言語少数派の子どもの日本語認知力の獲得に関わる要因 : 母語と日本語の関係に注目して  [in Japanese] Factors Affecting the Japanese Language Acquisition of Language Minority Children : Focusing on the Relation between Their Native Language and the Japanese Language  [in Japanese]

The purpose of this study is to investigate the learning difficulties that language minority children have in their course of study, explore the factors that affect their acquisition of language proficiency, and identify the most relevant factor. Focusing on the Japanese language proficiency of children whose native language is Chinese and who attend Japanese public schools, I have analyzed the significance of factors such as age when coming to Japan, length of stay in Japan, and native language ability. As a result, I have found that it is the native language proficiency that is most closely related to the students' Japanese language proficiency. Based on these findings, I propose that in the process of acquisition of Japanese language proficiency, it is important and necessary that the students maintain and further develop their native language ability.
