PENGARUH MODEL PROBLEM BASED LEARNING BERBANTUAN MEDIA PADUDI TERHADAP MOTIVASI BELAJAR MATEMATIKA KELAS V SD

Abstract

Learning motivation is an important factor influencing students’ engagement in mathematics learning. Based on interviews with a fifth-grade teacher, students’ enthusiasm for mathematics learning was not consistently maintained, particularly when learning to present data using bar charts. This condition was associated with learning activities that were predominantly focused on teacher explanations, textbook use, and routine exercises, resulting in limited variation in students’ learning experiences. This study aimed to analyze the effect of the Problem-Based Learning (PBL) model assisted by PADUDI media on the mathematics learning motivation of fifth-grade elementary school students. A quantitative approach with a quasi-experimental method and a Nonequivalent Control Group Design was employed. The participants consisted of 53 fifth-grade students at SDN Percobaan 1 Kota Malang, including 26 students in the experimental group and 27 students in the control group. Data were collected through a learning motivation questionnaire, observation, and documentation. The data were analyzed using descriptive statistics, a paired-samples t-test, and an independent-samples t-test after meeting the normality and homogeneity assumptions. The results showed that the mean motivation score in the experimental group increased from 68.46 in the pretest to 86.96 in the posttest, whereas the control group increased from 67.74 to 74.00. The independent-samples t-test yielded t = 17.260 with p < 0.001. Therefore, the implementation of PBL assisted by PADUDI media had a significant effect on students’ mathematics learning motivation. These findings indicate that combining a problem-based learning model with concrete instructional media can serve as an alternative approach for creating more active and contextual mathematics learning while strengthening students’ learning motivation.

ABSTRAK

Motivasi belajar merupakan salah satu faktor penting yang memengaruhi keterlibatan murid dalam pembelajaran matematika. Berdasarkan hasil wawancara dengan guru kelas V, antusiasme murid dalam pembelajaran matematika belum konsisten, khususnya pada materi penyajian data dalam bentuk diagram batang. Kondisi tersebut berkaitan dengan pembelajaran yang masih didominasi penjelasan guru, penggunaan buku paket, dan latihan soal sehingga pengalaman belajar murid kurang variatif. Penelitian ini bertujuan menganalisis pengaruh model Problem-Based Learning (PBL) berbantuan media PADUDI terhadap motivasi belajar matematika murid kelas V sekolah dasar. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain Nonequivalent Control Group Design. Sampel penelitian terdiri atas 53 murid kelas V SDN Percobaan 1 Kota Malang, yaitu 26 murid pada kelas eksperimen dan 27 murid pada kelas kontrol. Data dikumpulkan melalui angket motivasi belajar, observasi, dan dokumentasi. Data dianalisis menggunakan statistik deskriptif serta uji paired samples t-test dan independent samples t-test setelah memenuhi uji normalitas dan homogenitas. Hasil penelitian menunjukkan bahwa rata-rata motivasi belajar kelas eksperimen meningkat dari 68,46 pada pretest menjadi 86,96 pada posttest, sedangkan kelas kontrol meningkat dari 67,74 menjadi 74,00. Hasil independent samples t-test menunjukkan nilai t = 17,260 dengan p < 0,001. Dengan demikian, penerapan model PBL berbantuan media PADUDI berpengaruh signifikan terhadap motivasi belajar matematika murid kelas V. Temuan ini menunjukkan bahwa kombinasi model pembelajaran berbasis masalah dan media konkret dapat menjadi alternatif untuk menciptakan pembelajaran matematika yang lebih aktif, kontekstual, dan mendorong motivasi belajar murid.
