At 9:05 A.M.,the bell rings and children file into their third-grade classroom.The first student to sit at his or her desk-book open and pencil ready to write-wins a star for the day.The students love this little bit of competition.This example of nonacademic socialization (which can teach students the benefit of competition) is referred to,by sociologists,as the:

A) silent curriculum.
B) hidden curriculum.
C) master curriculum.
D) invisible curriculum.
