The purpose of this study was to determine the trajectory of student learning on ball volume using quaci in Class IX. The research method, using a Validation Study design involving 38 students of class IX SMP Pagaralam PGRI. The stages of design research in learning consist of three phases: preparation for the experiment, design experiment, and retrospective analysis. Learning is carried out through three activities consisting of observing sunflowers, taking sunflower seeds, and wrapping them in accordance with PMRI's approach to ball volume material. The results showed that students could understand the concept of ball volume by completing a series of these activities. In addition, students have their own strategies in solving problems in each activity to express it in abstract form. Conclusion, the use of quaci in learning volumes of ball gives positive results for students in understanding problems related to real life in accordance with the PMRI approach.

The formulation of the problem in this study is whether there is the influence of the use of props the opportunity to turn on the material opportunities for learning outcomes of students in class VIII SMP Negeri 8 Pagaralam..?. the porpuse of this research is to find the influence of the matter opportunities in matter opportunities of the result of student learning. The method research used is the experimentel method with Pretes-postest control group desain. sampel in class experiment VIII.C class of the students the 30 and 70,56 while the sampel in class VIII.E control of the cclassroom and the number of students 30 and include 64,83. The teachnique of the collection of the data used as documentation and tests. T test data using analysis technique to that class of his experiments wit value s namely 12,06 while to that class of control with new value s namely 12,31 in a cantcount 1,88 > ttable 1,69, then H0 rejected dan Ha the study received reseived that hypothesis. So in conclusion any impact the use of props opportunities round on the subject matter of the results off student learning.
Berdasarkan kurikulum 2013 materi SPLDV merupakan satu dari beberapa materi di kelas VIII yang patut siswa kuasai. Dalam pelajaran SPLDV siswa diminta untuk mampu menggunakan kemampuan berpikir kritis untuk dapat identifikasi dan analisis masalah, membuat model matematika, menghubungkan masalah dengan konsep penyelesaian masalah, meminimalisir kesalahan sehingga menyelesaiakan persoalan dengan kesimpulan yang tepat. Tujuan penelitian ialah mencari tahu pengaruh model pembelajaran probing prompting menggunakan papan mamiku materi SPLDV kelas VIII terhadap kemampuan berpikir kritis matematis siswa SMP Muhammadiyah Pagaralam. Metode penelitian eksperimen ialah metode yang dipakai dengan kategori posttest only control design. Teknik pengumpulan data memakai tes dan observasi. Instrumen tes berupa soal essay divalidasi dan di uji reliabilitas sebelum penelitian dilaksanakan di kelas eksperimen dan kontrol. Teknik analisis data menggunakan uji normalitas, homogenitas dan uji hipotesis berbantuan SPSS. sampel penelitian ialah kelas VIII11 (kelas eksperimen) berjumlah 31 siswa dan nilai rata-ratanya 80,65 juga kelas VIII8 (kelas kontrol) berjumlah 31 siswa dengan nilai rata-rata 62, 65. Berasaskan hasil penelitian yang telah dilaksanakan didapat hasil nilai signifikan (2-tailled) yakni 0,000 berrati kurang dari 0,05, dengan nilai thitung yakni 5,645 lebih dari nilai ttabel yakni 1,7 sehingga H0 ditolak, maka kesimpulan penelitiannya ada pengaruh model pembelajaran probing prompting menggunakan papan mamiku pada materi SPLDV terhadap kemampuan berpikir kritis matematis siswa kelas VIII SMP Muhammadiyah Pagaralam tahun 2021/2022.
Observasi ini bertujuan untuk mengetahui keefektifan model problem based learning menggunakan alat peraga pantik terhadap hasil belajar siswa pada materi statistika kelas 8 SMP Muhammadiyah Pagar Alam Tahun Pelajaran 2021/2022. Bentuk desain observasi ini yaitu pretest posttest control group design . Populasi dalam observasi ini adalah semua siswa SMP Muhammadiyah Pagar Alam. Sedangkan sampel yang dikutip adalah 32 siswa kelas 8.6 (eksperimen) dan 32 siswa kelas 8.5 (kontrol). Metode akumulasi data berupa pengambilan gambar dan uji.Untuk memperkirakan hasil observasi diperoleh bahwasanya perhitungan rata-rata siswa yang memakai model pbl mendominasi perhitungan KKM sekolah yaitu 77 > 65. Maka dari itu, dapat memutuskan bahwasanya “model problem based learning menggunakan alat peraga pantik efektif hasil belajar siswa pada materi statistika kelas 8 SMP Muhammadiyah Pagar Alam Tahun Pelajaran 2021/2022”.

The purpose of this study was to determine the effectiveness of the PMRI approach with the context of cone rice on cone volume material on student learning outcomes in class IX of SMP Negeri 1 Pagaralam 2018/2019 academic year. The method used in this study was True-Experimental Design with a pre-test design posttest control group design. Sample of students including 30 students in the experimental class (IXH) and 32 control class students (IXI). The data collection techniques used were test and documentation. To measure student mathematics learning outcomes in this study used a written test in the form of essays totaling five questions. The hypothesis of the research is PMRI's approach to the context of cone rice in cone volume material is effective on student learning outcomes in class IX of SMP Negeri 1 Pagaralam 2018/2019 academic year. The results of students' mathematics test data using the PMRI approach with the context of cone rice on cone volume material on student learning outcomes in class IX of SMP Negeri 1 Pagaralam in the 2018/2019 academic year were obtained from the average.
