Abstract

Multiple Representation the ability to use several mathematical expressions. The purpose of this study is to describe the representations that appear when students interpret the signs. Descriptive explorative research is used in this study with three elementary school students in the Jember Regency. The research was conducted teacher’s teaching process, recording students 'activities using field note sheets, and analyszing the results of students' notes when constructing concepts. The research findings showed that the subject interpreted the sign by investigating the sign and then using some interpretations to express his mathematical ideas in the form of writing, pictures, tables, numbers, and symbols. This shows when interpreting the subject's sign using multiple representations. The representations used are image, verbal, and symbol representations. The results of this study are useful for teachers to stimulate children to make more than one representation when constructing a rectangle concept.

Abstract

Playing mathematics in early childhood based on semiotics gives children the opportunity to identify objects, look for signs and interpret signs so that they can solve problems in games. This study aims to describe semiotic based early childhood mathematics play activities. The research was conducted at the PAUD Lab School, Muhammadiyah University of Jember. The research subjects were 5 children from group B. The results showed that the activities of playing mathematics in early childhood based on semiotics were (1) collecting information related to semiotic-based math games, (2) looking for objects that matched the game and counting the number of objects found, (3) looking for relevant signs and signs. that are relevant to the number of objects found, (4) associated with signs of knowledge that have been previously possessed and look for all signs according to the objects found, (5) the child retells the play that has been done

Abstract

The background. of this research is due. to the impact caused by Covid-19. urge educators to carry out learning. distance that is almost unheard of. and the obstacles experienced by parents due to the pandemic. covid-19 is a tough economy. The learning house portal is an alternative for parents in helping their children to learn independently. at home at this time and the free use of the learning house can help parents, teachers and students. So the need for a prospective teacher perspective where one day will become a teacher in a school is an important point where opinions. from prospective teachers can be a point of view. for a change in the future. The results obtained that prospective teachers assess that the home study application can assist teachers in delivering learning materials during the. current Covid-19 period because in the learning house the material presented is clear, always follows the current learning developments, there are many features that can help and improve student learning. Not only in the form of electronic books, there are also videos and questions that students can practice immediately after studying the material. The conclusion. of the study is that. the perspective of prospective teachers argues that utilizing this application is a new way to increase student. learning motivation which by using this application makes it. easier for students. to find materials that they do not understand.

Abstract

This classroom action research aims to improve the ability of students' semiotic representations on material tangents to circles at SMP Muhammadiyah 3 Rambipuji. The preliminary study stated that 20% of class VIII students were able to represent their thinking results in the form of images and symbols. Ten grade VIII students became the research subjects. Data collection was carried out by field observations, student worksheets, and interviews. Data analysis with the stages of data reduction, data presentation, and drawing conclusions. Each cycle has 4 stages, namely, making plans, implementing action plans, making observations, and reflecting on research results. In this study, it was said to be successful if at least 85% of students obtained scores that exceeded the KKM limit. From the results of the implementation of cycle 1, 60% of students were able to represent the answers to the questions in the semiotic representation of the research subjects. Cycle 2 following the guided discovery learning method, indicates the development of semiotic representation abilities. Students find it easier to represent a problem in material tangent to a circle. So that the final value obtained has increased significantly is 90%. Keywords: Guided Discovery Learning, Semiotic Representation

Abstract

Penalaran matematis adalah kemampuan seseorang dalam berpikir logis untuk dapat menarik kesimpulan baru berdasarkan fakta, konsep dan sumber yang dianggap relevan. Penelitian ini bertujuan untuk mendeskripsikan penalaran matematis siswa dalam mengonstuksi konsep luas daerah persegi panjang. Penelitian ini merupakan penelitian deskriptif kualitatif. Sumber data berasal dari siswa kelas 4 salah satu SD swasta di Kabupaten Jember. Hasil penelitian menunjukan bahwa bahwa ketiga subjek telah mengonstruksi konsep daerah luas persegi panjang sesuai dengan indikator penalaran matematis yaitu menarik suatu kesimpulan secara logis pada kegiatan menemukan konsep luas daerah persegi panjang dengan menggambar persegi panjang dan menutupi seluruh permukaan persegi pajang dengan persegi satuan. Kegiatan memprediksi jawaban serta proses pencarian solusi dari suatu masalah, subjek memanfaatkan pola serta hubungan untuk membuat analogi, subjek menggunakan persegi satuan untuk menemukan konsep luas pesegi panjang. Pada indikator memberikan suatu penjelasan berdasarkan model, sifat-sifat, fakta, serta hubungan, subjek mengkalikan jumlah persegi satuan yang lebih panjang dengan jumlah persegi satuan yang lebih pendek yang dimisalkan sebagai panjang dan lebar persegi panjang. Pada tahap menganalisis suatu situasi serta membuat generalisasi, subjek menemukan rumus luas persegi panjang serta memeriksa kembali kebenaran dari hasil pekerjaannya untuk lebih memastikan lagi bahwa hasil pekerjaannya sudah dapat dibuktikan kebenarannya

Abstract

Kemampuan numerasi adalah keterampilan dalam menggunakan, memahami, serta menganalisis matematika untuk mengerjakan masalah dalam kehidupan sehari-hari. Penelitian memiliki tujuan mencari tahu perbedaan kemampuan numerasi matematika siswa dalam mengerjakan masalah TIMSS (Tren in Internasional  Mathematics and Science Study) dilihat dari gender yaitu pengkatagorian berdasarkan jenis kelamin. Metode penelitian ini menggunakan penelitian kualitatif deskriptif. Berdasarkan studi pendahuluan dari 28 siswa hanya terdapat 4 siswa yang mampu  mengerjakan masalah TIMSS. Oleh karena itu, subjek yang terpilih sebanyak 4 siswa kelas VIII E salah satu SMP  di kabupaten Jember provinsi Jawa Timur dengan 2 siswa laki-laki serta 2 siswa perempuan. Instrumen menggunakan 2 soal masalah TIMSS terkait pemecahan masalah di kehidupan sehari-hari, wawancara, serta dokumentasi. Selain itu, analisis data menggunakan pertama reduksi data, kedua penyajian data, serta terakhir penarikan kesimpulan, dilanjutkan pengujian kesahihan data menggunakan triangulasi sumber. Peneliti memilih subjek berlandaskan indikator kemampuan numerasi dari 4 siswa sebagai subjek penelitian tersebut menunjukkan kemampuan numerasi siswa laki-laki lebih unggul daripada siswa perempuan. Perbedaan kemampuan numerasi siswa dilihat berdasarkan 3 komponen indikator kemampuan numerasi. Perbedaan dikarenakan kemampuan penalaran siswa laki-laki lebih baik dibandingkan siswa perempuan dalam mengerjakan masalah di kehidupan nyata. Siswa laki-laki juga lebih unggul dalam pemahaman konsep mengerjakan masalah matematika. Kata kunci: Kemampuan Numerasi ; Masalah TIMSS ; Gender

Abstract

The purpose of this research is to describe students’ mistakes with semi-conceptual thinking types in solving mathematical problems in rectangular material. This type of research uses descriptive qualitative. Data collection techniques used written tests and semi-structured interviews. Subjects in class VIIE SMPN 7 Jember. Data analysis techniques use 3 ways, namely data reduction, data presentation, and drawing conclusions. The data validity technique uses the triangulation method. The results of this study are that many students make the same mistake due to a lack of reasoning ability to re-describe the information contained in the problem, and a lack of understanding of the concept so that dominant students just memorize concepts or formulas but cannot apply them to solve questions and do not check back answers to get answers. Correct result. Keywords: students’ error, semi-conceptual thinking type, Nolthing theory
