The purpose of this study was to look into how the STEAM Program, which is based on
simulatory activity consisting of 5 jobs in the natural sciences or engineering fields, influences
career development of elementary school students. The subjects of this study were the 4th grade
students of an elementary school located in Incheon city. The study was carried out for two
groups, an experiment group(n=24) and control group(n=23). The program was constructed from the
curriculum in social studies, moral education and physical education. The major findings of this
study were as followings; First, there was no significant difference of career maturity between the
experimental group and the control group. Second, the percentage of vocational types of the
experimental group increased in the 6 fields, compared to the control group, where it decreased.
Third, Through concrete and realistic job experience and information in the fields of natural
sciences or engineering, students' choice of jobs was widely broadened. Career maturity was
meaningfully correlated(p<.01) with extroversion, openness, friendship, and sincerity factors. It was
especially strongly correlated with sincerity. The correlation of career maturity and character was
lessoned through the STEAM program. In the relation between the percentage of vocational
character type and the factor of students' character, the correlation of the two factors above
showed highly positive effects after the completion of the program.
