“…Furthermore, it is stated that in fact, the results of the tests showed that most students lacked comprehending of the basic skills that they should have studied in primary school and in daily life problems. The meaningful context can promote students' learning from informal level to preformal level consisting mathematical ideas (Pramudiani et al, 2011).…”

This study aims to investigate primary school students’ mathematical thinking in column calculation and algorithms. The method used in this research is qualitative descriptive. The participants of this research were twelve Indonesian primary school students at grade 3 and 4 in Ciparay, Bandung, West Java. They worked to solve calculation and algorithm questions developed from TAL TEAM book Freudenthal Institute, Utrecht University, The Netherlands that were classified based on the strategies used. After analyzing their written works, interviews were organized to acquire further information about their mathematical thinking. The study found that students’ strategies in dealing with calculation algorithm consist of three strategies. The first strategy is the splitting strategy from units to tens column and then the interim results are combined. The second strategy is the splitting strategy used from tens to unit column and the interim results are added vertically digit-by-digit. The third strategy is the transition from splitting strategy from units to tens column consists primarily of using abbreviated column calculation for the interim results in each column. In addition, several students made common mistakes due to misconception about algorithm and arithmetical problems. Implication of this research for teaching and learning calculation and algorithms were described elaborately.

“…Kegiatan ini sejalan dengan pendapat Freudenthal bahwa pembelajaran matematika yang dipelajari karena matematika merupakan aktivitas manusia dan bukanlah suatu ilmu yang dipindah dari guru ke siswa. Hal ini sejalan dengan pendapat Caruth (2019) bahwa proses aktif yang memungkinkan siswa dalam memahami pembelajaran sesuai pengetahuan yang dimiliki sehingga pembelajaran menjadi bermakna bagi siswa (Pramudiani, 2011) dapat memengaruhi kemandirian belajar siswa.…”

“…Proses aktif akan memungkinkan siswa dalam melaksanakan pembelajaran disesuaikan dengan pengetahuan yang dimilikinya sehingga siswa dapat mandiri dalam belajarnya (Caruth, 2019). Kontekstual yang dimaksud yaitu dengan menghubungkan permasalahan di kehidupan sehari-hari siswa dengan materi yang akan dipelajari sehingga pembelajaran menjadi suatu pembelajaran yang bermakna bagi siswa (Pramudiani et al, 2011). Selain itu, kemandirian dapat didefinisikan sebagai suatu tindakan yang tidak bergantung dengan orang lain dalam menyelesaikan permasalahan terkait tugas belajarnya (Kemendiknas, 2010).…”

Abstract: This study aims to describe the Realistics Mathematics Education (RME) approach in increasing the independence of students' mathematics learning in the material area and around square and rectangle. This type of research was classroom action research. The subject of this study were fourth grade students of Elementary School consisting of 29 students. Learning devices in this study were Learning Implementation Plans and Group Worksheets while the instruments used in this study are observation sheets of student learning independence, teacher observation sheets, questionnaires, and interview guidelines. The results of the study showed that the RME approach that was packaged by giving problems in the form of written or unwritten stories that enabled students to find different solutions/answers and using manipulative media could improve student learning independence with the average student categorized well.Abstrak: Penelitian ini bertujuan untuk mendeskripsikan pendekatan Realistics Mathematics Education dalam meningkatkan kemandirian belajar matematika siswa pada materi luas dan keliling persegi dan persegi panjang. Jenis penelitian ini merupakan penelitian tindakan kelas. Subjek penelitian ini yaitu siswa kelas IV yang terdiri dari 29 siswa. Perangkat pembelajaran pada penelitian ini yaitu Rencana Pelaksanaan Pembelajaran dan Lembar Kerja Kelompok, sedangkan instrumen yang digunakan dalam penelitian ini yaitu lembar observasi kemandirian belajar siswa, lembar observasi guru, angket, dan pedoman wawancara. Hasil penelitian menunjukkan bahwa pendekatan RME yang dikemas dengan pemberian permasalahan berupa cerita secara tertulis maupun tidak tertulis yang memungkinkan siswa menemukan berbagai solusi/jawaban yang berbeda-beda dan menggunakan media manipulatif dapat meningkatkan kemandirian belajar siswa dengan rata-rata siswa berkategori baik.

“…Indonesian textbooks commonly consist of the tasks full of mathematics role and algorithms (Zulkardi, 2002;Pramudiani, Zulkardi, Hartono, van Amerom, 2011). In solving the beads problem, the pupils try to find the best strategy to find the amount.…”

The intention of the present study is to know how the pupils can learn to make a group of ten to understand the idea of unitizing. The pupils were given a contextual problem "Counting the Beads" in order to promote their understanding about the idea of unitizing. The process of designing the problem was based on the 5 tenets of Indonesian Realistic Mathematics Education (IRME). The methods of this study was a design research. The researcher designed the Hypothetical Learning Trajectory (HLT) before conducting the lesson in the classroom. The result of this study showed that the pupils learned to make a group of any number then moved to make a group of twenty before using the group of ten as a strategy in finding the amount of the beads. The pupils set a structure of objects with a help of grouping to ten strategy to understand the idea of unitizing.
