Abstract

This study aims to compare the mathematical problem solving
abilities of students who are taught using the problemc based learning
model and the mathematical problem solving abilities of students who
are taught using conventional learning models in class VII students of
SMP Negeri 18 Satarmese in the 2022/2023 academic year.Pretestposttest control group design is used in the quasi-experimental design
of the research. There were a total of 58 students in class VII at SMP
Negeri 18 Satarmese who participated in this study. Sampling in this
used non-probability sampling or a sampling technique that did not
provide equal opportunities or opportunities for each elemnt or
member of the population to be selected as a sample, so the
researchers made class VII A as the experimental class and class VII
B as the control totaling 29 participants. A description-based
mathematical problem solving ability test was used to gather the
information. Prerequisite tests, such as homogeneity and normality
tests, were carried out prior to the analysis of the data. The data from
both groupd come from a population that is normally distributed and
has a homogeneous variance, as demonstrated by the calculations for
the normality and homogeneity tests. Then a hypothesis test was

carried out to see the studentd’ mathematical problem solving
abilities. The N-gain score data were the ones that were analyzed
using the independent t test statistical method.Based on the data
analysis result obtained that the calculation result = 8,03 and = 1,67
at the significant level and degrees of freedom. Because price = 8,03
> price = 1,67, it is accepted and rejected. Therefore, there are
differences in students mathematical problem solving abilities taught
using the Problem Based Learning model with students mathematical
problem solving abilities taught using conventional models. Based on
the research results, recommendations for further research are to
carry out similar research with other learning models and other
classes.
