Abstract

The reduced interest of students in learning mathematics and consider
mathematics to be a difficult subject to become a serious problem in Indonesia,
especially in one of the provinces in Indonesia,  Lampung. The purpose
of this study was to determine the effectiveness of the demonstration method
assisted by Multiplication Board props to the understanding of the third grade
mathematical concept of Bandar Lampung.

This type of research is quantitative research with the type of Quasy
Experimental Design. The design used is the Pretest-Postest Control Group
Design. Data collection techniques in this study consisted of interviews, tests
and documentation. The population of this study was class III Bandar Lampung
students. The sample in this study is class III A as the experimental class
with the demonstration method, class III B as the control class using
conventional methods. Data analysis techniques used the normality test with
Lilifors test and homogeneity test with Bartlett test. Followed by testing the
hypothesis that is using independent tests.

Based on the results of the analysis and discussion of the research
data obtained the results of hypothesis testing manually with t count = 4.265
and t (0.025; 38) = 1.960, so that tcount> t (0.025; 38) then HO is
rejected. Based on these results, there is an understanding of the concept of
mathematical multiplication between students who are taught using the
demonstration method compared to using conventional methods.
