Abstract

Purpose: Mathematics is a compulsory subject in education due to its extensive application in daily life. However, in reality, many students still face difficulties in understanding and learning mathematics. One of the key competencies in mathematics education that students need to master is mathematical communication skills. This study aims to analyze the effect of applying the constructivism approach on the mathematical communication skills of grade VIII students at SMP Negeri 1 Bayang Utara. Method: This study uses a quasi-experimental method with a randomized control group only design. The population in this study is all grade VIII students, and the sampling technique is carried out by saturated samples. The sample consisted of two classes, namely an experimental class that used a constructivist approach and a control class that used conventional learning methods. The research instrument is in the form of an essay test that measures students' mathematical communication skills. Findings: The results showed that the average mathematical communication ability of students in the experimental class (81.67) was higher than that of the control class (71.64). Statistical tests with t-tests showed that there was a significant difference between the two groups at a real level of α = 0.05. This proves that the constructivism approach has a significant positive influence on students' mathematical communication skills. Significance: The results of this study show that the constructivist approach enhances students' mathematical communication skills by encouraging active knowledge construction through interaction and exploration. This helps students convey mathematical ideas more effectively, improving their ability to explain problems clearly and logically. These findings imply that the constructivist approach can support the improvement of mathematical learning outcomes, particularly in communication skills, which are essential for developing critical thinking and problem-solving abilities.

Abstract

Literasi matematis adalah kemampuan yang esensial bagi generasi saat ini dan mendatang. Namun, berdasarkan PISA 2018, PISA 2022, dan hasil observasi di SMAN 1 Padang dan SMAN 10 Padang, kemampuan literasi matematis peserta didik masih rendah. Penelitian ini bertujuan untuk mengembangkan bahan ajar berupa e-modul berbasis Problem Based Learning, dengan harapan dapat meningkatkan kemampuan literasi matematis peserta didik kelas XI SMA. Hasil penilaian awal dan literatur menunjukkan bahwa tingkat literasi matematis peserta didik masih tergolong rendah. Hal ini disebabkan oleh kurangnya pengalaman dengan pemecahan masalah berbasis literasi serta ketiadaan bahan ajar yang sesuai. Penelitian ini menggunakan metode penelitian pengembangan dengan Model Plomp yang meliputi tiga fase: penelitian pendahuluan, pengembangan atau pembuatan prototipe, dan tahap evaluasi. Kualitas produk yang dikembangkan dievaluasi berdasarkan kriteria yang diusulkan oleh Nieveen, yaitu kevalidan, kepraktisan, dan keefektifan. Pengumpulan data dilakukan dengan menggunakan berbagai instrumen yang meliputi lembar validasi, angket, lembar observasi, pedoman wawancara, dan tes. Berdasarkan penilaian para ahli, e-modul berbasis Problem Based Learning memenuhi kategori sangat valid. Aspek kepraktisan mencapai kategori sangat praktis ditinjau dari observasi keterlaksanaan e-modul berbasis Problem Based Learning, angket respon peserta didik, dan angket respon pendidik. Selanjutnya efektifitas e-modul berbasis Problem Based Learning dalam meningkatkan kemampuan literasi matematis mencapai kriteria sangat efektif, yang ditunjukkan dari hasil tes literasi matematis dengan rata-rata pencapaian indikator di atas 60% dan tingkat ketuntasan belajar peserta didik lebih dari 70% pada tahap field test. Implikasinya, e-modul berbasis PBL efektif mendukung literasi matematis dan layak diterapkan lebih luas di sekolah menengah.
