Analysis of the errors of the experimental fourth-grade students in solving word problems: Application of derivative based on the Newman's model in Semirom city

The main purpose of this research is to analyze the errors of the experimental fourth-grade students in solving word problems based on the Newman's error analysis model in Semirom city. The statistical population of this study included all the experimental fourth-grade students in Semirom in the academic year of 2016-2017, which were 160 people and among them, 120 people were selected through Cochran sampling and stratified random sampling method proportional to the volume. This research is applicative in terms of purpose, and is descriptive correlational, in terms of implementation. The data gathering tool was a standard and researcher-made test with 6 questions and a qualitative interview. The findings of this study showed that there is a positive and significant relationship between reading, understanding, converting, processing and encoding errors with students' performance. Correlation coefficient also showed a positive and significant relationship between conceptual and applicative structures, and there is a positive and non-significant relationship between conceptual and computational structures as well as, there is a negative and significant relationship between applicative and computational structures. The highest prevalence of student errors was in the first three phases of Newman's errors (non-mathematical literacy).
