Differences in Mathematical Reasoning Ability of Students in Secondary High School

Abstract

This study aims to find differences in students 'mathematical reasoning abilities based on the frequency of correct answers to questions that measure students' mathematical reasoning abilities of junior high schools in 2014-2016. Mathematical reasoning ability is known as one of the objectives of mathematics learning at every level of education. At the secondary high school level, mathematics subjects demand students to be able to use their reasoning skills. Measurements of this mathematical reasoning ability are done using instruments that constructed based on mathematical reasoning indicators. One instrument that uses mathematical reasoning indicators in Indonesia is the national examination. The results of the test answers from 2014 to 2016 are then analyzed to find the problems included as the indicators of mathematical reasoning ability. After that, the answers of 2000 students were analyzed using Kruskal Wallis Test to compare whether there is a difference of students’ mathematical reasoning ability in secondary high school by answering math problems correctly from 2014 to 2016.
