Abstract

The objective of this study is to characterize the mathematical problem-solving capabilities of 10th grade students at SMA Negeri 1 Batuputih, based on their Adversity Quotient (AQ). This research used a qualitative approach. The subjects in this study consisted of six students of class X SMA Negeri 1 Batuputih who were determined based on AQ criteria with purposive sampling technique. The instruments used were an Adversity Quotient (AQ) questionnaire, a description test, and interview guidelines that had been properly validated by experts. The data collected were analyzed with the stages of data condensation, data presentation, and conclusion drawing and verification. The results showed that: (1) Subjects with climber-type AQ can solve the three stages of problem solving by Polya quite well, namely: the stages of understanding the problem, developing a plan, implementing the plan, however, they have not been able to check the correctness of the results completely; (2) Subjects with camper-type AQ have not been able to understand the problem completely, thus, having difficulty in developing a complete plan; and (3) Subjects with quitter-type AQ cannot understand the problem, and do not have a picture of solving the problem.

Abstract

This study aims to describe the errors made by students in mathematics word problem of proportion topic based on Newmans’ criteria in term of student learning styles. The data collection techniques used are learning styles questionnaire, diagnostic tests and interviews then through three stages of data analysis that are data condensation, presentation, and conclusion. The result of the research showed that the indicator of the direct proportion errors made by (1) subject of visual learning style is encoding errors, (2) subject of auditory learning style are reading errors, comprehension errors, transformation errors, process skill errors and encoding errors, and (3) subject of kinesthetic learning style are comprehension errors, transformation errors, process skill errors and encoding errors. In addition the indicator of the inverse proportion errors made by (1) subject of visual learning style are transformation errors, process skill errors and encoding errors (2) subject of auditory learning style are transformation errors, process skill errors and encoding errors, and (3) subject of kinesthetic learning style are transformation errors, process skill errors and encoding errors.

Abstract

This research is a qualitative research with the aim of describing mathematical communication skills in terms of the level of mathematical ability of students in Senior High School to an understanding of trigonometric equations. There were 3 research subjects namely one student that has high-ability (KMT), one student that has medium-ability (KMS), and one student that has low-ability (KMR). The instruments used in data collection are written questions and interviews. This research shows that student with high mathematical abilities is able to write in detail the flow of problem solving, explain the solution correctly and systematically and be able to draw conclusions appropriately. In addition, students are also able to provide logical reasons for the steps to resolve the problem. Show that can be said that students are able to communicate the results of their work in detail. Student with moderate mathematical abilities still has errors and errors in solving problems, the reasons used in the settlement are sometimes still not correct and the writing of conclusions is still not in accordance with the command questions. So that it can be said that student is still unable to communicate the results of their work in detail. Student with low mathematical abilities tends to write down problem solving briefly, has not been able to draw conclusions from the solutions made and also has not been able to provide an explanation of the solutions made. This shows that student has not been able to communicate the results of their work.

Abstract

This research aims to analyze students’ errors and the factors that cause students’ errors in solving problems of two-variable linear equations system based on Newman’s stages viewed from initial mathematical ability. This research is qualitative research with a descriptive approach. The subject of this research is students grade IX that consists of six students which two people for each level of initial mathematical ability. Data collection techniques in this research are test and interview. The research instrument was used, namely the initial mathematical ability test, a diagnostic test of a two-variable linear equation system, and interview guidelines. The data analysis techniques in this study include the condensation of data, the presentation of data, and the verification or drawing of conclusions. The result shows that: (1) Students with high initial mathematical abilities make mistakes in processing skills and writing in answers; (2) Students with medium early mathematical abilities are making mistakes in understanding questions, transforming questions, processing skills, and writing answers; (3) Students with low initial mathematical abilities make errors in reading questions, misunderstanding questions, transformation, processing skills, and writing answers. The factors that most often cause students' errors in solving the Two-Variable Linear Equations System material problems are students being less thorough and hastily working on the questions, have not mastered the prerequisite material, and as the result of previous mistakes.
