In mathematics learning, concepts and contexts are required that students are able to learn from real-life environment. However, teachers generally equip students with formulas without being accompanied by the ability to comprehend basic concepts. Mathematics learning will indeed be enjoyable if it is not only textbook-based but also followed by real-life experience. This study aims to investigate whether local cultural context could foster students' concept understanding in mathematics learning, particularly plane figures. Therefore, the research will, firstly, describe plane figures learning that uses the Indonesian Realistic Mathematics Education approach via iceberg and, secondly, discover students' improvement in concept comprehension after applying the approach. 50 elementary school students participated in the research, which employed experimental and descriptive methods. Further, the study results demonstrate an increase in concept comprehension, indicated from the increase in student learning achievement based on the average score of the experimental class and of the control class (88.40 and 72.91 respectively). Next, the independent sample ttest suggests t-count is higher than t-table, therefore Ho is rejected and Ha accepted. Thus, the learning outcomes of the class using the PMRI approach linked to Palembang's cultural context has increased.

AbstrakKemampuan pemecahan masalah matematis menjadi salah satu komponen yang perlu dianalisis untuk mengetahui kemampuan peserta didik terhadap satu topik pembelajaran. Penelitian ini bertujuan untuk menganalisis kemampuan pemecahan masalah matematis peserta didik pada materi bangun datar, pengukuran panjang dan berat. Metode penelitian yang digunakan adalah kualitatif deskriptif. Instrumen pengumpulan data melalui tes, kuesioner, dan dokumentasi. Keseluruhan data tersebut dianalisis dan dideskrispsikan oleh peneliti. Subjek dalam penelitian ini adalah peserta didik kelas IV di salah satu sekolah swasta di Palembang berjumlah 14 orang yang diperoleh melalui purposive sampling. Hasil dari penelitian ini adalah kemampuan pemecahan masalah pada materi bangun datar dan pengukuran pada peserta didik kelas IV di salah satu sekolah swasta tersebut sebesar 75,59% yang artinya berkategori baik. Kemampuan pemecahan masalah peserta didik kelas IV perlu ditingkatkan terutama pada sesuatu yang sifatnya konkret dengan membiasakan peserta didik memberikan soal-soal berkonteks cerita yang mengarah ke AKM, PISA, dan HOTS kedepannya. AbstractMathematical problem-solving ability is one of the necessary components to analyze as it demonstrates students' ability to comprehend a learning topic. This study aimed to analyze students' mathematical problem-solving skills on flat shapes, measuring length and weight. This descriptive qualitative study used tests, questionnaires, and document analysis to collect the data. All of the data were analyzed and described by the researcher. The participants of the study were 14 fourth grade students in a private school in Palembang selected through purposive sampling technique. The study revealed that the students’ problem-solving abilities on flat shapes and measurements scored 75.59%, which was categorized as “good”. The problem-solving abilities of fourth graders need to be improved, especially on concrete objects by inuring students to story-context questions that promote AKM, PISA, and HOTS in the future.

The unsatisfactory results of the Programme for International Student Assessment (PISA) in Indonesia related to reading become the urge for analysing students' reading comprehension. The objective of this research was to analyse the reading comprehension of Grade IV students at one of the private primary schools in Palembang by using a parenting context. The parenting context was implemented in the form of colouring picture stories. Further, this research employed descriptive qualitative method. Data collection techniques used were tests, questionnaires, and documentation. As regards sampling technique, a purposive sampling was applied, based on the class criteria of Grade IV students who enrolled the offline class. It should be noted that this study was conducted after the peak of pandemic crisis but most schools still enrolled online class. Finally, the results of this study demonstrate that students perceive they are most likely to learn and be motivated in learning English through colouring parenting-related pictures.
