Abstract

This study aims to compare the effectiveness of the RODE and PBL learning models in improving students’ mathematical communication skills. The study employed a quasi-experimental nonequivalent-group pretest-posttest design involving two experimental groups. The research sample consisted of 44 eighth-grade students of MTs Al-Imam Asy-Syafi’i in Tarakan, North Kalimantan, Indonesia. The students were divided into two groups: Experimental group 1 was taught using the RODE model, and experimental group 2 was taught using the PBL model. Data were collected through pretests and posttests in the form of three essay questions measuring the indicators of written text, drawing, and mathematical expression. The normality test indicated that the N-Gain data were not normally distributed; therefore, inferential analysis was conducted using the Mann–Whitney U test. The results showed that the mean N-Gain of the RODE group (0.8290) was higher than that of the PBL group (0.6107). The Mann–Whitney U test showed a significant difference between the two groups (U = 157.50, Z = -2.07, p = 0.038), with the mean rank of the RODE group (26.34) higher than that of the PBL group (18.66). Thus, there was a significant difference in the improvement of students’ mathematical communication skills between the two learning models. These findings indicate that the RODE model is more effective than the PBL model in improving students’ mathematical communication skills, particularly on the topic of linear equations in one variable at MTs Al-Imam Asy-Syafi’i in Tarakan, North Kalimantan, Indonesia.

Abstract

This study aimed to investigate the effect of the Web Liveworksheet-Based SCCrT Model on students’ (1) creative thinking skills, (2) critical thinking skills, and (3) responses toward the implementation of the model in learning the basic laws of chemistry. The study employed a pre-experimental method using a one-group pretest-posttest design. The participants consisted of 35 students. Data were collected through creative and critical thinking tests and analyzed descriptively. The findings revealed that implementing the SCCrT Model improved students’ creative thinking skills, as indicated by an increase in the mean score from 23.44 to 71.70. In addition, students’ critical thinking skills also improved, with the mean score increasing from 32.71 to 71.14. Furthermore, students demonstrated good responses toward the implementation of the SCCrT model, with 74.51% expressing positive responses. These findings indicate that the SCCrT Model has the potential to improve students’ creative and critical thinking skills in learning the basic laws of chemistry topic.

Abstract

Pergaulan negatif di kalangan remaja sekolah menengah atas merupakan permasalahan sosial yang memerlukan intervensi preventif dan terstruktur. Siswa SMA Negeri 2 Tarakan menghadapi keterbatasan program preventif yang menyentuh aspek sosial-emosional, sementara layanan bimbingan dan konseling belum mampu menjangkau seluruh siswa secara merata. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan kesadaran siswa terhadap risiko pergaulan negatif sekaligus melatih kemampuan mereka dalam menyelesaikan masalah sosial secara kreatif dan konstruktif. Pendekatan yang digunakan adalah workshop partisipatif berbasis psikoedukatif yang menerapkan kerangka Creative Problem Solving, mencakup pemaparan materi, simulasi kasus dalam kelompok kecil, serta refleksi. Kegiatan dilaksanakan pada 11 Mei 2026 dan melibatkan 30 siswa dari kalangan pengurus OSIS dan perwakilan kelas. Hasil pengukuran menunjukkan peningkatan rerata skor dari 58,6 menjadi 75,8, melampaui ambang keberhasilan yang ditetapkan sebesar 20%. Selain itu, 90 hingga 97 persen peserta menyatakan bahwa kegiatan tersebut bermanfaat dan relevan. Kolaborasi sebelas dosen lintas program studi dari Universitas Borneo Tarakan memperkuat kualitas pendampingan dan menjadikan model ini berpotensi direplikasi di sekolah lain.

Abstract

This study aims to determine the influence of the Problem-Based Learning (PBL) learning model on students’ mathematical critical thinking skills in grade VIII of SMPN 2 Bunyu Island. This study uses a quasi-experiment, with a sample of 63 students obtained through saturated sampling. Data on mathematical critical thinking skills were collected with five different description questions for the pretest and posttest. The research data were analyzed using descriptive statistics, an independent-samples t-test, and an N-gain score test. The descriptive analysis showed that the average score on the mathematical critical thinking tests in the experimental class using the Problem-Based Learning (PBL) model was higher than that in the control class using the conventional model. The independent-samples t-test showed t-calculate > t-table at the 5% significance level, and the follow-up test using the N-gain score showed that the average score of the experimental class was significantly higher than the average N-gain score of the control class. Thus, it was concluded that the Problem-Based Learning (PBL) learning model influenced students’ mathematical critical thinking skills in grade VIII of SMPN 2 Bunyu Island. Implementing the Problem-Based Learning (PBL) model can be an effective strategy for improving students’ critical thinking skills in mathematics.   Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning (PBL) terhadap keterampilan berpikir kritis matematis siswa di kelas VIII SMPN 2 Pulau Bunyu. Penelitian ini menggunakan Quasi Eksperimen. Sampel penelitian ini berjumlah 63 siswa yang diperoleh melalui teknik sampling jenuh. Data keterampilan berpikir kritis matematis dikumpulkan dengan 5 soal uraian yang berbeda untuk pretest dan posttest. Data penelitian dianalisis dengan teknik analisis deskriptif, uji independent sample t-test dan uji N-gain score. Hasil analisis deskriptif menunjukkan skor rata-rata hasil tes keterampilan berpikir kritis matematis pada kelas eksperimen yang menerapkan model PBL lebih besar dibandingkan dengan kelas kontrol yang menerapkan model pembelajaran konvensional. Uji independent sample t-test menunjukkan nilai thitung > ttable pada taraf signifikansi  serta hasil uji lanjut menggunakan uji N-gain score diperoleh skor rata-rata N-gain kelas eksperimen lebih besar dibandingkan skor rata-rata N-gain kelas kontrol. Dengan demikian disimpulkan bahwa terdapat pengaruh model PBL terhadap keterampilan berpikir kritis matematis siswa di kelas VIII SMPN 2 Pulau Bunyu. Penerapan model PBL dapat menjadi strategi efektif untuk meningkatkan keterampilan berpikir kritis matematis siswa
