“…Selain itu menurut Ennis pada tahun 1991 (Mahmuzah, 2015: 65) berpikir kritis merupakan suatu proses penggunaan kemampuan berpikir secara rasional dan reflektif yang bertujuan untuk mengambil keputusan tentang apa yang di yakini atau dilakukan. Berdasarkan beberapa pernyataan tersebut, kemampuan berpikir kritis merupakan salah satu indikator dari berpikir tingkat tinggi melalui suatu proses berpikir rasional dan reflektif, selain itu berpikir kritis sangat diperlukan untuk merangsang pola pikir siswa dalam suatu pembelajaran (Sutarsa & Puspitasari, 2021;Iswara, Darhim, & Juandi, 2021). Berpikir kritis juga dapat merangsang siswa dalam mengambil keputusan yang tepat berdasarkan fakta yang ada (Afriansyah, Herman, Turmudi, & Dahlan, 2021).…”

The ability to think critically is still not optimal, this is because learning is not optimal. Therefore we need a variety of learning processes both approaches, methods, or innovative learning models to be able to improve the ability to think critically and mathematically. Learning models that support improving mathematical critical thinking skills are PBL models and DL models. The purpose of this study is to determine the mathematical critical thinking skills of students who get the PBL model better than the DL model. The research method used was a quasi-experimental study with a population of all grade XI students of SMA Negeri 11 Garut. Due to purpose sampling, the samples taken are two classes, namely class XI MIPA 5 as the experimental class I which gets the PBL model, and class XI MIPA 8 as the experimental class II which gets the DL model. The research instrument was used in the form of a description test and questionnaire. From the results of this study, it was concluded that the mathematical critical thinking ability that gets the PBL model is better than the DL model.Kemampuan berpikir kritis masih belum maksimal, hal ini dikarenakan pembelajaran yang belum optimal. Oleh karena itu di perlukan sebuah variasi proses pembelajaran baik pendekatan, metode, atau model pembelajaran yang inovatif untuk dapat meningkatkan kemampuan berpikir kritis matematis. Model pembelajaran yang mendukung meningkatkan kemampuan berpikir kritis matematis adalah model PBL dan DL. Adapun tujuan dari penelitian ini adalah untuk mengetahui kemampuan berpikir kritis matematis siswa yang mendapatkan model PBL lebih baik daripada model DL. Metode penelitian yang digunakan adalah kuasi eksperimen dengan populasi seluruh siswa kelas XI SMA Negeri 11 Garut. Karena pengambilan sampel purpose sampling maka sampel yang diambil sebanyak dua kelas yaitu kelas XI MIPA 5 sebagai kelas eksperimen I yang mendapatkan model PBL dan kelas XI MIPA 8 sebagai kelas eksperimen II yang mendapatkan model DL. Instrumen penelitian yang digunakan berupa tes uraian dan angket. Berdasarkan hasil analisis secara statistik diperoleh kesimpulan bahwa kemampuan berpikir kritis matematis yang mendapatkan model PBL lebih baik dari pada model DL.

“…Berpikir logis atau disebut juga penalaran mempunyai fungsi yang sangat penting dalam upaya peningkatan pembelajaran dan hasil pembelajaran Matematika (Iswara, Darhim, & Juandi, 2021;Pratama & Mardiani, 2022). Karena, dalam memecahkan masalah Matematika, diperlukan pemikiran yang jelas dan terarah untuk mendapatkan hasil yang maksimal, dimana berpikir kritis dijadikan dasar untuk memunculkan gagasan terhadap tiap makna untuk mengembangkan berpikir secara logis (Lusiana, Armiati, & Yerizon, 2022).…”

Penelitian ini bertujuan untuk mengetahui pengaruh problem-based learning terhadap kemampuan penalaran matematik, dan korelasi kemampuan penalaran matematik dengan kemampuan awal siswa SMP. Populasi dalam penelitian ini adalah seluruh siswa SMP Negeri 1 Tanjung Palas Tengah, sampelnya diambil dua kelas secara random dari seluruh kelas VIII. Metode yang digunakan yaitu metode eksperimen, dimana instrumennya terdiri dari pretest dan postest. Hasil penelitian menunjukkan bahwa pada data pretest tidak menunjukkan adanya perbedaan kemampuan penalaran matematika antara kelompok kontrol dan kelompok eksperimen. Hasil uji t pada data postest menunjukkan perbedaan kemampuan penalaran matematika antara kelompok eksperimen dan kelompok kontrol pada taraf signifikansi 5%. Pada uji korelasi Widespread Biserial menunjukkan adanya korelasi. Disimpulkan bahwa terdapat pengaruh problem-based learning terhadap peningkatan kemampuan penalaran matematik siswa dan kemampuan awal siswa tidak membedakan peningkatan kemampuan penalaran matematika siswa dan korelasinya.This study aims to determine the effect of problem-based learning on mathematical reasoning abilities, and the correlation of mathematical reasoning abilities with the initial abilities of junior high school students. The population in this study were all students of SMP Negeri 1 Tanjung Palas Tengah, the samples were taken randomly from two classes of class VIII. The method used is the experimental method, where the instrument consists of a pretest and posttest. The results showed that the pretest data did not show any difference in mathematical reasoning ability between the control group and the experimental group. The results of the t-test on posttest data showed differences in mathematical reasoning abilities between the experimental group and the control group at a significance level of 5%. The Biserial Widespread correlation test shows a correlation. It was concluded that there was an effect of problem-based learning on increasing students' mathematical reasoning abilities and students' initial abilities did not distinguish between increasing students' mathematical reasoning abilities and their correlations.

“…This era is known as the era of globalization or the 21st century. This era is synonymous with the use of technology in all aspects of human life (Iswara et al, 2021;Shahroom & Hussin, 2018;Sobandi et al, 2021). One of them is education, in this aspect, it requires the use of technology as a learning medium.…”

There are lots of schools in Indonesia still use conventional learning method in learning process. That is still using the book as a medium of learning. Learning media used in the 4.0 era is still minimal and rarely uses technology as a learning medium. Gamification can be used as an alternative learning media that can make the learning process more effective, engaging, and fun. This research aims to develop learning media in the form of game for elementary school students' in learning English. This study uses a design and development (D&D) methodology and the ADDIE model. The research subject is the fourth-grade elementary school students. The instrument used was a questionnaire and observations. And the data analysis used is descriptive qualitative and descriptive quantitative. The resulting data are in the form of (1) the design and development results using the ADDIE method (analysis, design, development, implementation, and evaluation). (2) To obtain product validity and effectiveness results from expert judgment, teacher, and product trial to students. From the results of expert judgment, very valid results were obtained. And the students' results are very valid, and several things need to be revised again to perfect the product
