The study reports on a service-learning project of psychology students at a university in Southern Thailand under an English listening and speaking course. The learners created a set of multilingual materials addressing the issues of their local communities, deploying the CREDIBLE approach and Positive Discourse Analysis, a complementary approach to Critical Discourse Analysis. The project addresses online-learning stress among university students by analysing the discursive strategies employed by successful campaign materials engaging in similar issues. A survey of online-learning primary stressors was also conducted. The discourse analysis and survey findings were used in the students’ designs. The materials were a set of multilingual informational posters on stress and a relaxation video for managing stress. The learners demonstrated their spoken English skills through constant negotiations and oral academic reports. The paper serves as a viable resource for integrating service-learning in English listening and speaking skills.
