Abstract

Buku teks dapat mempengaruhi proses belajar peserta didik. Setiap kurikulum yang berlaku memiliki buku teks sebagai bahan ajar utama. Beberapa sekolah SPK di Indonesia mengadaptasi kurikulum yang diterapkan di Singapura. Penelitian ini bertujuan untuk mengetahui perbandingan konten materi dan penyajian materi pada buku teks matematika Indonesia dan Singapura pada materi SPLDV. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif komparatif. Perbandingan ini menggunakan buku teks matematika kurikulum 2013 kelas VIII Semester 1 dan buku teks Discovering Mathematics 2A (2nd Edition). Berdasarkan hasil analisis, kedua buku teks tersebut memiliki persamaan dan perbedaan masing-masing dalam setiap aspek dan komponen yang dianalisis. Pada cara penyajian materi, buku teks matematika Indonesia cenderung monoton dalam satu halaman secara padat diisikan oleh tulisan namun dalam pemilihan warna bervariasi. Sedangkan dalam buku teks Singapura, cara penyajian materi memanfaatkan tata letak yang bervariasi dengan menambahkan spot kecil (bubble) walaupun dalam pemilihan warna tidak terlalu bervariasi. Kelebihan buku teks Indonesia yaitu pemanfaatan masalah kontekstual saat memperkenalkan sebuah konsep, sedangkan pada buku teks Singapura masalah kontekstual hanya disajikan dalam latihan soal. Di sisi lain, buku teks Singapura memiliki kelebihan dalam hal integrasi pemanfaatan teknologi dan antisipasi miskonsepsi peserta didik.

Abstract

Integrating cultural context into teaching and learning activities can help students understand the material. However, the development of teaching materials that integrate local cultural contexts is still not widely practiced. This study aims to (1) describe the results of exploring the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon as a teaching material for mathematics, (2) determine students' responses to the mathematics teaching material resulting from the exploration of the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon, and (3) determine the difference in mathematics learning outcomes before and after using the mathematics module. This study applied the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). In the architecture of the Grand Mosque of Sang Cipta Rasa, concepts of two-dimensional shapes such as triangles and quadrilaterals were found, including squares, rectangles, trapezoids, and rhombuses. The expert validation results show that the developed mathematics module is highly feasible to implement, with percentages of content, presentation, and language feasibility aspects reaching 88%, 90%, and 89% respectively. Students' responses to the mathematics module were categorized as good (71%). Paired sample t-test results show that students' learning outcomes before and after using the developed mathematics module are significantly different, with higher learning outcomes after using the mathematics module compared to before its use. Thus, the mathematics module resulting from the exploration of the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon can be implemented in learning to improve mathematics learning outcomes.

Abstract

Merely providing the formula of area in the learning activity can impede students’ deep understanding of the concept of area. This study was a qualitative design research that aimed to develop a learning design by using the context of pixel art and grid paper to build students' knowledge of the concept of area measurement. There were three stages in this study, namely, preparation, teaching experiment, and retrospective analysis. The subjects of this study were 25 students of P3 (Primary 3) SD Global Inbyra School. However, the discussion focused on a group consisting of three students. The research subjects were given a mini lesson consisting of 2 meetings. It can be seen from the first meeting that the pixel art drawn by the students built on their initial measuring ability because they automatically notice that half square and half square make up 1 square. At the second meeting, students demonstrated their ability to estimate the number of squares (area) in an irregular picture. In the activity of making any shapes that have an area of 20 square units, students were aware that to find the area of the rectangle, they can use repeated addition which can be directed to the area of the rectangle (p x l).

Abstract

Several studies revealed that mathematics problems in textbooks, which were expected to encourage students’ reasoning and problem-solving skills, were still lacking. This study aimed to compare Pythagorean problems in Indonesian and Singaporean mathematics textbooks based on the cognitive level of Bloom's taxonomy, representation form, contextual feature, and response type. The data were collected through documentation and observation. The research results indicated that on the cognitive level, the C3-C4 level dominated the Pythagorean problems in Indonesian and Singaporean textbooks. Regarding representation form, Pythagorean problems in Indonesian textbooks used visual and combined forms, while Singaporean textbooks applied mostly combined forms. In contextual feature and response type, Pythagorean problems in Indonesian and Singaporean textbooks used non-application and closed-ended problems. Therefore, the result of this study is expected to contribute to the improvement of high-quality mathematics textbooks, which can compete internationally to support students’ learning.

Abstract

Many studies showed that teachers and prospective teachers have difficulty solving percentage problems. This research is a qualitative descriptive study that aims to investigate the prospective teachers’ strategies in solving problems on the topic of percentages. A total of 250 students majoring in Mathematics Education and Primary Education at IAIN Syekh Nurjati and IAIN Pekalongan were purposively selected to participate in this study. The results showed that only less than half of the participants (40.1%) could give the correct answer. Qualitative data on the strategies used by prospective teachers on the percent question show that (1) teacher candidates ignore the importance of the % symbol and consider the % symbol only as a unit of measurement, (2) teacher candidates ignore the essential role of the reference quantity in the percent question, (3 ) teacher candidates are not used to solving percent problems related to determining initial values before discounts and assume that any percent problem can be solved using multiplication or division.
