Abstract

This research is motivated by the not yet optimal application of differentiated learning where teachers have not accommodated students' learning needs, in the form of learning readiness, learning interest and student learning profile (style). This study aims to improve student learning activities and outcomes. Data collection techniques using instruments: (1) student activity observation sheets, and (2) learning achievement tests. Data were analyzed with descriptive statistical analysis and descriptive analysis. The results showed that: The average percentage of completeness of student learning outcomes in cycle I was 92%, increasing to 96% in cycle II. While the percentage of student learning activities in cycle I reached 90.25%, an increase of 92% in cycle II. From the results of the study it can be concluded that the application of differentiated learning through the Problem Based Learning learning model can optimize student learning activities and outcomes.

Abstract

Social arithmetic is one of the mathematics learning materials that is very important and close to students' lives. This material is often considered easy, but in fact, students often face difficulties in understanding social arithmetic, especially in profit/loss material. With this condition, we must be able to compile a learning that is fun, interesting and directly involved in learning, including by using the PMRI approach. The research method used in this study is design research type validation studies, which consists of 3 stages, namely preparation and design, design experiment and retrospective analysis. This study formulates the Hypothetical Learning Trajectory (HLT) into 4 (four) activities, namely: (1) product design activities to determine the purchase price; (2) the activity of making products to determine the selling price; (3) the activity of selling products to determine profit/loss; (4) mathematical problem solving activities regarding profit/loss. The data collection technique in this study uses observation, voice recordings and LAS then analyzed descriptively, which is seen from the results of observations in the classroom, namely comparing HLT and the learning activity process. The result of this study is that the learning trajectory designed to increase the understanding of in-depth concepts about social arithmetic is in accordance with the characteristics of PMR learning, namely the use of context, the use of models, student engagement, interactivity and connection with other learning materials.

Abstract

Pemecahan masalah adalah upaya menemukan penyelesaian terhadap kesulitan yang tidak langsung bisa di dapatkan atau cara berpikir dengan langkah-langkah berurutan. Hasil raport pendidikan SMPN 4 Lalan menunjukkan bahwa kemampuan pemecahan masalah siswa dalam berpikir menggunakan konsep, prosedur, fakta, dan alat matematika untuk menyelesaikan masalah sehari-hari dengan berbagai jenis konteks yang relevan berada pada predikat sedang, yaitu persentase 64,44%. Tujuan penelitian adalah untuk mengetahui efektivitas pembelajaran menggunakan konteks makanan tradisional Musi Banyuasin terhadap kemampuan pemecahan masalah siswa. Jenis penelitian ini adalah desain pra-experimental dengan menggunakan model desain satu kelompok pretest/posttest. Metode pengumpulan data pada penelitian ini berupa observasi dan pretest/postest. Data yang didapatkan dikumpulkan dan di analisis secara deskriptif dan uji N-Gain untuk melihat efektivitas pembelajaran berbasis pemecahan masalah menggunakan konteks makanan tradisional Muba “Kecepan Tungkus”. Berdasarkan analisis data diperoleh bahwa hasil observasi menunjukkan secara keseluruhan nilai aktivitas siswa berada pada kriteria minimal baik, yaitu dengan persentase aktivitas siwa di atas 70%. Sedangkan hasil mean pretest/posttest siswa mengalami peningkatan sebesar 54 dengan mean N-Gain sebesar 0,58 dan termasuk kategori sedang. Maka kesimpulannya bahwa pembelajaran berbasis pemecahan masalah menggunakan konteks makanan tradisional Muba “Kecepan Tungkus” cukup efektif diterapkan dalam pembelajaran dengan persentase rata-rata keefektifan mencapai 58 %.
