Marie is a middle-grades teacher in a large city. Marie believes that all children can learn, and she strives mightily to help her students achieve. Yet, every day in the teacher's workroom she seems to get into arguments with colleagues who feel that it is a waste of time and effort to try to work with the students they teach, since "they're just going to wind up dropping out and going to jail." The attitudes of Marie's colleagues are indicative of A. deficit theory. B.expectation theory. C. cultural exceptionalism. D. cultural difference theory.

B. Expectation theory

Explanation:

The expectation theory is the belief that students performances are affected by the teacher's expectations from each child.

The experiment is to find out what would happen if teachers were told that certain kids in their class were destined to succeed.

The first psychologist to study this was Robert Rosenthal, a Harvard professor, who experimented at an elementary school in 1964.

expectation theory.

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.

the correct answer is ) possibility.

demonstrating opportunity cost is done through production possibility.

the opportunity cost can be demonstrated using the production possibility frontier or curve. this graphic shows the total number of possibilities for two products when we have the resources needed and used in an efficient manner. the main resources could be money, labor, and technology. the curve shows that the production of one good increases when the production of the othe
