This study was to analyze the correlation between the level of disgust against anatomy and past experience of anatomy, and find out the effect of the level of disgust on biology teaching self-efficacy and awareness of the importance of anatomy. As research subjects, this study selected 72 elementary school teachers for the gifted who participated in an elementary school science teacher training program for the gifted. The analysis results can be summarized as follows. Firstly, it was found that the level of disgust was higher in those with disgust against anatomy than those without disgust. Secondly, those without disgust had more experience of anatomy in the past than those with disgust. As a negative correlation was clearly found between the level of disgust and past experience of anatomy, this study found out that the more past experience of anatomy they had, the less disgust they felt against anatomy. Thirdly, those without disgust had more biology teaching self-efficacy after anatomy experiments, so this study found out that the level of disgust affected the improvement of biology teaching self-efficacy. Lastly, those without disgust were found to aware the importance of anatomy in biology class much more than those with disgust.
