This study aims to generate trajectories of students in learning by using a comparison worth growing terraced paper of form informal toward formal shape. The method used in this research is the research design consisted of three stages, namely the preliminary, design experiments and retrospective analysis. In this study, a series of learning is designed and developed based on the notion of the learning process and approach PMRI. This research was conducted in SMP PGRI 1 Palembang by involving students in grade VII.2 totaling 30 students. This research produces Learning trajectory (LT), which includes three activities namely 1, activity starts from drawing two wake up the same but different size, measure each side at the wake and determine the corresponding sides to determine the ratio. Activity 2, the activity determines the relations between the two ratios to determine whether the two ratios is a comparison worth or not. Activity 3, resolve issues relating to the comparative worth of daily life-today. Results of the experiments showed that a series of learning activities that have been done to help improve students' understanding of learning valued comparison.

Percent is often used in a variety of media in everyday life. Percent begins to be studied at theelementary level. Students are more or less know about percent, but they are often difficulties inpercent problems. This study aims to support students’ understanding in learning percent using a grid10 x 10 and Indonesian Realistic Mathematics Education (PMRI) approach. The method used isdesign research of type validation studies. Design research consisted of three stages: preliminary,design experiments and retrospective analysis. This research was conducted in SD Negeri 23 OKU byinvolving students of class V. The data were collected through video recordings, students’ work,interviews and then analyzed the data mostly in qualitative ways. The results of this study are learningtrajectory that consists of 3 activities and shows that the grid of 10 x 10 with PMRI approach can helpstudents understand the learning percent.

This research is a descriptive study that aims to describe the ability to understand mathematical concepts in grade 12 7 in SMA 1 Palembang through learning assisted Grapher application on android. The subjects of this study consisted of 30 students. The instrument used was observation and test. Observations were used to collect data about learning and tests were used to see the ability to understand students' mathematical concepts. The results of the study concluded that the ability of students' understanding of rational function material, limitless to algebraic functions and infinite limits on categorized trigonometric functions was quite good. In the material of rational function, students were misconstrued due to being trapped in images that appear to be congruent. Even though the pictures were not congruent. Still related to the material of rational function, the presentation of a picture that was not right in terms of scale and form of sketches caused students to misinterpret the problem and make conclusions. Specifically for infinite limit material for both algebraic and trigonometric functions, the low scores of students on the concept comprehension tests were caused by students being less careful in calculating.

Penelitian ini adalah penelitian deskriptif yang bertujuan untuk mengetahui proses berpikir matematis aspek abstraksi siswa kelas XI menggunakan pembelajaran creative problem solving pada materi barisan dan deret aritmetika. Subjek penelitian ini adalah 31 siswa kelas XI MIPA 2 SMA Negeri 4 Palembang. Proses pembelajaran disesuaikan dengan langkah-langkah pembelajaran creative problem solving. Pengumpulan data dilakukan dengan tes dan wawancara. Soal tes terdiri dari 3 soal uraian. Tes dilakukan untuk mengetahui proses berpikir matematis aspek abstraksi siswa yang muncul saat mengerjakan soal. Wawancara dilakukan untuk menggali alasan siswa dalam menyelesaikan soal tes. Berdasarkan hasil penelitian dapat disimpulkan bahwa setelah dilakukan pembelajaran menggunakan CPS, tidak semua tahapan proses berpikir matematis aspek abstraksi siswa ditunjukkan secara bersamaan dalam menyelesaikan masalah untuk setiap indikator berpikir matematis aspek abstraksi. Proses spesialisasi dan observasi pola ditunjukkan ketika siswa mengidentifikasi masalah, membuat pola dan menyusunnya menjadi sebuah strategi penyelesaian masalah. Tetapi pada proses memeriksa konjektur, siswa masih perlu dilatih untuk membuat pembuktian dan penyelesaian dengan cara yang beragam agar terbiasa dalam memeriksa dugaan penyelesaian masalah.

AbstractThis research is aimed to increase students higher order thinking skill in mathematics learning using probing-prompting learning technique. This research is descriptive research with 21 students of X.C class at SMAN 02 Indralaya Utara as the subject. Learning process is according to the characteristic and steps of probing-prompting learning technique. Techniques for collecting data are test which includes of three problems and interview to obtain additional data. According to the results of research, it’s obtained that representation of students’ higher order thinking skill in problem based learning on X.C class at SMAN 02 Indralaya Utara is good with this details: percentage of students who have higher order thinking skill with category excellent is 19%. Then, 38,1% have higher order thinking skill with category good; 28,6% have higher order thinking skill with category medium; 14,3% have higher order thinking skill with category bad; nothing shave higher order thinking skill with category very bad. Indicator of analyzing have the highest percentage with 85,7%. Then, indicator of evaluating have percentage 71,4%, and indicator with the lowest percentage is creating with 44,6%.Keywords: Higher order thinking skill, probing-prompting technique

ABSTRACTGraph has a concept of tree. Tree is a connected graph which is not consist cycle. Concept of tree is an important concept because it can be used to support application of graph in any variation of science. Besides, spanning-tree is a tree in graph with every point on graph. Every graph can be formed at least there is one spanning tree. The problem of this article is how to determine the sum of spanning-tree in directed graph with matrix in-degree yang menggunakan teorema: the value of the cofactor of is equal to the number of arborescence in rooted at the vertex . Arborescence in is spanning arborescence.Keywords : spanning-tree, directed graph, matrix in-degreeABSTRAKGraf memiliki konsep tree (pohon). Tree merupakan graf terhubung yang tidak memuat siklus. Konsep tree merupakan konsep yang penting karena konsep ini dapat digunakan untuk mendukung penerapan graf dalam berbagai bidang ilmu. Sedangkan spanning-tree adalah sebuah pohon pada graf yang memuat semua titik di . Dari setiap graf dapat dibentuk paling sedikit sebuah spanning-tree. Permasalahan dalam artikel ini adalah bagaimana menentukan jumlah spanning-tree pada graf berarah dengan matriks in-degree yang menggunakan teorema: nilai kofaktor dari adalah sama dengan banyaknya arborescence pada dengan titik sebagai root. Arborescence pada juga merupakan spanning arborescence.Kata kunci: spanning-tree, graf berarah, matriks in-degree

This study aims to determine the students' mathematical reasoning ability in presenting data using Pendidikan Matematika Realistik Indonesia (PMRI). This type of research is descriptive qualitative research. The subjects in this study were 5 students in grade 7. The data collection technique used in the study was a description test which consisted of 5 questions, and interviews. The results obtained after carrying out the research were that there were 2 students who gave rise to all indicators of the student's ability, the other 2 students were quite good at mathematical reasoning abilities. However, the student's mistake was not paying attention or reading the questions carefully and thoroughly. So that the student does not solve the problem in accordance with what was instructed in the question. In addition, there is one student who uses reasoning that focuses on solving problems based on what he observes. These students do not work in accordance with what the questions are instructed to do and do not carry out the mathematical process in working on the questions.
