The development of artificial intelligence has influenced instructional practices in elementary schools, particularly in the use of more visual, contextual digital learning media. In Indonesian language learning, the limited use of engaging instructional media that aligns with students’ characteristics often results in low student engagement, as reflected in insufficient attention, participation, and interaction during classroom activities. Therefore, instructional that support active student engagement are needed. This study aimed to enhance student engagement in Indonesian language learning at the elementary school level by using artificial intelligence features in the Canva application as instructional media. The study employed a qualitative Classroom Action Research approach and involved 31 fifth-grade students at a private elementary school in Indonesia. The research was conducted in two cycles, comprising planning, action implementation, observation, and reflection stages. Instructional media were developed using an AI-based Graphic Design Platform features, including Magic Write, Text to Image, and Magic Design. Data were collected through observations, interviews, questionnaires, and documentation. Data were collected through observations, interviews, and questionnaires. Student engagement was measured across four aspects: behavioural, emotional, cognitive, and agentic. Data analysis used both qualitative and quantitative methods. The findings indicate an improvement in student engagement from Cycle I to Cycle II, in the four aspects: behavioural, emotional, cognitive, and agentic. This study concludes that the AI-based Graphic Design Platform can serve as an effective instructional support medium to enhance student engagement in Indonesian language learning at the elementary school level, while maintaining the teacher’s central role in the learning process.
