Pada saat belajar matematika sering mengalami kendala yang disebabkan ketika pembelajaran tidak memberikan contoh konkret dari objek matematika yang abstrak. Tujuan penelitian ini adalah untuk menganalisis etnomatematika yang terdapat di kue lebaran. Metode yang digunakan penelitian kualitatif dengan pendekatan etnografi. Total objek yang diteliti ada 4 buah kue lebaran, yaitu kue lidah kucing, kue kastangel, kue putri salju, kue nastar, dan 1 subjek untuk diwawancara, yaitu pedagang kue. Teknik penelitian ini menggunakan observasi, wawancara, dan dokumentasi. Hasil penelitian ini diperoleh Diantaranya pada kue nastar yang terbentuk dari bangun ruang setengah bola, kue putri salju yang terbentuk dari juring dan tembereng lingkaran kue kastangel yang terbentuk dari bangun ruang balok, dan kue Lidah kucing yang terbentuk dari bangun datar persegi panjang dan setengah lingkaran. Diharapkan dari pembelajaran konstektual yang menggunakan kue lebaran sebagai media pembelajaran dapat membantu serta menambah wawasan dalam memahami konsep bangun geometri pada matematika.At the time of learning mathematics often experience obstacles caused when learning does not provide concrete examples of abstract mathematical objects. The purpose of this study was to analyze the ethnomathematics contained in the Eid cake. The method used is qualitative research with an ethnographic approach. The total objects studied were 4 Eid cakes, namely cat tongue cake, kastangel cake, snow-white cake, nastar cake, and 1 subject to be interviewed, namely a cake seller. This research technique uses observation, interviews, and documentation. The results of this study were obtained. Among them are nastar cakes which are formed from a half-spherical shape, snow princess cakes which are formed from circles and circles of kastangel cakes which are formed from blocks of space, and cat's tongue cakes which are formed from rectangular and semi-circular flat shapes. It is hoped that contextual learning using Eid cakes as a learning medium can help and add insight into understanding the concept of geometric shapes in mathematics.
<p>Penelitian ini bertujuan guna mengetahui pengaruh kecemasan matematika terhadap kemampuan penalaran matematis pada siswa kelas VIII saat pembelajaran daring dan juga mengetahui profil kecemasan matematika siswa dan kemampuan penalaran matematis. Metode kuantitatif dengan penelitian korelasional digunakan dalam penelitian ini. Peneliti mengambil sampel 450 siswa kelas VIII di SMPN DKI Jakarta. Dalam mengolah data menggunakan teknik analisis deskriptif serta regresi linear sederhana. Hasil dari penelitian ini memaparkan kecemasan matematika berada di kategori sedang dengan 67.3% dan kemampuan penalaran matematis berkategori sedang sebanyak 65.1%. Serta tidak terdapat pengaruh kecemasan matematika terhadap kemampuan penalaran matematis pada siswa kelas VIII saat pembelajaran daring</p><p><em>This study aims to determine the profile and influence of mathematics anxiety on mathematical reasoning abilities in class VIII students during online learning. Quantitative methods with correlational research are used in this study. Researchers took a sample of 450 class VIII students at SMPN DKI Jakarta. In processing the data using descriptive analysis techniques and simple linear regression. The results of this study show that mathematics anxiety is in the moderate category at 67.3% and the mathematical reasoning ability in the medium category is 65.1%. And there is no influence of math anxiety on mathematical reasoning abilities in class VIII students when learning online</em></p>
Learning outcomes are an assessment of the abilities possessed by students after participating in the learning process. Low learning outcomes caused by low scientific argumentation. This study aims to determine the relationship between learning outcomes and the ability of scientific argumentation of students of SMAN 1 Payakumbuh on the immune system material. This research is a descriptive study with the correlation method. The research sample consisted of 34 students of class XII MIPA 8 SMAN 1 Payakumbuh. . The research instrument is in the form of valid student learning outcomes tests and scientific argumentation ability tests. The results showed that students' learning outcomes were in the moderate category with an average of 63% and students' scientific argumentation abilities were included in the weak category with an average of 39.02%. There is a positive and significant correlation between learning outcomes and the scientific argumentation abilities of class XII MIPA 8 students in the immune system material with a value of r = 0,658 which is in the very strong category. The value coefficient = 6,562 is greater than the coefficient =2,0369. So it can be concluded that there is a positive and significant relationship between learning outcomes and scientific argumentation abilities of SMAN 1 Payakumbuh students on the immune system material.
