Question
Characteristics of students may influence how favorably they are perceived by their teachers. One study examined whether teachers' perceptions of students may be influenced by the student's gender and socioeconomic status (SES) (Auwarter & Aruguete, 2008). They had a sample of teachers read a passage about a troubled student; in these passages, the researcher varied the student's gender and SES. After reading the passage, the teacher rated the student on his or her personal characteristics on a I to 5 scale; the higher the rating, the more positively the teacher viewed the student. The researchers hypothesized that male students would be rated more highly if they were of upper rather than lower SES, but the reverse was true for female students.
