Internet Nonconnectivity Impact study

From the benefits of teaching lifelong digital citizenship skills to the challenges of preparing students to critically evaluate online information, educators across the country share their perspectives on what it's like to teach in today's fast-changing digital world. Nevertheless, about 12% of teachers said that more than 60% of students lack the home internet connectivity needed to complete their homework, according to a recent report.  In response, about 42% of teachers at high-poverty schools said they avoid assigning homework that would require an internet connection.
