코로나19 발생 전후 초등학교 3, 4학년의 수학 학업성취도 변화

Abstract

Objectives The purpose of this study is to empirically verify whether there is a change in the mathematical achievement of 3rd and 4th grade elementary students before and after COVID-19, focusing on latent profile analysis. Methods For this purpose, tests were conducted using the Elementary Math Word-problem Curriculum Based Assessment before the COVID-19 pandemic(2019) and after the COVID-19 pandemic(2020). Excluding the data with missing values, the main results obtained by analyzing the data of 324 3rd graders and 280 4th graders, total 604 students in 2019 and 389 3rd graders and 317 4th graders, total 706 students in 2020 are as follows. Results First, as a result of examining the difference in mathematical achievement for each sub-domain between the 3rd and 4th graders in 2019 and 2020, it was found that there was no significant difference in the 3rd grader, but the 4th grader showed a decrease in mathematical achievement. In particular, the decline in academic ability was remarkable in the areas of figures and measurement, which is important to understand concepts using concrete objects. Second, as a result of latent profile analysis for 3rd grader, the number of latent profile from 4 in 2019 decreased to 3 in 2020. Third, as a result of latent profile analysis for 4th grader, It was confirmed a polarized distribution with decreasing middle class ratio. Conclusions This means that elementary school students also have an achievement gap due to COVID-19. Based on the results of this study, the significance and limitations of this study were discussed.
