Abstract

This study aims to analyze the bibliometric mapping the mathematics' role in everyday life. This study uses a qualitative method by comparing the information obtained from a Google Scholer search. This method is entirely based on the hunt for journal articles developed through bibliometric analysis. Data was collected using Publish or Perish (PoP) and visualized using VOSviewer. In this study, researchers obtained metadata from as many as 995 articles of applied mathematics in everyday life published on April 15, 2022, using a database of 1000 articles from 1926 to 2022. The results and discussion of the bibliometric analysis that has been carried out show that this research topic is still possible. Other researchers for the next period because the data that has been analyzed is still categorized as feasible, and there are still few studies related to bibliometric mapping of the role of mathematics in everyday life. Then suggestions for further research if researchers are interested in choosing a research topic on bibliometric mapping of the role of mathematics in everyday life, namely by connecting various other activities in society and combining it with the progress that developed during the research period so that the data obtained is always up-to-date to evaluate the effectiveness of mathematics in daily life

Abstract

Mathematical communication skills are essential skills that students must have in learning mathematics. The communication process can help students build their understanding of concepts in mathematics and are easy to understand. Mathematical communication is a tool for transmitting mathematical knowledge in building mathematical knowledge in learning activities. Indicators of students' ability to communicate mathematically in learning mathematics are (1) expressing mathematical ideas by speaking, writing, demonstrating, and describing them in visual form, (2) understanding, interpreting, and assessing mathematical ideas presented in written, oral or visual form, (3) use language, notation and mathematical structure to express ideas, draw relationships and build models. This study aims to: (1) describe the mathematical communication skills of grade 7 students in completing mathematical modeling on the One Variable Linear Equation (PLSV) material and (2) identify the components of students' mathematical communication skills on each achievement indicator. This research is a qualitative descriptive study. A qualitative approach is used to understand the context of the subject. Based on the three indicators of students' mathematical communication skills, an average of 17.86% of students' skills can be classified as very low. It shows that most students cannot model solving real problems or everyday life related to mathematical communication.

Abstract

The study's purpose is to describe the cognitive conflicts experienced by students with relational understanding when solving the problem of three-term ratios. The current research is a case study with a qualitative approach using a purposeful sampling technique. The three research objects are representations of the condition that (1) the student was sure of his solution (cognitive conflict was solved) and the solution is correct, (2) the student was confident with his solution (cognitive conflict was solved) but the solution is not correct, and he is not confident with the solution (cognitive conflict was not solved), and the solution was not correct. The results of this study describe students with relational understanding experience cognitive conflicts, that is, being aware of the conflict between the initial concepts they have and the results obtained. Students feel doubtful and worried, as indicated by the awareness that the initial scheme applied to one proportion problem cannot be applied to other comparison questions. Students' cognitive conflicts with relational understanding do not always lead them to get the correct solution to the three-term ratio problems. The reason is that the student believes comparison is wrong (misconception).

Abstract

The data revolution in medical records has increased the automation of medical devices in determining the factors that cause any disease, but it also poses challenges to their analysis. According to WHO, about 6% of the world's population of more than 420 million people live with type 1 or type 2 diabetes and this number has estimated to rise beyond half a billion by 2030, which means that one of the ten adults in the future is suffering from diabetes. With the rapid development of machine learning, machine learning has been applied to many aspects of medical health. In this study, we used Decision Tree C4.5 to predict diabetes mellitus. This research used a diabetic dataset obtained from UCI machine learning repository with 419 instances and 16 attributes. In this dataset, mostly of attributes are numeric types that are continuous. This research results of the improved C4.5 algorithm by applying PCA. Many algorithms have been proposed to overcome misclassification and overfitting on classifications Decision Tree C4.5. Feature reduction is one option that is intended to eliminate irrelevant data and overcome outliers in the data so as to increase classification accuracy. Based on the results of the experiment, the application of PCA in C4.5 resulted in an increase in accuracy of 6.55% were achieved.
