This study intends to provide basic materials for preparing teacher aptitude and character based on the
objective understanding by individual characteristics, by verifying DISC behavior type and current status of
teacher aptitude and character of would-be early childhood teachers studying in teacher training institutions,
as well as the correlation between two variables. For the purpose of this, this study analyzed the data
oriented to 168 students of Early Childhood Education of three-year colleges located in Gyeonggi-do and
Chungcheong-do, under the curriculum allowing the obtainment of certificate of “The Second-Level Regular
Kindergarten Teacher”. According to the research result, firstly, the behavior type of would-be early
childhood teachers which is most frequently observed was Interaction type (I) registering up to 44.0%,
followed by Supportive type (S) by 28.6%, Compliance type (C) by 14.3% and Dominance type (D) by
13.1%. Secondly, regarding the 15 subtests in terms of teacher aptitude and character of would-be early
childhood teachers, the average score turned out to range from 3.02 to 4.24 (Full mark: 5.0). While higher
average score was observed in vocation, view of teachership and sensitivity, the lowest average score was
observed in psychological stability. Thirdly, the Interaction type (I) in the relationship between behavior
characteristics and teacher aptitude and character of would-be early childhood teachers showed a higher
positive correlation with sympathy, expressive ability, leadership and passion of teacher aptitude and
character, but it showed a lower positive correlation with problem-solving ability, inquiry ability and
planning ability. The Supportive type (S) showed a higher positive correlation with service, sacrifice,
cooperation and passion of teacher aptitude and character, but there was no significant correlation with
psychological stability, linguistic and communication ability. Regarding the Compliance type (C), a higher
positive correlation was shown with judgement, planning ability, problem-solving ability and inquiry ability
of teacher aptitude and character, while there was no significant correlation with psychological stability.
Regarding the Dominance type (D), a higher positive correlation was displayed with leadership, linguistic
and communication ability, sincerity and responsibility of teacher aptitude and character, while there was
lower positive correlation with sensitivity. This study has significance in the sense that it analyzed behavior
characteristics and teacher aptitude and character of would-be early childhood teachers studying at teacher
training institutions, and implies that many efforts are required to maximize strength by each behavior
characteristic and minimize the weakness while teacher training institutions are constantly offering teacher
aptitude and character of early childhood teachers.
