Abstract

Rendahnya hasil belajar matematika siswa disebabkan oleh beberapa faktor yaitu materi pelajaran yang dirasakan masih bersifat abstrak dikarenakan kurangnya contoh yang diaplikasikan dalam kehidupan dunia mereka, dan juga metode pembelajaran yang digunakan oleh guru adalah metode ceramah dan tanya jawab sehingga siswa cenderung pasif dalam proses pembelajaran. Salah satu pendekatan yang erat kaitannya dengan kehidupan sehari-hari siswa adalah Pendekatan Pendidikan Matematika Realistik Indonesia. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan pendekatan Pendidikan matematika realistik Indonesia terhadap hasil belajar pada pokok bahasan teorema Pythagoras. Jenis penelitian yang digunakan adalah penelitian eksperimen yang menggunakan metode pre eksperimental dengan menggunakan desain one group pretest- posttest. Penelitian ini dilakukan pada kelas VIII SMP Negeri 1 Wewewa Tengah dengan subjek penelitian ini yakni siswa kelas VIII A. Data yang dikumpulkan berupa pretest dan posttest dalam bentuk uraian untuk menilai hasil belajar siswa. Teknik analisis data yang digunakan adalah analisis statistik, dengan bantuan program SPSS versi 29. Berdasarkan hasil penelitian menunjukkan bahwa pendekatan Pendidikan matematika realistik Indonesia memiliki pengaruh terhadap hasil belajar siswa.

Abstract

Penelitian ini dilakukan untuk mengetahui tentang proses dan unsur-unsur matematika yang terdapat pada pembuatan batu kubur dan pembangunan rumah adat di Kampung Wailolung Kabupaten Sumba Tengah. Penelitian ini dilakukan di Kampung Wailolung, Kabupaten Sumba Tengah, NTT. Jenis penelitian ini merupakan penelitian kualitatif deskriptif. Data yang dikumpulkan berupa hasil dokumentasi dan wawancara. Dari hasil wawancara diperoleh bahwa proses pembuatan batu kubur dan pembangunan rumah adat di Kampung Wailolung melibatkan tiga tahap utama yaitu perencanaan, persiapan dan pelaksanaan. Setiap tahapan mencakup berbagai aktivitas etnomatematika seperti menghitung, mengukur, merancang dan menjelaskan. Kami menemukan bahwa unsur-unsur matematika pada proses pembuatan batu kubur yaitu pengukuran dan geometri, konversi satuan, estimasi anggara dan statistika deskriptif serta ditemukan unsur-unsur matematika pada proses pembangunan rumah adat yaitu pengukuran dan penentuan ukuran, kalkulasi dan estimasi, waktu dan biaya, serta geometri dan struktur.

Abstract

The cause of the problem of low learning outcomes for fourth grade students at Pogo Lede State Elementary School in mathematics subjects consists of teacher and student foctors. Teachers are less creative in delivering material, do not use media that, can attract students’ attention and interest in learning, focus more on using prinred books, and do not involve students. Apart from that, he also has difficulty in calculating. This makes students feel bored, fed up and sometimes students just sit still during the learning process so that the material provided by the teacher cannot be received optimally, causing the learning outcomes of class IV students at SD Negeri Pogo Ledeto still be below average. This research uses classroom action research (PTK) techniques because the research is carried out to solve problems that occur in the claasroom. In classroom action research improvements are carried out gradually and continuously as long as the research activities are carried out. Therefore, in PTK there is an implementation cycle in the from of a planning pattern. Carrying out observations and reflections so that in the next dycle it reaches the level you want to achieve. Based on the background above, the researcher chose to apply the puzzle game learning method. This method can make students activel discuss in class or in small groups to formulate the title improving learning outcomes using puzzle game tools on operation material counting mixed integers class IV Pogo Lede State Elementary School

Abstract

The Academic Potential Test is a test that aims to measure a person's abilities in the general academic field. This test is also often associated with intelligence. Currently, apart from selecting prospective students at universities, The Academic Potential Test has also become a standard test in the selection of Civil Servant Candidates and in the recruitment of private employees and employees of State-Owned Enterprises. Based on the background above, it is necessary to measure the ability of students from the Mathematics Education Study Program at Catholic University Weetebula in solving test questions. This needs to be done as a first step in determining the abilities of prospective graduates. The method used in this research was by giving a written test in the form of test questions to 56 students and interviews with 9 students who took the test. The instruments used were 40 test questions and an interview guide. The data analysis techniques used are reduction, presentation and drawing conclusions. The test results show that students who get the low category are 84%, students who get the Average category are 7% and students who get the high category are 9%. The interview results showed that students were able to understand the test questions given, but students had difficulty determining how to solve them, so students were unable to determine the correct answer

Abstract

This research aims: to find mathematical aspects found on the roof of a loura traditional house, apply the mathematical aspects found in learning the roof of a loura traditional house. This research was conducted at SMKN 2 Tambolaka City class X. This type of research is research and development (Research and Development). Data are obtained from the results of filling out observation sheets and, tests and taking documentation. Loura traditional houses have mathematical aspects such as triangles. The results obtained from the implementation of the research showed an increase, this can be seen from the results of student answers on student worksheets and an increase in student activity in terms of questions and answers in class and their active and critical way of thinking. Likewise, the learning outcomes of each action showed improvement. Thus, it can be concluded that the use of learning media in trigonometry material on the roof of a loura traditional house at SMKN 2 Tambolaka City based on the results of research can improve mathematics learning outcomes and teachers can try to apply this method so that students are active and motivated in learning mathematics

Abstract

The purpose of this study is to determine students' mathematical communication skills after the application of the problem based learning model of number pattern material in grade VIII students of SMP Negeri 4 Loura. The type of research is a descriptive qualitative method. Data collection uses interviews and documentation. The data analysis process is carried out qualitatively consisting of data reduction, data presentation, and conclusion drawn. The results of the study showed that from each level of the percentage level of the student communication ability category, namely the percentage level of the high category was 20%, medium 20% and low 60%. The impact of this ability is that students do not relearn the material that has been given during learning and do not pay attention to the researcher delivering the material
