Abstract

This study aims to explain students pseudo-thinking errors on mathematical problem-solving skills  that are reviewed supported on high, medium, and low self-confidence. This research was conducted at SMAN 60 Jakarta class XI MIPA II for the 2020/2021 academic year. The subjects taken were 3 out of 38 students. This research method is a descriptive qualitative approach. Researchers used self-confidence questionnaires, problem-solving ability tests, and interviews. The material being tested is the derivative of algebraic functions. The results obtained stated that students with high self-confidence scored perfect test scores but there were a few writing errors. The completion step, therefore, included pseudo-correct thinking. Students with moderate self-confidence can do the questions well, but there are inaccuracies so that the results are wrong. Therefore, students with moderate self-confidence enter the indicator of pseudo-wrong thinking errors with information that can reflect on their answers. In students with low self-confidence, they face errors in compiling the completion steps but can rectify and find the correct answer. With this, students with low self-confidence fall into the indicator of pseudo-correct thinking errors with information on understanding the wrong concept.

Abstract

Literasi matematis merupakan literasi yang penting dimiliki oleh siswa. Namun pada kenyataannya masih banyak siswa yang belum menguasasi literasi ini dengan baik. Penelitian ini bertujuan untuk mengetahui Efektivitas Model pembelajaran blended learning berbasis learning management system terhadap kemampuan literasi matematis siswa Sekolah Dasar. Metode dalam penelitian ini yaitu metode kuantitatif eksperimen mengunakan desain penelitian yang Pre-test post-test control grup design. Sedangkan Populasi pada penelitian ini ialah siswa kelas IV SDN Cengkareng Barat 04 Petang yang terbagi menjadi dua sampel, diantaranya kelompok yang diberikan perlakuan (eksperimen) 30 siswa dan kelompok pembelajaran konvensional (control) 30 siswa. Adapun teknik analisis data yang digunakan yaitu uji prasyarat menggunakan uji normalitas dan homogenitas sedangkan uji hipotesis menggunakan Paired sample t-test dan effect size. Dari hasil perhitungan diketahui nilai rata-rata kelas eksperimen pada hasil post test sebesar 82,93 dan 75,80 pada hasil penilaian akhir kelompok Kontrol. Karena >  Maka ditolak dan dapat diterima. Oleh karena itu, ditemukan perbedaan yang signifikan antara kelas eksperimen (model blended learning berbasis google classroom) dan kelas control (Model Konvensional). Demikian dapat dikatakan bahwa model Blendeed Learning berbasis learning management system (google classroom) dapat meningkatkan kemampuan literasi matematis siswa Sekolah Dasar.

Abstract

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.
