The behavior described in the question reflects a situation where an educator demonstrates bias in grading, favoring certain students over others. This is characterized as "grading by personal fetish." In this context, "personal fetish" refers to an unfair bias towards specific students, potentially based on personal feelings or preferences, rather than objective criteria.
This concept holds significant importance in educational settings because it undermines the integrity of the grading process. Fair and equitable assessment is essential for fostering a supportive learning environment and ensuring that all students are treated equally regardless of personal biases. Favoritism can lead to a perceived or actual inequity, diminishing the motivation and morale of other students who may feel disadvantaged by an unfair grading system.
Understanding this distinction helps both educators and learners grasp the importance of impartiality in evaluations and encourages practices that uphold ethical standards in education.
