漢字書字の習得が困難な学習障害児に関する研究の動向

Research trends on children with learning disabilities who have difficulty acquiring kanji writing skills

要旨：本研究は，漢字書字の習得が困難な学習障害児における国内の研究動向を調査し，今後の課題を明らかにすることを目的にした．漢字書字の習得が困難な要因には視覚情報処理や聴覚情報処理を問題とする報告が多かったが，書字成績に認知スタイルや筆順の正確さが寄与した報告も見られた．また介入研究では，単一事例研究法を用いた研究は少なかった．今後は単一事例研究法を用い，認知スタイルだけでなく，書字運動や運動覚心像に着目した研究や，各児童の特性に適応した介入方法をフローチャート化し自主学習しやすいツールを開発していくことが求められる．併せて，Information and Communication Technology（ICT）を活用した支援の普及も重要である．

　The purpose of this study was to investigate the domestic research trends and clarify future issues in children with learning disabilities who have difficulty acquiring kanji characters. Although there is robust research on visual and auditory information processing as factors that impede kanji writing, there are also reports in which recognizing style and accuracy of stroke order contributed to writing performance. In addition, the intervention study highlighted few studies using single case experimental designs. Future research should include single case experimental designs, focusing not only on cognitive styles, but also on writing movements and kinesthetic images. Furthermore, a flow chart of an intervention method adapted to the characteristics of each child, as well as a tool that facilitates self-directed learning should be created. At the same time, it is also important to disseminate support using ICT.
