<p>This study investigated the teachers’ experiences using a web-based language teaching tool to support English language learning in rural primary schools. The web-based language teaching tool was developed to match the school curriculum and the teachers’ lessons and implemented in this study. On the web-based language teaching tool, there are lessons and activities for students to practice at home; therefore, both teachers and students have access to the tool. After completing each lesson, the teachers were asked to write reflection diaries describing their experience on using this tool to teach their students. Then the thematic coding of the teacher’s diary is used in the study to analyze the results regarding the teachers’ experiences using the web-based language teaching tool to teach their students, challenges and successes they encountered during the teaching process, and how the teachers perceived the differences between using the tool and traditional classroom teaching. The results show that the overall experience of the teachers is positive. However, there were some challenges found during the implementation such as design limitations and technical issues. The results also show that teachers in rural primary schools still prefer classroom teaching to online teaching for some reason. The findings of the study can contribute to the development of the effective solutions for schools in rural areas, offer valuable implications for teacher training, and further research on technology-assisted learning.</p>
