“School tech has expanded rapidly, fueled partly by the Covid-19 pandemic. Federal aid during the pandemic let districts buy laptops and tablets, and a multibilliondollar ed-tech industry promised to transform teaching and help students recover lost ground.
Proponents said it can elevate instruction, narrow the digital divide, help pupils with language barriers and other needs—while often supplementing, not replacing, core curriculum. Educators have mixed views. In a recent EdWeek Research Center survey, more than half said the tech had a positive impact on engagement, yet a majority also said it negatively affected students’ well-being.
据教育软件公司Lightspeed Systems的数据显示，上学年，一至十二年级的学生平均每天使用学校配发的设备52分钟。这一数字有所下降，该公司认为这是由于部分学校采取措施限制科技产品的使用。.
Middle-schoolers spent about 70 minutes daily on screens in school during the past school year, more than elementary- and high-schoolers.”
