What concept refers to the idea that positive expectations can lead to better student outcomes?

The correct concept that refers to the idea that positive expectations can lead to better student outcomes is the Self-Fulfilling Prophecy. This concept involves the phenomenon where a belief or expectation, whether it is positive or negative, can influence a person's behavior to make that belief come true. In an educational context, when instructors or peers hold positive expectations about a student’s potential or abilities, it can enhance the student’s confidence and motivate them to perform better. This belief can manifest in increased effort, persistence, and resilience, ultimately leading to improved academic and practical outcomes.

In contrast, while Self-Assessment Theory and Motivational Development relate to individual student growth and understanding, they do not specifically address the impact of expectations. Expectation Theory, though it may seem relevant, is less commonly recognized in the educational context compared to the clear implications and established research regarding Self-Fulfilling Prophecy. Therefore, it is the Self-Fulfilling Prophecy that best encapsulates the influence of positive expectations on student performance.
