<![CDATA[Indonesian language learning in elementary schools plays an important role in developing students’ language skills, critical thinking, and communication abilities. However, students’ learning outcomes in Indonesian language subjects are still often below expectations because the learning models used do not sufficiently involve students actively. One alternative to address this problem is the Problem Based Learning (PBL) model. This study aims to examine the effectiveness of PBL in improving Indonesian language learning outcomes among fifth-grade elementary school students. The study employs a library research method by analyzing various scientific sources, including journals, research articles, books, and academic documents published between 2021 and 2026. Data were collected through documentation study, while data analysis used qualitative analysis techniques consisting of data reduction, data presentation, and conclusion drawing. The findings indicate that the implementation of PBL can improve students’ Indonesian language learning outcomes by increasing learning activity, critical thinking ability, problem-solving skills, and understanding of learning materials. In addition, this model encourages students to become more involved in the learning process, making learning more meaningful in the elementary school context. Therefore, PBL can be used as an effective and relevant alternative learning model to improve Indonesian language learning outcomes among fifth-grade elementary school students.]]>
