Abstract

In Mathematics there are many branches of mathematics, one of which is Calculus. Calculus is often considered a difficult branch of mathematics. However, even so, Calculus is very useful in everyday life, even though we rarely realize this. Calculus greatly contributed to the development of mathematics. Not only mathematics, Calculus also contributes to the field of Physics. Looking at it from a historical perspective, Calculus has a controversial history because there are disputes between its inventors, namely Newton and Leibniz. Apart from the disputing figures, many other figures took part in this branch of Calculus. This calculus originated from the idea of calculating area by the Greek scientist Archimedes, although at that time Archimedes had not given the name calculus but he was the first to introduce the concept of calculus. From century to century, year after year the science of calculus always changes, because figures discover something new. Currently, although there are no new discoveries, the use of Calculus continues to grow from being only studied in universities to high schools. Apart from this, the use of calculus used to be simple, but now it has become more complex.

Abstract

Tujuan dari penelitian ini adalah untuk mendeskripsikan tingkatan kemampuan numerasi siswa yang menggunakan pendekatan PMRI dalam pembelajarannya. Penelitian ini dilakukan selain karena adanya masalah mendasar dalam literasi matematika siswa dan masih sedikitnya penelitian mengenai pendekatan pembelajaran yang efektif untuk mengembangkan numerasi siswa, keterampilan ini adalah bekal siswa dalam kehidupan untuk dapat menggunakan matematika dalam berbagai konteks kehidupan nyata untuk pengambilan keputusan dan pemecahan masalah. Penelitian ini adalah penelitian deskriptif kualitatif dengan subjek penelitian adalah 18 orang siswa kelas X SMK Muhammadiyah di Yogyakarta. Data yang dikumpulkan dalam penelitian ini berupa hasil observasi, hasil wawancara, catatan lapangan, dan dokumen hasil pekerjaan siswa. Teknik analisis yang digunakan dalam penelitian ini adalah reduksi data, penyajian data, dan penarikan kesimpulan dan verifikasi. Hasil penelitian menunjukkan bahwa kemampuan numerasi siswa berada pada level perlu intervensi khusus, dasar, dan cakap. Beberapa faktor yang menjadi penghambat dalam pelaksanaan penelitian di antaranya siswa belum terbiasa dengan pendekatan PMRI dalam kegiatan pembelajaran dan minimnya pengalaman siswa dalam menyelesaikan soal-soal numerasi atau masalah matematika yang memiliki konteks atau situasi yang berkaitan dengan kehidupan. The aim of this present study is to describe students’ level of numeracy competence using PMRI approach in learning mathematics. This research is conducted not only because og the fundamental issues in students’ mathematical literacy and the lack of studies on effective learning approaches to develop students’ numeracy, but also because these skills are essential for students in life to use mathematics in various real-life contexts for decision-making and problem-solving. This study is a qualitative descriptive which involved 18 Vocational School students grade X in Yogyakarta. Data collection in this research consisted of observation result, interview results, field notes, and students’ works. The analysis techniques used in this research are data reduction, data presentation, and drawing inferences and verification. The study showed that students’ level of numeracy competence was in the level of need for specific intervention, elementary, and capable. Several factors that inhibited the impelementation of research included students not being accustomed to the PMRI approach in learning and students’ lack of experiences in solving numeracy problems or mathematical problems that have a context or situation related to daily life.
