A first-of-its-kind lawsuit against three influential reading professors and their controversial literacy curricula has been dismissed, after a U.S. District Court declined to wade into the murky landscape of curriculum quality and education research. Last year, a group of parents filed the lawsuit, which alleged that the professors and their publishers used “deceptive and fraudulent marketing” to sell their popular reading materials. The case, brought by two parents from separate families in Massachusetts, centers on two sets of reading programs, one created by Lucy Calkins, an education professor at Teachers College, Columbia University, and the other by reading researchers Irene Fountas and Gay Su Pinnell, of Lesley University and The Ohio State University, respectively.
