Jack Silva didn't know anything about how children learn to read. What he did know is that a lot of students in his district were struggling.
Silva is the chief academic officer for Bethlehem, Pa., public schools. In 2015, only 56 percent of third-graders were scoring proficient on the state reading test. That year, he set out to do something about that.
"It was really looking yourself in the mirror and saying, 'Which 4 in 10 students don't deserve to learn to read?' " he recalls.
