Abstract

Mathematics learning that uses the circle concept using contextual concepts can make it easier for students to understand mathematical concepts and also broaden students' insight. This research aims to explore the shapes and patterns of Karo musical instruments, namely the gung and Penganak, which will then be used as material for developing learning resources based on the cultural diversity that exists in Tanah Karo. The method used in this research is exploratory with an ethnographic approach. The instrument used in this research is a human instrument, and the data collection techniques used by researchers are observation and documentation. From this research it was found that gung and penganak are flat, circular shapes which can be related to mathematics learning.

Abstract

The Cumulative Grade Point Average (GPA) is used in higher education to measure how well students perform in their studies. Mathematics Education students have varying GPAs each semester due to various factors. The aim of this study is to determine the type of discriminant function, or discriminant model, and identify the components that significantly influence the GPA of Mathematics Education students at HKBP Nommensen University. Another goal is to assess the accuracy of the discriminant function classification. This study involved 50 active students from the Mathematics class of 2020, 2021, and 2022. The sample was taken using a simple random sampling technique, and the research type used was quantitative, as the results are in numerical form and will be analyzed quantitatively using discriminant analysis. The research method employed is also quantitative. Based on the results, a discriminant model was obtained that describes the factors influencing the GPA of Mathematics Education students, with the equation: Y= 0.119 + 6.138X₄ + 8.120X₆ -13.910X₉. The variables that significantly affect GPA are learning motivation, mental health, and campus environment. This discriminant model can classify students with 100% accuracy, allowing it to be used to determine whether a student has a GPA below 3.75 or above/equal to 3.75.

Abstract

This study aimed to determine the effectiveness of the contextual teaching and learning model on students' problem-solving skills and mathematical reasoning abilities in linear equations with one variable. Furthermore, this study sought to investigate the level of effectiveness of the contextual teaching and learning model in enhancing students' problem-solving skills and mathematical reasoning abilities. The research employed a quasi-experimental design with the entire population of grade VIII students serving as the population. Cluster random sampling was used to select the sample. The hypothesis was tested using the F-test. The results showed that (1) the contextual teaching and learning model was effective in improving students' problem-solving skills; (2) the effectiveness of the contextual teaching and learning model in enhancing students' problem-solving skills was categorized as high; (3) the contextual teaching and learning model was effective in improving students' mathematical reasoning abilities; and (4) the effectiveness of the contextual teaching and learning model in enhancing students' mathematical reasoning abilities was categorized as moderate.
