Abstract

The Naek Dango Traditional Ceremony is a traditional ceremony of the Dayak Kanayat community in Merayuh Village, Air Besar District, Landak Regency, West Kalimantan Province. This study aims to explore ethnomathematics in the ceremony. Through ethnomathematics exploration, various mathematical concepts contained in the Naek Dango Traditional Ceremony can be identified, such as measuring volume and surface area. This research is a qualitative study with an ethnographic approach. The subjects of this study were the Temenggung and the Traditional Head of Merayuh Village. Data were obtained through active collection and analysis by the researcher. The collected data were analyzed through data condensation, data presentation, and continuous drawing of conclusions. The results of this study indicate that there is ethnomathematics in the Naek Dango Traditional Ceremony which is shown through the activities of calculating, determining locations, measuring, designing, playing, and explaining.

Abstract

The continuity of student learning in the midst of a pandemic is important. This encourages teachers to choose priorities in implementing distance learning. Teachers' efforts to accommodate inclusive learning in the midst of social and economic challenges and gaps in distance learning are a step in realizing student learning sustainability in the midst of a pandemic. The research conducted on 374 Mathematics teachers in Indonesia aims to determine the responses of Mathematics teachers to the continuity of student learning during the pandemic. These responses are seen from the teacher's priorities in distance learning and the efforts made in implementing inclusive learning during the pandemic. This research is descriptive research. Sampling was done using snowball sampling technique. Data collection was done by distributing online questionnaires. Several semi-open questions were asked which were then analyzed qualitatively using the Miles and Huberman framework and using descriptive statistics. The results showed that 81,18% teachers still prioritize the right of students to continue to acquire knowledge, by not pursuing the achievement of curriculum targets. To accommodate these student rights, teachers were encouraged to carry out inclusive learning. As many 100% teachers tended to apply the principles of flexible learning and 0,94% teachers collaborated with the student's parents by apllying the type of communication initiated by Epstein, namely by designing effective communication with parents through home visit activities.

Abstract: This research aims to determine the planning and implementation of the flipped classroom strategy in teaching compound probability material and determine the PCK profile of Mathematics Education students in practicing the flipped classroom strategy for teaching material at the high school level. The type of research used in this research is design research and qualitative research. The data analysis technique used in this research consists of three stages, namely: data reduction, data presentation, and drawing conclusions. Based on the results of the analysis carried out, it was found that: HLT for teaching high school level mathematics material using the flipped classroom strategy consists of four phases, namely: pre-phase, namely the researcher provides information related to the activities to be carried out; independent learning phase, namely the researcher provides a learning video regarding material on the probability of multiple events; synchronous learning phase, namely the researcher provides quizzes and practice questions for discussion; and the transfer phase, namely the researcher provides a project in the form of creating teaching modules to carry out learning practices; Undergraduate students' PCK in teaching high school mathematics material uses the flipped classroom strategy, namely 33.3% of students have PCK in the high category because they are able to fulfill some of the PCK categories. Then, the percentage of students who have PCK in the medium category is 53.3% and 13.3% of students have PCK in the low category. Keywords: PCK, HLT, strategy flipped classroom Abstrak: Penelitian ini bertujuan untuk mengetahui perencanaan dan pengimplementasian strategi flipped classroom dalam membelajarakan materi peluang kejadian majemuk serta mengetahui profil PCK mahasiswa Pendidikan Matematika dalam mempraktekan strategi flipped classroom untuk membelajarkan suatu materi ditingkat SMA. Jenis penelitian yang digunakan dalam penelitian ini yaitu penelian desain dan penelitian kualitatif. Teknik analisis data yang digunakan dalam penelitian ini terdiri dari tiga tahap yaitu: reduksi data, penyajian data, dan penarikan kesimpulan. Berdasarkan hasil analisis yang dilakukan diperoleh bahwa: HLT untuk membelajarkan materi matematika tingkat SMA menggunakan strategi flipped classroom terdiri dari empat fase yaitu: pra fase yaitu peneliti memberikan informasi terkait kegiatan yang akan dilakukan; fase belajar mandiri yaitu peneliti memberikan video pembelajaran mengenai materi peluang kejadian majemuk; fase pembelajaran sinkronus yaitu peneliti memberikan kuis dan latihan soal untuk diskusi; dan fase transfer yaitu peneliti memberikan proyek berupa membuat modul ajar untuk melakukan praktik pembelajaran; PCK mahasiswa S1 dalam membelajarkan matematika materi SMA menggunakan strategi flipped classroom yaitu sebanyak 33,3% mahasiswa memiliki PCK dalam kategori tinggi karena mereka mampu memenuhi sebagaian kategori dari PCK. Kemudian, persentase mahasiswa yang memiliki PCK dalam kategori sedang sebanyak 53,3% dan 13,3% mahasiswa memiliki PCK dalam kategori rendah.  Kata kunci: PCK, HLT, strategi flipped classroom   DOI: http://dx.doi.org/10.23960/jpmipa/v24i3.pp646-657

Abstract

This article emphasizes the importance of the PMRI and ethnomathematics for meaningful learning. In addition, low mathematical literacy is caused by students’ difficulties in connecting concepts with real-life contexts, while the integration of cultural contexts such as the Ramayana Ballet into PMRI remains limited. This study aims to (1) design and implement Hypothetical Learning Trajectory (HLT) with PMRI and LKPD with Ramayana Ballet Prambanan context to develop mathematical literacy skills, (2) describe students' mathematical literacy skills after experiencing learning on circle topic with PMRI. The type of research used is design research with stages (1) designing HLT, (2) implementing HLT, and analyzing students' mathematical literacy skills after experiencing learning. The data analysis technique used was reducing data, presenting data, and drawing conclusions. The results obtained were: (1) Mathematics learning in class VIII Pinisi effectively brought up all the characteristics of PMRI; and (2) Mathematical literacy skills of students in class VIII Pinisi after learning with the PMRI showed that students still had difficulties in several aspects, namely: (a) problem 1, writing complete information (level knowing), (b) problem 2, writing complete information, applying strategies and operations for problem solving (level applying), and (c) problem 3, providing mathematical arguments and assessing problem solving strategies and alternative solutions (level reasoning).
