This research is motivated by the ability to solve mathematical problems in elementary schools is still not optimal in fact learning mathematics in Indonesia still does not provide satisfactory results. This study aims to describe the open-ended approach to the problem-solving abilities of elementary school students. The research method used in this study is the Systematic Literature Review (SLR) by identifying, assessing, and interpreting all the findings in a study to answer research questions that have been determined previously. This study examines 13 articles on the final results of screening based on inclusion criteria, there are 4 journals using the Classroom Action Research method, 4 journals using quasi-experimental research methods, 2 journals using experimental research methods, 2 journals using quasi-experimental research methods, and 1 journal using quasi-experimental research methods. qualitative research. Based on the analysis of 13 study materials, the results on the application of the open-ended approach to elementary school students increased in each cycle. It can be seen the difference between the results of the application of the open ended approach in the high and low classes, namely in the first cycle of 23%, the second cycle of 5%, and the third cycle of 1.1%. Based on these results, it can be concluded that the application of an openended approach can improve the mathematical problem solving ability of elementary school students.
Matematika merupakan pembelajaran yang penting dan harus dikuasai oleh setiap individu, karena pembelajaran matematika sangat bermanfaat bagi kehidupan sehari- hari. Penelitian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah matematika siswa di sekolah dasar. Jenis penelitian ini menggunakan pendekatan kualitatif dan analisis data dengan mengumpulkan beberapa jurnal ilmiah sebagai pedomannya, dimana menekankan pada penyimpulan data berdasarkan perbandingan pustaka dalam jurnal ilmiah. Hasil penelitian menunjukan bahwa dengan menggunakan pendekatan Realistic Mathematics Education dapat meningkatkan kemampuan pemecahan masalah matematika siswa, dengan menggunakan pendekatan tersebut dapat melibatkan siswa secara aktif dalam pembelajaran, membantu mengembangkan kreatifivitas siswa dan juga rasa kepercayaan diri siswa dalam belajar, membantu siswa menemukan kembali suatu konsep pembelajaran melalui pengalaman sehari-hari, dan pembelajaran pun menjadi lebih bermakna karena siswa bisa membangun pengetahuannya sendiri untuk menemukan konsep dari materi yang dipelajari. Dengan demikian dapat disimpulkan bahwa dengan menerapkan pendekatan Realistic Mathematics Education dapat dijadikan sebagai solusi untuk meningkatkan kemampuan pemecahan masalah matematika di sekolah dasar.
This research is motivated by the low problem solving ability of students in Mathematics in class V SDIT Nurut Taqwa West Cikarang. This study aims to improve the ability to solve Mathematical problems through Problem Posing learning models for fifth grade students at SDIT Nurut Taqwa Cikarang Barat. This research method uses Classroom Action Research (CAR) which consists of 3 cycles. Each cycle consists of stages of action planning, implementation of actions, stages of observation and assessment, then reflection. Subjects numbered 19 students. The data in this collection was obtained using data collection techniques in the form of written tests and observations. The criterion for success in this study is if 80% of the number of students reach the KKM value that has been set is 70. Based on the results of the study obtained in cycle I, the problem solving ability of students obtained a percentage of mastery learning by 32% with an average value of 58.95. In cycle II, the problem solving ability of students obtained a percentage of completeness of 63% with an average value of 74. In cycle III, the problem solving ability of students obtained a percentage of mastery learning by 89% with an average value of 85. The conclusion of this study is a model Problem Posing learning can improve Mathematical problem solving skills in fifth grade students at SDIT Nurut Taqwa Cikarang Barat. AbstrakPenelitian ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah siswa dalam mata pelajaran Matematika di kelas V SDIT Nurut Taqwa Cikarang Barat. Penelitian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah Matematika melalui model pembelajaran Problem Posing pada siswa kelas V di SDIT Nurut Taqwa Cikarang Barat. Metode penelitian ini menggunakan Penelitian Tindakan Kelas (PTK) yang terdiri dari 3 siklus. Setiap siklus terdiri dari tahapan perencanaan tindakan, pelaksanaan tindakan, tahapan pengamatan dan penilaian, kemudian refleksi. Subjek berjumlah 19 siswa. Data dalam pengumpulan ini diperoleh dengan menggunakan teknik pengumpulan data berupa tes tertulis dan observasi. Kriteria keberhasilan dalam penelitian ini adalah apabila 80% dari jumlah siswa mencapai nilai KKM yang telah ditetapkan yaitu 70. Berdasarkan hasil penelitian diperoleh pada siklus I, kemampuan pemecahan masalah siswa memperoleh presentase ketuntasan belajar sebesar 32% dengan nilai rata-rata sebesar 58,95. Pada siklus II, kemampuan pemecahan masalah siswa memperoleh presentase ketuntasan 63% dengan nilai rata-rata sebesar 74. Pada siklus III, kemampuan pemecahan masalah siswa memperoleh presentase ketuntasan belajar sebesar 89% dengan nilai rata-rata sebesar 85. Kesimpulan dari penelitian ini adalah model pembelajaran Problem Posing dapat meningkatkan kemampuan pemecahan masalah Matematika pada siswa kelas V di SDIT Nurut Taqwa Cikarang Barat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
