The aim of this study is to knowÂ theÂ differences of enhancement in mathematical problem solving ability (MPSA) between the students who received soft skill-based metacognitive learning (SSML) with the students who got conventional learning (CL). This research is a quasi experimental design with pretest-postest control group.Â The population in this study is the students of Junior High School in Pekanbaru city. The sample consist of 135 students, 68 of them are from the high-level school, and 67 students are from the middle-level school. The instruments are mathematical prior knowledge (MPK) test, MPSA test, instruction observation sheet, students journal about the lesson, and the guideline for interview. The data was analyzed using t-test and two-way ANOVA. The result of data analysis indicates: (1) overall, the enhancement of students' MPSA with SSML approach significantly is higher than those with conventional learning (CL); (2) there is no interaction between the learning approach (SSML and CL) with the school level (high and middle) toward the enhancement of MPSA; (3) there is no interaction between the learning approach (SSML and CL) with MPK (upper, middle, and low) toward the enhancement of MPSA.

The students' difficulty which was found is in the problem of understanding, drawing diagrams, reading the charts correctly, conceptual formal mathematical understanding, and mathematical problem-solving. The appropriate problem representation is the basic way in order to understand the problem itself and make a plan to solve it. This research was the experimental classroom design with a pretest-posttest control in order to increase the representation of visual thinking ability on mathematical problem-solving approach with contextual learning. The research instrument was a test, observation, and interviews. Contextual approach increases of mathematical representations ability increases in students with high initial category, medium, and low compared to conventional approaches.

This quasi-experimental study aims to determine the impact of realistic mathematics education (RME) on increasing Mathematical Problem-Solving Abilities (MPSA). The research design used was the non-equivalent control group with the subject population of all junior high school students in the city of Yogyakarta originating from low (C), moderate (B), and high (A) levels. From each school level, one school was taken then from each school taken an experimental class that received RME and one class of control who received regular learning (PB). The instrument used is in the form of two sets of equivalent MPSA tests. Data analysis uses the t-test and Anava. The results of the research were: (1) an increase in the MPSA of RME students was higher than the increase in the MPSA of PB students for all students and all levels of the school; (2) the highest increase in MPSA for RME students occurs at level A schools; and (3) there is no interaction between learning at school level in increasing MPSA.

Pemecahan masalah matematis yang berkaitan dengan materi pecahan adalah salah satu materi matematika yang sulit bagi siswa SD/MI. Penelitian ini bertujuan mengkaji pengaruh penggunaan media visual terhadap kemampuan pemecahan masalah matematis. Eksperimen dengan disain penelitian two groups pre-test post-test control group design ini menetapkan populasi seluruh siswa kelas V MIN Tungkop Aceh Besar dengan lima kelas paralel. Sampel diambil secara purposif dua kelas dari tiga kelas unggul yang ada di MIN tersebut, masing-masing satu kelas dijadikan sebagai kelas yang mendapat perlakuan (treatment) dengan jumlah siswa 35 orang dan satu kelas lagi sebagai kelas kontrol dengan jumlah siswa 34 orang. Di kelas perlakuan (treatment) pembelajaran pecahan dilaksanakan dengan menggunakan media visual dan di kelas kontrol pembelajaran pecahan dilaksanakan dengan cara konvensional. Data dikumpulkan dengan menggunakaninstrumen kemampuan pemecahan masalah matematis untuk siswa (tes esei).  Untuk pengujian hipotesis, data pretes dan postes kemampuan pemecahan masalah matematis, dan data peningkatan kemampuan pemecahan masalah matematis terlebih dahulu diperiksa persyaratan analisisnya berupa homogenitas dan normalitas. Pengujian hipotesis menggunakan uji-t pada taraf signifikansi 5%. Pengolahan data dengan menggunakan SPSS 17.0 for Windows telah diperoleh (1) Kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran dengan media visual lebih baik daripada kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran secara konvensional, dan (2) Peningkatan kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran dengan menggunakan media visual lebih baik daripada peningkatan kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran secara konvensional. Berdasarkan temuan ini, maka direkomendasikan kepada guru SD/MI bahwa ketika mengajar matematika khususnya topik pecahan, hendaknya menggunakan media visual sehingga siswa lebih mudah memahami konsep maupun pemecahan masalah matematis. Kata kunci: Pembelajaran dengan menggunakan media visual, pecahan,   pemecahan masalah matematis.

The facility layout design problem is concerned with determining the location of a number of facilities which optimises a prescribed objective such as profit, cost, or distance. This problem arises in many applications; for example, in design of buildings and in plant layout design. Most approaches for solving this problem are heuristic in nature and based on graph theoretic concepts. Graph theoretically, when the objective is to maximize profit, the facility layout design problem is to determine, in a given edge weighted graph G, a maximum weight planar sub graph. In this paper, a new heuristic based on graph theoretic concepts is presented. A comparative analysis based on 3600 random test problems demonstrates the value of this algorithm. Key words:Â Heuristic, maximum planar graph, computer, facility layout design.

One of skills which must be achieved by mathematics pre-service teachers is the basic skills of teaching mathematics. By having these skills, the pre-service teachers are expected to be able to become qualified teachers of the field they are going to have. However, there are still many mathematics pre-service teachers and mathematics teachers who havenât achieved good basic skills of teaching mathematics. This was one of many factors that cause studentsâ low achievement in math. This study aims at solving the problem by developing learning materials with Search-Solve-Create-Share strategy to enhance the pre-service teachersâ basic skills of teaching mathematics. The research method used in this study is modified research and development method. In a nutshell, this study provides a significant contribution towards research in the mathematics education field particularly in producing suitable learning materials to enhance the pre-service teachersâ basic skills of teaching mathematics.Â Keywords: Basic Skills of Teaching Mathematics, Learning Material, Search-Solve-Create-Share

Concept of Triangle: Examples of Mathematical Abstraction in Two Different Contexts Nurhasanah, Farida; Kusumah, Yaya S.; Sabandar, Jozua
International Journal on Emerging Mathematics Education IJEME, Vol. 1 No. 1, March 2017
Publisher : Universitas Ahmad Dahlan

Geometry has abstract notions to be learnt so that all those notions cannot be just transferred into studentsâ mind like a bunch of information that should be memorized. Students need to construct those concepts during their learning process. This process of knowledge construction can be considered as an abstraction process. This study aimed to qualitatively compare abstraction process of students who learned the topic of triangle in conventional method and in van Hiele model of teaching aided by Geometersâ sketchpad. Subjects of this study were junior high school students in grade 7. This is a qualitative study with grounded theory design. Data were collected through classroom observation, test, and task-based interview. Results of the study show that theoretical abstraction processes tend to dominate classrom with conventional method of teaching while classroom with van Hiele model of teaching aided by Geometersâ sketchpad accommodated empirical abstraction process of the students.
