Abstract

The purpose of this study is to determine the relationship and influence of understanding mathematical concepts with mathematical reasoning in learning matrix on grade XI of senior high school. In this study the survey method was conducted using random sampling. The scores were obtained from the 54 students' understanding and mathematical reasoning tests. Based on SPSS calculations 20. Correlation coefficient between the understanding of mathematical concepts with mathematical reasoning is 0.695, meaning a strong relationship. The significance value is 0,000 <0,005 which means that it is significant. The regression equation is  = -0,989 + 9,71, if there is no concept understanding then mathematical reasoning is negative. The regression coefficient X value of 9.71 states that each addition of one value to the understanding of mathematical concepts will increase mathematical reasoning by 9.71. From the data and analysis above, it is shown that there is a significant relationship between understanding concepts and students' mathematical reasoning on the matrix material, indicated by the correlation coefficient of 0.695, which means a strong relationship, sig. 0,000 <0.005 that means significant.

Abstract

One of the mathematical abilities that students must have is the ability to count. The prerequisite in learning mathematics is learning to count, both of which are interconnected in supporting mathematical abilities. This study aims to improve students' numeracy skills and efforts to grow students' interest in mathematics. One of the solutions to the problem of mathematical arithmetic abilities is the Trachternberg method. If the rules of the Trachternberg mathematical method have been mastered then the calculations can be simple and fast in solving them. Classroom action research was used in this study, the approach was a quantitative and qualitative approach divided into 3 learning cycles. The research was conducted in November 2019 at SMPIT Ruhama Depok with a sample of 20 students. The results of the application of the Trachternberg method were an increase in students' numeracy skills and interest in mathematics; this was indicated by the percentage of interest of 80.09%, the percentage of completeness of numeracy skills of 75% with an average value of 77.
