PENERAPAN PENDEKATAN SAINTIFIK BERBASIS MASALAH KONTEKSTUAL UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIK

Abstract

This study aims to determine the differences in increasing the ability of
mathematical representation and the acquisition of mathematical problem solving
abilities between students who get learning with a scientific approach based on
contextual problems with students who get expository learning. This type of
research is quasi-experimental. The sample was 79 VII grade students who came
from two classes in one State Junior High School in Lembang Regency. First class
gets learning with a scientific approach based on contextual problems and the
second class gets Expository learning. Both classes posttest mathematical problem
solving abilities. The results showed that (1) there was a difference in the overall
acquisition of mathematical problem solving abilities between students who
studied with a scientific approach based on contextual problems and students who
received expository learning; (2) there are differences in the acquisition of
mathematical problem solving abilities based on students' initial mathematical
abilities (high, medium, low) (3) there is an influence of interaction between the
learning model and students' initial mathematical abilities on improving students'
mathematical problem solving abilities.
