The Students' Ability to Solve Realistic Mathematical Problems through Polya Type Problem Solving Learning Model

This study was done to analyze the effect of Polyatype problem solving
learning oriented toward realistic mathematics on the ability to solve
mathematical word problems. This study belongs to an experimental research
with the Posttest Only Control Group Design. The population used in this
study was the students of grade 4 at Gugus VIII SukawatiGianyarelementary
schools with the total number of 138. The sample was selected through
random sampling. The result of selection by lottery assigned Grade 4
students of SDN 4 SingapaduKaler to the control class and Grade 4 students
of SDN 1 SingapaduKaler to the experiment class. The data were collected
through an essay test that had been validated. The data that had been
collected were analyzed through a difference test (t-test). Based on the result
of data analysis it can be concluded that the use of Polya type problem
solving teaching model oriented toward realistic mathematics gave a positive
effect to the ability to solve word problems among the Grade 4 students in
Gugus VIII Sukawati Gianyar.
