Abstract

Difficulty is the cause of errors, math errors refer to actions or results that do not follow the correct steps or procedures in solving math problems. Therefore, the purpose of this study is to describe procedural errors in solving social arithmetic problems using Polya's steps. In this context, procedural errors refer to mistakes made by students while following the systematic steps recommended by Polya, which include understanding the problem, planning a solution strategy, carrying out the plan, and reviewing the results. This study aims to identify where and how errors occur at each of these stages, as well as to provide a deeper understanding of the challenges faced by students in solving social arithmetic problems. This research used a qualitative approach with a case study design. The participants of this study were 22 students of class VII of State Junior High School 3 Satu Atap Tawangharjo. Data validity uses triangulation of methods, namely through interviews and observations, and source triangulation. Data analysis technique with the flow method of the Miles and Huberman model. The study found that students experienced errors at each stage of Polya's steps. The percentage of student errors at each step is as follows: 20% in the understanding the problem step, 30% in the devising a plan step, 35% in the carrying out the plan step, and 15% in the looking back step. Three students were selected as samples, S-1, S-2, and S-3, each showing errors at different stages. S-1 made errors in understanding the problem and devising a plan, S-2 in devising a plan and carrying out the plan, while S-3 made errors in carrying out the plan and looking back. This research will describe the problem-solving errors experienced by students based on each Polya step they perform.

Abstract

The use of textbooks or LKPD as learning media has several limitations, such as students' difficulties in reading and understanding content and a lack of interactivity, which may lead to boredom during the learning process. One promising technological solution to address these challenges is Augmented Reality (AR). This study aims to identify the common mathematical topics, learning models, and objectives frequently examined in research on AR-based mathematics education. The research methodology employed is a literature study, analyzing previous studies related to the integration of AR in mathematics learning. The findings indicate that the most frequently studied mathematical topic in AR-based research is geometry, particularly three-dimensional (3D) shapes, as AR allows students to observe and interact with geometric models more realistically. Additionally, the most commonly implemented learning models in AR-based mathematics education include inquiry-based learning and game-based learning. The impact of AR in mathematics learning includes enhancing student interest and motivation, deepening conceptual understanding, and increasing student engagement in the learning process.

Abstract

This study aims to produce Problem-Based Learning student worksheets (LKPD-PBL) on statistical material on the ability to understand mathematical concepts for class VIII SMPN 17 Bengkulu City, which are valid and practical. The urgency of this study is based on the importance of enhancing students' ability to understand mathematical concepts. Preliminary observations indicate that many students struggle to deeply comprehend statistical concepts due to conventional teaching methods. Therefore, an innovation in teaching materials is needed to help students develop their conceptual understanding through the Problem-Based Learning (PBL) approach. This study was a Design Research (DR) using type development studies, consisting of level preliminary and level prototyping with flow formative evaluation, self-evaluation, one-to-one, expert review, small group, and field test. The study instrument consists of a validity questionnaire, a practicality questionnaire, and interviews. The study results showed that the development of LKPD-PBL was: 1) valid based on the results of revisions through the expert review and one-to-one stages regarding aspects of material, construction, language, and readability; 2) practical based on the results of revisions through the small group stage regarding ease, clarity, and usefulness.

Abstract

In this paper, there is a section that identifies the aim of the research and makes it possible to suggest exploring the metric dimension and partition dimension of the amalgamation of complete graphs, which we would denote as Amal(Kn, v0)t. There are three steps conducted to achieve the research goals in this paper. To begin with, compute the lower bound of the metric dimension and the partition dimension of the graph Amal(Kn, v0)t. The second step is to find the upper bounds of the metric dimension and partition dimension of the graph Amal(Kn, v0)t by demonstrating that the representation of any vertex in Amal(Kn, v0)t is distinct. Finally, the exact values of the metric dimension and partition dimension of the graph Amal(Kn, v0)t are found if the lower and upper bounds are determined. The exact value of the metric dimension of the graph Amal(Kn, v0)t is denoted as dim(Amal(Kn, v0)t), while the exact value of the partition dimension is denoted as pd(Amal(Kn, v0)t). In this research, it is found that dim(Amal(Kn, v0)t) = (n - 2) for n, t ϵ N with n ≥ 3 and t ≥ 2. It is also found that pd(Amal(Kn, v0)t) = n for 2 ≤ t ≤ Cnn-1.

Abstract

Mathematical reasoning is an important aspect of mathematics education that involves logical thinking, problem analysis, and drawing conclusions based on existing data. Realistic Mathematics Education (RME) connects mathematical concepts with real situations that train students' logical thinking so that reasoning skills tend to improve. Therefore, it is important to analyze the development of RME research on reasoning skills. This analysis presents a bibliometric analysis of the literature on RME-based learning to improve mathematical reasoning, using data from Google Scholar accessed through the Publish Or Perish software and analyzed with the help of VOSViewer software. Through keyword searches for "RME" and "Mathematical Reasoning", 167 relevant documents were analyzed based on performance analysis, citation metrics, co-words, and co- authorship networks. The analysis reveals that publications on RME-based learning to improve reasoning skills have increased recently, although from 2008 to 2016 it was less than 4 per year. Indonesia has made significant contributions to RME research, with many of its authors actively involved in this field. The analysis identifies recent trends in advancing reasoning skills, including exploring topics such as the use of technology, media integration, hybrid learning models, and various approaches in RME-based teaching. In addition, this analysis highlights the potential for further research on the use of student worksheets as a widely applied learning medium in RME-based education to improve mathematical reasoning.

In 2022, the morbidity rate in Jambi Province reached 12.11%, higher than the previous year which was only 7.16%. The morbidity rate of the people of Jambi Province in 2022 increased by around 5% compared to last year. Based on the data on the morbidity rate of the people of Jambi Province above, it can be seen that the health condition of the people of Jambi Province has decreased compared to the previous year. By using the k-means method, this study aims to group the districts and cities of Jambi Province based on their health indicators as an effort to prevent a decline in health status in the coming years. As an effort to set priorities in improving public health in Jambi Province. The research resulted in three health clusters based on health indicator data. Cluster 1, which contains Sungai Penuh City, is at a high level, meaning that health conditions in the city are very good compared to other cities. Cluster 2, which consists of West Tanjung Jabung Regency and Jambi City, is at a medium level, meaning that health conditions in this city are quite good compared to other cities. Cluster 3 Kerinci, Merangin, Sarolangun, Batanghari, East Tanjung Jabung, Tebo, and Bungo are at the lowest level, meaning that health conditions in this cluster are poor and require more attention.
