Vocab Boss 4 is the fourth level in the Vocab Boss series, designed for learners working at the JACET 3000–4000 level and around A2 on the CEFR scale. The book helps students move from simply “remembering” vocabulary to actually “using” it. Across 10 modules, learners study 1,200 carefully selected words and expressions through clear definitions, Japanese translations, pronunciation guides, collocations, and example sentences.
The Review & Retrieval section at the end of each module uses evidence-based learning techniques to strengthen long-term retention through active recall. Combined with the Confidence Tracking System, these activities encourage learners to reflect on their progress, build confidence, and gradually transform passive vocabulary knowledge into vocabulary they can understand, recall, and use with confidence.
The goal of Vocab Boss is simple: to help learners become the boss of their vocabulary, not the other way around.
『Vocab Boss 4』は、JACET 3000〜4000語レベル、CEFR High A2程度の学習者を対象とした語彙教材です。本書では、1,200の重要語彙・表現を学習し、「覚える」だけでなく「使える」語彙へと発展させることを目指します。
各語彙には、日本語訳、発音ガイド、コロケーション、例文を掲載し、実際の使用場面を意識しながら学習を進めることができます。また、各Module末の「Review & Retrieval」では、想起(Retrieval)を活用したアクティビティを通して、長期的な記憶の定着を促します。
さらに、「Confidence Tracking System」により、自分の理解度や自信の変化を確認しながら学習を進めることができます。語彙を「知っている」状態から、「思い出せる」「使える」状態へと育てることが、本書の大きな目標です。
Vocab Boss の目標はシンプルです。語彙に振り回されるのではなく、自分の語彙を自在に使いこなせる学習者を育てることです。
