Answer:
expectation theory.
Step-by-step explanation:
Teachers often expect less from students of certain racial, ethnic, and cultural backgrounds. When teachers expect students to perform poorly, they approach teaching in ways that align with their low levels of expectations. Students tend to respond to this expectation by their teachers, by performing at the low levels .
This theory was tested in 1968 by Rosenthal and Jacobson in their Pygmalion Effect study. A group of teachers were told that their students were due for an intellectual growth spurt during the school year. Even though the students were average in terms of academic performance, the teachers interacted with them based on this expectation.
All students in the experimental group improved both academically and socially by the end of the year. Based on the notion of a self-fulfilling prophecy, students who experience high expectations seek to reach the level of expected behaviors. Correspondingly, students who experience low expectations act to meet the level of behavior expected of them.
This attitudes is what Marie's colleagues are manifesting.
