Menentukan Jarak Pada Ruang Dimensi Tiga Dengan Analisis Vektor
Abstract
This article is a study on the ways of vector concepts to determine the distance in threedimensional
space.
Typically,
mathematics
learning
has
introduced
three-dimensional
to
students
at
the
middle
school.
These
three-dimensional
learning
during
ordinary
was
implemented
by
based
on
spatial
ability,
both
conventional
and
computer-assisted
learning.
Student
spatial
intelligence
is
different
clearly. Based on the result of several studies in the literature, especially for female
students has shown that they were difficulties in the mathematical spatial problem so that there
was an imbalance of learning achievement, and vector concepts can be used to help. The purpose
of this article is knowing how to determine of geometrical measure on the solid using vector
concepts. Vector concepts in this study as one of all of counting alternative by students high school
who have spatial difficulties. Vector concepts that be used like orthogonal projection and vector in
the direction normal to the plane. Using the vector concepts because of solid like cube can be
drawn on three-dimensional of coordinate. On the other hand, the spatial relation like points,
lines, and planes was studied in vector analysis. Using of vector concepts, student’s three dimensional learning would not involve much of spatial ability, but student’s ability in
mathematical count would have been more.
