Students’ Error Analysis in Solving Word Problems in Exponential Number Topic Based on Newman’s Error Analysis (NEA) Theory

In mathematics, students usually experience errors in solving word problems. Previous studies found that students’ skills problems were not good enough. Therefore, exploring to be a consideration designing efforts minimize these is necessary. This study aimed describe the made by exponential numbers based on Newman’s theory. Based view, there are five stages of student error: reading errors, comprehension transformation process skill and encoding errors. research descriptive qualitative involving grade nine with two each category, namely high, medium, low levels mathematics ability. The data collection was conducted through documentation interview. study’s analysis involved reduction, display, conclusion drawing. analysis, it could concluded that: 1) high mathematical ability still committed transformation, skill, stages, 2) moderate experiencing but one subjects also at 3) experienced quite lot problems, comprehension, stage. These findings used as planning teaching learning activities occurrence similar various
