Structural relationships among the subject efficacy of Korean language arts (KLA), KLA instruction, and the factors of reading

This study aims to identify the structural relationships between the efficacy of Korean language arts (KLA) subjects among high school students and the factors of instruction and reading. Toward this end, the study analyzed panel data from the Gyeonggi Institute of Education, which were collected in 2021 from high school learners in Gyeonggi Province. The data were subjected to basic reliability, validity, and correlation analyses to identify relationships among factors. Moreover, I conducted multiple regression analyses to determine the influence of various factors on the subject efficacy of KLA. Additionally, the study performed parallel multiple mediation analyses to estimate indirect effects and causal relationships. This study contributes to the establishment of a foundation of a comprehensive understanding of the phenomena of reading development and KLA education.
