Philosophy of mathematics does not add a number of new mathematical theorems or theories, so a philosophy of mathematics is not mathematics. The philosophy of mathematics is an area of ​​reflection about mathematics. After studying for a long time, one needs to reflect on learning outcomes by reflecting on the philosophy of mathematics. Mathematics and philosophy are closely related, compared to other sciences. The reason is that philosophy is the base for studying science and mathematics is the mother of all sciences. There are also those who think that philosophy and mathematics are the mother of all existing knowledge. From a historical perspective, the relationship between philosophy and mathematics underwent a very striking development. This article discusses the development of mathematics in philosophy and the flow of formalism contained in the philosophy of mathematics in particular

Penelitian ini dilaksanakan di SMA Negeri 1 Kutalimbaru Tahun Ajaran 2020/2021 untuk mengetahui perbedaan kemampuan berpikir kritis matematis siswa antara model pembelajaran problem posing dan discovery learning. Pengumpulan data penelitian menggunakan teknik observasi untuk melihat pencapaian proses pembelajaran sudah sesuaI atau tidak dengan model pembelajaran dan tes untuk melihat perbedaan kemampuan berpikir kritis matematis serta siswa antara model pembelajaran problem posing dan discovery learning. Hasil penelitian menunjukkan bahwa: 1)  pencapaian proses pembelajara problem posing adalah sebesar 4,8 dengan kategori “Sangat Baik” pencapaian proses pembelajaran discovery learning adalah sebesar 4,867 dengan kategori “Sangat Baik”. 2) Tidak terdapat perbedaan kemampuan berpikir kritis matematis antara siswa yang memperoleh model problem posing dengan discovery learning. Hal ini terlihat dari hasil uji statistika, dimana nilai probabilitas (sig.) untuk kedua pembelajaran  lebih besar dari taraf signifikansi  = 0,05 yang ditetapkan, sehingga H0 diterima. Namun secara matematis nilai rata-rata kemampuan berpikir kritis matematis siswa berbeda

The control device in an auto-navigation car is a computer assisted by two cameras on the front of the car to determine the three-dimensional coordinates of all pixels of the digital image captured by the camera from frame to frame. So that the computer will be able to determine where the streets are flat or potholes. The purpose of this research is to create a program code that is able to determine the disparity from one frame to the next. With the help of recordings from two cameras, the disparity of any object captured on the two cameras will be calculated for each pixel. This data is used to compare the accuracy of the methods developed in this study. We use a program code developed to calculate the disparity of each frame in the video. The model developed in this study still needs to be studied in order to find a better method.

Dunia seketika dibuat gempar oleh pandemic Covid-19. Pandemi ini berdampak diberbagai sektor bidang diantaranya yaitu bidang pendidikan. Beralihnya sistem pembelajaran dari tatap muka menjadi tidak tatap muka. Salah satu kebijakan yang diambil oleh pemerintah agar pendidikan tidak terhenti yaitu pembelajaran secara daring. Dengan diberlakukannya pembelajaran secara daring ini menuntut siswa agar mandiri dalam belajar. Penelitian ini bertujuan untuk melakukan kajian literatur terkait dengan pentingnya pengaruh kemandirian belajar siswa pada pembelajaran secara daring. Metode penelitian yang dipilih dalam penelitian ini ialah metode SLR (Systematic Literature Review). Pengumpulan data dilakukan dengan mendokumentasi serta mereview semua artikel mengenai kemandirian belajar yang memiliki penelitian serupa pada laporan penelitian ini. Artikel yang digunakan pada penelitian ini sebanyak 15 artikel jurnal yang diperoleh dari Google Scholar dengan bantuan aplikasi publish and perish. Berdasarkan kajian literatur yang dilakukan bahwa kemampuan kemandirian belajar sangat diperlukan siswa di dalam pembelajaran terutama dalam pembelajaran daring. Kemandirian belajar ini memiliki pengaruh yang positif bagi siswa dalam pembelajaran.

This study aims to determine the development of mathematics education in Indonesia. The research method used is descriptive method, by presenting a description, clarification of a phenomenon and facts in mathematics. As well as library research (library research). By collecting several books, articles and opinions from experts regarding the development of mathematics and mathematics education which are then developed with various existing findings. The results showed that the development of mathematics was based on philosophy, because philosophy is the root of all human knowledge, both scientific knowledge and non-scientific knowledge. The historical development of mathematics, Babiliona mathematics refers to all mathematics developed by the Mesopotamians since the beginning of Hellenism. At that time the development of mathematics expanded to several countries such as Egypt, Greece, Arabia and India. The development of Mathematics Education in Indonesia is never separated from the history of the curriculum. The importance of mathematics in life is not surprising if mathematics learning has developed and adapted to the needs of the times. The development of mathematics learning in Indonesia is as traditional mathematics, modern mathematics, and modern mathematics.

The purpose of this study was to obtain information about learning activities for mathematics education during the Covid-19 pandemic in Asian countries (Indonesia, Japan and the Philippines). This study used a literature review method. Sampling was carried out using random sampling. In this study, related respondents were Asian countries including Indonesia, Japan and the Philippines. The Covid-19 pandemic has brought significant changes in the world of learning. The differences in these conditions are interesting to study to provide an overview of what is happening in the country and can be used as an evaluation in the future. This study was conducted through literature studies with various sources, both journals and online news. The selected countries are Indonesia, Japan and the Philippines. The selection is done randomly without any background representing the existing continents. Based on the results of the study, it is known the responses, strategies and obstacles that occurred in the education sector during the pandemic. The strategies, successes, and obstacles that occurred in each country were influenced by the readiness of infrastructure and human resources, as well as the initial conditions of the country before the pandemic.

ABSTRACT   This study was conducted based on low connection mathematical and creative thinking ability of students. The aim of this study was to determine: (1) whether the connection mathematical of students use Discovery Learning is different than Direct Instruction, (2) whether the creative thinking abilities students Discovery Learning is different than Direct Instruction, (3) the student answers use Discovery Learning variatever than Direct Instruction, (4) to responses the students used Discovery Learning very positive. This study is a quasi experimental research. The study population was all students of class VII SMP Swasta Ampera Batang Kuis consisting of three parallel classes. Of all students in grade VII students of two classes selected for the sample. The experimental class were treated Discovery Learning and control class were treated Direct instruction. In this research has developed several learning tools such as lesson plan and student activity sheets. The instrument used to collect data in this study are: (1) test the ability of connection mathematical, (2) test the ability creative thinking of students. The tests were used is in the form of a description. The test has been declared valid and reliable by the reliability coefficient of 0.814 and 0.878. Descriptive analysis is intended to describe the students' answers. Inferential analysis of data was done by analysis of covariance (ANACOVA). The results showed that: (1) The ability of connection mathematical of students used Discovery Learning is different  than Direct Instruction. This is evident from the results ANACOVA to F* = 14,559 is greater than Ftable = 4.052 with equation regression is for experiment class and  for control class (2) The ability creative thinking of students is different than Direct Instruction. This is evident from the results ANACOVA to F* = 9,113 is greater than Ftable = 4.052 with equation regression is  for experiment class and  for control class (3) The process of student answers by using Discovery Learning assisted open ended better than Direct Instruction (4) to responses the students positive.
