In a Martin Elementary School classroom, teacher Carol Johnson rarely finds the need to stand in front of her fourth-graders and lecture on a literacy lesson.

At Marengo High School, science teacher Terie Engelbrecht doesn’t need to remind her underclassmen to write notes on a lab assignment. Laptop computers replaced stodgy paper notebooks a few years ago.

The teachers are from different school districts but have firsthand experience with the digital transformation that is changing classrooms in McHenry County and the country.
