Improving Understanding of Mathematical Concepts in Operations Counting Multiplication 6-10 With the Jarimatics Method

Abstract

This study uses a quantitative approach through correlation techniques and survey methods. The population of this study was all fourth grade students of SD Negeri Gudang, Tigaraksa District, Tangerang Regency with a sample of 33 students obtained through random sampling and inferential analysis techniques. The data analyzed in this study is descriptive analysis, which describes the characteristics of the data on each variable consisting of the lowest, highest, mean, median, mode and standard deviation, while inferential analysis includes regression analysis, simple analysis and correlation coefficient. From the analysis, it was found that the portfolio learning model had a significant effect on student learning outcomes in Civics subjects with the subject matter of Indonesian Cultural Diversity for class IV SD Negeri Gudang. This is based on the results of the calculation of the t- test analysis, where there is a difference in the value of the value of tCount with tTable. Where tCount > tTable value or 0,525 > 0,344. With the calculated results, it is known that the coefficient of determination (R Square) is 0.276. R Square value of 0.276. The magnitude of the correlation coefficient is 0.276 or equal to 27.6%. This figure means that Variable X has an effect on Variable Y by 27.6%.
