Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning terhadap kemampuan pemecahan masalah siswa pada pembelajaran matematika kelas X di SMA Bait Al-Quran Kayuagung Ogan Komering Ilir Sumatera Selatan. Metode penelitian yang digunakan adalah quasi eksperiment dengan rancangan non-equivalent control group design. Sampel penelitian ini adalah kelas X Palestina sebagai kelas eksperimen dan kelas X Yaman sebagai kelas kontrol. Sampel penelitian ini dipilih dengan teknik purposive sampling. Proses pembelajaran di kelas eksperimen mendapatkan perlakuan dengan model pembelajaran Problem Based Learning dan di kelas kontrol diajarkan dengan model pembelajaran konvensional. Pengumpulan data menggunakan teknik tes berbentuk soal essai berjumlah lima soal untuk mengukur kemampuan pemecahan masalah siswa. Berdasarkan uji hipotesis dengan menggunakan uji-t pada taraf signifikan (α) = 0,05. Berdasarkan analisis t-test data test akhir diperoleh nilai Sig. (2-tailed) sebesar 0,00 < 0,05 kemudian menurut basis pengambilan keputusan dalam T-Test dapat disimpulkan H0 ditolak dan Ha diterima. Dengan demikian hipotesis yang diajukan dalam penelitian ini terbukti, bahwa ada pengaruh yang signifikan model PBL pada kemampuan pemecahan masalah matematika siswa kelas X SMA Bait Al-Quran Kayuagung.

Abstract

Penelitian ini bertujuan mengetahui pengaruh penerapan pendekatan kontekstual terhadap kemampuan penalaran dan komunikasi matematika siswa kelas X SMA Negeri 1 Tanjung Lubuk Kecamatan Tanjung Lubuk kabupaten Ogan Komering Ilir.  Penelitian ini merupakan penelitian eksperimen semu dengan populasi kelas X SMA Negeri 1 Tanjung Lubuk tahun ajaran 2015/2016. Sampel diambil dengan metode purposive random sampling. Dari 6 kelas yang ada dipilih 2 kelas secara random, sebagai kolompok kontrol dan eksperimen. Data diambil dengan menggunakan tes. Data dianalisis dengan t-tes. Hasil penelitian menunjukkan bahwa ada pengaruh positif penerapan pendekatan kontekstual terhadap kemampuan penalaran dan komunikasi matematika siswa kelas X SMA Negeri 1 Tanjung Lubuk. Ada perbedaan kemampuan penalaran dan komunikasi secara signifikan antara siswa yang belajar dengan pendekatan kontekstual dan yang belajar dengan pendekatan konvensional, sehingga pendekatan kontekstual dapat diimplementasikan dalam pembelajaran matematika di kelas.

Abstract

This study aims to determine the influence of realistic mathematics education (RME) model learning on the achievements of mathematics students in grade VII at SMP Ba'it Al-Quran Kayuagung school year 2019/2020. The research method is quasi experiment. The research samples are grade VII Cairo and class VII Mecca using the study population. The data is collected by written test which is essay test.  To analyze the data, a prerequisite test of normality and homogeneity was conducted and a hypothesis test was conducted, namely the t-test. The results showed that the final test score at 0.000 and t-count was greater than the t-table. In other words, H0 is rejected. which means realistic mathematics education (RME) approach affects the achievements of mathematics learning students of SMP Ba'it Al-Quran Kayuagung. In conclusion, there are differences in learning achievement between students who use realistic mathematics education approach and students who use Teacher Centered approach.

Abstract

Abstract The research aims to determine the effectiveness of Realistic Mathematics Education (RME) Model Learning of mathematics learning achievement in grade VII in SMP ba'it Al-Quran Kayuagung school year 2019/2020. This study was conducted at the Al-Quran Ba'it Junior High school year 2019/2020. This type of research is the research of pseudo experiments (quasi experiment). The sampling techniques in this study used simple random sampling techniques, the research sample was Cairo's class VII as an experimental class and the VII class of Mecca as the control class. Test instruments using this type of essay test.  Data analysis techniques with prerequisite test and hypothesis testing. Test prerequisite in the form of normality and homogenization test while the hypothesis test using parametric statistical analysis is Independent Sample T Test at the equivalent of α-significance = 0.05. The results showed that there were different learning outcomes among students who used the Realistic Mathematics approach. This is in the event of test analysis of Independent Samples T Test The value of the post test obtained significance 0.000 0.05, then H0 rejected. This means that the Realistic Mathematics Education (RME) approach is effective to improve the students’ mathematics learning achievement at SMP Ba’it Al-Quran  Kayuagung.Keyword: Learning approach, RME, Learning achievement

Abstract

This study aims to evaluate the content validity of geometry teaching materials designed for Grade VII junior high school students. These materials were developed using the Connecting, Organizing, Reflecting, and Extending (CORE) instructional model, supported by Wingeom software, to enhance students' conceptual understanding of geometry. To assess validity, expert validation was conducted using structured questionnaires. Six categories of experts participated: subject-matter experts, media experts, mathematicians, school mathematicians, language experts, and learning evaluation experts. Each category included five experts. The Content Validity Index (CVI) was employed to quantify the degree of agreement among experts regarding the relevance of the materials. The results showed high content validity across all expert groups. Specifically, the s-CVI values were 0.96 for media experts, 0.98 for subject-matter experts, 0.97 for mathematicians, 0.96 for school mathematicians, and similarly high scores for evaluation and language experts. These scores exceed the commonly accepted threshold for strong content validity (s-CVI ≥ 0.90). The high CVI values indicate that the geometry teaching materials are valid in terms of content, language, instructional design, and evaluation components. Consequently, the materials are appropriate for use in further research related to mathematics learning processes at the junior high school level.
