Abstract

Penelitian ini bertujuan menganalisis pengaruh Problem Based Learning (PBL) berbantuan media manipulatif terhadap kemampuan berpikir komputasi siswa sekolah dasar ditinjau dari disposisi matematis. Penelitian menggunakan metode eksperimen dengan desain posttest only control group dan rancangan treatment by level 2×2. Sampel penelitian adalah siswa kelas V sekolah dasar di Kecamatan Tamansari, Kabupaten Bogor yang dibagi ke dalam kelas eksperimen (PBL berbantuan media manipulatif) dan kelas kontrol (pembelajaran ekspositori). Data kemampuan berpikir komputasi diperoleh melalui tes uraian yang mengukur aspek dekomposisi, abstraksi, pengenalan pola, dan algoritma, sedangkan disposisi matematis diukur menggunakan angket. Analisis data dilakukan dengan statistik deskriptif dan analisis inferensial yang terdiri dari Two Way ANOVA dan dilanjutkan dengan Uji Post Hoc Tukey. Hasil penelitian menunjukkan bahwa: (1) kemampuan berpikir komputasi siswa yang belajar menggunakan PBL berbantuan media manipulatif lebih tinggi dibandingkan siswa yang belajar menggunakan model ekspositori; (2) terdapat interaksi antara model pembelajaran dan disposisi matematis terhadap kemampuan berpikir komputasi; (3) pada siswa dengan disposisi matematis tinggi, PBL berbantuan media manipulatif menghasilkan kemampuan berpikir komputasi yang lebih tinggi daripada model ekspositori; dan (4) pada siswa dengan disposisi matematis rendah, model ekspositori memberikan hasil kemampuan berpikir komputasi yang lebih tinggi dibandingkan PBL berbantuan media manipulatif. Temuan ini menunjukkan bahwa efektivitas model pembelajaran dipengaruhi oleh disposisi matematis siswa, sehingga pemilihan model pembelajaran perlu disesuaikan dengan karakteristik afektif peserta didik untuk mengoptimalkan kemampuan berpikir komputasi. ***** This study aimed to examine the effect of Problem-Based Learning (PBL) assisted by manipulative media on elementary school students' computational thinking skills in terms of their mathematical disposition. The study employed an experimental method using a posttest-only control group design with a 2 × 2 treatment-by-level design. The participants were fifth-grade students from elementary schools in Tamansari District, Bogor Regency, who were assigned to an experimental group (PBL assisted by manipulative media) and a control group (expository learning). Data on computational thinking skills were collected through an essay test measuring four components: decomposition, abstraction, pattern recognition, and algorithmic thinking, while mathematical disposition was measured using a questionnaire. Data were analyzed using descriptive statistics and inferential statistics, including a Two-Way ANOVA followed by Tukey's Post Hoc test. The findings revealed that: (1) students taught through PBL assisted by manipulative media demonstrated significantly higher computational thinking skills than those taught through the expository model; (2) there was a significant interaction between the learning model and mathematical disposition on computational thinking skills; (3) among students with high mathematical disposition, PBL assisted by manipulative media resulted in higher computational thinking skills than the expository model; and (4) among students with low mathematical disposition, the expository model produced higher computational thinking skills than PBL assisted by manipulative media. These findings indicate that the effectiveness of a learning model is influenced by students' mathematical disposition. Therefore, the selection of instructional models should consider students' affective characteristics to optimize the development of computational thinking skills.
