Mastery of vocabulary is one of the important elements in Arabic language learning, as vocabulary serves as a foundation for learners to understand and use the Arabic language. However, based on the result of observations and question-answers sessions, the children stated that they had previously learned Arabic but experienced difficulties when asked to recall and mention the vocabulary they had learned. This condition indicates the need for vocabulary reinforcement and repetition through an approach that is appropriate to the characteristic of children. Therefore, this activity aims to provide Arabic language assistance through the singing method as an effort to reinforce children’s vocabulary and their understanding of vocabulary related to family members (الأُسْرَة). The activity employed a participatory assistence method with a Participatory Action Research (PAR) approach through vocabulary explanation, repetition, singing using the melody of the song “lihat kebunku”, and vocabulary guessing games. This approach was chosen to encourage the children of MDA Musthauthin Bateh Gadang to actively participate in the process of reinforcing and understanding vocabulary rather than merely becoming passive listeners. Data were obtained through observation, question-answer sessions, observation during the activity, and documentation. The result showed that the children participated in the activity with a participation rate of 100%. After the activity, the children found it easier to remember, recognize, understand, and mention several Arabic vocabulary items related to family members (الأُسْرَة). In addition, the children showed high enthusiasm throughout the activity and became more confident in pronouncing the vocabulary they had learned. This activity demonstrates that the singing method can be a simple and enjoyable alternative for supporting the reinforcement of Arabic vocabulary among children.
