The purpose of this study is to derive suggestions and implications to strengthen the science curriculum articulation
of Korea through comparative analysis with focus on the articulation of science curriculum concerning the ‘light’ and
‘electricity’ concepts in seven countries. National science curriculum of each country complied from NCIC comparatively
analyzed the concept of ‘light’, and ‘electricity’ based on Tyler’s curriculum organizing principle(1949) that is vertical, and
lateral connectivity. As a result, the concepts of big idea about ‘light’ and ‘electricity’ was utilized internationally to
strengthen the linkage between grades and subjects. As students advance to higher grades, their learned concepts repetition
based on the spiral curriculum and concepts expand from simple phenomenon to complicated and discrete theorem. In Korean
science curriculum that learning standard was not clear on the range of teaching concepts and level. In addition, lateral connectivity
was less compared to other countries. In addition, Korean science curriculum requires appropriate tools to strengthen
curriculum linkage and when configuring the science curriculum, reflect demand of curriculum experts, teachers, students and
parents.
