Diagnosis Of Mistake Complete Mathematical Story Problems Class V Students Of Elementary School Tanete Riattang Barat District Bone Regency

Abstract

The problem in this study is about students' mistakes in solving mathematical story problems. The formulation of the problem studied is 1) What mistakes do students make at each step in solving a story problem ?, 2) What is the level of student mistake in solving a story problem ?, 3) What causes students to make mistakes in solving a story problem ?, and 4) Is the level of student mistake significant in solving story problems? The purpose of this study is to: 1) Know what mistakes students make at each step in solving story problems, 2) Obtain an overview of students' mistake rates in solving story problems, 3) Know the causes of students making mistakes in solving story problems, and 4 ) Knowing whether the level of student mistake is significant in solving story problems. The approach in research is a quantitative approach and the type of research is ex post facto. The variable that was investigated was a single variable, namely students' mistakes in solving story problems. The population in this study were all fifth grade students of SD Tanete Riattang Barat District, totaling 626 people from 3 clusters consisting of 13 schools and research samples were fifth grade students from schools selected by purposive cluster random sampling technique, namely SDN 22 Jeppe'e, SD Inpres 12/79 Bulu Tempe, and SD Inpres 10/73 Watang Palakka as many as 137 students consisting of 72 men and 65 women. Data collection techniques used were tests and interviews. The data analysis technique used 1) descriptive statistics, which were calculating the average score and percentage of students' mistakes, and 2) inferential statistics using one sample t-test. The results showed 1) The types of mistakes made by students were not complete writing down answers, wrong in writing answers, and not writing answers, 2) The level of students' mistakes in completing story problems at each step of solving math story problems was in the high category, 3) The cause of students making mistakes is students do not understand the purpose of the problem, not careful in writing answers, accustomed to abbreviating answers, lack of understanding and wrong way of working on problems (incorrectly using formulas, incorrect concepts, and wrong operations), and 4) The level of student mistakes is significant in solving math story problems.
