Penggunaan model pembelajaran problem based learning masih belum diterapkan dengan maksimal menjadi salah satu faktor rendahnya tingkat kemampuan literasi sains siswa khususnya pada mata pelajaran fisika. Penelitian ini bertujuan untuk menganalisis perbedaan yang signifikan dalam kemampuan literasi sains fisika siswa SMA sebelum dan sesudah diterapkan model problem based learning. Jenis penelitian ini adalah quasi eksperimen dengan desain penelitian yaitu nonequivalent countrol group design. Populasi pada penelitian ini adalah seluruh siswa kelas XI SMA Labschool Unsyiah dengan teknik pengambilan sampel secara purposive sampling yang terdiri dari dua kelas yaitu XI Enginering yang berjumlah 35 siswa sebagai kelas eksperimen dan XI Sains Teknologi yang berjumlah 35 siswa sebagai kelas kontrol. Instrumen penelitian yang digunakan yaitu tes kemampuan literasi. Teknik pengolahan data menggunakan uji independent sample t-test setelah pengujian prasyarat terpenuhi. Berdasarkan hasil uji independent sample t-test pada nilai posttest diperoleh nilai thitung (1,853) ≥ ttabel (1,667) maka Ha diterima. Oleh karena itu, dapat disimpulkan bahwa terdapat perbedaan yang signifikan dalam kemampuan literasi sains fisika siswa SMA sebelum dan sesudah diterapkan model problem based learning.

The use of problem based learning model has not been implemented optimally, which is one of the factors in the low level of students' science literacy skills, especially in physics. This study aims to analyze significant differences in the scientific literacy skills of high school students before and after the application of the problem based learning model. This type of research is a quasi experimental study with a nonequivalent pretest posttest group design. The population in this study were all students of class XI SMA Labschool Unsyiah with a purposive sampling technique consisting of two classes, namely XI Engineering, totaling 35 students as the experimental class and XI Science Technology, totaling 35 students as the control class. The research instrument used was a science literacy ability test. The data processing technique used an independent sample t-test after the prerequisite test was met. Based on the results of the independent sample t-test on the posttest value, the t count value (1.853) ≥ t table (1.667) was obtained, so Ha was accepted. Therefore, it can be concluded that there is a significant difference in the science literacy skills of high school students before and after the application of the problem based learning model.
