| Abstract | We present the 2026 SMILE Project betweenChuo University High School (Japan), Rajprachasamasai Phaimathayom Rachadabhisek School (Thailand), and Watsuthiwararam School (Thailand). In January and February, we conducted three online joint classes with approximately 25 students from each school. Our presentation introduces the project’s goals and structure, and highlights how students engaged with their international peers. We also discuss what students learned through the series of lessons, including the development of intercultural communication skills, greater confidence in English, and a deeper understanding of global perspectives gained through collaborative activities. |
