隨著全球化推進，英文作為主要溝通工具的重要性日益突出。雖然過去研究 已證明智慧行動裝置和行動學習工具能顯著提升 EFL 學習者的學習效果，但大 多數研究僅集中於個人化或情境化教學方法，對於如何結合兩者以提升口說和寫 作能力的探討仍有不足。隨著短影音和自然語言處理技術的發展，如何有效整合 這些新興科技，為 EFL 學習者提供更具互動性與真實性的學習體驗，成為重要 的研究議題。 為了解決上述問題，本研究發展了一個名為ClipTalk的系統。該系統使用影 片辨識技術(VTR)和 GPT 為EFL學習者打造個人化的學習體驗。系統經由分析 影片內容，為學習者提供相關字彙、片語和例句，並結合GPT 設計一套文法檢 查機制，幫助學習者糾正寫作並從錯誤中學習。此外，智慧情境對話器人基於影 片內容與學習者互動，提供更多練習機會。為了探討個人化與情境化學習對於學 習者英文寫作與口說能力的影響，本研究將65名參與者分成三組，以便後續實 驗的進行，幫助學習者將學到的英文應用到現實生活中。 研究結果顯示，實驗組學習者的寫作和口說能力顯著提高，尤其是字彙使用 和句子結構。VTR 情境字彙、文法檢查機制與智慧聊天機器人對於提高學習者 的學習成效及動機特別有效。問卷與訪談結果表明，學習者對ClipTalk持正面態 度，認為這對他們的學習有幫助。總體而言，本研究證明了個人化與情境化學習 方法能有效提升EFL學習者的英文口說與寫作能力，而ClipTalk 作為學習輔助 工具能有效提升他們的學習動機與表現。;As globalization continues to grow, English has become a key language for communication worldwide. Many studies have shown that using smart mobile devices and mobile learning tools can help students learning English as a foreign language (EFL) improve their skills. However, most research has focused only on personalized or contextualized teaching methods, with insufficient research on how combining both approaches can improve students′ speaking and writing skills. With the rise of short video platforms and new technologies like natural language processing, it is important to explore ways to combine these tools to offer more interactive and real-life learning experiences for EFL learners. Previous studies have not thoroughly explored how the combination of personalized and contextualized learning can enhance EFL learners′ speaking and writing abilities. To address this issue, this study developed a system called ClipTalk. This system uses video recognition technology (VTR) and GPT to create personalized learning experiences for EFL learners. The system analyzes video content to provide learners with relevant vocabulary, phrases, and example sentences, and it includes a grammar checking tool to help students correct their writing and learn from their mistakes. Additionally, an intelligent contextual chatbot interacts with students based on the videos′ content, providing more practice opportunities. This study involved 65 participants who were divided into three groups for follow-up experiments to help learners apply what they have learned to real life. The results indicated that students in the experimental group significantly improved their writing and speaking skills, especially in vocabulary usage and sentence structure. The VTR technology, grammar-checking tool, and intelligent chatbot were particularly effective in enhancing learners′ outcomes and motivation. Survey and interview results revealed that students had a positive attitude toward ClipTalk, finding it helpful for their learning. Overall, this study shows that combining personalized and contextualized learning methods can effectively improve EFL learners′ English speaking and writing skills, with ClipTalk serving as a useful tool for enhancing motivation and performance.
