THEDIFFERENCE OF STUDENTS’ MATHEMATICAL REPRESENTATION ABILITY BY USING PROBLEMBASED LEARNING AND INQUIRY BASED LEARNING ON THE TOPIC OF STATISTICS IN GRADE VIII SMP NEGERI 1TANJUNG MORAWA ACADEMIC YEAR 20 1 6 /2 01 7

The type of this research is quasi – experiment.The aim of this research was to
determine whether student’s Mathematical Representation Ability taught by using
Problem Based Learning is higher than Inquiry Based Learning for Grade VIII in
SMP Negeri 1 Tanjung Morawa. The population is all students of grade VIII in SMP
Negeri 1 Tanjung Morawa A.Y. 2016/2017. Sampling Techniques that is used in this
research is Purposeful sampling. There are two samples in this research namely,
Experimental class A isVIII-1 taught by Problem Based Learning and Experimental
class B is VIII-2 taught by Inquiry Based Learning. This research using posttest only
group control, Technique of analzying data is consisted of normality, homogeneity,
and hypothesis test. Based on normality and homogeneity test, the data was taken
from normal distribution and homogeneous population. The result of the research
shows that the mean score are 83.08 in experiment class A and 78.58 in experiment
class B and results of hypothesis test of data from both experimental class in post test
was found that . It indicates that H₀ is rejected.
So, we can conclude that the students’ mathematical representation ability in the
classroom taught using Problem-Based Learning model is higher than in the class
taught using Inquiry Based Learning model.
