Gorski warns that the nature of American classism oftencauses well-intentioned teachers to stereotype poor students. In “Accuracy and Inaccuracy inTeachers’ Perceptions of Young Children’s Cognitive Abilities,” Columbia University professorsDouglas D. Ready and David L. Wright explain their study of teacher biases, which indicatedthat “students’ skills come to reflect teachers’ initial perceptions” (356).
I believe the author could've done better here in eliminating the amount of background information on the source in an effort to get to the point. A possible option would've been to state "A study done by Columbia University indicated ... about the accuracy and inaccuracy of teachers' perceptions of young children cognitive abilities." Then proceed with the commentary or further source evidence if needed.
