Abstract
The aim of this study is to explore an effective Japanese language teaching method and course development for Vietnamese bridge system engineers and IT communicators. Firstly, the pre-course analysis showed that learners faced difficulties in both Japanese language performance and communicative competence. Based on this, IT Japanese and business fundamental skills were focused in the study contents. Besides, as the learners’ proficiency was evaluated as intermediate and upper intermediate level, the flipped classroom and cooperative language learning were implemented, which could contribute to learners’ autonomous learning and interaction improvement. As a result, achievement was obtained and can be applied for future issues.
