Answer:
b. teachers' expectations were powerful in influencing the bloomers' behaviors.
Explanation:
Recall that Rosenthal and Jacobson (1968) told teachers that some of their students were "bloomers." Consequently, those students actually performed better than students who were not labeled as bloomers. This finding suggests that teachers' expectations were powerful in influencing the bloomers' behaviors.
In the work by Rosenthal and Jacobson (1968) titled Pygmalion in the Classroom it was shown that teachers expectation from from students influenced their performance. When the teachers in the study were told that certain students in their classrooms were bloomers, their expectations from those students became high and consequently, the students had better results than their peers
