Abstract

Absrtact
Mathematics is one of the compulsory subjects taught at all levels of education. a model is needed
to support students' needs to improve students' understanding of concepts. The CORE learning
model with the Student facilitator and explaining strategy is very good in improving students'
understanding of mathematical concepts. The purpose of this study was to determine the
effectiveness of the CORE model with a student facilitator and explaining strategy on students'
understanding of mathematical concepts. This study uses a quantitative method with a quasiexperimental approach and a non-equivalent control group design. the author conducted a test of
validity, normality, homogeneity and reliability of the test to determine the correctness and
suitability of the instrument used. From the calculation results, the results of the test have a valid
value and have a normal distribution. For the homogeneity and reliability test, all items were
homogeneous. The calculation using the Crombach alpha reliability test was obtained for all items
more than 0.05, so all items on the test were appropriate or reliable. It is known that the results of
the t-test analysis in the experimental class have an average value (mean) of 63.7 post-test and
pre-test of 47.5, the increase in the average result is known to be 16.2 for all test results. In
addition, from the results of the percentage of the effectiveness of the model category, the result is
a value of 63.75. So, from these results the category of effectiveness of the learning model is
included in the category of quite effective.


Keywords: Effectiveness, CORE Model and Student Facilitator and Explaining Strategy, Understanding Mathematical Concepts
