Abstract

This study aims to determine the effect of reading interest and study habits on mathematics learning outcomes. The results showed that the variables of reading interest and study habits simultaneously (simultaneously) had an influence on mathematics learning outcomes which were expressed by the following regression equation model: Y = 49,014 + 0,479X1 – 0,212X2. From the results of the analysis, it can be concluded that the variables of reading interest and study habits together have a significant influence on mathematics learning outcomes. The two independent variables contributed to the learning outcomes of mathematics by 17%. While partially, reading interest and learning habits each have a significant influence on mathematics learning outcomes.

Abstract

This study aims to determine the classification of student graduation timeliness by using the Decision Tree and Naïve Bayes methods. This study uses a quantitative method, where the approach used is the classification of various attributes that affect the timeliness of student graduation. The independent variables in the classification are mostly called attributes; In this study, the attributes of school of origin, gender, area of origin, profession of parents, study program and Grade Point Average (GPA) were used. While the dependent variable or in the classification is usually called a label, in this study the label used as a decision attribute is the timeliness of student graduation. In this study, two methods were used, namely using the nave Bayes method and a decision tree (decision tree) to determine the classification of the timeliness of student graduation and to determine the level of classification accuracy. Based on the results of the analysis, it can be concluded that the classification using the nave Bayes method obtained 36 predicted data according to the actual data and 7 different predicted data from the actual data. Meanwhile, in the 42 decision tree method, the predicted data is in accordance with the actual data and there is only 1 predicted data that is different from the actual data. Decision Tree method has a lower classification error rate than the Naïve Bayes method. The level of accuracy of prediction results using the Decision Tree method is higher than the Naïve Bayes method.

Abstract

The research aims to determine the direct and indirect influence of mathematical anxiety, logical-mathematical intelligence, and critical thinking abilities on the learning outcomes acquired by students. Many things affect the teaching and learning process, both from outside the student's environment and from within the student himself. The unpreparedness of external and internal factors will create obstacles in the learning process of the student, which will then affect their learning outcomes. These include mathematical anxiety, mathematical logical intelligence, and critical thinking abilities. Students who experience mathematical anxiety tend to avoid conditions where they feel threatened and stressed. Of course, these people will think or assume negative thoughts about themselves. Mathematical logical intelligence plays a significant role for students in understanding abstract mathematics lessons. The challenge in the world of education is that it requires students to think at higher levels (HOTs). Critical thinking is a logical and natural thinking process that already exists in a person when facing changes in all sectors of life. The method used in this research is structural equation modeling (SEM), which will look at direct and indirect effects. The research results show that 1) mathematics anxiety has a significant positive influence on critical thinking abilities; 2) logical-mathematical intelligence has a significant positive influence on critical thinking abilities; 3) critical thinking skills have a significant positive influence on student learning outcomes; 4) mathematics anxiety has a significant positive influence on student learning outcomes; 5) logical-mathematical intelligence has a significant positive influence on student learning outcomes; 6) mathematics anxiety has a significant positive influence on student learning outcomes through critical thinking skills; and 7) logical-mathematical intelligence has an insignificant positive influence on student learning outcomes through critical thinking skills.

Abstract

In the 21st century, the learning process continues to develop and undergo a paradigm shift. One of the characteristics of the 21st century is the presence of aspects of information, computing, automation, and communication that influence the learning paradigm. In learning statistics, it is not only cognitive skills that support student learning success but also non-cognitive skills. This study aims to determine the effect of student computer ability anxiety and self-efficacy beliefs on student attitudes toward statistical courses. The sample of this study was 203 students of the Mathematics Study Program of Pamulang University who were selected using a simple random sampling technique. Data collection techniques in this study used instruments with a Likert scale. The effect on the research variables was analyzed using structural equation modeling to determine the effect. From the results of the analysis, it is obtained that there is a direct influence of computer ability anxiety on self-efficacy beliefs in learning statistics, there is a direct influence of computer ability anxiety on attitudes towards statistics courses, there is a direct influence of self-efficacy beliefs in learning statistics on attitudes towards statistics courses, and there is an influence of computer ability anxiety in learning statistics on attitudes towards statistics courses through self-efficacy beliefs.

Abstract

HDI is a benchmark for a country in achieving human development in the country. Indonesia is a developing country with a relatively increasing HDI value every year. This shows that the efforts made by Indonesia are going well. However, Indonesia experienced a decrease in HDI value in 2019 towards 2020, due to restrictions on activities caused by the Covid-19 pandemic. In addition, the HDI value in each province in Indonesia is uneven, even from the publication data of the Central Statistics Agency (BPS) shows a significant difference in HDI value between provinces in Indonesia. So that evaluation and improvement are needed to be able to equalize and stabilize HDI in Indonesia. HDI value can be influenced by several factors including economy, education, and health. This study aims to determine the direct effect of economic variables on HDI, the direct effect of education variables on HDI, the direct effect of health variables on HDI, the indirect effect of education variables on HDI through economic variables and health variables. The data used in this study are data on the Human Development Index of economic, education and health variables along with the indicators that measure them, from 34 provinces in Indonesia in 2022. This study applies SEM-PLS to determine the factors that influence the Human Development Index (HDI). The results of this study indicate that economic variables and education variables have a direct influence on the Human Development Index (HDI), while health variables have no direct influence on the Human Development Index (HDI). Then the education variable through the economic variable has an indirect effect on the Human Development Index (HDI), and the education variable through the health variable has no indirect effect on the Human Development Index (HDI).
