Outline of Final Research Achievements

In order to investigate the relationship between the process of second language learning and first language transfer, a choice test of English participle forms (-ing and -ed forms) was administered to junior high and high school students, as well as to university students. The results suggest that previously learned content influences how we learn new content. The simulation also investigated the effect of first language on the choice of the resolution of the relative pronoun clause, and the results were in line with previous studies. A questionnaire survey was also conducted on teaching formats for both face-to-face and online environments in order to develop future teaching materials and methods.

Academic Significance and Societal Importance of the Research Achievements

外国語学習には母語の影響があることが指摘されてきた。一方、母語知識の転移・干渉に関しては様々な要因が関係してくるため、ある現象のどこまでが母語による影響なのか特定すること容易ではない。本研究では、ニューラルネットワークモデルを用いて様々な学習条件のもとでの学習過程をシミュレーションすることで外国語学習と母語知識の関係を明らかにできる可能性を示唆している。さらに、本研究の成果を踏まえた教材・教授法の開発の準備段階として、学習者視点による従来の対面授業とオンライン形式の授業形態の比較を行った。
