The purpose of this study was to propose instructional-learning strategies for designing effective software education investigating gender differences in computational thinking, creativity and academic interest on elementary SW education. 86 elementary school students who had SW education for 4 months, consisting of 49 boys (57%) and 37 girls (43%), participated for this study. They responded surveys regarding computational thinking, creativity, and academic interest. With the use of independent t-tests, this study found that there was significant differences in creativity and academic interest between boys and girls at elementary SW education. The mean of creativity of girls was higher than that of boys. however, the mean of academic interest of males was higher than that of girls. On the other hand, there was no difference in computational thinking between boys and girls. In conclusion, this study suggests design and implementation of successful SW education class considering gender.
