Abstract

In this paper, we conducted a case study for lower grade elementary school students by modifying and applying lesson plan of CS Unplugged v4.1. Software education was introduced in the 2015 revised national curriculum in Korea, but the starting age is later than the other countries. Also most projects and researches are concentrated in higher grade elementary school students. It is necessary to lower the entry age of software education in order to nurture human resources leading the fourth industrial revolution era. In this study, we modified the lesson plan of CS Unplugged v4.1 to be suitable for lower grade elementary school students in Korea. The participants were 18 students in the first grade of elementary school, pre&post-test on understanding of computer science principles were conducted for examining the effectiveness. As a result, the average was significantly higher in the post-test than in the pre-test, with t=-2.222, p=0.040(p < .05).
