This study described and analyzed how accurately elementary school teachers identified six basic emotions on facial expressions; happiness, sadness, fear, anger, surprise, and disgust. The subjects were 107 elementary school teachers working in Chungnam Province. The study’s purpose was to answer the following research questions: First, how accurately can an elementary school teacher identify facial expressions that represent the six aforementioned basic emotions? Second, is there a difference in elementary school teachers’ ability to judge facial expressions according to teaching experience, age, gender, and so on? It has been confirmed that elementary school teachers in Chungnam Province are, in particular, not good at judging the expression of “fear.” Furthermore, the ability to distinguish facial expressions is developed even after people in their 40s. Moreover, there is no significant difference in the ability to determine facial expressions between male and female teachers.
