Learning to speak in a foreign language can be a very challenging task for learners. This could be due to the way speaking is taught, the lack of motivation or limited opportunities to practice the foreign language. Visual art has been found to provide a creative and imaginative platform for communication that can stimulate learner involvement and motivation. This study attempted to measure the impact of an art-based approach on teaching English language speaking skills to intensive English language program students at Sultan Qaboos University in the Sultanate of Oman. The researchers used the onegroup pretest and posttest research design. The themes of the art work were based around the 17 sustainable development goals. The results showed a significant improvement in students' speaking ability and overall language level. In addition, the learners were enthusiastically involved in the language learning process. The findings of the study assert the positive impact of visual art on speaking in particular and language proficiency in general.
