Abstract

The purpose of this study was to determine the effect of students' numerical ability on learning achievement in terms of the student achievement index at STIKOM Tunas Bangsa Pematangsiantar. This type of research is quantitative research. The sample in this study were second semester students from various departments at STIKOM Tunas Bangsa. Many samples used in this study amounted to 80 students. In collecting data used documentation and test instruments. To determine the influence used simple regression analysis. The results of the regression analysis obtained a significance value of <0.05, namely 0.000 <0.05, meaning that there is a significant influence on students' numeracy literacy skills on learning achievement. As for the coefficient of determination, a value of 0.215 is obtained, which means that the effect of the independent variable (numerical ability) on the dependent variable (learning achievement) is 21.5%. linearity test obtained sig. deviation from linearity > 0.05 or 0.517 > 0.05, meaning that the data has a linear pattern with the regression equation Y = 3.061 + 0.008 X. The correlation coefficient of the research data is 0.465, thus the magnitude of the contribution of numeracal ability to learning achievement is 46.5% , while the rest are influenced by other factors not observed in this study.

Abstract

One of the factors for the low mathematical understanding of students is the inappropriate learning method. The selection of the STAD method is believed to be able to improve students' mathematical understanding. This research uses a quantitative approach (pre-experiment). This study aims to determine the difference in students' mathematical understanding before and after using the STAD method. The research population consisted of STIKOM Tunas Bangsa students majoring in Information Systems in the 2023-2024 academic year, with 8 classes, and the sample was drawn from class 23S01. Quantitative data analysis using SPSS 25, namely paired sample t-test. The results showed that the correlation value was 0.714, indicating a strong and significant correlation between initial understanding and final understanding. Based on the mean value of initial understanding (pretest) with a value of 70.83, lower than the mean final understanding (Post-test) after using the STAD method of 79.44. The sig. A value of 0.00 or smaller than 0.05 states that mathematical understanding after using the STAD method is higher than before using the STAD method. Thus, it can be concluded that there is a significant and strong increase in mathematical understanding after using the STAD-type cooperative method in higher education, one of which is for STIKOM Tunas Bangsa students
