Abstract

A magic square of order n is an n by n matrix with distinct nonnegative integer with the property that the sum of the numbers in each row, each column and the main and back diagonals is same. This sum is the magic sum. In this paper we will discuss some methods to construct the first n2 positive integers for magic squares. The first method that will be established is Latin square Decomposition. Some magic squares can be derived directly with this method. Other methods that also will be discussed are trial and error method, De La Loubére construction, Strachey construction, and product construction. Finally we conclude that for all positif integers n, n ¹ 2, it can be constructed a magic square of order-n

Abstract

AbstrakBanyak sekolah yang belum memahami dan siap menerapkan kurikulum prototipe dan belum pernah menerapkan pembelajaran berbasis proyek. Tujuan penelitian ini difokuskan pada cara pandang dan kinerja guru matematika dalam mempersiapkan implementasi kurikulum prototipe. Penelitian ini menggunakan metode penelitian kualitatif dengan data yang diperoleh dari observasi dan wawancara. Selanjutnya, analisis data dilakukan dengan menunjukkan bukti kinerja dan naskah wawancara tentang perspektif guru untuk meninjau kesesuaiannya dengan penelitian sebelumnya. Hasil penelitian menunjukkan bahwa kinerja guru matematika selama penyusunan modul pembelajaran berbasis proyek adalah kesulitan dalam menyusun topik proyek dan mengoperasikan aplikasi komputer sehingga tampilan modul menjadi menarik. Perspektif guru terkait dengan kurikulum prototipe adalah adanya tantangan dalam mengembangkan modul pembelajaran berbasis proyek dimana proyek tersebut merupakan integrasi dari beberapa mata pelajaran. Penyusunan soal jenis AKM juga dinilai sulit dan produk penilaian dengan soal jenis AKM yang dihasilkan guru antara lain soal pilihan ganda, menjodohkan, esai pendek dan esai lengkap. AbstractMany schools do not understand, are ready to implement the curriculum prototype, and have never implemented project-based learning. This research aims to focus on the perspective and performance of mathematics teachers in preparing the curriculum prototype implementation. This study uses qualitative research methods with data obtained from observation and interviews. Furthermore, data analysis was carried out by showing evidence of performance and interview scripts about the teacher's perspective to review its suitability with previous research. The results showed that the mathematics teacher's performance during the preparation of project-based learning modules was the difficulty in compiling project topics and operating computer applications so that the module's appearance became attractive. The teacher's perspective on the curriculum prototype is that there are challenges in developing project-based learning modules where the project integrates several subjects. The preparation of AKM-type questions was also considered problematic, and the assessment products with AKM-type questions produced by the teacher included multiple choice questions, matchmaking, short essays, and complete essays.

Abstract

Learning in post-pandemic schools is experiencing a transition where students are used to operating gadgets for learning while teachers are inexperienced in developing application-based media. In addition, students are also not used to solving AKM types of questions. Therefore, this study aims to describe the development of learning media using codular applications to identify student responses in solving AKM questions contained in the media. This study uses a 4D development model with a limited stage of disseminating development results. The test subjects of this study were junior high school students where the test data obtained was analyzed qualitatively from the response results after operating the media. The results of the research show that at the defining analysis stage it is done by distributing online questionnaires to teachers. The results of the questionnaire show that schools need learning media so that mathematics learning is integrated with technology. The learning media should be practical to learn and access anywhere and anytime. This resulted in the selection of learning media to be application-based and accessible through student gadgets. Next, at the design stage. Next, look for references about using Kodular applications and designing media. The results of the validation show that the media is feasible to be tested on students. Media trials as a development stage show a variety of responses. The results of identifying student responses based on questionnaires show that students like application-based learning media because they are easy to operate and practical to use for learning on various occasions. Students also stated that all navigation buttons function properly and the layout is consistent. The dissemination stage was carried out by training teachers in making application-based learning media and the result was that 2 teachers produced media.
