Abstract

Mathematical Critical thinking is one of  mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge.  Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the  abilities  of students' mathematics critical thinking.

Abstract

AbstractThis research is based on several inquiries from mathematics educators on the origins of negative numbers and their acceptance in the community. This study used library research, or more precisely, bibliographical studies, as a method. The research examined how the Asian and European communities accept negative numbers. The study's findings indicated that the Asian and European communities accept negative numbers differently. In comparison to the Asian population, the European populace takes a long time to accept negative figures. It resulted in numerous contrasts between the Asian and European Communities, one of which is in terms of religiosity. This study established that religiosity has an effect on the Asian and European communities' acceptance of negative numbers.AbstrakPenelitian ini didasarkan pada beberapa pertanyaan dari pendidik matematika tentang asal-usul bilangan negatif dan penerimaannya di masyarakat.

Abstract

Suppose G(V,E) be a connected simple graph and suppose u,v,x be vertices of graph G. A bijection f : V ∪ E → {1,2,3,...,|V (G)| + |E(G)|} is called super local edge antimagic total labeling if for any adjacent edges uv and vx, w(uv) 6= w(vx), which w(uv) = f(u)+f(uv)+f(v) for every vertex u,v,x in G, and f(u) < f(e) for every vertex u and edge e ∈ E(G). Let γ(G) is the chromatic number of edge coloring of a graph G. By giving G a labeling of f, we denotes the minimum weight of edges needed in G as γleat(G). If every labels for vertices is smaller than its edges, then it is be considered γsleat(G). In this study, we proved the γ sleat of paths and its derivation.

Abstract

Let G = (V, E) be a simple undirected graph. A labeling f : V(G)→{1, …, k} is a local inclusive d-distance vertex irregular labeling of G if every adjacent vertices x, y ∈ V(G) have distinct weights, with the weight w(x),x ∈ V(G) is the sum of every labels of vertices whose distance from x is at most d. The local inclusive d-distance vertex irregularity strength of G, lidis(G), is the least number k for which there exists a local inclusive d-distance vertex irregular labeling of G. In this paper, we prove a conjecture on the local inclusive d-distance vertex irregularity strength for d = 1 for tree and we generalize the result for block graph using the clique number. Furthermore, we present several results for multipartite graphs and we also observe the relationship with chromatic number.

Abstract

Let $G$ be a simple, finite, and undirected graph. An $H$-supermagic labeling is a bijective map $f : V(G) \cup E(G) \to \{1,2,\cdots,|V(G)|+|E(G)|\}$ in which $f(V) = \{1,2,\cdots,|V(G)|\}$ and there exists an integer $m$ such that $w(H') = \sum_{v  \in V(H')} f(v) + \sum_{e \in E(H')} f(e) = m$, for every subgraph $H' \cong H$ in $G$. In this paper, we determine some classes of trees which have $P_h$-supermagic labeling.

Abstract

Let G be a simple, finite, and undirected graph and H be a subgraph of G. The graph G admits an H-covering if every edge in G belongs to a subgraph isomorphic to H. A bijection f : V(G)∪E(G)→[1, n] is a magic total labeling if for every subgraphs H′ isomorphic to H, the sum of labels of all vertices and edges in H′ is constant. If there exists such f, we say G is H-magic. A graph F is said to be a forbidden subgraph of H-magic graphs if F ⊆ G implies G is not an H-magic graph. A set that contains all forbidden subgraph of H-magic is called forbidden family of H-magic graphs, denoted by F(H). In this paper, we consider F(Ph), where Ph is a path of order h. We present some sufficient conditions of a graph being a member of F(Ph). Besides that, we show the uniqueness of a minimal tree which belongs to F(P3) and characterize P3-(super)magic trees.

Abstract

For a simple graph G, a bijection f : V(G) → [1,|V (G)|] is called as a local inclusive distance antimagic (LIDA) labeling of G if w(u) ≠ w(v) for every two adjacent vertices u,v ∈ V(G) with w(u) = ∑x∈N [u] f(x). A graph G is said to be local inclusive distance antimagic (LIDA) graph if it admits a LIDA labeling. The function w induced by f also can be seen as a proper vertex coloring of G. The local inclusive distance antimagic (LIDA) chromatic number of G, denoted by χlida(G), is the minimum number of colors taken over all proper vertex colorings induced by LIDA labelings of G. In this paper, we study a LIDA labeling of simple graph. We provide some basic properties of LIDA labeling for any simple graphs. The LIDA chromatic number of certain multipartite graphs, double stars, subdivision of graphs and join product of graphs with K1 are also investigated. We present an upper bound for graphs obtained from subdivision of super edge-magic total graphs. Furthermore, we present some new open problems.

Abstract

Consider a finite graph G that is simple, undirected, and connected. Let W be an ordered set of vertices with |W| = k. The representation of a vertex v is defined as an ordered k-tuple that consists of the distances from vertex v to each vertex in W. The set W is called a resolving set for G if the k-tuples for any two vertices in G are distinct. The metric dimension of G, denoted by dim(G), is the smallest possible size of such a set W. In this paper, we determine the metric dimension of edge comb product of trees with complete multipartites or petersen graphs.

Abstract

Mathematical spatial Ability is the ability of a person to imagine and represent a space. The lack of students' spatial mathematical abilities and the lack of variability of existing teaching materials to support mathematical learning became the background of this study. This study aims to produce e-modules using traditional Javanese Sundanese culinary ethnomathematics to facilitate students' valid, practical, and effective spatial mathematical abilities. The Research and Development method is used with the ADDIE development model (analyze, design, develop, implement, evaluate). The research was conducted on a limited basis by involving XII class students at one of the high schools in the Tajurhalang, Cibinong areas. The research instruments include expert validation sheets, student response metrics, and mathematical spatial ability tests. The results of this study show that the developed e-modules obtained very valid criteria based on expert validator assessments, were very practical based on student responses, and the results were valid. It is effective because students' spatial mathematical ability test results are higher than the school-designated Minimum Completeness Criteria (KKM), so e-modules are suitable for use in mathematical learning to facilitate students' spatial mathematical ability.
