The lack of English language skills and understanding in Indonesian primary school children is caused by many factors such as, limited teachers, unfamiliarity, unsupportive environment, and various other things. This is a challenge for individuals to learn English and teachers as teachers. In addition to the seriousness of children in learning English, the accuracy of the teacher in choosing the learning methods given to children must also be appropriate. In the current era of digitalization, learning methods through YouTube videos can have an impact on children's knowledge and understanding of English if implemented properly. In this case, learning English can be obtained by listening to videos that apply visual semiotics in it.
