Abstract

This research is a qualitative research with a descriptive approach that aimed to describe students' mathematical problem solving ability in terms the level of mathematical logical intelligence on sequence and series topic. The subjects in this research were 32 students of class XI MIA. The data collection techniques used in this research were the method of test and interview. The results of the research showed that of the three levels of mathematical logical intelligence, research subjects have similarities, starting at the step of understanding the problem subjects expressed the purpose of the problem with their own language and sentence. Then in devising a problem solving plan subjects make a mathematical model. At the step of carrying out the plan, the subjects determine the variable values needed to find a solution to the problem, and at the end of the problem solving process, subjects looking back the steps used and the results obtained. Meanwhile, from the three levels of mathematical logical intelligence, research subjects have differences, that are at the step of understanding the problem where the information revealed by the subject of KLMT is more complete than the subject of KLMS and KLMR. Meanwhile, at the step of carrying out the plan the subject of KLMT in using problem solving procedure more clear and precise. While, the subject of KLMS was able to complete the completion plan whose answer was finally correct, although the procedure used was incorrect. Then, the subject of KLMR faced an obstacle in solving problems because the procedure used was unclear.

Abstract

This study aims to describe students' reasoning in mathematical problem solving on the topic sequences and series viewed by prior knowledge. This type of research is descriptive qualitative. By using purposive sampling technique, then, the research subjects were selected as many as 2 students of class XI MIPA, one of the high schools in Makassar. The data collection technique uses test methods and interviews then through three stages of data analysis, namely data reduction, data display, and drawing conclusion. The results showed that the reasoning process of high-ability students was to associate the concepts and knowledge they had, gather evidence by mentioning things that were known and asked, linking the formulas that were already owned with the problems faced, identifying concepts used to solve problems, revealing reasons in explaining the steps in carrying out problem solving. And drawing conclusions explains the concepts used from the problem. While the reasoning process of low-ability students is to mention things that are known and asked and students cannot make any conclusions after solving the problem. This is because students have not fully understood the problem, students are not used to correcting the answers obtained, and students are not used to writing final conclusions.

Abstract

This research is qualitative research with a descriptive approach, aiming to identify mathematical communication skills based on mathematical disposition in straight-line equation matter. The subject of this research are students of class VIII who represent each category of mathematical disposition that is high, medium, and low. Data collection techniques are done by giving questioner, tests, and interviews. The results showed that all students in each disposition category were able to write solutions systematically and were able to use mathematical symbols appropriately. However, DMR students are less able to understand the problem so there is a mistake in solving it. The difference in students' abilities can be seen from the ability to graph. DMT students draw graphs precisely. Meanwhile, DMS students draw inappropriate graphs. As for the subject, DMR students are not able to draw a solution graph of the problem.
