PenDropは、「アウトプット」 にこだわった、本気で英語を身につけたい人のためのトレーニングアプリです。 ただ英文法を「読む」、「穴埋め」、「並び替え」だけでは、英語力はつきません。 本アプリは、「一から英文を組み立てる(英作文ドリル)」 と 「記憶に定着させる(単語カード)」 という2つの強力なアウトプットサイクルを回すことで、実践的な英語力を確実に養います。 【PenDropの3つのコアメソッド】 「書く」から身につく!実践型・文法ドリル 選択問題ではありません。自分の頭で考え、ゼロから英文を組み立てるトレーニングです。 文法・構文ごとに体系化されたドリルで、曖昧な知識を「使える武器」に変えていきます。 間違えた箇所はその場でAIが徹底解説。なぜ間違えたのかを即座に理解できます。 脳科学に基づく「忘却曲線」単語学習 人間の記憶の仕組み(エビングハウスの忘却曲線)を利用し、忘れかけた瞬間に復習を促します。 覚えた単語は表示間隔が広がり、苦手な単語は重点的に出題。最短時間で最大の語彙力を構築します。 AIによる精密な添削コーチング あなたが書いた英語をAIが瞬時に分析。文法的な正誤だけでなく、より自然な表現への書き換えも提案します。 独学では気づけない「自分のクセ」や「ニュアンスのズレ」を修正し、洗練された英語へ導きます。 【こんな学習者に最適です】 インプット学習(読む・聞く)ばかりで伸び悩みを感じている方 瞬間的に英文を組み立てる「英語脳」を作りたい方 英検や入試のライティングで高得点を狙いたい方 ただの間違い直しアプリではありません。 PenDropで、圧倒的なアウトプット体験を始めましょう。
