of Students' Mathematical Comprehension Ability on Two Variable Linear Equation System (SPLDV) Materials in Class X Students of SMAN 1 MONTASIK

Abstract

Understanding is a translation of the term understanding which is defined as the absorption
of the meaning of a material being studied. This can also be seen in the results of the 2015
PISA (Program for International Student Assessment) test, that the mathematical ability of
Indonesian students is at a low level, even 42.3% of students have not yet reached level 1 of
6 proficiency levels for mathematics and science and make Indonesia a nation. is in position
69 of the 76 participating countries. This research is an exploratory qualitative research that
aims to determine students' mathematical understanding ability in solving math problems
based on students' mathematical abilities. The research method used is descriptive. The
subjects in this study were 6 students and class X students who had different mathematical
abilities, namely 2 students with high abilities, 2 people with moderate abilities, 2 people
with low abilities who were taken at Senior High School 1 MONTASIK school. This
research was conducted to determine the tendency of mathematical understanding ability
according to students' ability to solve story problems about a system of linear equations of
two variables. The results of data analysis show that (1) Students who have a high ability to
understand mathematical abilities have been able to solve problems properly and correctly,
although there are still some who cannot. 2) Students who have moderate ability to
mathematical understanding abilities are able to make examples, make what is known and
what is asked, have not been able to run or operate story problems and are able to make
conclusions. (3) Students who have low ability to understand mathematical abilities have
been able to make examples, but have not made what is known and asked, run or operate
story problems and make conclusions.
