PENGARUH PENDEKATAN PROBLEM SOLVING TERHADAP KEMAMPUAN MENYELESAIKAN SOAL CERITA MATERI TEOREMA PHYTAGORAS

This study aims to find out that the use of problems solving approach has a positive effect on
students' abilities in solving story problems on the Pythagorean theorem class VIII.5 UPTD SMP Negeri
18 Barru. This type of research is quasi-experimental without a control class conducted in one group.
The variables studied in this study were students' ability to solve word problems on the Pythagorean
theorem class VIII.5 UPTD SMP Negeri 18 Barru as the dependent variable and learning using the
problems solving method as the independent variable.
The population of this study were all students of class VIII UPTD SMP Negeri 18 Barru for the
academic year 2022/2023 which consisted of 5 (five) classes. Sampling was carried out by cluster
random sampling, from 5 classes one class was taken randomly namely class VIII.5 as the experimental
class. The instruments used in this study were tests of the ability to solve the Pythagorean theorem
word problems and validated student activity observation sheets. Based on the descriptive statistical
analysis, the average score of students' ability to solve the Pythagorean theorem story problems before
learning using the problem solving learning method was 63,37 and the average score of students' ability
to solve the Pythagorean theorem story problems after learning using the problem solving method was
80,40. Based on inferential statistical analysis using the one sample t-test, a significant value was
obtained, p = 0,004   = 0, this means that H0 is rejected H1 is accepted. So it can be concluded that
there is a positive effect of the problem solving learning method on the mathematics learning outcomes
of class VIII.5 UPTD SMP Negeri 18 Barru
