Abstract
Primary school teachers play a critical role in elementary education, and their teaching decisions made in class are of great importance. Based on eye-tracking recordings in class, after-class interviews, and student rating scales, we analyzed teachers' decision-making from the perspective of the ethical theory of utilitarianism and formed a four-quadrant framework. Results showed that Teacher W mostly considered Teacher-Collective Interests, Student-Collective Interests and Student-Individual Interests, while Teacher J focused more on Teacher-Collective Interests and Student-Individual Interests.
