveness of the class, while some students do not attend class at all.[/quote]
