EFFECTS OF LEARNING MEDIA TRAY BOARDS (DIVE AND TIMES) ON STUDENTS' MATHEMATICAL UNDERSTANDING OF OPERATIONAL MATERIALS CALCULATE THE DIVISION AND MULTIPLE OF WHOLE NUMBERS

(Experimental Research on Class II Students of Paniis Elementary School, Tanjungkerta District Sumedang Regency Academic Year 2021/2022)

Abstract

This research is motivated by the low mathematical understanding of
students on the material of division and multiplication. This study is
intended to determine the effect of BAKI board learning media on students
mathematical understanding of the material for arithmetical operations
division and multiplication of whole numbers. The method used in this
research is an experiment with a research design One-Group Pretest-Posttest
Design. The data collection technique used was a written test with 5 PG
questions and 3 essay questions. The subjects in this study were second
grade students of SDN Paniis which consisted of 10 people.
Based on the results of the calculation of the pretest and posttest data
through the t-test of 10 students, the average value was 18.7, standard
deviation was 15.15, = 3.90 and = 2.2622. Thus it shows that -
= -2.2622 = 3.90 = 2.2622 so that it is rejected
and accepted. Thus, it can be concluded that there is an influence of
BAKI board learning media (division and multiplication) on the
mathematical understanding of arithmetic operations, division and
multiplication of whole numbers in grade II students of SDN Paniis in the
2021/2022 academic year
