Factors Affecting Second Language Learning

Learning a second language is always challenging. At the same time, losing a minority language acquired at home can happen more easily than one might expect. Many university students in the U.S. find both situations highly relevant: learning a second language is essential for globalization, while retaining and developing a minority language is crucial for fostering self-esteem and identity. In this talk, drawing on recent studies in second language acquisition (SLA) and instructed second language acquisition (ISLA) from linguistic, cognitive, psychological, social, and educational perspectives, I will explore the central roles of form, meaning, input, output, interaction, and motivation in second language learning. Additionally, I will examine the relationship between language and content in the learning process. To provide practical insights, I will introduce a few successful language programs that demonstrate effective strategies for developing second language skills.

第二言語学習に影響を与える要因

第二言語を学ぶことは常に困難を伴います。同時に、家庭で習得した少数言語を失うことも、想像以上に容易に起こり得ます。アメリカの大学生にとって、これらの問題はどちらも非常に重要です。第二言語の習得はグローバル化に不可欠であり、一方で少数言語を維持・発展させることは、自尊心やアイデンティティを育む上で極めて重要だからです。この講演では、言語学的、認知的、心理的、社会的、教育的観点から行われた「第二言語習得論（SLA）」および「学びの場での第二言語習得論（ISLA）」での最近の研究成果を基に、第二言語習得における「形式（form）」「意味（meaning）」「インプット（input）」「アウトプット（output）」「相互作用（interaction）」「動機付け（motivation）」の中心的な役割を考察します。また、言語と内容の関係についても探ります。さらに、効果的に第二言語の学習を行うための具体的な方法を知る手がかりとして、効果的な言語学習プログラムをいくつか紹介します。
