IOWA CITY — While Kevyn Doningueiz, 11, a sixth-grader at Mark Twain Elementary, focuses on his virtual learning, his younger siblings get help from volunteers who can teach them how to use the computer and access online classes — thanks to Neighborhood NESTS. The Neighborhood NESTS — Nurturing Every Student Together Safely — is organized and operated by local not-for-profit groups for students in the Iowa City Community School District to access free Wi-Fi and get technical and academic support from volunteers, and for families to receive some child care services.
