Abstract

This research aims to determine whether there is an influence of the reciprocal teaching learning model assisted by Student Worksheets (LKPD) on the mathematical communication skills of students at Senior High School 7 Mataram for the 2023/2024 academic year. This research is included in quantitative research with a quasi-experimental design research type with a posttest-only control design. The population in this study were all class X students at Senior High School 7 Mataram for the 2023/2024 academic year with samples from classes X.K and the instruments in this research are observation sheets and tests of mathematical communication skills as well as data analysis techniques using valid tests, namely the normality test, homogeneity test and hypothesis test. The results of this research show that there is a difference in the average value of the mathematical communication skills of students who use the reciprocal teaching learning model assisted by LKPD and students who use the conventional learning model. So this shows that there is an influence of the reciprocal teaching learning model assisted by Student Worksheets (LKPD) on the mathematical communication skills of students at Senior High School 7 Mataram in the 2023/2024 academic year

Abstract

Reasoning ability is a high-level thinking ability in learning mathematics. Mathematical reasoning and mathematics learning are two things that are interrelated and cannot be separated because mathematical material is understood through reasoning, and reasoning can be trained through studying mathematics. To achieve mathematical reasoning abilities in learning, students need adequate behavior, one of which is learning independence. The aim of this research is to analyze mathematical reasoning abilities based on students' independent learning at SMPN 1 Praya Timur on straight line equations. The method used in this research is qualitative research with descriptive methods. The samples in this study were taken randomly based on the class in the population. The class that the researcher took as a sample in this study was class VIII C at SMPN 1 Praya Timur for the 2023–2024 academic year. The results of this study show that subjects with low reasoning abilities are also categorized as having low learning independence. The learning ability of students who are categorized as moderate turns out to be moderate. So, it can be concluded that the relationship between learning independence and reasoning ability is based on high student learning independence, so their reasoning ability is also high. Based on the results of this research, it is hoped that teachers can develop teaching and practice problem-solving questions to improve students' reasoning abilities

Abstract

This research was conducted to determine the effect of cooperative learning model type think talk write (TTW) on mathematical communication skills in students of SMPN 13 Mataram class VIII on statistics material. Quantitative approach with quasi experimental method was used in this research. The population in this study was all VIII grade students of SMPN 13 Mataram consisting of five classes, with a sample consisting of two classes, namely class VIII E as an experimental class using the cooperative learning model of think talk write (TTW) type and class VIII A as a control class using direct learning model. Data collection techniques used observation sheets, documentation, and tests. The results of data analysis showed that there was an average difference between the experimental and control classes. The t-test results obtained a t-count value of 2,939, and the t-table value obtained a value of 1,669, indicating that the t-count value was greater than the t-table. Thus, the Think Talk Write (TTW) cooperative learning model has a positive effect on students' mathematical communication skills. This research suggests the application of TTW model as an effective learning strategy to improve students' mathematical communication skills at junior high school level

Abstract

Metric dimension is an important concept in graph theory that is widely used in various fields, including navigation, network localization, and network design. The concept of metric dimension is the concept of determining the least marker vertex so that each vertex in the graph is distinguished from each other. The purpose of this research is to determine the metric dimension of the pinwheel subdivision graph ????1+????????3. The type of research used is pure research. By using graph structure and vertex distance analysis, this paper shows the value of the metric dimension of the subdivision graph ????(????,????), specifically on the pinwheel graph ????=????1+????????3 for 2≤????≤4. The results show that the metric dimension of the pinwheel subdivision graph ????1+????????3 is one less than the metric dimension of the pinwheel graph before subdivision, ????????????(????(????,????))=????????????(????)−1.

Abstract

This project highlights the significance of parabolas in technology, science, and architecture while examining their various everyday uses. Because they can concentrate sound waves at a particular location, parabolic shapes are essential in the construction of satellite dishes, automobile headlights, and flashlights. This project illustrates how mathematics and practical problem-solving structural stability and visual appeal. This project illustrates how mathematics and practical problem solving interact by jamming the uses of parabolas, showing how a straightforward geometric shape can transform technology and enhance everyday life.
