Abstract

Abstract: The purpose of this study is to describe the steps for planning a project-based learning (PjBL) model in teaching Mathematics in grade X in the global context of Globalization and Sustainability and describe how students' mathematical reasoning abilities are after experiencing learning using the PjBL model. The type of research used in this research is design research. In this study, researchers designed a hypothetical learning trajectory (HLT) to teach Mathematics using the PjBL model in the context of planning to build a house. The stages of the research carried out were making the initial design, conducting design trials, and conducting retrospective analysis. The research subjects were six grade X students of private high schools in Yogyakarta who used the IB (International Baccalaureate) curriculum. The data collection instruments used by the researcher were field note sheets, written test sheets in the form of worksheets containing project questions, and structured interview sheets. From this study, the results obtained were that five students were able to use mathematical reasoning to complete the construction planning project of a house. Four students have been able to check the correctness of the solution and make conclusions. Keywords: globalization and sustainability, project-based learning, mathematical reasoning, project-based learning, house building projects. Abstrak: Tujuan dari penelitian ini adalah untuk mendeskripsikan langkah-langkah merencanakan model pembelajaran berbasis proyek dalam pembelajaran Matematika di kelas X pada konteks global Globalization and Sustainability dan mendeskripsikan bagaimana kemampuan penalaran matematis siswa setelah mengalami pembelajaran dengan menggunakan model PjBL.

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).

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

Berdasarkan tes yang dilakukan oleh peneliti pada siswa kelas XII di sebuah SMA di Yogyakarta, terdapat beberapa masalah terkait program linear, yaitu (1) siswa kesulitan dalam memodelkan masalah matematika ke dalam fungsi kendala dan objektif, (2) siswa terlalu terpaku dengan langkah pengerjaan yang diberikan guru, (3) siswa mengalami keputusasaan karena masalah program linear seringkali berupa kalimat panjang yang membuat siswa kebingungan. Penelitian ini bertujuan untuk mengetahui level kemampuan memodelkan siswa yang dilihat dari tes hasil belajar. Subjek penelitian adalah 31 siswa kelas XI IPS 1 di sebuah SMA di Yogyakarta. Data penelitian berupa hasil tes. Data tersebut diklasifikasi berdasarkan jawaban-jawaban yang sejenis lalu dianalisis berdasarkan indikator kemampuan memodelkan. Hasil penelitian menunjukkan bahwa dalam menyelesaikan soal tes nomor 1, 70,96% siswa berada pada level situasional, 22,58% siswa berada pada level referensial, dan 6,45% siswa berada pada level formal.Dalam menyelesaikan soal tes nomor 2, 93,59% siswa berada pada level situasional dan 6,45% siswa berada pada level formal.

Abstract

Pembelajaran Science, Technology, Engineering, Arts, and Mathematics (STEAM) merupakan pendekatan terintegrasi dalam pendidikan yang bertujuan untuk meningkatkan kemampuan berpikir kritis, pemecahan masalah, dan kreativitas siswa. Pendekatan ini menjadi lebih relevan ketika dikombinasikan dengan pembelajaran berbasis proyek dan kajian masalah yang berakar pada kearifan lokal, memungkinkan siswa untuk menghubungkan konsep-konsep ilmiah dengan konteks kehidupan nyata di lingkungan mereka. Untuk mendukung inovasi pembelajaran ini, sebuah program pelatihan khusus telah dirancang dengan tujuan memperdalam pemahaman guru mengenai pembelajaran STEAM melalui pendekatan proyek, meningkatkan keterampilan praktis dalam penerapannya, serta mengintegrasikan kajian masalah berbasis kearifan lokal. Melalui diskusi interaktif, tugas proyek kreatif, dan fokus pelatihan pada integrasi STEAM dengan kearifan lokal, program ini mendorong kolaborasi dan kreativitas di kalangan guru. Hasil pengabdian menunjukkan peningkatan signifikan dalam kemampuan guru untuk menerapkan STEAM dalam pembelajaran serta merancang proyek yang relevan dengan kearifan lokal, menciptakan lingkungan belajar yang kolaboratif dan menarik. Kemajuan ini tidak hanya meningkatkan motivasi guru dan kemampuan mereka dalam menyelesaikan masalah secara kreatif, tetapi juga meningkatkan kualitas pengalaman belajar siswa serta memberikan dampak positif pada pembelajaran matematika secara umum. Dengan integrasi STEAM dan kearifan lokal, pembelajaran menjadi lebih kontekstual, menarik, dan bermakna bagi siswa, mendukung perkembangan pendidikan yang lebih holistik dan kontekstual di Indonesia.

Abstract

The purpose of this study was to describe the elementary school teachers’ mathematical skills on the numbers, especially fractions after they have participated in a workshop. The teachers’ abilities which would be described by the researcher in this study were the ability to interpret, to order, to add and subtract, to interpret the meaning of the multiplication and division, to multiply and divide, and to make problems about fractions. In this paper, the author just only would describe the teachers’ mathematical skills in adding and subtracting two fractions, interpreting the multiplication and division of two fractions, multiplying and dividing two fractions. This capability was described base on the results of a test given to teachers after they have attended the workshop. Research subjects in this study were 17 Kanisius Demangan elementary school teachers at Yogyakarta. Of the 17 teachers, 16 teachers could add and subtract two fractions. Six teachers of 17 teachers could interpret what was the meaning of multiplication of two fractions. One teacher could interpret what was the meaning of division of two fractions. All of the teachers could divide two fractions. Sixteen teachers of 17 teachers could multiply two fractions.
