ANALISIS KESALAHAN SISWA DALAM MENYELESAIKAN SOAL CERITA PENJUMLAHAN DAN PENGURANGAN BERDASARKAN TEORI NEWMAN

Abstract

Mathematics is the study of number concepts and counting operations, such as
addition and subtraction. In learning mathematics, student errors are often found,
especially in story problems that involve understanding and applying these
operations. The purpose of this study was to analyze student errors in solving
addition and subtraction story problems based on Newmans theory. This study
used a qualitative descriptive approach with a population of 27 students of grade I
SD N 1 Dersalam and the sample in this study were 3 students who showed the
lowest scores in the diagnostic test. Data analysis techniques according to Miles
and Huberman were carried out through observation, documentation, and
interviews. In this study, researchers used Newmans Theory to analyze students'
errors in solving mathematics story problems. The stages include five stages that
are the basis of student errors, namely reading, understanding, transformation,
process skills, and writing the final answer. The results of the analysis showed that
each of the 3 students experienced different errors, including inaccuracy in
understanding the story problem, difficulty in transforming the problem sentence
into mathematical form, and lack of accuracy in compiling and writing the final
answer. The errors were caused by limitations in reading skills, students
difficulties in transforming the problem into mathematical form, and students lack
of understanding of the story problem.
