Implementasi PMRI Dalam Materi Sifat Komutatif Dan Assosiatif Pada Bilangan Bulat Untuk Level Siswa SD/MI
Full text linkImplementing PMRI in teaching process using a little sheet box and straw as a media for helping students in learning commutative and associative properties in integer numbers is the aim of this study. Design research is used as appropriate means to achieve the aim; conducted in three phases: preliminary design, teaching experiment (first and second cycle), and retrospective analysis. This study enables students to work with contextual situations within integer numbers of properties; uses media tool (a straw and little sheet box). Pendidikan Matematika Realistik Indonesia (PMRI) underlies the design of the context and the activities. Sample of population is students from Madrasah Ibtidaiah Negeri 1 Palembang. This study involves fourth grade students, 3 students in first cycle and 36 students in second cycle (4 students were analyzed in detail). The result of this study could show that the activities could bring students’ learning from the contextual situation to more formal situation. The activities within this study have been succeeded to be implemented in this school so that these activities could be used for the others
Meningkatkan Kemampuan Siswa Dalam Pemecahan Masalah Matematik Melalui Pendekatan Metakognitif
Full text linkPenelitian eksperimen ini bertujuan untuk mengetahui peningkatan dan membandingkan kemampuan pemecahan masalah matematik pada kelompok siswa yang pembelajarannya menerapkan pendekatan metakognitif (PM) dan pendekatan konvensional (PK). Instrumen yang digunakan berupa tes kemampuan pemecahan masalah matematik. Analisis data dilakukan dengan uji gain ternormalisasi dan uji perbedaan dua rata-rata. Hasil utama dari penelitian ini adalah secara keseluruhan siswa yang pembelajarannya dengan PM (kelompok eksperimen) peningkatan kemampuan pemecahan masalah matematiknya termasuk tinggi dan secara signifikan lebih baik dibandingkan dengan siswa yang pembelajarannya dengan PK (kelompok kontrol)
Upaya Meningkatkan Kemampuan Komunikasi Statistika Melalui Pemberian Praktikum Pengolahan Data Berbantuan Komputer Pada Mahasiswa Prodi Pendidikan Matematika Stkip Garut
Full text linkIn general students assume that statistics is scary enough course because the material requires a lot of counting. The purpose of this research is to compare Statistical communication ability between students who received MS Excel with students who received SPSS. The research method is experiment method by taking two classes as research samples. The first experiment class received MS Excel and the second experiment class received SPSS. The research materials include two test average of the dependent samples, two test average of independent samples, one way ANOVA test, regression, and simple correlation. The research results by using independent t-test, one way ANOVA, two-way ANOVA, as well as further Post Hoc test using Tukey HSD test with significant level of 0.05 conclude that: 1) Statistical communication ability of students who got MS Excel was better than those who got SPSS. 2) The increase in statistical communication ability of students who got MS Excel is better than those who got SPSS. 3) The increasing achievement of statistical communication, based on students\u27 early capability (low, average, high), of those students who got MS Excel was better than those who got SPSS for the students who have low and average level. For students who have high level there was no significant difference in students who got MS Excel than those who got SPSS. 4) There was no interactive influence between learning model given and students early capability toward statistical communication ability
