<![CDATA[Permasalahan dalam penelitian ini diangkat karena hasil wawancara terhadap guru matematika di SMPN 18 Kota Jambi mengindikasikan bahwa kemampuan representasi matematis siswa Kelas VIII tergolong rendah serta tidak sedikit dari mereka yang pasif dalam belajar. Oleh karena itu, penelitian ini menitikberatkan pada penerapan pembelajaran berdiferensiasi berdasarkan gaya belajar menggunakan model PjBL terhadap peningkatan representasi matematis siswa. Penelitian eksperimen ini menggunakan metode True Experimental Design dengan tipe Pretest-Posttest Control Group Design. Berdasarkan hasil pengambilan sampel acak, diperoleh kelas VIII F sebagai kelompok eksperimen dan kelas VIII G sebagai kelompok kontrol dengan jumlah 28 siswa pada setiap kelasnya. Penelitian dilakukan pada materi SPLDV di semester ganjil tahun ajaran 2023/2024. Dalam memperoleh informasi digunakan instrumen berupa angket, lembar observasi dan tes. Temuan penelitian menunjukkan bahwa penerapan pembelajaran berdiferensiasi berdasarkan gaya belajar dengan Project Based Learning efektif dalam meningkatkan kemampuan representasi matematis siswa. Peningkatan tertinggi diperoleh oleh siswa dengan gaya belajar kinestetik, yang mencapai kriteria tinggi dengan skor peningkatan sebesar 0,743.The problem in this study was raised because the results of interviews with mathematics teachers at SMPN 18 Jambi City indicated that the mathematical representation skills of Class VIII students were low and many of them were passive in learning. Therefore, this study focuses on the application of differentiated learning based on learning styles using the PjBL model to improve students' mathematical representations. This experimental research uses the True Experimental Design method with the Pretest-Posttest Control Group Design type. Based on the results of random sampling, class VIII F was obtained as the experimental group and class VIII G as the control group with a total of 28 students in each class. The research was conducted on SPLDV material in the odd semester of the 2023/2024 school year. In obtaining information, instruments such as questionnaires, observation sheets and tests were used. The research findings show that the application of differentiated learning based on learning styles with Project Based Learning is effective in improving students' mathematical representation skills. The highest improvement was obtained by students with kinesthetic learning style, which reached high criteria with an improvement score of 0.743. ]]>
