Abstract

Critical thinking skills are essential competencies in mathematics education, enabling students to analyze problems, evaluate information, and construct logical arguments. However, students’ critical thinking abilities are often underdeveloped due to the dominance of teacher-centered instructional practices. This study aims to examine the effectiveness of the Project-Based Learning (PjBL) model in enhancing students’ critical thinking skills in mathematics at SMP Negeri 29 Makassar. This research employed a quantitative approach using a quasi-experimental design with a one-group pretest–posttest model. The participants consisted of 32 students. Data were collected through a critical thinking test administered before and after the implementation of the PjBL model. The data were analyzed using descriptive statistics, normality and homogeneity tests, paired sample t-test, and N-Gain analysis. The results revealed a significant improvement in students’ critical thinking skills. The mean score increased from 62.34 in the pretest to 84.12 in the posttest. The paired sample t-test showed a statistically significant difference (p < 0.05), indicating the effectiveness of the intervention. Furthermore, the N-Gain value of 0.58 was categorized as moderate, suggesting a meaningful level of improvement. These findings indicate that the implementation of the Project-Based Learning model effectively enhances students’ critical thinking skills by promoting active engagement, collaboration, and reflective learning. Therefore, PjBL can be considered a suitable instructional approach for fostering higher-order thinking skills in mathematics education.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman konsep perbandingan senilai siswa melalui pemanfaatan media katrol pasir edukatif berbasis STEAM. Kegiatan dilaksanakan pada 25 siswa kelas VII SMP Nastution Kartika XX-1 Makassar melalui tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Pendampingan dilakukan dengan menggunakan LKPD, observasi, wawancara, dan dokumentasi untuk melihat perkembangan pemahaman siswa. Hasil kegiatan menunjukkan bahwa penggunaan media berbasis STEAM mampu menciptakan pembelajaran yang lebih konkret, kontekstual, dan interaktif. Siswa menunjukkan peningkatan keterlibatan aktif dalam proses belajar, dengan variasi capaian berdasarkan tingkat kemampuan. Secara umum, kegiatan ini memberikan dampak positif terhadap pemahaman konsep matematika serta meningkatkan minat belajar siswa. Dengan demikian, media katrol pasir edukatif berbasis STEAM dapat menjadi alternatif inovatif dalam mendukung pembelajaran matematika yang lebih bermakna dan aplikatif di sekolah.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan meningkatkan aktivitas belajar siswa kelas VIII SMP Kartika XX-1 Makassar pada materi peluang melalui implementasi model Contextual Teaching and Learning (CTL) berbasis STEAM. Masalah utama mitra adalah pembelajaran yang abstrak dan minimnya penggunaan media interaktif. Metode pelaksanaan meliputi tiga tahap: perancangan perangkat pembelajaran, implementasi pembelajaran langsung di kelas oleh tim pengabdi, serta evaluasi aktivitas belajar. Tim pengabdi berperan sebagai fasilitator yang menghadirkan pengalaman belajar konkret menggunakan media "Roda Peluang". Hasil kegiatan menunjukkan peningkatan aktivitas belajar yang signifikan dengan rata-rata keterlibatan mencapai 86,6% (Sangat Aktif). Siswa mampu membangun pemahaman konsep peluang melalui eksplorasi empiris secara kolaboratif. Penerapan model CTL berbasis STEAM dengan bantuan media Roda Peluang efektif menciptakan ekosistem pembelajaran yang aktif, kreatif, dan menyenangkan bagi siswa.
