This research is a developmental that the aims of the research is to produce teaching materials involving student worksheet characterized by REACT that valid, practical, and effective so that suitable to be used in learning process of sequences and series. Developing model that used in this research is Plomp\u27s developing model. This model consist of four phases, that are 1) Preliminary Investigation Phase, 2) Design Phase, 4) Realization Phase, 3) Test, Evaluation, and Revision Phase. Based on useful of validity test and practically test, overall the worksheets are valid and practical. It can be concluded that worksheet developed has good criteria so that suitable to be used in learning process of sequences and series and can increase student\u27s mathematics reasoning.: Penelitian ini merupakan penelitian pengembangan yang bertujuan menghasilkan bahan ajar yaitu Lembar Kerja Siswa berkarakteristik RME yang valid dan praktis sehingga layak digunakan dalam proses pembelajaran materi barisan dan deret. Model pengembangan yang digunakan dalam penelitian ini adalah model pengembangan Plomp yang terdiri dari tiga tahap yaitu 1) tahap investigasi awal, 2) tahap perancangan dan realisasi, 3) tahap tes, evaluasi, dan revisi. Berdasarkan analisis yang dilakukan diperoleh hasil, yaitu (1) tingkat kevalidan sebesar 3,7 dengan kriteria kevalidan sangat valid, dan (2) tungkat kepraktisan sebesar 3,5 dengan kriteria kepraktisan sangat praktis Jadi dapat disimpulkan bahwa LKS yang dikembangkan memenuhi kriteria baik dan layak digunakan sebagai alternatif bahan ajar matematika pada materi Barisan dan Deret yang dapat mengingkatkan tingkat penalaran matematis siswa

PROSES BERPIKIR MAHASISWAMATEMATIKA IKIP MATARAM DALAM PEMBUKTIAN KETERBAGIAN BERDASARKAN TEORI PEMROSESAN INFORMASI

Knuth (2002), Healey and Hoyles (2000) have studied on teachers and students’ concept on prooving. However, those studies did not yet discover on case “how does student’s thinking process on fragmentation proofing?.”The Information Processing Theory is one of the theories that focus on one’s thinking process. It is one of the members of cognitive learning type theory which digs detail and deep on the relationship between subdivisions of information since it has been received from its surrounding until it permanently saved in someone’s mind. The aim of this study was describing thinking process of ikip mataram students in mathematic prooving based on information processing theory

PEMBELAJARAN BERBASIS MASALAH UNTUK MENINGKATKAN PEMAHAMAN MATEMATIKA SISWA KELAS IX SMP

Based on observations found that students can not explain the concept that already taught and also can not give examples of problems in everyday life related to the concept being taught. It shows that students do not have the ability to be an indicator of understanding. Based on interviews found that teachers often use the problem-based learning, but in the implementation tends to the teacher centered learning. To solve the that problems then held action classroom  research that used problem-based learning. With problem-based learning can enhance an understanding that shown by student have an ability to correspond with the seven indicators of understanding. Problem-based learning that has been able to increase the students' understanding of mathematics consists of five stages, namely: a) Reading problems. b) Defining the problem. c) Find the idea "Brainstroming". d) Solve the problem. e) Share learning result. Learning has developed seven indicators of mathematical understanding, namely: interpretation, exampling, classify, summarize, inferring, comparing, and explaining. Each indicator score, then score is accumulated into a final score. Resulting 83% of all students, ie 29 of 35 the number of classes students have had a score of more than or equal to 75. In fact, there are two students who received a score of 100

Investigation of Contingency Patterns of Teachers\u27 Scaffolding in Teaching and Learning Mathematics

The purpose of this study is to investigate the patterns of scaffolding contingency in teaching and learning mathematics carried out by three teachers. Contingency patterns are obtained by examining the transcription from video recording of conversation fragments between teachers and students during the provision of scaffolding. The contingency patterns are drawn in three strategies: diagnostic strategy, intervention strategy, and checking diagnosis. The result shows that the three teachers expressed different interaction contingencies in their scaffolding activities: contingent dominant, non-contingent dominant, and pseudo-contingent. It is also found that the learning interaction performed by experienced teachers tends to be contingent dominant compared to novice teachers

The Linkage of Problem Solving Between Geometry and Algebra: What is Their Correlation?

PROCEEDING INTERNATIONAL CONFERENCE ON MATHEMATICS, SCIENCE, AND EDUCATION. SEMARANG STATE UNIVERSITY 2016This research aims to determine the students’ geometry ability through algebra, and to find out algebra ability in solving geometry problems. Students are required to work on the geometry questions and solve those using algebra. In vice versa, students are given the algebra questions in the nuance of geometry to be completed. Then, the students' answers are traced with interviews to determine the ability of students in answering the question of algebraic geometry, and vice versa. There are two subjects of research from junior high school students in grade th 9 . The study was conducted in four weeks. The solving problems used think a loud method and interviews which were conducted three times. After the interviews, it is found out that there is a correlation between the students’ ability of geometry and students’ ability of algebra. This statement againsts the (Atiyah, 2001; Charbonneau, 1996; Kvasz, 2005 )opinion which said that is not easy to connect geometry and algebra. In the solving problems, it was found that the subjects were using algebra and geometry modeling. Algebra and geometry has a very strong relationship. Students who have the ability to better geometry will have good algebraic ability as well, and vice versa
