Error analysis and its causal factors in solving mathematical literacy problems in terms of habits of mind

Abstract

Errors and factors causing mistakes in solving mathematical problems are important to be analyzed. This study aims to investigate the abilities, mistakes and factors that cause students to do mistake in solving mathematical literacy problems in terms of habits of mind. The study was conducted in junior high schools in Indonesia using a descriptive exploratory method. The participants are 3 students who have habits of mind limited, developing, and professional. Data were collected using mathematical literacy test and habits of mind questionnaire. All instruments used were tested for eligibility by two mathematics education experts. The conclusion shows that students who have habits of mind limited wrong in process skills that are wrong in interpreting and using different representations and expressing reasons, as well as communicating the results of interpretation and reason. While students who have habits of mind developing and proficient wrong in understanding that is wrong in combining different representations, symbols, connecting them to real situations, using a variety of limited skills and expressing various reasons, giving explanations and communicating with arguments. The factors causing errors are hesitation, inaccuracy, not doing calculations, unable to understand the information in the problem correctly, in a hurry in interpreting the problem without interpreting.
