In the current scenario Programming in Python plays a vital role in research arena as it preserves much of the man power. Converting the research work into the format of coding helps any researcher across the globe as it serves as a ready reckoner. Topology is one of the main branches of Mathematics. A Polish Mathematician named Kazimierz Kuratowski defined essential axioms in Topology with the aid of a closure operator named after him. In this paper, we have developed a Python program to find the closure and interior for the subsets of the given set. We will be using dictionary in Python with each subset as the key and the respective closure as its value. Subsequently we will be finding int(cl(A)), cl(int(A)), int(cl(int(A))), cl(int(cl(A))), for any subset A of the given set. [ABSTRACT FROM AUTHOR]

In recent years, with the increase of online learning platforms, obtaining learning behavior data from students, are becoming easy. However, analyzing the data to extract meaningful information remains challenging due to the data volume and complexity. Here, we apply Self-organizing Maps (SOM) to visualize the learning characteristics of many elementary students over many online assignments in mathematics class. As a case study, this research used the data log of MONSAKUN, a digital learning environment that focuses on exercising arithmetic using story-based questions by using a problem-posing approach with the integration of mathematical sentences. Our primary objective is to give intuitive understanding to the teachers regarding the students' performance that subsequently allows the teachers to generate meaningful advices. Here, SOM generates a two-dimensional map that preserved the topological order of high-dimensional learning characteristics data, in which students with similar learning characteristics are located close to each other, while students with significantly different characteristics are distanced from each other. We are interested especially in locating low-performing students, as they are the most important to be given advice by the teachers. By locating the low-performing students and other students in their vicinity on the map, the teacher may be able to use other students as references for improving the low-performing students' performances. The idea is to mimic the learning characteristics of the students designated as references. Due to the learning characteristics similarity, the low-performing students do not need to make drastic changes in their learning styles. It can be expected that by iterating this process over many assignments, the students' performances will gradually be improved. In this paper, we utilized a digital learning platform MONSAKUN, for learning arithmetic used in Japan. In this paper, we present our preliminary results in the form a learning-visualization of characteristics students of analytical and advisory tools and described our future goals for building a more flexible and general tool that can be deployed in Indonesia.

In the digital era, most of the human work is now been performed using the computer system. The computer's capacity to detect and understand meaningful Handwriting input from sources such as touch screens, pictures, paper documents, and other sources is referred to as handwriting character recognition. The diversity in people's handwriting style increases the complexity of handwritten characters. Also, grading academic answer sheets manually and providing an unbiased genuine grade is a challenging task. The aim of the work is to create handwriting character recognition system that will be used to read handwriting notes and solve mathematical equations. The ultimate goal is to show that neural networks can solve equations from a handwritten source effectively. In this paper, we present a web application-based equation solver that uses a camera image of an equation to display the solution. The program has the ability to solve simple arithmetic equations (addition, subtraction, multiplication) and up to two systems of linear equation variables handwritten or typed in a computer font.

This paper showcases an example of how mathematics was utilized to debunk a suspected anomaly in election returns in the aftermath of the Philippine national elections last May 2022. Initial results of the automated elections yielded numbers that the public deemed suspicious. In response to a call for experts' opinions on the matter, we processed and analyzed large samples of preprocessed data to which we have been given access. Using data analytics techniques, we examined transmission arrivals of election returns and compared them against the total votes transmitted, with the analysis performed at different aggregation levels. Our analyses showed that the seemingly suspicious numbers can be explained by examining the distributions of the transmission arrivals of election returns and analyzing those distributions using different levels of aggregation. From the perspective of critical mathematics education (CME) particularly, focusing on mathematics for critical citizenship, we highlight the importance of mathematics to help fight disinformation and spread of unfounded rumors. The paper concludes with recommendations for enriching students' mathematical experiences that could pave the way for a responsive and engaged citizenry in our country. [ABSTRACT FROM AUTHOR]

A teacher, who is the provider of the proven educational knowledge, should be adequately competent in terms of expertise, trust, dedication, positive attitude, effective communication and patient listening. All these attributes can surely be inculcated in pupil teacher but only if the training is provided with maximum commitment, with specified objectives, taking into account the needs of todays' educational scenario and the needs of students. This paper emphasize on the system of training being provided to pre-service Mathematics' teachers, to develop their teaching skills. It includes the use of some creative teaching concepts to increase the interest, level of satisfaction and the outcome of their targeted Mathematics' students. Several studies, researches have shown that the students, who have been studying Mathematics since their childhood, are unable to perform simple calculations and are unable to solve simple numerical problem of their everyday life. This study will conclude with some suggestive facts that pre-service trainees should be trained in a way that other than the prescribed curriculum/syllabus, they should spend time to improve quantitative skills using some innovative techniques in regular class practice. As an example, the inventive methodology will also be discussed. And the second highlight will be the the emphasis on continual and rigorous assessment of the trainees during teaching practice, so that they can resolve the dearth and can go ahead with a handful of approaches to serve the purpose of fruitful teaching and learning.

STEM education is one of the primary priorities in the Malaysian Education Blueprint (PPPM) 2013-2025, in line with the relevance of STEM at the global level. In keeping with the educational needs of 21st-century learning, the use of technology in education is also highly encouraged. Unfortunately, the Malaysian government's goal of producing one million experts in Science, Technology, Engineering, and Mathematics (STEM) by 2020 was not met because the 60:40 STEM: non-STEM policy failed to meet the goal. Students' interest in different STEM disciplines has been linked to their interest in integrated STEM in previous studies. Students' lack of interest in STEM fields appears to have an impact on their low mathematics achievement at the international assessment level, including in the field of geometry. Geometry is one of the most important branches of mathematics, and spatial thinking goes hand in hand with it. This paper presents the results of a critical review as well as a brief overview of ongoing research targeted at developing a model for the formation of interest among secondary school students in STEM through geometry learning based on augmented reality (AR) technology and visual-spatial abilities. The first part of the paper provides an in-depth review of these matters based on rather limited resources. The review revealed various difficulties and limitations in piquing students' interest in STEM and mathematics. The second part describes research being conducted by the researchers to examine the implementation of using AR in geometry learning based on visual-spatial abilities. For the pilot and main stages of the study, pre-and post-test, observations, and semi-structured interviews will be conducted. The data will be analysed quantitatively and qualitatively, and the theory of change approach will be applied. The findings will be used to develop a model for the formation of interests among students as a result of geometry learning. The model aims to provide some relevant information for technology-assisted mathematics instruction, and it aligns with national STEM policy goals of increasing the number of students selecting STEM disciplines in secondary and higher education.

This paper aims to describe mathematics teachers' perception of mathematical proof. Proving in mathematics for the teacher is crucial as the foundation of developing students' skills in generating correct proof to some conjectures which require good mathematical reasoning. It has been highlighted in some works of literature that mathematical reasoning which is closely related to proving in mathematics also contributes to the development of a chosen set of 21st-century skills. A total number 152 of Indonesian in-service mathematics teachers were given a survey concerning their perception of mathematical proving. The description of the result consists of five important categories including the process of mathematical proof, thinking ability in mathematical proof, appropriate school level in learning proof, topic, and understanding in a mathematical proof. It is found that Indonesian in-service mathematics teachers had a positive attitude towards mathematical proof as a teaching approach in their classrooms, as the opportunity for students to improve helped students improve their thinking ability.

The results presented in this paper are based on the research conducted during the last years. Many multi-disciplinary and practical mathematical-computational data and application solutions require to exploit holistically complex scenarios. In many cases, data and algorithms as well as workflows have to be created and tackled individually. The goal of this research is to create an innovative, comprehensive tool base of conceptual knowledge in mathematical-computational application scenarios for arbitrary knowledge context in any media. The solution should be complementary to the commonly available knowledge and features and should fulfill a range of further criteria, especially for a coherent system of knowledge, multi-disciplinary, and data-centric. The result should allow to create and refer to facetted knowledge focussed on mathematical-computational scenarios. The paper presents the results of an implementation based on the fundamental methodology of superordinate knowledge. The solution is targeting mathematical-computational application scenarios and has been used for many practical implementations over more than three decades. The resulting comprehensive subset of conceptual knowledge reference divisions, which was created from this long-term research, is available and first published with this paper.

In general topology, repeated applications of interior and closure operators give rise to several different new classes of sets. Someof them aregeneralized formof open setswhile few others are the so-called regular sets. These classes are foundto have applications not only inmathematics but even in diversefields outside the realm of mathematics [1–3]. Due to this, investigations of these sets have gainedmomentum in the recent days. Császár has already provided an umbrella study for generalized open sets in his latest papers [4–7]. In this paper, we introduce and study a new class of sets, called PS-regular sets, using semi-interior and semi-closure operators. Initially, we define them for a broader class, that is, for generalized topological spaces and discuss their various properties. Interrelationship of PS-regular setswith other existing classes such as semiopen sets, regular open sets, t-sets, α*-sets, B-sets, and C-sets has been studied. A characterization of semiconnectedness is also provided using PS-regular sets. Moreover, ξ-regular sets, where ξ∈ {α, β, π, σ}, of a generalized topological space are studied using PS-regular sets.

It plays an important role in the sense of connecting theoretical knowledge with practice. At the same time, it is one of the courses that specifically applies students' computer knowledge in solving mathematical problems. As a number of mathematical software and programming languages are emerging with the rise of IT technology, the question arises as to how to build the concept of teaching numerical mathematics. Models that have been used for a long time are already proving to be non-functional and significant innovation is needed. The paper will describe the structure of teaching numerical mathematics at the University of Ostrava, its innovations and teaching experience. [ABSTRACT FROM AUTHOR]

Mathematical representation is one of the fundamental abilities used in mathematics to build the connection between abstract ideas and logical thinking to understand and solve mathematics problems. The level of student representation ability will affect the way students convey the idea of solving mathematics problems. This shows how important this ability is in mathematics. But in fact, the ability of mathematical representation is felt to be less comprehensively mastered. This is indicated by the large number of students having difficulty conveying their ideas in solving mathematics problems. This paper describes students' abilities in mathematical representation to solve math problems. The indicators for mathematical representation ability in this research are classified as verbal representation (written text), visual representation (picture, diagram, graph, or table), and symbolise representation (mathematical statement, numerical/algebra symbol, mathematical notation). The subject of this research was 8-grade students of one of the junior secondary schools at Bukittinggi. The results showed that 22 out of 34 students have difficulty in conveying their ideas to solve math problems, while the rest feel quite good about it. [ABSTRACT FROM AUTHOR]

The effectiveness of Game-based Learning (GBL) in fostering students' motivation to learn mathematics is examined in this systematic review. Nine related papers published between 2018 and 2022 were found after an extensive search of the electronic databases of ERIC. A systematic review methodology was used to analyze the studies, and the results were then synthesized and summarized. None of the research in this review found evidence of a negative impact of GBL on students' motivation to learn mathematics; instead, all studies found evidence of a positive impact. It benefits students' motivation for several reasons, including the engaging and dynamic learning environment, the quick feedback and rewards, and the demanding and goal-oriented learning experience that games may give. The game's design, degree of difficulty, student autonomy, use of feedback and rewards, and other factors play significant roles in determining how effective GBL is at encouraging students' motivation to learn mathematics. However, this effectiveness is not guaranteed. The design and implementation of GBL in the mathematics classroom should consider these elements seriously. Generally, the results of this review point to GBL as a potentially successful strategy for increasing students' motivation to learn mathematics. Game-based Learning (GBL) is a strategy educators should consider employing to engage students and increase their interest in and love of mathematics. However, the game's design and other elements that may affect it must be carefully considered. More research is required to completely comprehend GBL's potential in mathematics education and develop efficient implementation methods. [ABSTRACT FROM AUTHOR]

Students' pattern of learning that does not involve active thinking will make it difficult for them to master the elements of higher order thinking skills (HOTS) in mathematics. Therefore, more effective learning methods need to be implemented to help students deal with this problem. This paper presents the results of a study after a cooperative method through paired learning was conducted on a selection of Year 6 students for the subject of Mathematics. The purpose of the study was to see the effectiveness of paired learning methods in the teaching and learning process of mathematics that apply the elements of HOTS. A total of twenty-eight Year 6 students from a school in Penang were selected as the sample for this study. Students' performance was tested before and after treatment to see if there was a difference between their performances. After that, a questionnaire was given to see the level of students' motivation and identify the factors contributing to their difficulties in mastering HOTS. From the results of this study, all students (100%) have shown an improved performance in the post-test. The mean scores from the questionnaire responses also indicated that students had a positive perception of the paired learning method. [ABSTRACT FROM AUTHOR]

Prior to the COVID-19 pandemic, majority of universities in Malaysia commonly implement the teaching and learning practices on physical face to face basis. However, the pandemic had drastically changed the norm of the teaching and learning practices into online teaching and learning as one of the measures to curb the spread of the virus among the community. The drastic move had greatly affected the academic communities particularly the students. Some of the possible factors influencing online learning difficulties faced by the students include poor internet accessibility, lack of self-motivation, lack of active interaction with lecturers and peers, lack of conducive learning environment and poor time management. In this paper, the technique of Fuzzy DEMATEL is employed in analyzing the level of influence and relationships of the aforementioned factors in contributing to learning difficulties particularly among fifty mathematic students at a public university in Shah Alam, Selangor, Malaysia. The cause-and-effect analysis that take into consideration the interactions or interrelationships between factors discovered that poor internet accessibility was classified in the cause group whereas the remaining factors which are lack of self-motivation, lack of active interaction with lecturers and peers, lack of conducive learning environment and poor time management were in the effect group. The results indicate that poor internet accessibility has the highest degree of relation in terms of influencing other factors. Based on the prominence value, the lack of self-motivation turns out to be the leading factor contributing to online learning difficulties. [ABSTRACT FROM AUTHOR]

Teaching and Learning Mathematics in the 21st centuries highly related to the digital technology used in the classroom. Mathematics is the best practice in the standard teaching and learning (T&L) process where the teacher and student physically attend the class. There is where the interaction and discussion on subject matter happened. However, due to the COVID-19, the practice needs to be changed drastically in which both sides of teacher and student are not allowed to have a physical class to avoid any contact. The learning process must proceed and adapt well to the current situation. A Learning Management system must be developed as a platform to digitally organize educational material. Due to that, this paper aims to illustrate the development of a website that is beneficial in T&L Mathematics courses. The content of the mathematics course chosen is Linear Algebra. There are various learning management systems, but the one that customizes the purpose and requirement of our class content can be developed by ourselves. Google offers a good package where google sites can be easily set up for that purpose. The content is arranged according to based on topics. In addition, the interactive learning environment is also embedded in developing the system to attract the student's attention during class hours. Live chat is also provided for the student to ask questions at their convenience time. Developing a customized learning management system can be an alternative for teachers to provide a digital environment to their students so that the process of T&L can be continued. Our website has been introduced to students, and their feedback is recorded. The result shows that students show positive responses while describing the website [ABSTRACT FROM AUTHOR]

Education for children with special needs, especially with mild intellectual disabilities, has not received much attention from researchers and practitioners. The education of intellectual disabilities children also has the same right to develop according to the needs of the times as regular children's education in general. The changing and evolving needs of the times should also be followed by changes in the curriculum used, considering that one of the learning goals in special schools for intellectual disabilities children is to make the children who can live independently. In special schools for intellectual disabilities children in Indonesia, mathematics learning is combined with other lessons to discuss specific themes in everyday life. Based on an extensive literature search on the mathematics curriculum in special schools for intellectual disabilities children, this paper aims to review the literature involving two things: (1) mathematics education curriculum in special schools for intellectual disabilities children in Indonesia, and (2) mathematics curriculum in special education in Australia and Singapore. A view is also provided. This paper concludes that: (1) learning in special schools for intellectual disabilities children in Indonesia uses thematic learning where mathematics learning is focused on its usefulness in everyday life, (2) numeracy is the focus of education in Australia, not least for intellectual disabilities children, and learning Mathematics for mild intellectual disabilities children in Singapore includes the concepts of numbers, spaces, arithmetic procedures, problem solving and measurement.

In this rapidly changing world, mathematicians are increasingly being relied upon to provide insightful analysis, theory and tools to address current and emerging problems. These problems include highly complex issues such as vulnerability to natural disasters, economic uncertainties, and environmental and health hazards. These are among the many pressing challenges to our region that require multi- and trans-disciplinary approaches. In addition, the advent of the Fourth Industrial Revolution, marked by data-driven technology and economy, and the pervasiveness of social media, are changing the landscape of academia. As we develop our research capabilities and improve instruction at all levels, a deeper engagement with different sectors and stakeholders becomes imperative. We need to strengthen connections with individuals and institutions, both within and beyond our discipline and respective communities. By building these bridges, we widen our influence, expand our horizons, increase our relevance, and collectively, achieve more. In this paper, I will reflect on these connections including the role of national mathematical societies and international organizations such as the Southeast Asian Mathematical Society and the International Mathematical Union.

Lie algebras appeared in mathematics at the end of the 19th century in connection with the study of Lie groups. A Lie algebra is a vector space over some field together with a bilinear multiplication is called the bracket which satisfies two simple properties: skew symmetric and Jacobi identity. The universal property of tensor product for representations of Lie algebras is a supporting conjugate of tensor product, which guarantees obtaining a linear map from a bilinear map. The main objective of the paper is to obtain results in representations for Lie algebra through the new structure consisting of four and five representations, by action of representation for Lie algebra. As well as obtaining new generalizations using dual action of representation for Lie algebra. [ABSTRACT FROM AUTHOR]

Nowadays, the need of ICT as a learning aid has potential role at the global scope. However, it sounds contradicts with the teaching and learning habit of the boarding schools or pesantren environment. It is an educational institution with strong and large cultural products, but reluctant to see the urgency of ICT implementation. This article aimed to examine students' learning experiences in mathematics at the role of ICT. The study was conducted using a qualitative approach with phenomenological methods. Research data were obtained through interviews and observations. Furthermore, triangulation of sources and triangulation of theory using Dale's classification or "the Cone of Experience" was carried out with regard to student learning experiences. The results showed that at this place: 1) the learning experience symbolically dominated the implementation of mathematics learning; 2) the iconic and enjoyable learning experience was only experienced by some students; 3) ICT had an important role in creating a symbolic, iconic, and enjoyable learning experience for students. This study provides strategic recommendations on how it can adapt the positive impact of ICT to support the learning process. While it deems impossible to stem the flow of ICT developments, this paper can serve as a reminder and a form of wake-up call to keep up with the demands and developments of the times. When ICT integration has not been implemented in mathematics learning, teachers should be able to create concrete learning experiences for students. [ABSTRACT FROM AUTHOR]
