Mathematics has been a part of human cuIture for a very Iong time. Many assume that mathe matics is finaI, permanent, absoIute and unreIated to cuIture. Ethnomatematic is present to bridge be tween cuIture and education, especiaIIy in mathematics Iearning. One of the ethnomatematic objects is an artifact. Each area certainIy has its own cuIture, incIuding artifacts in the form of historicaI buiId ings that are characteristic of the area. Muaro Takus TempIe is one of the historicaI buiIdings in Kec. XIII Koto Kampar Riau. Muara Takus temple is an ancient religious artifact whose construction is still a mystery has the potential as a source of mathematical learning, but this must go through the exploration process. The purpose of this expIorative research with ethnographic approach is to ex pIore and expIore what mathematicaI concepts exist in Muaro Takus tempIe that can be used as a source of mathematics Iearning as weII as an effort to deveIop ethnomatematics as the basis of mathe matics Iearning. Through expIoration, interviews, documentation, Iiterature studies and observations in the muaro takus tempIe environment, it can be concIuded that there is a concept of square fIat buid (square, rectanguIar, paraIIeI trapezoidaI and irreguIar, rectangIe) and triangIe (right triangIe), circIe, refIection & diIatation, as weII as Iines and angIes on the structure of Muara Takus tempIe buiId ing. Iearning mathematics using ethnomatematic objects can enrich the mathematicaI appIications around students and can faciIitate students to understand abstract mathematics by using concrete ethnomatematic objects.

Berdasarkan pengalaman peneliti yang telah mengajar statistika selama 4 tahun, diketahui bahwa materi yang digunakan selama ini berupa buku teks yang sulit dipahami. Kemudian hasil wawancara dengan 9 mahasiswa juga diperoleh informasi, secara umum mereka menyatakan kesulitan dalam memahami materi yang ada di buku ajar. Pembelajaran ini menunjukkan bahwa buku ajar yang ada belum efektif dan efisien, serta berdampak pada hasil belajar yang diperoleh siswa. Penelitian ini bertujuan untuk mengembangkan modul statistik berbasis PjBL. Model pengembangan yang digunakan adalah model Plomp. Penelitian ini sampai tahap prototyping phase. Pada fase preliminary research yang dilakukan adalah menganalisis silabus, buku ajar, karakter mahasiswa, dan wawancara dengan dosen mata kuliah statistika. Sedangkan, fase prototyping, merancang bahan ajar dan divalidasi oleh dua validator. Teknik analisis yang digunakan adalah menghitung persentase produk yang dikembangkan. Hasil penelitian menunjukkan bahwa rata-rata persentase bahan ajar yang dikembangkan pada aspek didaktis, aspek isi, aspek kebahasaan dan aspek tampilan memiliki kriteria sangat valid. Sehingga dapat disimpulkan bahwa bahan ajar yang dihasilkan dalam penelitian ini adalah valid.

This study aims to produce a learning design for flat-sided geometry based on Rejang Lebong ethnomathematics to improve students' mathematical problem-solving skills that are valid, practical, and effective. It is motivated by the low ability to solve students’ mathematical problems. Mathematics learning carried out in schools should involve students actively. The research procedure is guided by the Plomp development design. The development model studied by Plomp is the initial investigation, development, prototyping, and research phases. In the initial investigation phase, the implementation of needs, curriculum, concept, and student analyses was implemented. In the prototype development phase, formative evaluation consists of self-evaluation, one-on-one evaluation, one-on-one evaluation, small group evaluation, and testing. Meanwhile, at the time of its application, it was tested on students of class VIII SMP to see the learning outcomes of the learning problem-solving abilities. Based on the development that has been carried out, it is obtained that the learning design of flat-sided geometry based on the Rejang Lebong ethnomathematics in the form of HLT, teacher's books, and books for class VIII SMP students are valid, practical, and effective.

The world of education is currently experiencing a very extraordinary event. The Covid-19 pandemic has a very broad impact on participants and educational institutions. Our education system must be ready to take the leap to transform online learning for all students and by all teachers. We are entering a new era to build creativity, hone student skills, and improve our quality with changes in systems, perspectives and patterns of our interactions with technology. Every individual who is in an educational environment must be able to use technology that can help the learning process, especially in schools. Likewise, with the implementation of teaching and learning at SMAN 3 Padang, the process of implementing learning in these schools currently cannot be carried out face-to-face in class as usual. Students take lessons from home. To find out the ability of teacher students, they must evaluate the learning that has been given. One of them is by giving the teacher online quizzes because face to face is no longer possible during the Covid 19 pandemic. Mathematics is one of the subjects considered difficult by students, especially for mastery of Olympic questions. For this reason, teachers are required to have creativity so that learning can be understood by students. Mathematics teachers are given training that supports this. The training that will be provided is in the form of making questions for quizzes which are carried out online. The students will solve these questions in accordance with the specified time. Teachers who take part in the training are expected to be able to motivate and evaluate students' ability to work on Olympic questions even though they are carried out online.

Students' problemsolving abilities can be improved in one way, namely by choosing the right mathematics learning model. One learning model that can be used is the problembased learning model. The aim of this research is to re-analyze the influence of the problembased learning model on students' mathematical problemsolving abilities by reviewing, summarizing data and analyzing several research results that have been published on Google Scholar as many as 14 articles using statistical methods. The type of research in this article is meta-analysis research. The research steps include data collection, coding, calculating the increase in problem solving abilities and effect size, and drawing conclusions. Based on the research results, the average effect size is 2.02 in the very large category. Based on the average effect size, it can be concluded that the problembased learning model influences students' mathematical problemsolving abilities.
