Abstract

This research was conducted to improve the mathematical literacy of fourth grade students. The purpose of this development research is to describe the steps of media development, media validity, practicality, and media effectiveness. The development method used is the ADDIE development model. The results showed that the media that had been developed were effective for improving students' mathematical literacy. This is evidenced from the results of material validation obtained a score of 69.33% in the category quite feasible and the results of media validation obtained a score of 97.33% in the category very feasible. Practicality results seen from the response of students get a score of 82% with a good category and a teacher response of 94% with a good category. Effectiveness results through the t test obtained a sig value. 0.000 and the average pretest result of 46.5 and the average posttest result of 75. The results of the Ngain calculation to see the effectiveness of the media obtained a value of 25.00 in the very high category. Thus, the results of the products that have been developed in the form of fractions worth domino cards can be categorized as good and suitable for use in the learning process.

Abstract

This study aims to analyze the influence of learning motivation, learning independence, executive function, and confidence on students' mathematical literacy skills. This research is a quantitative research. The research sample consisted of a number of high school students who were selected through random sampling techniques. Data were collected through questionnaires and mathematical literacy tests, then analyzed for path analysis to determine the contribution of each independent variable to the dependent variable. The results showed that there was a significant influence between learning motivation, learning independence, executive function, and confidence on students' mathematical literacy skills, both partially and simultaneously. There is an influence between learning motivation, learning independence, and self-confidence directly on executive function. Literacy ability is directly influenced by executive function and learning motivation significantly. Meanwhile, learning independence and self-confidence do not have a significant direct effect on mathematical literacy skills. However, learning independence and self-confidence affect mathematical literacy skills indirectly through executive functions. These findings show that strengthening psychological and cognitive factors is indispensable in improving students' mathematical literacy.

Abstract

Kemampuan pemecahan masalah matematis merupakan kompetensi fundamental dalam pembelajaran matematika di sekolah dasar, namun mayoritas siswa mengalami kesulitan signifikan dalam memahami konsep geometri. Penelitian ini bertujuan menganalisis efektivitas model Discovery Learning berbantuan media konkret geometri dalam meningkatkan kemampuan pemecahan masalah matematis siswa kelas II sekolah dasar pada materi bangun datar. Penelitian menggunakan metode eksperimen semu dengan desain Non-Equivalent Control Group Design yang melibatkan 35 siswa terbagi dalam kelompok eksperimen (21 siswa) dan kelompok kontrol (14 siswa). Data dikumpulkan melalui pretest dan posttest berbentuk esai yang mengukur kemampuan pemecahan masalah berdasarkan indikator Polya, kemudian dianalisis menggunakan statistik deskriptif dan Independent Samples t-test. Hasil penelitian menunjukkan perbedaan peningkatan yang sangat signifikan antara kedua kelompok (t = -17,304, p < 0,001). Kelompok eksperimen mencapai rata-rata N-Gain 0,79 (kategori tinggi) dengan ketuntasan klasikal 100%, sedangkan kelompok kontrol mencapai N-Gain 0,76. Discovery Learning berbantuan media konkret geometri terbukti lebih efektif dalam meningkatkan kemampuan pemecahan masalah matematis dibandingkan pembelajaran konvensional. Temuan ini menekankan pentingnya transformasi praktik pembelajaran menuju pendekatan berbasis eksplorasi dengan dukungan manipulatif konkret yang sesuai tahap perkembangan kognitif siswa sekolah dasar.
