The integration of generative AI in the field of education is actively being explored. In particular, ChatGPT has garnered significant interest, offering an opportunity to examine its effectiveness in English as a foreign language (EFL) education. To address this need, we present a novel learning platform called RECIPE (Revising an Essay with ChatGPT on an Interactive Platform for EFL learners). Our platform features two types of prompts that facilitate conversations between ChatGPT and students: (1) a hidden prompt for ChatGPT to take an EFL teacher role and (2) an open prompt for students to initiate a dialogue with a self-written summary of what they have learned. We deployed this platform for 213 undergraduate and graduate students enrolled in EFL writing courses and seven instructors. For this study, we collect students' interaction data from RECIPE, including students' perceptions and usage of the platform, and user scenarios are examined with the data. We also conduct a focus group interview with six students and an individual interview with one EFL instructor to explore design opportunities for leveraging generative AI models in the field of EFL education.

翻译：摘要：生成式人工智能在教育领域的整合正在被积极探索。特别是ChatGPT引发了广泛关注，为检验其在英语作为外语（EFL）教育中的有效性提供了机遇。为应对这一需求，我们提出了一种名为RECIPE（基于交互式平台的EFL学习者借助ChatGPT进行作文修改）的新型学习平台。该平台具备两类促进ChatGPT与学生对话的提示词：（1）引导ChatGPT扮演EFL教师角色的隐藏提示词；（2）学生基于自撰学习总结启动对话的开放提示词。我们在213名修读EFL写作课程的本硕学生及七位讲师中部署了该平台。本研究通过RECIPE收集学生交互数据，包括学生对平台的感知与使用情况，并利用这些数据考察用户场景。同时，我们开展了由六名学生组成的焦点小组访谈及对一位EFL讲师的个别访谈，以探索在EFL教育领域利用生成式人工智能模型的设计契机。
