Analysis of junior high school students' errors in solving HOTS geometry problems based on Newman's error analysis

Abstract

Geometry is the most important material to be learned in school. But the fact that there are still many students often makes errors in resolving the problems of geometry. This research focuses on analysis students' errors in solving Geometry problems among junior high school students in every higher order thinking skills level. This research used a qualitative descriptive method aimed to identify the students' errors based on Newman's error analysis. The errors are associated with planes and related problems. Data collection was done based on students' work through test and interview. The errors were analyzed according to Newman's Error Analysis Model consisting of reading, comprehension, transformation, process skills, and encoding. The result revealed that the students having errors according to Newman's error analysis in every higher order thinking skills level, they are analyzing, evaluating, and creating.
