Abstract

Understanding mathematical concepts is one of the competencies in learning mathematics, but not all students possess this competency yet. To address this problem, the author implemented realistic mathematical education (RME) in mathematics learning to optimize students’ understanding of mathematical concepts. The purpose of the RME implementation was to optimize students’ mathematical concepts understanding. The research method used was a descriptive qualitative method, namely by examining an object in its natural condition. The implementation of RME in mathematics learning uses real-life problems by actively conditioning students to construct their understanding of mathematical concepts, while teachers play an active role as facilitators. The results showed that the implementation of RME in mathematics learning can optimize students’ understanding of mathematical concepts. Thus, it can be concluded that the implementation of RME in mathematics learning can optimize students' understanding of mathematical concepts.BAHASA INDONESIA ABSTRACT: Pemahaman konsep matematika merupakan salah satu kompetensi dalam pembelajaran matematika, tetapi kompetensi tersebut belum dimiliki oleh semua siswa.

Abstract

The results of the PISA study in 2018 showed that the mathematics ability of Indonesian students was still in the low performance category. One of the factors that causes this is the lack of student interest in learning mathematics. Interest is very important because it is interest that encourages students to be active and act in learning. This study aims to see whether the application of a smartphone-based discovery learning model can help increase interest in learning mathematics. The research method used is a descriptive qualitative research method using several research instruments. This research was conducted in one of the schools in South Tangerang at the junior high school level. The instruments used by the authors are observation sheets and reflection sheets and mentor feedback sheets. The results of this study concluded that the application of a smartphone-based discovery learning model is able to effect student interest in learning, which is shown by an increased willingness to learn, pleasure in learning, and student participation.BAHASA INDONESIA ABSTRACT: Hasil studi PISA pada 2018 menunjukkan kemampuan matematika siswa Indonesia masih berada dalam kategori low performance.

Abstract

Global and country-specific mathematics performance constitutes a major challenge, both for educators and policymakers. Realisation of the African Union Agenda 2013 hinges significantly upon transformation of education. In this regard, mathematics and science education, specifically, are instruments for scientific and technological development to position Africa on the same level as the global league of continents in the future. It is, therefore, important to develop amongst learners a good understanding of a mathematical concept such as number sense from an early age, given that students who have a good sense of numbers can manipulate figures to simplify calculations and have the confidence to approach problems in a variety of ways. It is for this reason that the present study investigates the intervention strategies implemented by educators in enhancing learners’ understanding of number sense in the Ekurhuleni North District schools, Gauteng Province, South Africa. The study used a case study design and a qualitative research approach, both of which were supported by an interpretivist paradigm. The study made use of a semi-structured interview to gather data from mathematics teachers, learners, and a principal in the selected school. Research findings revealed that although mental computation, use of concrete props, use of the number line, and a counting strategy are some of the various strategies employed to enhance learners’ understanding of number sense, teachers need to develop a sound understanding of number sense and be flexible in their approaches in order to assist learners. Based on the findings, it was recommended that curriculum designers and teachers concentrate on teaching methods to help students develop learners’ number sense, as this can lead to potential mathematics success.

Abstract

Because students were having trouble picturing the three-dimensional system of coordinates in a spatial analysis geometry course, their mathematical problem-solving abilities were still low. Educational movies that aid in visualization are essential for pupils. The study at hand used a design consisting of a pretest-posttest control group and was quasi-experimental in nature. While the control class experienced conventional teaching, the learners in the experimental group learned using three-dimensional coordinate system audiovisual media. A test of one's capacity to solve mathematical problems was used, along with observation sheets and interviews. A total of thirty-four participants made up the sample for this study, which was carried out at the University of Pattimura's Mathematics Education Study Program. Evaluation was of t-testing outcomes on mathematical problem-solving skills. The findings demonstrated that students' proficiency in solving problems with mathematics increased when they were taught to use a video about the three-dimensional coordinate system.

Abstract

The low level of mathematical disposition ability of the students in one of the Junior High Schools in Palembang became a special matter during the field experience. It was found that the average percentage of students' mathematical disposition ability was 53.01% in the moderate category. In addition, there were students who had a view of mathematics as a difficult and unpleasant science. In fact, mathematical disposition has a great influence on students' mathematics learning and achievement. Moreover, it will help students to see the beauty of God's creation through mathematics if they have a good mathematical disposition. This makes the Indonesian Realistic Mathematics Approach (PMRI) an alternative solution to the problem of mathematical disposition. The purpose of writing this thesis was to find out whether the application of PMRI could develop the disposition ability of algebra material and to describe the application of PMRI in developing the mathematical disposition ability of students in algebra material using a descriptive qualitative method. The results and conclusions of this paper show that the students' mathematical disposition ability after the application of PMRI increased with an average percentage result to 61.48% in the good category. The increase was caused by the mathematical disposition indicators that were refined in all PMRI syntax. Thus, these indicators can be refined in any syntax. Reflecting on the application of PMRI, it is suggested that the application can be done more than twice and use physical learning media.BAHASA INDONESIA ABSTRACT: Rendahnya kemampuan disposisi matematis siswa di salah satu SMP di Palembang menjadi perhatian khusus saat dilakukannya praktik pengalaman lapangan. Didapatkan rata-rata persentase kemampuan disposisi matematis siswa berada pada 53,01% dengan kategori cukup. Ditambah lagi terdapat siswa yang memiliki pandangan terhadap matematika sebagai suatu ilmu yang sulit dan tidak menyenangkan. Padahal, disposisi matematis sangat berpengaruh terhadap pembelajaran matematika dan prestasi siswa. Apalagi, dengan baiknya disposisi matematis siswa, maka akan mendukung mereka memandang indahnya ciptaan Tuhan melalui matematika. Hal ini menjadikan Pendekatan Matematika Realistik Indonesia (PMRI) menjadi alternatif solusi terhadap permasalahan disposisi matematis. Tujuan dari penelitian adalah untuk mengetahui apakah penerapan PMRI dapat mengembangkan kemampuan disposisi materi aljabar dan mendeskripsikan penerapan PMRI dalam mengembangkan kemampuan disposisi matematis siswa pada materi aljabar dengan menggunakan metode kualitatif deskriptif. Hasil dan simpulan penulisan ini menunjukkan bahwa kemampuan disposisi matematis siswa setelah PMRI diterapkan mengalami peningkatan dengan rata-rata hasil persentase menjadi 61,48% dengan kategori baik. Hasil persentase yang meningkat ini disebabkan oleh indikator disposisi matematis yang terdapat pada keseluruhan sintaks PMRI. Dengan demikian, indikator-indikator tersebut dapat terasah di setiap sintaks. Berkaca dari penerapan PMRI ini, disarankan agar penerapannya dapat dilakukan lebih dari dua kali dan menggunakan media pembelajaran fisik.

Abstract

One of the problems with learning mathematics is students' difficulty in understanding the material. This difficulty is often accompanied by a sense of boredom, especially at the junior high school level. One solution to address this issue is the use of self-designed and organized digital mathematics comics to help students overcome difficulties and capture their attention. This research aims to implement valid and practical digital mathematics comics in the learning of number sequence pattern. This qualitative descriptive research was conducted by collecting data through questionnaires, observation sheets, and unstructured interviews. In the implementation of learning number sequence patterns using digital mathematics comics, 88 percent were found to be valid, and 89 percent were proven to be very practical based on the responses of 9 eighth-grade students from one of the private junior high schools in Malang who used it. Students were able to read, interact actively, and complete each exercise available in the media. Teaching mathematics using digital mathematics comics is recommended for implementation in other schools.BAHASA INDONESIA ABSTRACT: Salah satu masalah yang terjadi pada pembelajaran matematika adalah kesulitan siswa dalam memahami materi.
