Development of Kanji Learning Materials for Dysgraphia and EEG Measurement

The primary aim of the research project is to develop instructional materials for Kanji learning, specifically targeting students facing difficulties or disabilities in writing. The effectiveness of traditional methods, emphasizing extensive reading and extensive handwriting to enhance brain working memory, has been questioned due to significant accumulations of fatigue and stress revealed in EEG results. To address these concerns, an innovative approach is proposed, focusing on the efficient development of a method to train the brain’s working memory in Kanji learning, heightened by increased awareness of spatial cognition. This method is implemented in high schools and universities, with subsequent measurement of its effects. Iterative improvements is made based on the school feedback and the effectiveness assessments, including enlarging character size and enhancing spatial cognition skills associated with characters to optimize the efficacy of character learning. In this study, we introduce an evaluation of the proposed educational method by the measurement of rhythms in the Electroencephalograms (EEGs).
