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

 This classroom action research aims to determine whether the implementation of the Problem Based Learning (PBL) teaching model can enhance students' mathematical communication skills on the topic of two-dimensional shapes for eighth-grade students of Zaid Bin Tsabit Middle School IT Izzuddin Palembang in the second semester of the 2023/2024 academic year. The research was conducted in two cycles, encompassing four stages: planning, action, observation, and reflection. The subjects of this study were 20 students from the 8th-grade class Zaid Bin Tsabit. Data were obtained through a mathematical communication skills test. Based on the research and analysis conducted, it was found that the implementation of the Problem Based Learning (PBL) model has a positive impact on improving the mathematical communication skills of eighth-grade students of Zaid bin Tsabit Middle School IT Izzuddin Palembang in the second semester of the 2023/2024 academic year. This is evidenced by a significant improvement in mathematical communication skills between Cycle I and Cycle II. In the first cycle, the average score for mathematical communication skills reached 47.57, but in the second cycle, this average score increased to 72.75. Thus, there was an increase of approximately 36.68% in students' mathematical communication skills. Keywords: classroom action research; problem based learning; students’ mathematical communication skillAbstrakPenelitian tindakan kelas ini bertujuan untuk mengetahui apakah penerapan model pembelajaran Problem Based Learning (PBL) dapat meningkatkan kemampuan komunikasi matematis peserta didik pada materi bangun ruang sisi datar kelas VIII Zaid Bin Tsabit SMP IT Izzuddin Palembang semester genap tahun pelajaran 2023/2024. Penelitian ini dilaksanakan dalam dua siklus mencakup empat tahap yakni perencana, tindakan, pengamatan, dan refleksi. Subjek penelitian ini adalah peserta didik kelas VIII Zaid Bin Tsabit yang berjumlah 20 orang. Data penelitian diperoleh melalui tes kemampuan komunikasi matematis. Berdasarkan penelitian dan analisis yang dilakukan, didapati bahwa penerapan model Problem Based Learning (PBL) memiliki dampak positif terhadap peningkatan kemampuan komunikasi matematis para siswa kelas VIII Zaid bin Tsabit SMP IT Izzuddin Palembang pada semester genap tahun ajaran 2023/2024. Ini terbukti dari peningkatan yang signifikan pada kemampuan komunikasi matematis antara Siklus I dan Siklus II. Pada Siklus pertama, rata-rata nilai kemampuan komunikasi matematis mencapai 47,57, namun pada Siklus kedua, rata-rata nilai tersebut naik menjadi 72,75. Dengan demikian, terjadi peningkatan sekitar 36,68% dalam kemampuan komunikasi matematis siswa. Kata Kunci: kemampuan komunikasi matematis; penelitian tindakan kelas; problem based learningDOI: http://dx.doi.org/10.23960/mtk/v12i2.pp123-137
