Final answer:
The scenario with Ms. Valentino and Javier is an example of a self-fulfilling prophecy, where teacher expectations influence student performance. Research has shown this effect to be particularly significant among disadvantaged students.
Step-by-step explanation:
The scenario described illustrates c. a self-fulfilling prophecy. This is when a teacher's initial expectations about a student's performance may unconsciously influence their behavior towards the student, which in turn can affect the student's performance, confirming the original expectations. The story of Ms. Valentino and Javier exemplifies this effect, where the teacher's early judgment based on Javier's appearance and behavior might have influenced her interaction with him, potentially contributing to his low grades. Rosenthal and Jacobson (1968) found that teacher expectations can have a significant impact on student performance, particularly for disadvantaged students. This highlights a larger issue within education systems that tend to favor students from higher socioeconomic backgrounds.
