Abstract

The study aims to find out pseudo-thinking in solving mathematical problems. The methods used in this study are qualitative descriptive. The research subject is junior high school students using the purposive sampling technique, the students are grouped into three ranks i.e. low, medium and high rankings which each ranked 3 students as respondents. The total number of respondents was 9 students. Data collection techniques using tests, interviews, and documentation. From the results of the study gained that: 1) students who are ranked low in solving mathematical problems are experiencing pseudo-analytic or pseudo-false, 2) students who are in the moderate level also experience pseudo-analytic or pseudo-incorrect, 3) students who are in high ranking experience pseudo-analytic and pseudo-4) students who experience pseudo-thinking choose procedures using their own reasoning and convince it as a correct understanding , so there is no attempt to re-examine what he has done

Abstract

This research aims to find out the description of Mathematic Combinatory Thiking Ability of the Students. This is a descriptive qualitative research. The subject of the research was the students of Grade XI.MIA-5 SMAN 5 Purwokerto. The technique of the data collection in this research was by test, interview and documentation. The result of the students’ mathematic combinatory thinking ability was grouped in 3, namely the high, middle, and low. Each group was taken 3 as the respodents. The result of the research showed that mathematic combinatory thinking ability of the high could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly, and able to solve more than one combinatory problem in one single mechanism. The students’ mathematic combinatory thinking ability of the middle could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly. Then, the students’ mathematic combinatory thinking ability of the low could only understand the problem faced and started to find the possibility of answering the correct answer. Keyword: Mathematic Combinatory Thinking Ability
