Abstract The aim of this research is to describe the procedural fluency mathematic of students in solving algebraic operations. In this research, the procedural fluency based on two aspects: the students’ knowledge of procedural and the knowledge of using the procedural in the proper time to solve algebraic operations. The method of research used case study as the qualitative method. The subject of research were some junior high school students who lived around the researcher’s environment. The instrument of research consist of major instrument (the researcher) and supporting instrument (test and interview). Based on the result of research, the researcher found that the students’ knowledge of procedural fluency mathematic was not fluent enough. It is proven by the students’ answers. Most of them made mistake in answering the circumference of a rectangle and in operating unlike terms. Moreover, the students also confused when and how to use the procedural in solving algebraic operations. They were not consistent in operating like terms and unlike terms. In addition, they could not explain the correct reasons in using the procedural mathematic to solve algebraic operations.  Keywords: Procedural Fluency, Problem Solving, Algebraic Operations

Abstract

AbstractThis research aimed at analizing the ability of the students? mathematics representation on linear program materials after analizing the students? mathematics disposition and having cooperative problem solving model. This research was qualitative research with quantitative data as a tool to describe the students? achievement result. The research subject was the 8 students based on the lowest pre test result from the students of XI MIPA2.The research was conducted for once meeting. The delivering of lesson materials used cooperative problem solving model to the students with pedagogic treatment in the form of micro didactic. The observer who was from the mathematics education background of knowledge also stayed in class during the learning process. The data which had been collected were the implementation of cooperative problem solving, the students? learning activity, the students? ability on mathematics representation and disposition. Based on the research result, it could be concluded that cooperative problem solving model could increase the students?ability on mathematics representation and disposition. This could be proved by the increasing things as follow: First, the 8 students?ability on mathematics representation which was from the pre test average score 44,00 became 77,43 on post test. The total students who achieved the passing grade were 0 student from 8 students (0%) became 6 students from 8 students (75%) who completely passed the passing grade. Second, the students?ability on mathematics disposition was considered good/high. The average score increased from 54,50 (68,13%) became 61,00 (72,19%).Key Words            :  The Ability on Mathematics Representation, The students                           Mathematics Disposition and Cooperative Problem Solving Model

Abstract

AbstractMathematical literacy is an individual?s capacity to formulate, employ, and interpret mathematics in a variety of contexts. It includes reasoning mathematically and using mathematical concepts, procedures, facts, and tools to describe, explain, and predict phenomena. It assists individuals to recognise the role that mathematics plays in the world and to make the well-founded judgments and decisions needed by constructive, engaged and reflective citizens.This study aims to determine the level of students? mathematical literacy aspects of Content Space and Shape in junior high school 02 Sungai Raya. The answer in this study is to describe in detail in the form of a case study.The subjects of this study were 6 students of class IX A who were capable of upper, middle and lower with the object of their research mathematical literacy skills in the aspect of content space and shape in the three-dimensional materof cubes and beams. The results of the research on class IX A students showed that the two top-capable students were able to reach level 6 mathematical literacy aspects of content space and shape, two middle-capable students were able to reach level 3 mathematical literacy aspects of content space and shape, one lower-capable student was able to reach level 3 mathematical literacy aspect of content space and shape, and one lower-capable student is able to reach level 2 mathematical literacy aspects of content space and shape. This result implies that there are students who are able to reach above level 2 mathematical literacy aspects of space and shape content.Keyword:Mathematical Literacy, Level of Mathematical Literacy, Content Space and Shape

Abstract

AbstractThis research intends to explain and analyze the result of the application of RME structured scientific approach to develop student’s mathematical problem solving  abilities in junior high school. The research is conducted using Pedagogical Action Research in two cycles. The result shows (1) Student’s mathematical problem solving  abilities were weak before RME structured scientific approach implemented to the teaching, the percentage ability was 20,56%, average pre-test score was 20,81 and 0% for study completeness; (2) The use of RME structured scientific approach in teaching students was implemented accordingly to the plan that had been set, its six steps of the approach ran optimally; 3) Student’s mathematical problem solving  abilities increased significantly after the teaching, percentage average of mathematical problem solving increased to 79,08%, average test score increased to 82,72 and study completeness increased to 74,07%; (4) Implementation result of RME structured scientific approach can develop student’s mathematical problem solving  ability. It is proved by the average percentage of mathematical problem solving ability achievement increased by 58,53%, test score increased by 61,91 score and study completeness percentage inceased by 74,07 %.  Keywords: Scientific Approach, RME Approach, Mathematical Problem Solving Ability.

Abstract

 AbstractConceptual understanding of mathematic and mathematical connections became an important focus in the curriculum of mathematics. The population in this research were all students of IX SMP N 10 Pontianak, and the sample of the research was class IX D which selected by sampling. The form of research used was pre-experimental design with one group pre test-post test design. This research desig was devided into three phases, namely preparation phase, implementation phase, and data processing phase. Data collection techniques which used were test and non-test, the data have been obtained were analyzed by descriptive qualitative and quantitative methods. Generally, students? conceptual understanding and mathematical connection ability by using constuctivist approach learning has improved. Students? mathematical conceptual understanding at the begining belongs to medium category which percentage of 68.04%. This, students? mathematical connection ability at the begining before using constructivist approach belongs to low cateogry which was only 28,81%.The learning process was implented well, which was accordance with the lesson plan, and the results fell into a very good category. Students? mathematical conceptual understanding after learning process was categorized high which the percentage score of 87,78%. Meanwhile, students? mathematical connection ability after learning was categorized as high as 77.14%.Keywords: mathematical conceptual, mathematical connection, constructivist,                  mathematical knowledge.
