Abstract

Algebra is one of concept that must be learned  by pupils. It is because the algebraic concept can be used in all areas of mathematics. One of the ways that is used to develop pupils' algebraic abilities is to think algebraically. While one of the ways  to develop pupils' algebraic thinking skills is to adapt pupils with mathematical problem solving. The purpose of this study is describing algebraic thinking profiles of junior high school pupils in mathematical problem solving. The description of pupils' algebraic thinking profiles is explained based on six indicators namely generalization, abstraction, analytic thinking, dynamic thinking, modeling and organization. This research is a qualitative study using test and interview methods. The research subjects consisted of one student in each student with high mathematical abilities, medium mathematical abilities and low mathematical abilities. The results showed that there were differences in algebraic thinking  of junior high school pupils  in solving mathematics in terms of mathematical abilities. Based on research data shows  that pupils with high mathematical abilities always think algebraically in each problems solving are given, while students with medium and low ability do not always think algebraically in each of problem solving.

Abstract

This study aims to describe the mathematical representation of students solving geometric problems based on sex differences. Both subjects have equivalent mathematical abilities based on the results of the math ability test. The results showed that the subject used mathematical representation in expressing his idea to solve geometry problems by using Polya's problem solving steps: (a) understanding the problem (b) devising the plan (c) carrying out the plan, and (d) looking back. The mathematical representations of female subjects in solving geometric problems are: understanding information and what is asked verbally and symbolically, carrying the plans visually in the form of geometric formulas and mathematics, carrying out planning by drawing, and manipulating mathematical models, at the stage of looking back the subject performed symbolic recalculation. While mathematical representations of male subjects in express their ideas to solve geometric problems by: understanding information and what is asked verbally, devising the plans in visual form in the form of images and then making mathematical formulas, carrying out the plans by manipulating mathematical models that has been made and looking back by doing recalculation and writing conclusions.

Abstract

The purpose of this study is to describe the relational thinking profile of students of Quitter-Visual, Camper-Visual and Climber-Visual type in solving mathematical problems based on Polya rules. To support the research, we use qualitative descriptive method involving 30 students of grade V SDN Sawahan I Surabaya. The data were collected using math skill test and interview. The results show that, Climber-Visual type students are able to apply all polya steps properly and correctly and Camper-Visual type students are only able to understand the problem and implement it while the Quitter-Visual type students are less able to understand the problem and abandon it. The result is caused by students' endurance in facing difficulties. The findings of this study can be used to map effective and efficient learning methods.

Abstract

This qualitative research aims to describe profile high order thinking  skill (HOTS) of Junior high school students? grade 8 in solving linear equation system problems based on kinesthetic and visual learning styles. In collecting data, mathematics ability test and learning style questionnaire aims to select students to be research subjects. Then, problem solving tests to determine the high order thinking skills and interviews were used to obtain data on students' high order thinking skills that were not obtained from problem solving tests. There are 3 (three) aspects of HOTS in this study which are analyzing, evaluating and creating. The results of the study show that in the aspect of analyzing, students with kinesthetic and visual learning styles can distinguish the information needed, know what is sought and know the relationship between information. In creating aspect, kinesthetic and visual aspects can know ideas, strategies used and can implement these ideas and strategies in solving problems. Whereas in the Evaluation aspect, kinesthetic uses a strategy in checking the truth in the answer but the visual does not use the strategy. Thus, it can be concluded that the differences of kinesthetic students and visual students lay on strategies used in checking the truth of the answers of the problem given.

Abstract

Reversibility is a mental process to construct two-way correlation from an initial condition to the result, and from result reverse to initial state. The concept of reversibility is a key aspect of the development of mathematics which is often problema for student. Reversible thinking is the primary requirement to solve mathematical problems. The importance of reversibility is one of the reasons in this study. The aimed of this study was to identify student?s reversibility in solving algebaic problems. The subject consisted of 32 junior high school student?s, especially at the eight grade. In this qualitative study, data were collected by a reversibility task and interview. The reversibility task contained simple equation. The result of this study indicate that reversibility aspect of solving algebaic problem can identified were reciprocity and negation, in this case reciprocity was more prominent. This could be seen from 32 junior high school students were able to make equation according to the reversibility aspect, but there were only five students are be able to fulfill two aspect of reversibility, described as negation and reciprocity, the others only fill reciprocity. The result showed that the problem related reversibility on junior high school still exist, especially in the aspect of negation.

Abstract

Spatial ability has been recognized as a significant human skill involving the retrieval, retention, and transformation of visual information in a special context. One type of spatial ability is the skill of performing mental rotations. Mental rotation is is the ability to rotate two or three-dimensional objects rapidly and accurately in the mind. . In other words, by way of rotating objects mentally and thereby solving problems related to space, this test includes the limit of reaction time and the rotation angle, both of which are mutually related to the degree of difficulty. The subject of this research comes from 9th grades students at junior high school in Surabaya were selected from purposive sampling. The volunteer student with high ability in mental rotation based from differences gender were selected from mathematic ability task and interviewed. The result showed that high ability male students able to visualize the result of two-dimensional wake rotation such as right triangle rotated as 45°, 90°, 180° and 360. While high-ability female students are still somewhat difficult to visualize the result of two-dimensional rotational objects such as triangle too but had difficultness when rotated as 45°.
