Abstract

Material relations and functions load understanding concept on lesson mathematics as well as can help student For finish question mathematics with good and right. Objective study This is For analyze error student in finish question relations and functions based on theory Castle ie error conceptual, error procedural and error technique as well as reason happening error the. subject study are 18 students class VIII SMPN 13 Dumai. Data collection techniques are carried out with test and interview. Instrument test used is test written from valid questions and guidelines interview For verify reason student in answer question the. Obtained data from results test, then analyzed with use method descriptive qualitative. Analysis results shows 33% students do error conceptual, 41% students do error procedural, and as many as 26% students do error technical. As for what causes students are wrong finish question Relations and functions including : 1) less understand cause issue student Confused finish the answer ; 2) no control rule calculation algebra ; 3) rush in finish question so that lots wrong calculation.

Abstract

This study identified the numeracy literacy skills of Almuttaqin MTS students in a rigid material. A hallmark of numeracy literacy is the capacity to apply numbers and related symbols to operations on algebraic forms, analyze data, and understand analysis findings to predict and make judgments. Tests and interviews were used to collect data, which were then analyzed through data reduction, presentation, and conclusion. Based on the findings, the numeracy literacy skills of MTS Almuttaqin students, one student (4%) is included in the excellent group for numeracy literacy, nine students (34%) are included in the excellent category, 15 students (50%) are included in the good category, and five students (11)% is included in the less category. Students with high numeracy literacy (ST) can use various numbers and symbols to solve problems, analyze information to make predictions, evaluate the findings of their analysis, and make decisions when handling the challenges of the given material. Using various numbers and symbols to solve problems and analyze information is the only marker that satisfies students with moderate numeracy literacy (SD). They have not yet reached the stage where they can make the best choices regarding their assigned content. Students with limited numeracy literacy (SR) only write numbers and are identified when completing assignments. As a result, SD and SR have not fully learned numeracy skills. The indications that were not fulfilled were caused by mistakes made by students, including not carefully recording known and asked data, choosing an inappropriate problem-solving approach, and not understanding ideas well enough to answer questions problem.

Abstract

Tujuan: Penelitian ini bertujuan untuk mendeskripsikan pengaruh pembelajaran dengan bahan ajar Realistic Mathematics Education (RME) terhadap peningkatan kemampuan pemahaman matematis (KPM) murid kelas VII pada materi Aritmetika Sosial di SMPS IT Mutiara Duri Bengkalis. Metode: Penelitian ini merupakan eksperimen semu dengan desain Nonequivalent Pretest-Posttest Control Group Design. Sampel penelitian terdiri atas dua kelas yang dipilih menggunakan teknik purposive sampling berdasarkan kesamaan kemampuan awal matematis (KAM). Kelas eksperimen mengikuti pembelajaran dengan bahan ajar RME, sedangkan kelas kontrol mengikuti pembelajaran dengan buku paket yang biasa digunakan di sekolah. Data penelitian diperoleh melalui dokumentasi nilai Sumatif Akhir Semester untuk melihat KAM serta tes pretest-posttest KPM, kemudian dianalisis menggunakan uji Independent Sample T-Test.  Hasil: Hasil penelitian menunjukkan bahwa terdapat perbedaan KPM antara murid yang mengikuti pembelajaran dengan bahan ajar RME dan murid yang mengikuti pembelajaran dengan buku paket yang biasa digunakan di sekolah, dengan nilai signifikansi kurang dari 0,05. Rata-rata peningkatan KPM murid kelas eksperimen juga lebih tinggi secara signifikan dibandingkan kelas kontrol. Rata-rata skor N-gain kelas eksperimen sebesar 0,7193 berada pada kategori tinggi, sedangkan kelas kontrol sebesar 0,3540 berada pada kategori sedang. Simpulan: Pembelajaran dengan bahan ajar Realistic Mathematics Education (RME) berpengaruh terhadap peningkatan KPM murid. Oleh karena itu, pembelajaran dengan bahan ajar RME dapat dijadikan alternatif untuk membantu meningkatkan KPM murid pada materi Aritmetika Sosial.
