Abstract

The purpose of this class action research is to define the implementation of the problem based learning model to improve the mathematical reasoning ability of the students of the eighth grade Fatimah Azzahra SMP IT Izzudin Palembang 2023/2024 on circular material. Execution of research using two cycles, each cycle has steps namely planning, action, observation, and reflection. Data collection on this study uses observation, and testing. The research was carried out with the participation of 17 students of the eighth grade at Izzudin Palembang IT High School. The aim of this study is to apply the learning model of problem based learning with the aim of improving the ability of mathematical reasoning of students. Students experience improvement in every aspect. The increase in the percentage of students' scores in mathematical reasoning skills during the first cycle reached 61.91%, while in the second cycle increased by 84.03%. The implementation of this study uses the pre-cycle phase by giving pre-test questions so that students reached the percent of 43.13% and in the post-test phase students achieved 80.84% so that it can be concluded that each indicator of mathematic reasoning ability students experienced a good improvement.

Abstract

Penelitian ini ialah penelitian tindakan kelas yang bertujuan untuk meningkatkan kemampuan pemecahan masalah peserta didik kelas VIII Halimah Binti Abi Dzuaib SMP IT Izzudin Palembang melalui penerapan model Problem Based Learning (PBL). Penelitian ini memuat dua siklus dengan tiap siklus mencakup empat tahap yakni rencana, tindakan, pengamatan, dan refleksi. Peserta didik kelas VIII Halimah Binti Abi Dzuaib yang berjumlah 20 orang adalah subjek dari penelitian ini. Analisis data secara kualitatif yakni dengan mencari nilai rerata kelas guna melihat ketercapaian tujuan pembelajaran dan mencari persentase kemunculan indikator kemampuan pemecahan masalah. Hasilnya menunjukkan bahwa saat diterapkannya model problem based learning, nilai akhir rerata peserta didik yaitu 83,20 yangmana sudah memenuhi KKTP yang sudah ditentukan dan pada setiap indikator kemampuan pemecahan masalah meningkat hingga siklus 2. Sesuai dengan hasil tersebut dapat ditarik kesimpulan bahwasanya model problem based learning efektif mampu meningkatkan kemampuan pemecahan masalah peserta didik kelas VIII Halimah Binti Abi Dzuaib SMP IT Izzudin Palembang pada materi lingkaran.
