Kesalahan Mahasiswa PGSD UTM dalam Menyelesaikan Sistem Persamaan Linier Tiga Variabel Berbentuk Soal Cerita
Abstract: This paper describes
the errors of the research subjects in solving Linear Equation System (LES)
with three variables in form of narration. The errors that the students made in
solving this mathematical problem hopefully can be used as one of the
considerations in deciding the learning method or improving the learning. This
paper is an exploratory descriptive paper. The research subjects are PGSD
department students of University Trunojoyo Madura even semester of academic
year 2011-2012 as many as 52 students.
The data analysis is done in three stages, which are: (a) data reduction, (b)
data presentation, and (c) inference. The research results indicate some errors
done by the students are as follow: (a) errors in creating mathematical models;
(b) errors in inscribing determinant method formulas; (c) errors in inputting
data into the determinant method formulas; (d) errors in calculating using
determinant method; and (e) errors in the actual problem solving stage.
