Abstract

This research motivated by the desire of researchers to uncover the anticipation of student creative ideas Rigor’s level (accuracy) using the Maple program. The purpose of this research to analyze the anticipation of creative ideas by rigor level students (accuracy) in observing problems related to analytical geometry of space. The method used in this research is explorative qualitative research. Subject consists of three students with initials R1, R2, and R3. The results obtained that the subject of R3 tends to use the type of anticipatory analytics because they understand the problem what given well and use logical reasoning. While the subjects R1 and R2 more using the type of anticipatory explorative because it is still found trial and error activities in making algorithms of some parts of the form to be made. Students can create algorithms about what they see.

Abstract

Students with a rigor level of geometric thinking can analytically solve problems, yet the ability may not be readily observable. Thus, an example of how students solve problems merits explorations. Inspired by student’s problem solving, this study aimed to examine the student’s anticipatory profile in determining Papaya tree roots' dimensions. This qualitative research utilized tests and interview. Two tests were carried out: van Hiele geometric level grouping test for selecting the research participants and the report-based test for the actual project. Seventeen students took the van Hiele test, and one of them, who achieved the rigor level, was selected for the interview. Data obtained from the interview were then analyzed qualitatively. The study showed that students with a rigor level of geometric thinking anticipated analytically. The subject was able to explain a geometric problem systematically, starting from analyzing problems, clarifying detailss, to presenting arguments clearly and precisely. The findings in this study generate useful information for teachers who train their students to analyze a geometric problem correctly and adequately.

Abstract

Kesulitan siswa dalam menyelesaikan masalah integral kemungkinan besar dikarenakan kesalahan siswa dalam memahami soal. Tidak sampai disana saja, kesalahan memahami soal dimungkinkan karena antisipasi yang dilakukan siswa salah. Jika ada siswa dengan kemampuan tinggi, maka sebaiknya guru memperhatikan antisipasi yang dilakukannya sehingga siswa lain dapat belajar dari antisipasi yang dilakukan siswa kemampuan tinggi itu. Tes yang dilakukan kepada siswa NV ini merupakan tes integral dan hasil yang diperoleh yaitu karakteristik dari antisipasi ekploratif NV. Karakteristik antisipasi eksploratif yaitu (1) membaca soal lebih dari satu kali, (2) menemukan hal yang ditanyakan dan hal yang diketahui, (3) menguraikan soal secara rinci, (4) menggabungkan kriteria-kriteria yang diketahui, dan (5) memecahkan soal dengan mempertimbangkan alternatif penyelesaian Kata Kunci:Antisipasi, antisipasi eksploratif, integral

Abstract

Tujuan penelitian ini adalah untuk menghasilkan indikator 4C’s yang selaras dengan kurikulum SMA/MA yang digunakan di Indonesia yaitu kurikulum 2013 pada mata pelajaran matematika SMA kelas X semester 1 yang terdiri dari 3 bab yaitu: sistem persamaan dan pertidaksamaan linier satu variabel yang memuat nilai mutlak, SPLTV, dan fungsi. Kegiatan penelitian dimulai dari analisis masalah kurikulum di Indonesia dan menganalisis literatur kemampuan 4C’s menurut Partnership 21th Century Learning (P21). Kegiatan selanjutnya adalah merancang Indikator 4C,s yang selaras dengan kurikulum 2013 pada mata pelajaran matematika SMA/MA kelas X semester 1. Produk yang dihasilkan yaitu Indikator 4C’s yang selaras dengan kurikulum 2013 disajikan dalam vorum diskusi (kolokium). Kemudian produk tersebut direvisi berdasarkan saran dari peserta kolokium. Kegiatan terakhir yaitu membagikan produk yang valid kepada peserta kolokium sebagai panduan penyusunan rencana pembelajaran. Penelitian ini menghasilkan indikator 4C’s yang selaras dengan kurikulum di Indonesia yaitu kurikulum 2013.

Abstract

Creative thinking capability is a capability to deliver a new idea by varied means in solving problem. This research aims to describe creative thinking capability in solving square and rectangle problem reviewed by van Hiele’s thinking level of 4th grade students of SDN Kejayan 1 Bondowoso. This research type is descriptive research with qualitative approach. Data collecting method using test and interview. The used test is van Hiele’s geometry thinking test and creative thinking capability test related to square and rectangle. Research output shows that student at pre-visualization phase has less creative and sufficient creative thinking capability. Student at visualization phase, has sufficient creative and less creative thinking capability. Student at analysis level has sufficient creative thinking capability.

Abstract. The purpose of this study is to explore ethnomatematics in the activities of cocoa farmers to create the teaching materials for students in the form of the packages of test. The type of research was qualitative research with ethnographic approaches. The data collection method used were observation and interview. The research subjects were six people. The ethnomatematics included the activity of counting, measuring, and designing. This study focused on determining the estimated number of trees based on its distance and area by using stakes (patok), determining the fertilization model based on the fertilization time and the planting age, determining the number of workers based on the land area, and estimating yields. The emerging mathematical concepts were comparison and social arithmetic. Keywords: Ethnomatematics, cocoa farmers, culture

Abstract: A culture is born from the local community so as to produce works that become the characteristic of the culture. This culture is rooted and develops over time. One result of cultural work is Banyuwangi solok weaving. Education appreciates local culture in order to participate in preserving through the teaching and learning process. Weaving Solok Banyuwangi can be included as a medium for student learning in schools. Mathematics is one branch of science that studies symbols with logical reasoning. So there are estimates of the mathematical elements found in the Banyuwangi solok weaving motif. Mathematical elements found in Banyuwangi solok weaving include points, lines, triangles, quadrilaterals, hexagon, folding symmetry, rotary symmetry, congruence and similarity.
