This study aims to describe the ability of mathematical representation in solving algebraic problems in terms of the ability level of students at SMPN 4 Tanjung, the Academic Year 2021/2022. The type of research used is descriptive qualitative. The sample used was 27 students with the sampling technique used was purposive random sampling. Data collection techniques were carried out through tests and interviews. Based on the results of student test analysis, it was found that (1) the number of subjects in the high category was 6 students, indicating that the visual, symbolic, and verbal indicators were able to solve problems correctly and completely (2) the number of subjects in the medium category was 9 students. , shows that the visual, symbolic, and verbal indicators can state the problem but are incomplete (3) Furthermore, the number of subjects in the low category is 12 students, indicating that students have not been able to achieve the indicators of symbolic and verbal mathematical representation ability. The results of the research on students' mathematical representation abilities are 44.65%, the percentage value obtained from students' mathematical representation abilities on visual indicators is 18.31% in the high category, students' mathematical representation abilities on symbolic indicators are 15.43% in the medium category, then the ability students' mathematical representation of verbal indicators obtained 10.90% in the low category. This research on the ability of mathematical representation uses 3 indicators, namely visual or image representation, symbolic or expression, and verbal or written text words for further development by looking at other representational abilities.

Abstract

Elementary school teachers in Cluster II Gerung District are still very rare in using visual aids in teaching mathematical concepts. As a result, students have difficulty understanding abstract mathematical material, while elementary school children are still at the concrete thinking stage. Therefore, this activity aims to train and assist elementary school teachers in Cluster II Gerung District in implementing Kopermatik teaching aids (Mathematics Game Boxes) for classroom learning. The training method includes discussions and demonstrations in making and using Kopermatik teaching aids as well as simulations in utilizing the Kopermatik teaching aids. This service activity was carried out at an elementary school in Gerung District, with 18 elementary school teachers participating. The results of the data analysis show that the teachers participating in the activity: (1) are enthusiastic and communicative in participating in the activity, (2) can practice making Kopermatik mathematics teaching aids with quite good and varied results, (3) give positive response to the usefulness of Kopermatik teaching aids, and (4) more than 65% of teachers were able to answer each evaluation question correctly

Abstract

the engagement activity begins with the development of technology and communication, as well as the high demand for mathematics learning media by teachers. On the other hand, the quality of education, particularly in junior high schools, is still low. Teachers' competence, especially in media usage and development, is also low. Therefore, a workshop on media development will be conducted to enhance teachers' competence and the availability of learning media. The implementation methods for this engagement activity include material presentations, demonstrations, practical exercises, group discussions, and evaluation with feedback. The results of this engagement activity show that the majority of junior high school teachers in Central Lombok believe that the use of Geogebra and augmented reality in mathematics learning has the potential to improve students' understanding of concepts, interest, motivation, creativity, and learning outcomes. Teachers also acknowledge the importance of their role in effectively integrating this technology. Thus, the use of Geogebra and augmented reality-based learning media can provide positive benefits in enhancing the quality of mathematics education in schools. It is important to consider contextual factors and readiness when implementing Geogebra and augmented reality. The utilization of technology, especially Geogebra and augmented reality, should be tailored to the needs, availability of resources, and characteristics of each educational level.

Abstract

Number sense is important to be mastered by a prospective mathematics teacher as a basis for learning mathematics and makes it easier to train students' flexibility in solving math problems related to numbers. However, the results of preliminary studies show that there are indications that the prospective teacher's ability to operate numbers is not good enough. This study uses quantitative methods that aim to investigate the number sense component of mathematics teacher candidates who are still weak. The respondents involved in this study were 36 students who were prospective third-year mathematics teachers who had taken linear algebra courses. The instrument used is a 30-item number sense problem developed based on the number sense component, namely understanding and skills about numbers, understanding and skills using number operations, and applying number skills and operations in computing. This number sense test is done for 30 minutes. The results showed that the number sense ability of prospective mathematics teacher students was average with an average percentage of correct answers of only 51.57%. The third component in number sense is the weakest mastered with a percentage of correct answers of only 46.39%.

Abstract

This paper investigates the determination of the partition dimension for a \emph{bridge graph} formed by connecting a clique $K_n$ and a star $K_{1,m}$ through a single edge. Although the partition dimension has been extensively studied for various families and graph operations, the mixed dense--sparse case on $B(K_n,K_{1,m})$ remains unsettled, since the result is sensitive to the position of the bridge edge and the balance between the size parameters $n$ and $m$.We combine distance symmetry arguments, leaf-based constraints at the star center, and explicit constructions of distinguishing partitions to obtain tight values of the partition dimension. The study begins with the basic cases $K_1$ and $K_2$, and then proceeds to the general case with parameters $n\ge 2$. The main result shows that for the \emph{central bridge} ($e=v_1x$), it holds that $pd(B)=n-1$ if $m<n$, $pd(B)=n$ if $m=n$, and $pd(B)=m$ if $m>n$; for the \emph{leaf bridge} ($e=v_1u_1$), it holds that $pd(B)=n$ when $m\le n$, and$pd(B)=m-1$ when $m>n$. These results demonstrate that the location of the bridge edge, together with the size parameters $m$ and $n$ of the components, can sharpen the partition dimension value of the graph prior to the bridging operation.
