This research was conducted to reflect on teachers' performance and analyze the improvement of the quality of student learning in Indonesian language subjects. This research aims to explore the use of poetry learning strategies through CRT. The focus is on improving the quality of Indonesian language learning by implementing CRT in the students' environment. This research design uses a case study. Based on the implementation of Field Experience Practices, it was found that students looked sleepy and easily bored while learning the Indonesian language. This case was because Indonesian learning displays too much long text. So, the Culturally Responsive Teaching (CRT) approach was implemented to solve the problem. Teaching using the CRT approach in the Indonesian language subject was carried out for eight weeks with two sessions of meetings in class X.1 of State Senior High School 1 Jember. The results showed that students actively participate in the learning process. Besides, learners' learning activities support the existence of learning products. The Indonesian language learning product produced is a musicalization video of poetry. The product also received feedback from the teacher in the form of appreciation, enthusiasm, and motivation for students. The findings of this research show that improving the quality of learning can be achieved by utilizing CRT as a context in the development of texts and their instruction. The meaningfulness of the learning can be seen from the students' deep understanding, enabling them to grasp the benefits and functions of studying texts in Indonesian. This study recommends implementing Culturally Responsive Teaching in Indonesian language learning subjects to increase student learning activities. One of the activities of Culturally Responsive Teaching is creating appropriate activities for students' cultural backgrounds in the form of musicalization poetry.
