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.

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.

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]

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.

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]

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]

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]

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.

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]

Mathematics as self-discipline is regarded to be one of the toughest subjects among students. To make this toughest to simplest, few things need to be cultivated inside you. Study habits are one of those things that have been found very useful in the academic success of a student. It is one key for a pupil to recognize and increase expertise in mathematics. These habits need to targeted and practiced at the early stages. There are higher probabilities that it would be a long-term asset for one. The current paper examined the impact of the study habits of school students on mathematics achievement. A sample of 200 students was chosen using random sampling from Government Senior Secondary Schools in Patiala District, Punjab. Questionnaires have been drawn to accumulate records of students' study habits. Students' outcomes in mathematics had been additionally been collected from their achievement in mathematics. Statistical tools has been used to analyze the data. It was concluded that students with good study habits exhibit higher mathematics achievement than students with low study habits. Besides, the authors also suggest how to develop good study habits among students. [ABSTRACT FROM AUTHOR]

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.

A method to study asymptotic properties of solutions to systems of differential equations with distributed time-delays and Boolean-type nonlinearities (step functions) is offered. Such systems arise in many applications, but this paper deals with specific examples of such systems coming from genetic regulatory networks. A challenge is to analyze stable stationary points which belong to the discontinuity set of the system (thresholds). The paper describes an algorithm of localizing stationary points in the presence of delays as well as stability analysis around such points. The basic technical tool consists in replacing step functions by the so-called “logoid functions” and investigating the smooth systems thus obtained. [ABSTRACT FROM AUTHOR]

In “Multidimensional Bernstein polynomials and Bezier curves: Analysis of machine learning algorithm for facial ex- ´ pression recognition based on curvature, Appl. Math. Comput. 344–345 (2019) 150–162”, some statistical evaluations on feature vectors were given in order to analyse their meaningfulness while classifying human facial expressions. In this paper, by using some results arising from SPSS program, we provide some further statistical evaluations and observations which are related to features based on the calculated Hausdorff distances between Bezier curves belonging to the regions that shape human facial expressions.

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]

This paper presents a preliminary result of ongoing research on monitoring natural disasters induce structural infrastructures damages by using off-the-shelf digital camera. It's Orientation and calibration algorithm that steamed from a more general pinhole camera model can be varied into two distinct approaches: projective collineation and perspective collineation which widely embraced by computer vision community and photogrammetric community respectively. This research investigates reliabilities of those varying methods for computing orientation and calibration of the captured images of a bridge. Some photographs of the surveyed bridge were processed using two proprietary software which each employs different collineation algorithm. Some findings reveal that the projective collineation algorithm uses more robust matrix operation but requires more parameters and consequently need more correspondent points on each captured image. On the other hand, fewer parameters and common points are required for the more rigorous perspective model although it requires a nonlinear relationship of matrix operations. Results show that the projective collineation algorithm gives higher model stability but requires more stable camera and optics. Furthermore, figures and numbers are provided to support our findings that both algorithms produce approximately equal precision of the orientation and calibration parameters. [ABSTRACT FROM AUTHOR]

In this paper we computed and studied the types of the subgroups of the groups A5, C2 × A5, C3 × A5, C5 × A5andCp × A5 where p is an odd prime number. We also classification the subgroups of those groups into the abelian, non-abelian, solvable, and non-solvable groups. So, we computed the number of solvability degree parameters of some of those finite groups. Mathematics Subject Classification (2010): 20F12, 20F14, 20F18, 20D15. [ABSTRACT FROM AUTHOR]

In this paper, we introduce notations of neutrosophic soft graphs, neutrosophic soft subgraphs and strong neutrosophic soft graphs. We also give some properties and related examples of them. [ABSTRACT FROM AUTHOR]

The aim of this study is to implement Fisher-Yates Shuffle Algorithm (FYSA) for randomization Math Exam in Computer Based-Test with fast execution time and can be generated without repetition and duplication. This study case in Management and Science University (MSU) Malaysia. This study used ADDIE model and develop based on a website framework using PHP as a back-end programming language, Java script as a client-side programming language, and MySQL as a database. The target population of this study was students in Bachelor Level at Management and Science University (MSU) Malaysia in Mathematics Subject. The subject will be focused on probability and statistics in one focus group. Mathematics lecturer also involved as expert in this study. There are seven questions set with a total questions N=15 on each set. The probability value of randomization the question set is 1/7 = 0.14285714. The permutation obtained from the randomization of Fisher Yates Shuffle is 15! = 1.307674368 x 1012. Based on the results of the quality test, it can be seen that all items of category regarding accessibility, helpful tools, and CBT content have an average percentage score 76.94%, these results mean that all CBT items are works well. That means the system will produce different random permutations each time students take question. [ABSTRACT FROM AUTHOR]

Studies found that the variables of student engagement at school and teacher support have a significant impact on mathematics achievement. This paper aims to examine the relationship between student engagement and teacher support on the mathematics achievement of Indonesian students. The data came from PISA 2018 Indonesia, which included 9,936 students from 354 schools who completed responses on the selected variables. The multilevel analysis revealed that student engagement at school, teacher support, and status of school were statistically significant to predict student mathematics achievement. Student engagement has a positive relationship with mathematics achievement as well as teacher support. The greater the number of students in public and private schools, the lower the mathematics achievement. There is a tendency for public schools to have higher scores than private schools.

In topological spaces, which are branches of pure mathematics, are difficult to find, the significance of this paper is to find some in graph theory via some topological space concepts, we introduced some well-known concepts in topology and related them to a graph such as (graph interior, graph closure, graph exterior, graph boundary and graph limit point). We study a characterization and relationships between them and present some results and theorems about this notions. In this work includes all Species graphs. [ABSTRACT FROM AUTHOR]
