Direction for Improving Science Gifted Education for Middle School Students: Based on the Analysis of Curriculum and Academic Achievement

Abstract

This study used the International Junior Science Olympiad (IJSO) syllabus as an international benchmark to compare South Korea’s national science curriculum with the Korea Junior Science Olympiad (KJSO) regular curriculum and to connect curriculum gaps with achievement data from KJSO participants. The IJSO standards emphasize interdisciplinary integration, quantitative analysis, and specific inquiry/experimental skills; however, the national curriculum shows a content gap (Gap 1) in quantitative and experimental inquiry competencies, which the KJSO program addresses through enrichment and acceleration. Nevertheless, a structural gap (Gap 2) persists because the KJSO curriculum operates in fragmented disciplinary modules rather than an integrated structure. Achievement analyses indicated relatively lower performance in domains missing from the national curriculum — especially quantitative chemistry and analytical thinking in biology — suggesting that Gap 1 functions as a cognitive-load point that directly constrains student performance. These findings imply that while KJSO can bridge national curricula and international standards, targeted methodological supports at gap points and the gradual introduction of basic quantitative and analytical elements into the national curriculum are needed.
