Can Student-Collected Data Help Teachers?

In the article "Student-Driven Research" in this month's Educational Leadership, authors Makeba Jones and Susan Yonezawa discuss a program in San Diego where students are part of co-research teams that collect data from interviews and surveys of their peers and teachers to offer insight on how to improve curriculum and education practices.

"Students have unique expertise regarding schools," the authors say."[The students] can provide important information about school and classroom practices and policies."

What keeps more schools from drawing on students' experiences as a way to improve public education?
