Abstract

A part of the triangular fuzzy numbers, is what we call pentagonal fuzzy numbers. Plentyof alternatives for fuzzy pentagonal numbers are suggested by some writers. Particularlyfor scalar summation, subtraction, and multiplication, there is no enormous diversity.However, for multiplication, division, and inverse as well, there are so many algebraicoptions proposed by various scholars. Some writers defined the form of inverse for pentagonal fuzzy numbers in parametric. But it does not always result in identity. Sucha thing will also have implications in the process of how to invers the pentagonal fuzzynumbers matric. This paper proposes an alternative method to decide the inverse ofpentagonal fuzzy numbers, in the form of parametric. The first thing to do is toconstruct two midpoint for any pentagonal fuzzy. The midpoint are used to constructthe multiplication, division and inverse. Algebraic to any pentagonal fuzzy number inany single inverse such that it produces an identity inverse, likewise for a pentagonal fuzzy number matrix it produces an identity matrix inverse. Keywords: Algebraic Alternative Fuzzy Number; Inverse Of Penthagonal Fuzzy Number Matric

Abstract

Hexagonal fuzzy numbers are a development of trapezoidal fuzzy numbers. Just like algebra for trapezoidal fuzzy numbers. There are not many algebraic differences given by various authors for the many operations of addition, subtraction, and scalar multiplication.  However, for multiplication, division, and inverse operations, there are many algebraic alternatives offered by various authors in parametric and ordinary forms. But the problems that arise do not always have an inverse for any hexagonal fuzzy number  . In this paper, by changing hexagonal fuzzy numbers into another form  and defining two midpoints  and  for any hexagonal fuzzy number . Thus, for the algebraic forms of multiplication, division, and inverse there is one that is produced  using the elementary row method. At the end, an example of determining the inverse of a hexagonal fuzzy number matrix that has order .  Keywords: Algebra arithmetic, hexagonal fuzzy number, inverse matrix

Abstract

This research aims to describe how students’ understanding of adding and subtracting whole numbers is formed. This research is a qualitative descriptive study with teaching modules as the main data source. After surveying didactic situation theory in mathematics through various sources, the paradigm in this theory is then used as a basis for describing learning activities contained in the teaching module. Learning activities in the teaching module are classified based on the theory of mathematical didactic situations. The result shows that in these learning activities, the didactical situation was not developed sequentially. Apart from that, the action situation that is constructed does not show the existence of a dialectical situation between individual students and the milieu. Knowledge construction tends to come from teacher explanations, not from the process of solving problems that involve students' mental activity. This condition can potentially cause knowledge not to be constructed properly, making it possible for students not to be able to use it when facing new mathematical problems and allowing learning obstacles to occur. Keywords: didactical situations, teaching module

Abstract

The ability to understand concepts is a crucial skill for comprehending, providing examples, and applying concepts, thereby fostering meaningful learning. However, students’ mathematical conceptual understanding is still relatively low. To achieve meaningful learning, improvements are necessary through a specific approach, namely the Indonesian Realistic Mathematics Education (PMRI). In achieving learning objectives, lessons need to be well-designed, one of which is through the Hypothetical Learning Trajectory (HLT). This study designs an HLT for logarithm concepts using the PMRI approach to improve students’ mathematical conceptual understanding at a high school (SMA/MA) in Sungai Penuh City, Jambi Province, employing a design research method. The research instruments include Student Activity Sheets, questionnaires, and conceptual understanding tests. The data collection techniques consist of interviews, observations, tests, and documentation. The research results indicate that the designed HLT is valid, and students can discover the concept of logarithms. After learning with the PMRI approach, students’ responses to PMRI reached 75.5%, while their mathematical conceptual understanding after the PMRI approach was categorized as high for 46.7% of students, moderate for 36.7%, and low for 16.7%.

Abstract

This study aims to determine the effect of the Ethnomathematics-Based Problem-Based Learning (PBL) model on the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru. The research employs a quasi-experimental design with a pretest-posttest control group. The sample consists of two classes selected through random sampling: an experimental class taught using the ethnomathematics-based PBL model and a control class taught using conventional learning methods. After conducting the normality test, the post-test significance value for the control class was found to be 0.004, which is smaller than the significance level of 0.05 (0.004 < 0.05). Thus, the data are not normally distributed. Since one of the datasets is not normally distributed, a non-parametric Mann-Whitney U test was performed. The test results show an Asymp. Sig. (2-tailed) value of 0.000, which is smaller than the significance level of 0.05 (0.000 < 0.05). Therefore, H1 is accepted, and H0 is rejected. This indicates a difference in the average numeracy skills between the experimental class and the control class. In other words, the average numeracy skills of students using the Ethnomathematics-Based Problem-Based Learning (PBL) model are better than those of students using the conventional learning model. Hence, the ethnomathematics-based Problem-Based Learning (PBL) model positively impacts the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru.

Abstract

The purpose of this study was to describe students' mathematical communication skills in solving problems involving integer operations. Mathematical communication is the effective delivery of ideas, understanding, and mathematical concepts between individuals, covering various aspects, including the use of symbols, language, and graphics to explain mathematical concepts and solutions. This research method uses a qualitative method. The results of the study showed that two highly capable subjects were able to complete well according to what was instructed according to the mathematical communication indicators, namely written text, drawing, and mathematical expression. Based on interviews, both subjects were able to explain according to what was done (each student's answer). While low-ability subjects completed well according to what was instructed according to the mathematical communication indicators, namely written text and mathematical expression, both subjects were unable to meet the drawing indicator. Based on interviews, both subjects were able to explain according to what was done (each student's answer) on two mathematical communication indicators, namely written text and mathematical expression, but were unable to explain on the drawing indicator. Keywords: integers, mathematical communication, solving problems

Abstract

This study aims to evaluate the effectiveness of visual media in enhancing students' understanding of abstract concepts in mathematics learning. The research method used was experimental. The study sample consisted of 35 eighth-grade students from MTs Al Amiriyyah Banyuwangi, selected using random sampling techniques. Visual media were utilized as the independent variable, while students' understanding was the dependent variable. Data analysis results indicate that visual media have a significant impact on students' understanding, with a correlation value of r = 0.569, signifying a strong positive relationship. The coefficient of determination of 32.4% suggests that visual media contribute substantially to improving students' comprehension. Simple linear regression analysis revealed that visual media significantly affects students' understanding (significance value = 0.000 < 0.05). This study concludes that the effective use of visual media can enhance students' understanding of mathematics learning. Keywords: visual media, student understanding
