<p>The OECD-PISA results state that the mathematical literacy ability of students in Indonesia is relatively low. The aims of this study were: 1) To find out the increase in mathematical literacy skills by applying the <em>Discovery Learning</em> model, 2) To find out the increase in mathematical literacy skills by applying the <em>Inquiry Learning</em> model, 3) To find out whether mathematical literacy skills are increased by the application of the <em>Discovery Learning</em> model rather than <em>Inquiry Learning</em>.  This study utilized a quantitative approach.  The sampling technique was purposive sampling with two experimental groups in eighth-grade SMPN 1 Bae Kudus.  The experimental group I applied the <em>Discovery Learning</em> model and the experimental group II applied the <em>Inquiry Learning</em> model. The data analysis technique used the t-test and the Mann-Whitney U test. The results of this study were: 1) The t-test has given a significance level of 0,00 &lt; 0,05. This means that there was a significant increase in the mathematical literacy skills of students in the experimental group I after the application of the <em>Discovery Learning</em> model with an increase in N-gain of 71%, 2) The t-test has given a significance level of 0,00 &lt; 0,05.  This means that there was an increase in the mathematical literacy skills of students in experimental group II after applying the <em>Inquiry Learning</em> model significantly with an increase in N-gain of 60%, 3) The Mann-Whitney U test has given a significance level of 0,048 &lt; 0,05 which indicated that literacy skills students' mathematics was further improved by the application of the <em>Discovery Learning</em> rather than <em>Inquiry Learning </em>model.</p><p> </p><p>Hasil OECD-PISA menunjukkan bahwa kemampuan literasi matematika siswa di Indonesia relatif rendah. Tujuan penelitian ini adalah: 1) Mengetahui peningkatkan kemampuan literasi matematika dengan penerapan model <em>Discovery Learning</em>, 2) Mengetahui peningkatkan kemampuan literasi matematika dengan penerapan model <em>Inquiry Learning</em>, 3) Mengetahui apakah kemampuan literasi matematika lebih meningkat dengan diterapkannya model <em>Discovery Learning</em> daripada <em>Inquiry Learning</em>. Penelitian ini menggunakan pendekatan kuantitatif. Teknik pengambilan sampel adalah <em>sampling purposive</em> dengan dua kelas eksperimen di kelas VIII SMPN 1 Bae Kudus. Kelas eksperimen I diterapkan model <em>Discovery Learning</em> dan kelas eksperimen II diterapkan model <em>Inquiry Learning</em>. Teknik analisis data adalah menggunakan uji-t dan uji Mann-Whitney U. Hasil penelitian ini adalah: 1) Pada uji t memberikan taraf signifikansi  Artinya terdapat peningkatan kemampuan literasi matematika peserta didik kelas eksperimen I setelah diterapkannya model <em>Discovery Learning</em> secara signifikan dengan kenaikan N-gain sebesar , 2) Pada uji t memberikan taraf signifikansi  Artinya terdapat peningkatan kemampuan literasi matematika peserta didik kelas eksperimen II setelah diterapkannya model <em>Inquiry Learning </em>secara signifikan dengan kenaikan N-gain sebesar , 3) Pada uji <em>Mann-Whitney U</em> memberikan taraf signifikansi  yang menunjukkan bahwa kemampuan literasi matematika peserta didik lebih meningkat dengan diterapkannya model <em>Discovery Learning</em> daripada <em>Inquiry Learning.</em></p>
