Speaking is a productive skill that the students should master but in practice the researcher found that seventh-grade students at SMPN 10 Tarakan still struggled with English speaking skills due to limited opportunities to practice in meaningful contexts. The purpose of this study was to examine the effect of Situational Language Teaching (SLT) on students' speaking skills using a Quasi-Experimental pre-test-post-test Control and Experiment group design at SMPN 10 Tarakan, involving 26 students in the Experimental class and 27 in the Control class. The Experimental class was taught using SLT over four sessions (introducing oneself and others, hobbies, describing people, and daily activities), while the Control class received Teacher-Centered Instruction. Speaking skills were measured through pre-tests and post-tests covering pronunciation, grammar, vocabulary, fluency, and comprehension, and it was analysed using descriptive statistics, normality and homogeneity tests, independent and paired samples t-tests, N-Gain, and Cohen's d. Both classes had equivalent initial proficiency ( t = 1.097 df = 51 p = 0.278 ) and showed significant improvement from pre-test to post-test (p 0.001) The Experimental class demonstrated greater improvement (31.08 Gain = 0.45) compared to the Control class (23.26 points; N-Gain = 0.35), with both falling into the moderate category. Following the intervention, the Experimental class achieved significantly higher scores ( t = 3.197 ; df = 51 P = 0.002 ) with a large effect size (d = 0.88) These findings indicated that the students which were taught using SLT experienced greater improvement in speaking skills compared to those taught using Teacher-Centered Instruction. English teachers are encouraged to optimize time allocation and utilize engaging instructional media by integrating technology.

Kemampuan numerasi berperan penting untuk membantu murid dalam memahami dan menafsirkan informasi melalui konsep matematika. Penelitian ini bertujuan untuk menguji pengaruh model pembelajaran Read Outline Discussion Evaluation (RODE) terhadap kemampuan numerasi murid kelas XII. Penelitian ini menggunakan desain quasi experiment bentuk non -equivalent control group design yang melibatkan dua kelas dengan masing-masing 30 murid sebagai kelas eksperimen dan kelas kontrol. Kelas eksperimen diberikan perlakuan menggunakan model RODE, sedangkan kelas kontrol menggunakan metode konvensional (ceramah). Data dikumpulkan melalui pretest dan posttest berupa soal uraian indikator kemampuan numerasi, kemudian dianalisis menggunakan uji Mann-Whitney U karena tidak semua data berdistribusi normal. Hasil analisis menunjukkan adanya perbedaan yang signifikan antara kedua kelas dengan nilai signifikansi 0,024 0,05. Selain itu, rata-rata N-Gain pada kelas eksperimen (0,56) lebih tinggi daripada kelas kontrol (0,41). Dengan demikian, model pembelajaran RODE terbukti berpengaruh positif terhadap peningkatan kemampuan numerasi murid. Model ini dapat dijadikan alternatif inovatif dalam pembelajaran matematika untuk mendukung literasi dan numerasi di sekolah.

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning (PBL) terhadap keterampilan berpikir kritis matematis siswa di kelas VIII SMPN 2 Pulau Bunyu. Penelitian ini menggunakan Quasi Eksperimen. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMPN 2 Pulau Bunyu tahun ajaran 2024/2025. Teknik pengambilan sampel dilakukan dengan teknik sampling jenuh sehingga diperoleh sampel pada penelitian ini 63 siswa yaitu 32 siswa kelas VIII-A sebagai kelas kontrol dan 31 siswa kelas VIII-B sebagai kelas eksperimen. Pengumpulan data keterampilan berpikir kritis matematis menggunakan tes yaitu pretest dan posttest yang masing-masing terdiri dari 5 soal uraian dengan soal yang berbeda. Data penelitian dianalisis dengan teknik analisis deskriptif, uji Independent Sample T-Test dan uji N-Gain Score. Hasil penelitian menunjukkan bahwa terdapat pengaruh model pembelajaran Problem Based Learning (PBL) terhadap keterampilan berpikir kritis matematis siswa di kelas VIII SMPN 2 Pulau Bunyu, hal ini sesuai dengan hasil perhitungan uji Independent Sample T-Test diperoleh nilai 𝑡 ℎ𝑖𝑡𝑢𝑛𝑔 : 1,950 > 𝑡 𝑡𝑎𝑏𝑒𝑙 : 1,67022 pada taraf signifikansi 5%. Kemudian dilakukan uji lanjut menggunakan uji N-Gain Score diperoleh nilai rata-rata untuk kelas eksperimen sebesar 0,58 lebih tinggi dibandingkan nilai rata-rata untuk kelas kontrol sebesar 0, 32. Hasil ini diperkuat dengan nilai rata-rata hasil tes keterampilan berpikir kritis matematis pada kelas yang menerapkan model pembelajaran Problem Based Learning (PBL) lebih tinggi dibandingkan dengan rata-rata hasil tes keterampilan berpikir kritis matematis pada kelas yang menerapkan model pembelajaran konvensional. Dengan demikian disimpulkan bahwa terdapat pengaruh model pembelajaran Problem Based Learning (PBL) terhadap keterampilan berpikir kritis matematis siswa di kelas VIII SMPN 2 Pulau Bunyu. This study examines the impact of the Problem-Based Learning (PBL) model on students' mathematical reasoning and critical thinking skills in eighth grade at SMPN 2 Pulau Bunyu. A quasi-experimental design was employed, with the population comprising all eighth-grade students at SMPN 2 Pulau Bunyu in the 2024/2025 academic year. A total sampling technique was used, resulting in a sample of 63 students, consisting of 32 students in class VIII-A as the control group and 31 students in class VIII-B as the experimental group. Data were collected through preliminary and final assessments comprising five open-ended mathematical problems. The data were analyzed using descriptive statistics, an independent sample t-test, and an N-gain score test. The results indicate that the PBL model significantly affected students' mathematical reasoning and critical thinking skills. The independent sample t-test showed a statistically significant difference between the experimental and control groups (t = 1.950, p 0.05). Additionally, the N-gain score analysis revealed that the experimental group (0.58) outperformed the control group (0.32), indicating a moderate improvement in mathematical reasoning. Furthermore, students in the PBL-based classroom consistently demonstrated higher post-test scores than those taught using conventional instructional methods. These findings suggest that Problem-Based Learning (PBL) is a practical pedagogical approach for fostering students' mathematical reasoning, problem-solving abilities, and critical thinking skills in secondary education.
