ANALISIS PROSES BERPIKIR SISWA DALAM PEMECAHAN MASALAH TERBUKA BERBASIS POLYA SUB POKOK BAHASAN TABUNG KELAS IX SMP NEGERI 7 JEMBER

Abstract. The research aims to describe the students’ thinking process of 9th grade of Junior High School in solving the open problem according to their capability in solving problem based on Polya’s solution step. Data analysis is done based on written test and interview techniques. The subject of research is students of IXA class at SMPN 7 Jember in odd semester academic year 2013-2014. The data of research are obtained by validation sheet, written test, and interview techniques. Students experience disequilibrium when they don’t understand about the qestion’s sentence and when she can’t determine the ways to solve the problem, also when she can’t determine the ways to check the result that has already gotten when she does the plans. Students experience assimilation when they can mention what is known and what is asked  from the problems immediately without reck of true or false, also when  they can determine the ways to solve the problems and when they are doing the computations. Students experience accomodation when they are quiet and confuse before they can determine the problem’s condition, also when she is doing the computation and when she is quite before she can determine the ways to solve the problem. Students experience assimilation and accomodation to reach the equilibrium phase. Key Words: thinking process, open problem, and Polya’s solution step

Kepraktisan dan Keefektifan Penggunaan E-LKPD Konteks Sosial Budaya Berbantuan Workbook GeoGebra terhadap Kemampuan Numerasi Peserta Didik pada Materi Limas

Numeracy is a person's ability to implement mathematics in the home, work and community environments. This research aims to measure the practicality and effectiveness of using E-LKPD in a socio-cultural context assisted by GeoGebra workbooks in improving students' numeracy skills in pyramid material. The type of research used was a quasi-experiment (Quasi-experiment) with research subjects 21 class VIII students at SMPN 1 Kalisat Jember. The practicality of E-LKPD is assessed from the results of student response questionnaires, while the effectiveness of E-LKPD is assessed from the results of students' numeracy ability tests. The use of E-LKPD is said to be practical if the average percentage of students' questionnaire responses is at least in the practical category, and effective if students' numeracy skills are at least in the medium category. Based on the practicality analysis, the results of the student response questionnaire regarding the use of E-LKPD obtained a percentage of 81.67% or were in the practical category. In addition, the use of E-LKPD shows an increase in students' numeracy skills on all numeracy indicators. This can be seen based on the results of the numeracy ability test which obtained an N-Gain score of 0.51 or at a medium effectiveness level. Therefore, the use of E-LKPD in a socio-cultural context with the help of GeoGebra workbooks is practical and effective for improving students' numeracy skills, especially in learning surface area and volume of pyramids

Pemberdayaan Bank Sampah Masyarakat untuk Mewariskan Budaya Lokal Berlatar Etnomatematika Geometri pada Siswa Sekolah Dasar Desa Tegalsari

One of the cultural behaviors of local wisdom that is starting to disappear is related to how manage the "garbage". Several communities still throw garbage out of place, such as in the river. On the other hand, the effects of this waste that was disposed of carelessly are very long-term for human health and also the environment. This culture is eventually emulated by their children and grandchildren who are still in school. For this reason, community awareness regarding waste needs to be directed, one of which is the management of a community waste bank. In Tegalsari Village, Ambulu Jember there is one Cipta Mandiri Waste Bank that has been operating for the last 3 years. The Waste Bank activity went quite well, but less than 20% of the community participated, especially young people and children who were less interested. So that the empowerment of the Waste Bank needs to be supported in order to be able to pass down the local culture of being aware of waste, especially for elementary school students through the socialization and education of ethnomathematics worksheets in the elementary school. The results of the activity showed that 78% of students wanted to take part in the waste bank around their homes and they enjoy learning with ethnomathematics worksheets about garbage

Partisipasi Mahasiswa dalam Pembelajaran Kooperatif Berdasarkan Lesson Study

  Partisipasi siswa memiliki peran penting dalam keberhasilan belajar. Partisipasi aktif siswa bisa mencapai tujuan belajar sehingga siswa bisa berprestasi akademik lebih baik. Partisipasi aktif dapat dipraktekkan dalam pembelajaran kooperatif dengan berdiskusi dalam kelompok atau kelas. Pembelajaran yang efektif dengan menggunakan pembelajaran kooperatif harus dirancang sebelum proses pembelajaran. Menurut analisis dan hasil refleksif, sebagian besar siswa di kelas telah mengikuti kegiatan belajar. Partisipasi aktif dikaitkan dengan berbicara atau memberikan pendapat, menjawab dan mengajukan pertanyaan untuk memberi ceramah atau memberikan komentar dalam diskusi di kelas. Di sisi lain, ada beberapa siswa yang pasif berpartisipasi dalam kegiatan belajar. Siswa tidak memberikan respon perilaku selama kelas. Siswa hanya perlu mendengarkan tanpa mencatat apapun. Kata Kunci : Partisipasi, pembelajaran kooperatif, lesson study &nbsp

KETERHUBUNGAN PELANGI KUAT (src) PADA GRAF (1 Spl-(Cn )) UNTUK 3 ≤ n ≤ 10

Let G be nontrivial and connected graph. A total-coloured path is called as total-rainbow if its edges and internal vertices have distinct colours. For any two vertices u and v of G, a rainbow u−v geodesic in G is a rainbow u−v path of length d(u,v), where d(u,v) is the distance between u and v. The graph G is strongly rainbow connected if there exists a rainbow u−v geodesic for any two vertices u and v in G. The strong rainbow connection number of G, denoted src(G), is the minimum number of colors that are needed in order to make G strong rainbow connected. The result shows for  1 Spl - (Cn) and 3 ≥ n ≥ 10 there exist a coloring where diam(G) = rc(G) = src(G) ≤ m and diam(G) ≤ rc(G) ≤ src(G) ≤ m with m is the number of path 1 Spl - (Cn). &nbsp
