<p><em>The</em><em>_</em><em>low</em><em>_</em><em>mathematics</em><em>_</em><em>learning</em><em>_</em><em>outcomes</em><em>_</em><em>of class X1 Science students</em><em>_</em><em>at SMAN 1 Nan Sabaris are the background for conducting this research. The causal factor</em><em>_</em><em>is</em><em>_</em><em>that</em><em>_</em><em>students</em><em>_</em><em>are</em><em>_</em><em>not</em><em>_</em><em>actively</em><em> </em><em>involved</em><em>_</em><em>in</em><em>_</em><em>learning, so</em><em>_</em><em>students' problem-solving abilities do not develop well. One</em><em>_</em><em>model</em><em>_</em><em>that</em><em>_</em><em>can</em><em>_</em><em>be used</em><em>_</em><em>to</em><em>_</em><em>improve</em><em>_</em><em>students' mathematics learning outcomes is</em><em>_</em><em>by implementing a problem-based</em><em>_</em><em>learning model. This</em><em> </em><em>research</em><em> </em><em>aims</em><em> </em><em>to</em><em> </em><em>determine</em><em> </em><em>the</em><em> </em><em>effect</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em><em>based</em><em> </em><em>learning</em><em> </em><em>model</em><em> </em><em>on the mathematics learning outcomes of class XI IPA students at SMAN 1 Nan Sabaris. </em></p><p><em>This study employs a pre-exsperimental approach utilizing a design that involves only a randomly assigned control group</em><em>. </em><em>The study population consisted af all eleventh-grade science students at SMAN a Nan Sabaris </em><em>for the 2022/2023 academic year. Sampling used a purposive sampling technique, namely class XI IPA<sub>1</sub> as the experimental class and class XI IPA<sub>2</sub> as the control class.

The calculation results show that t<sub>stat</sub> &gt; t<sub>table</sub> means that H<sub>0</sub> is rejected, so it can be concluded that there is an influence of learning using the problem-based learning model on the mathematics learning outcomes of Class X1 Science Students at SMAN 1 Nan Sabaris.</em></p><p> </p><p align="center"><strong>ABSTRAK</strong></p><p>Rendahnya pencapaian pembelajaran matematika siswa kelas X1 IPA SMAN 1 Nan Sabaris yang melatarbelakangi dilakukannya penelitian ini. Faktor penyebabnya adalah partisipasi siswa rendah dalam proses belajar mengajar sehingga perkembangan keterampilan menyelesaikan masalah mereka tidak optimal. Penerapan model <em>problem based learning</em> merupakan satu dari metode yang bisa digunakan untuk meningkatkan pencapaian pembelajaran matematika siswa. Sasaran dari penelitian ini adalah untuk mengetahui pengaruh model <em>problem based learning</em> terhadap hasil belajar matematika siswa. kelas XI IPA SMAN 1 Nan Sabaris. </p><p>Penelitian ini merupakan pra-eksperimen dengan rancangan penelitian <em>randomized control group only design</em>. Subjek penelitian ini mencakup semua siswa kelas XI IPA SMAN 1 Nan Sabaris tahun pelajaran 2022/2023. Pengambilan sampel menggunakan teknik <em>purposive sampling</em> yaitu<em> </em>kelas XI IPA<sub>1</sub> sebagai kelas eksperimen dan kelas XI IPA<sub>2</sub> sebagai kelas kontrol. Hasil belajar yang dianalisis yaitu hasil belajar pada ranah kognitif dengan materi suku banyak.</p><p>Berdasarkan analisis data, rata-rata kelas ekperimen melampaui rata-rata kelas kontrol, yaitu 66,3636 pada kelas kontrol dan 77,2857 pada kelas eksperimen. Hasil analisis uji-t diperoleh t<sub>hitung</sub> = 3,6566 dan <em>t</em><sub>(0,975; 66) </sub>=1,998. Hasil perhitungan terlihat t<sub>hitung </sub>&gt; t<sub>tabel</sub> berarti H<sub>0</sub> ditolak, sehingga dapat disimpulkan bahwa terdapat pengaruh pembelajaran dengan model <em>problem based learning</em> terhadap hasil belajar matematika Siswa Kelas X1 IPA SMAN 1 Nan Sabaris.</p>
