A Study on the Influence of Halo Effect: Teaching Evaluation in Junior and Senior High Schools

Abstract

Teaching evaluation plays an indispensable role in continuously improving the education system and promoting talent cultivation in today's society. The Halo effect, as a common cognitive bias, also affects educational evaluation all the time. Therefore, understanding how the Halo effect affects education evaluation, how it affects, and how to find ways to reduce the deviation caused by the Halo effect are the current core content. Based on previous scholars' research on the Halo effect and teaching evaluation, this paper adopts the method of systematic literature review, and analyzes, incorporates, and summarizes how the Halo effect operates in education evaluation and how much it has influenced from different perspectives, including students and teachers, subjects, grade of students, and different types of schools. Through literature collection, it has been found that both parents and students map to other aspects due to a certain characteristic of the teacher, such as the teaching ability of a certain course. First impressions can affect the evaluation of other abilities. And students often have biases based on the appearance and clothing of teachers when they first meet them and then pass these biases on to the teachers, which can have a significant impact on teaching evaluation. These are all common. The deviation caused by the Halo effect can be reduced mainly through three aspects: first impression, understanding in detail and view from a developmental perspective, and improving professional quality.
