Answer: Self fulfilling prophecy
Explanation: Due to the fact that Luis did poorly in the exam, which gave the teacher the impression that Luis was lazy and unintelligent. According to Symbolic interactionists, every grade or behaviour indicates how one should be assessed, in this case Luis, thus labelling individual students. Lewis was labelled as lazy and unintelligent because of bad exam here.
After that, the teacher started paying only negative attention to Louis, he saw him as lazy, so he judged his behaviour as lazy, and saw him as unintelligent, based on the grade on the exam.
Based on the teacher's negative attention to Luis, Lewis begins to lose interest in school, which is self fulfilling prophecy. When a person, student, or event is expected to do something concrete, say, something as bad as in this case, then it is most likely that that person or student will "fulfil prophetic expectations" and begin to behave in a bad way.
