PENGARUH PENERAPAN STRATEGI PEMECAHAN MASALAH DALAM PEMBELAJARAN MATEMATIKA TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA KELAS VIII SMP AL-AZHAR SYIFA BUDI PEKANBARU

Abstract

Abstract: This research is a pre-experimental research with the static group
comparison study design, that aims to determine whether the application of problemsolving
strategy in mathematics learning positively affect on mathematical problem
solving ability of students of class VIII SMP Al-Azhar Syifa Budi Pekanbaru school year
2015/2016. This research involved experimental and control classes that consists of 24
students and 20 students. The test score of students’s mathematical problem solving
ability is the data that used to test hypothesis of the research. Based on the test score,
obtained the average value of mathematical problem solving ability of students in
experimental class was 3,40 and the average value of mathematical problem solving
ability of students in control class was 2,16. From the Mann-Withney test, obtained the
significance is 0,001 (less than ߙ = 0,05), it is mean that ܪ଴ has rejected and ܪଵ has
accepted. The average value of test mathematical problem solving ability of students in
experimental class is higher than the average value of test mathematical problem
solving ability of students in control class, it can be conclude that the application of
problem-solving strategy in mathematics learning positively affects the mathematical
problem solving ability of students of class VIII SMP Al-Azhar Syifa Budi Pekanbaru
school year 2015/2016.
