Authors: Rukmi Dwi Kartika
Published: May 2022

Abstrak: Kanker payudara (KP) merupakan kanker dengan insiden tertinggi untuk semua jenis kanker di Indonesia. KP di Indonesia seringkali ditemukan sudah dalam stadium lanjut dan sudah sulit untuk dilakukan pengobatan. Tindakan skrining dini perlu dilakukan untuk mendeteksi sel-sel abnormal sebelum berkembang menjadi kanker yang mematikan. Sebelum menuju kearah skrining kanker payudara, masyarakat perlu untuk diberikan pemahaman terkait dengan KP, hal ini dikarenakan pemahaman yang rendah dapat menjadi faktor yang berkontribusi terhadap peningkatkan kejadian KP. Edukasi KP dilakukan pada wanita di Desa Singkil Wetan untuk mengetahui tingkat pengetahuan sebelum dan sesudah diberikan edukasi. Hasil kegiatan edukasi mendapatkan bahwa nilai pretest sebelum edukasi rata rata 51,5± 4,95 dengan nilai minimal-maksimal adalah 43-61.  Setelah diberikan edukasi didapatkan ada perbedaan signifikan (pv:0,000) untuk tingkat pengetahuan KP dibandingkan dengan tingkat pengetahuan sebelum mendapatkan edukasi. Dimana nilai posttest didapatkan rata rata 58,7 ±3,78 dengan nilai minimal-maksimal adalah 46-62. Kategorisasi tingkat pengetahuan sebelum edukasi didapatkan sebanyak 53,8% peserta berada pada kategori sedang. Setelah edukasi, sebesar 96,2% peserta berada dalam kategori tinggi untuk tingkat pengetahuan terkait kanker payudara.Abstract: Breast cancer (BC) is cancer with the highest incidence in Indonesia. BC is often found in an advanced stage and is already in a problematic condition for treatment. Early detections need to detect abnormal cells earlier before they develop into deadly cancer. Before heading towards BC screening, someone needs to understand BC itself; because low understanding can contribute to the increasing of BC incidence. BC education was carried out on women in Singkil Wetan Village to determine the level of knowledge before and after being given education. The educational activity found that the average pretest score before education was 51.5 ± 4.95 with a minimum-maximum score of 43-61. After being given education, it was found that there was a significant difference (PV: 0.000) for the level of KP knowledge compared to the level of knowledge before receiving education. The post-test score obtained an average of 58.7± 3.78 with a minimum-maximum score of 46-62. The categorization of the level of knowledge before education was found that 53.8% of participants were in the medium category. After education, 96.2% of participants were in the high category for knowledge related to breast cancer.
Pode mexer ou é para enfeitar a sala? Utilização de material manipulável para ensino de Geometria nos Anos Iniciais do Ensino Fundamental
Authors: Oliveira George William Bravo de , Izar Soraya Barcellos , Settimy Thaís Fernanda de Oliveira
Published: May 2022

As conversas entre os professores, participantes do curso - Visualização em Geometria nos Anos Iniciais do Ensino Fundamental - promovido pela Sociedade Brasileira de Educação Matemática em 2021, despertaram a atenção a respeito do uso de material concreto nas escolas. Algumas escolas não possuem material disponível e em outras esses materiais são subutilizados ou não são empregados nas práticas de sala de aula por conta de os professores não saberem como utilizar. Neste artigo abordamos algumas possibilidades e colocamos a disposição referências de professores que adotam essa prática em suas experiências profissionais. A visualização é uma habilidade que precisa ser desenvolvida desde as séries iniciais do Ensino Fundamental, para tanto, se inicia com a manipulação de materiais concretos pela observação e percepção o que favorece a criação de memórias que ativam a imaginação. A visualização não é de aplicação exclusiva da Matemática, mas confere ao ser humano a capacidade de integrar conhecimentos escolares e a vivência fora da vida escolar. Explorar os materiais manipuláveis associando-os aos tópicos de Geometria, não apenas pelo estudo da disciplina em si, mas explorando os conceitos geométricos, observando a aplicação desses conceitos e identificando-os nas diversas situações presentes no dia a dia. Isso é fundamental para a construção do processo de visualização dos estudantes desde os anos iniciais do Ensino Fundamental.

Authors: Kudrynetskyi R. R. , Dnes V. , Pogorilyy S. , Krupych S.
Published: May 2022

Annotation
Purpose. Analyze current trends in the grain market, which will allow to the determine factors that shape the situation in the grain market.
Methods. In the course of the research, the methods of monographic, system analysis and synthesis were used.
Results. After analyzing the world grain market, it was found that the restraining factor for grain exports is the domestic transport and logistics infrastructure, which operates with low efficiency of grain processing and transportation. Therefore, the contradiction between the pace of development of grain farming and transport and logistics infrastructure is becoming an urgent problem and needs to be resolved at the state level through the improvement of the mechanism for regulating the grain market.
Conclusions. The growth of demand from 191.5 million tons for 2019/20 MY to 193.8 million tons for 2020/21 MY in the world grain market encourages domestic producers to increase production. Over the past five years it has grown from 60125.8 thousand tons in 2015 to 64933.4 thousand tons in 2020. When storing grain at 84 million tons, the deficit of power of elevators is 50 %.
A deterrent for grain exports is a domestic transport and logistics infrastructure operating with low grain transportation efficiency.
Keywords: market conditions, grain market, grain production, grain prices, demand, supply.
Hess Law Applicability to Heterogeneous Combustion Reactions Resulting to Non-Monotonicity of Enthalpy Distribution in Them
Authors: Filimonov I. A. , Filimonova I. I.
Published: May 2022

The definition of reaction irreversibility (reversibility) available now in literature does not allow for determining this reaction peculiarity before a practice. Moreover, in mathematical terms, such a definition is not universal and leads actually to the denial of any similarity in physicochemical processes, in particular in combustion waves. We have considered the irreversibility of reactions from the mathematical viewpoint as independence of a reaction rate on the concentration of products directly. As a result, in terms of Lei numbers, we have formulated conditions sufficient for the enthalpy of reagents to be a complete differential (or a thermodynamic potential) and independent of the reaction path. And conversely, the conditions necessary for that enthalpy of reagents are significantly dependent on the reaction path (Le ≌ 1). A comparison of the conclusions we obtained with the data from experiments available in the literature showed a good agreement with them and put an edge on the question of determining the irreversibility (reversibility) of reactions in the scientific community. We have shown that the small values of the diffusion coefficients of reagents Di compared to the thermal diffusivity coefficient κ, and with them, the corresponding small Lewis numbers (Lei = Di/κ << 1) for the most heterogeneous combustion synthesis systems, are the sufficient conditions for the enthalpy of reactions (H) to be a complete differential of the systems states and, vice versa, a strong similarity appears between the enthalpy and concentration fields at Le ≌ 1.

Synthesis and characterization of hexamine capped ZnSeO4 QDs (ZnSeO4-Hex) by heating up method (HU) was achieved. These, of two crystallite sizes, denoted QDsS1 and QDsS2; with crystallite diameters of 8.6 nm and 14.0 nm respectively. X-ray diffraction (XRD) pattern bared hexagonal close packed (hcp) crystal structure. Band gap for QDsS1 was 5.85 eV and for QDsS2 3.8 to 4.3 eV. Hexamine (C6H10N4) cap on ZnSeO4 QDs was elucidated by Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography-Mass Spectroscopy (GC-MS) results. Transmission Electron Microscopy (TEM) images revealed polycrystallites of different orientation, showing crystal grains separated by tilted grain boundary folds. These QDs were tested as optical chemical nano-sensors for carcinogenic organic pollutants: Anthracene (ANTH), Benzo (a) pyrene (BaP), pyrene (PRN) and pyridine (py). Results revealed that, when the organic pollutants interacted with the QDs, they caused characteristic changes in the way these nanoparticles interacted with characteristic fluorescence and absorbance spectrum

Authors: KRUSHYNSKA Alla , KRAVETS Iryna
Published: May 2022

The article is devoted to the study of the peculiarities of the development of the pension system in Ukraine and the characteristics of its three levels. The state and problems of functioning of the first level of the pension system (solidarity) are characterized, the forecast of its development is made taking into account demographic changes and deficit of the Pension Fund of Ukraine. An analysis of the dynamics and structure of revenues and expenditures to the budget of the Pension Fund of Ukraine for 2017-2020 and a comparison of expenditure and revenue of the budget as a whole are committed. Changes in the minimum pension in Ukraine and its inability to ensure a decent standard of living when reaching retirement age are studied, based on which the relevance of launching the second level of the pension system and the transition to personalized funded pension accounts of employees are justified. A number of unresolved problems of launching the second level of the pension system in Ukraine are outlined and the main ones are singled out. Prospects for further development of the third level of the pension system are considered. The main indicators of activity of non-state pension funds and tendencies of their further development are given. A comparison of payments from the State Pension Fund of Ukraine and non-state pension funds with a conclusion on the growing relevance of the latter and their strong investment potential for the Ukrainian economy are carried out. The place and role of life insurance in the pension savings market are highlighted. The advantages of the pension insurance system in comparison with the existing models are substantiated. The calculation of the pension in the insurance company as an alternative method of long-term accumulation is conducted. The high prospects for the accumulation of pension capital to achieve prosperity through the system of non-state pension insurance are argued. Recommendations for reforming the pension system in Ukraine are given. The directions of state support of the third level of the pension system are substantiated, namely accumulative life insurance and its positive impact on economic processes in Ukraine, reduction of social tension and indirect reduction of budget payments to socially vulnerable groups.

The problems posed by migration and the processes that affect its spread are identified in the article. Labour migration occupies an important place in state regulation in Ukraine. The authors focus on the implementation of state migration policy, local government reform, decentralization of power relations. Research papers on the implementation of state migration policy, the activities of public authorities at the local level, the providing of administrative services have been studied. Certain powers, including the providing of administrative services, have been transferred from the central level to the local level. Administrative services are provided through administrative service centres. Administrative services are classified into groups. Some aspects of normative-legal, institutional and other providing are revealed. Attention is paid to the development of electronic services in the sphere of migration. The state of provision of public services by the public authorities to the population in the sphere of migration is analysed. The problem of internally displaced persons from the temporarily occupied territories of the Autonomous Republic of Crimea, Donetsk and Luhansk oblasts is emphasized. The article presents information on the provision of administrative services to internally displaced persons by the territorial bodies of the State Migration Service of Ukraine. The authors present data on administrative services provided on the example of Vyshhorod regional branch of the State Migration Service of Ukraine in Kyiv and Kyiv region. The results of the survey on the quality of receiving administrative services by the population are presented. It is noted that to ensure the availability of administrative services there is a need to implement modern methods, mechanisms, tools and technologies for implementing public policy with the involvement of representatives of public and business environments. Personnel issues, which will be the subject of further research, remain urgent.

Authors: Abu Qouder Fouze , Amit Miriam
Published: May 2022

Our study attempted to address young Bedouin (desert tribes) students’ persistent difficulties with mathematics by integrating ethnomathmematics into a standard curriculum. First, we conducted extensive interviews w 35 Bedouin elders and women to identify: 1. The mathematical elements of their daily lives- particularly traditional units of length and weight, 2. The geometrical shapes in Bedouin women’s traditional dress embroidery. Then we combined these with the standard curriculum to make an integrated 90 hours 7-8th grade teaching units that were implemented in Bedouin schools and in the Kidumatica Math Club for Excellent Students. Comparisons between the experimental groups (186) and the control group (62) showed that studying by the integrated curriculum improved:1.The cognitive aspects of the students 2.The affective aspects.

Why Everyone should know Statistics!
Authors: Adams Nadine , Hayes Clinton
Published: May 2022

“Decision is the central intellectual activity in our everyday lives” and statistics is central to these activities (Longford, 2021, p. xi). The ability to manipulate and interpret data is an important component in decision making. A misunderstanding or poor grasp of data distributions and statistical methods can lead to assumptions that are not accurate. When these inaccurate assumptions are presented as factual to decision makers also possessing little or no statistical knowledge, poor decisions can be made. This paper investigates how an interpretation of statistics played a role the decision to remove multiple-choice questions from invigilated examinations at a regional Australian university. The case is further argued that it is important for everyone to have a basic understanding of statistics.
The Perspectives of Effective Teaching and Learning of Current Undergraduate and Graduate Mathematics Students
Authors: Alexander Anita N.
Published: May 2022

Some mathematics professors engage their students in discourse and explorations to promote a deep understanding of critical concepts. Still, lecture remains the norm in mathematics courses according to current mathematics students’ survey responses (Mostly Lecture 52%; Lecture & Discussions 35%; N = 89). Students were asked the best way for them to learn mathematics, whether their career plans are teaching related (Teaching Related: Yes 22%; Not Sure 36%; No 42%), as well as what they enjoy and want to change about their mathematics courses. Students requested “more discussions, and more questions to solve in class,” and described lecture as “an unacceptable way to teach,” and that “it is the worst way to learn.” Students’ perspectives on effective teaching and learning are critical for their continued passion to pursue STEM related fields, rather than stating that “I do not love mathematics anymore.”
Find out Mathematics on a Football: Making a football with paper
Authors: Aoki Takako , Watanabe Shin
Published: May 2022

We are aiming for a workshop method as a way to teach mathematics in future school education. It is important to cooperate with each other and understand mathematics. In this workshop, we aim to discover the mathematics hidden in the footballs we handle every day. As an aid to thinking, I would like to make football by paper first and learn mathematics while looking at concrete things. You need 20 equilateral triangles. A regular hexagon is made from this equilateral triangle, and a regular pentagon uses the method of making a hole. In particular, pay attention to the four-color problem in mathematics, make sure that the colours of adjacent regular hexagons are different, and use three colours (red, green, yellow). For example, in a football, how many equilateral triangles of each colour are used is one of the issues. I am looking forward to holding a workshop to see what kind of problems there are. Key words: football Introduction with paper, the truncated icosahedron, the color coding of the three colors, Euler's polyhedral formula
Analysing the Demands of an Assessment in a Geometry Pedagogic Content Knowledge Module
Authors: Bansilal Sarah
Published: May 2022

With the onset of the pandemic, universities were forced to move to online platforms for teaching and for assessments. In this paper, I reflect on the use of multiple-choice questions in a geometry PCK module for pre-service mathematics teachers. The study involves a secondary analysis of the data generated by the responses of 92 students to an assessment consisting of 25 items. The aim of the study was to distinguish between, and if possible, characterise possible levels of demands of the test items. The results suggested that there are four distinct groups of items relating to common content knowledge of early and late high school respectively, PCK related to deductive reasoning skills and critical thinking in an open book setting.
Promoting Meaningful Conversations among Prospective Mathematics Teachers
Authors: Bonaccorso Victoria , DiNapoli Joseph , Murray Eileen
Published: May 2022

Recent circumstances due to the COVID-19 pandemic and restrictions on entering public schools have created barriers for prospective teachers (PT) to gain valuable exposure to real classrooms. As a result, we have transitioned some teacher preparation from in person experiences to video case study analysis. Our research seeks to determine how this transition can foster development of critical teaching skills by infusing a model of powerful teaching with video of real classrooms. Our findings suggest that with online video case analysis PTs were able to advance their discursive conversations to strategic conversations by building on and transforming each other’s articulation of proposed teacher moves. This model for PT preparation has the potential to foster more meaningful discourse among participants by providing a space to build on and refine their understanding of mathematics teaching.
Introducing Symmetry and Invariance with Magic Squares
Authors: Brasili Simone , Piergallini Riccardo
Published: May 2022

Magic squares are key tools in mathematics teaching. They favor reasoning and creativity in problem-solving. As well, they bring students closer to the history of mathematics. Our work presents the magic squares in a learning progression introducing the symmetry linked with the idea of invariance “sameness in change” early at primary school in Montegranaro (Italy). Using the 3x3 magic square and manipulation games, a sample of 101 pupils (8 years) internalizes symmetries, reflections, and rotations associated with the square. The proposed activities provide tools and experience for geometric cognitive processes transferable from magic squares to main geometric shapes. The findings confirm that symmetry linked to the search for invariance is appropriate and accessible for primary school pupils through manipulation games.
Connecting Mathematics to the World: Engaging Students with Data Science
Authors: Burrill Gail , Dick Thomas
Published: May 2022

Mathematics and statistics can be used to describe, explore, and understand this complicated world in which we live. The workshop focus is on several potentially messy, real-world problems from predicting herd immunity, to exploring the quality of life across countries to modeling the change in CO2 levels. Each situation begins with a question and a set of data. The activities are open ended with multiple ways students might develop mathematical and statistical models, use technology to analyze the data, and make sense of terms such as herd immunity or vaccine efficacy or to investigate situations such as optimizing resources during a flood.
The Adventure of Learning Mathematics and Lakatos’s Legacy
Authors: Camou Bernardo
Published: May 2022

mathematics is a human creation and thus we can ask: How can humans with flaws and defects are able to create something perfect and infallible? Mathematics have its foundations in concrete problems, trials and errors approximations and representations. Learning mathematics is a fascinating trip, back and forth between concrete and abstract, between approximations and accuracy, between particular and general. Our poor representations are the road to conceptualize mathematical objects that then, seem to become perfect. In this workshop we will handle polyhedral and work with Euler’s Formula, with angular defects and its relation with surface´s curvature. In Lakato’s book Proofs and Refutations the author might have committed a mistake, though his book gives us a brilliant insight about the logic of mathematical discovery.
Fractions of the Future
Authors: Cotter Clayton Kathleen
Published: May 2022

Explore the simplicity and beauty of fractions of the future with a linear model, not with circle sets. When fractions are approached with this linear perspective, fractions can be easily taught, explored, and applied in daily life. Learn how to ask the right questions to guide your pupils to a solid understanding. Children as young as five can see that 1/3 is less than 1/2 and more than 1/4. They can also see why 9/8 is more than 1, why 1/4 plus 1/8 is 3/8, and why 1/2 × 1/2 is 1/4. Fractions are a delight when they are taught the right way. Allow the children to explore the whole picture and relationships within the whole using the linear fraction model. Learn about activities and games to build confidence and develop a deep understanding of fractions. Uncover the joy of fractions!
Teaching Primary Mathematics without Counting and Place Value with Transparent Number Naming
Authors: Cotter Joan A.
Published: May 2022

Counting - memorizing the sequence and coordinating pointing with recitation - is problematic for many children. Children with poor counting skills often struggle to learn their beginning math with various approaches. Yet, counting is unnecessary. Babies are born with the ability to subitize; that is, to detect quantities at a glance, up to three. By age 3, they can subitize up to five; by age 4 they can subitize up to 10 by grouping in fives, similar to their fingers. After children know the names for quantities 1 to 10, their next step should be place-value starting with temporary transparent number naming. For example, 11 is “ten-1”, 12 is “ten-2”, and 24 is “2-ten-4.” The counting words in Far Asian languages reflect this transparency, enhancing their pupils’ mathematics achievement. Place-value knowledge combined with subitizing gives pupils a way to master number combinations.
The Impact of Remote Instruction on Mathematics Teachers’ Practices
Authors: Courtney Scott A.
Published: May 2022

The coronavirus pandemic has impacted all aspects of society. As the virus spread across the globe, countries and local communities closed workplaces, moved schools to remote instruction, limited in-person contact, cancelled public gatherings, and restricted travel. At one stage, over 91.3% of students worldwide, from pre-primary through tertiary education, were impacted by school closures. In the United States, many institutions continue to provide remote and hybrid learning options throughout the 2021-2022 academic year. Attempts to mitigate Covid-19 through mass remote instruction has provided unique opportunities for researchers to examine the resources teachers utilize to drive and supplement their practices. In this report, I describe remote instruction’s ongoing impact on grades 6-12 mathematics teachers and their students in rural area and small-town schools in the Midwestern United States.

The author has developed and taught a course for University students who are not specializing in mathematics, science, or engineering. In contrast to traditional courses of this type, this course focuses on topics from the real world that students will encounter in later life. The aim of the course is to provide students with mathematical tools that they can use to create meaningful, practical solutions to problems that arise in these topics. Students work individually on projects and present their solutions in class. Other students then critique these solutions. With practice, students develop the skills necessary to analyze more complicated kinds of problems. A final project enables students to use their newly acquired techniques to deal with more realistic problems. The author discusses the content of the course and the impact it has had on students.
Math Modelling: Common Pitfalls and Paths for Student Success

Mathematical modelling refers to the process of creating a mathematical representation of a real-world scenario to make a prediction or provide insight. There is a distinction between applying a formula and the actual creation of a mathematical relationship. Approaching open-ended problems can be challenging for students. In this two part workshop, we first share examples of how students can get off-track while creating models, in particular making choices or assumptions that undermine the solution quality. In the second part, we demonstrate how to facilitate authentic math modelling so that students can be creative and innovative in the modelling process while having ownership over their solution. Participants will assess real student modelling solutions from Mathworks Math Modeling Challenge (M3 Challenge), a program of Society for Industrial and Applied Mathematics (SIAM), and discuss ways that they would advise teams towards improvement.
Modelling Beauty: Hands-on Experiences in Group Theory
Authors: Glynn-Adey Parker , Mamolo Ami
Published: May 2022

In the 19th century, geometric models were valued as tools for exploring complex mathematics. Quartic surfaces and hyperboloids elaborately modelled with plaster gave access to powerful ideas and brought alive wonderful new mathematics. In this workshop, we explore a diverse set of geometric models that capture mathematical beauty and we showcase how they can be used to bring alive wonderful new-for-students mathematics. We discuss the value of these experiences for fostering mathematical ways of being that can help disrupt preconceived notions about a homely, rote and rigid nature of mathematics, and capture some of the visual richness of older mathematical models.
Reuniting Exponents and Logarithms: Teaching Exponents, Inverse functions, and Logarithms, as one Cohesive Pedagogical Unit
Authors: Gordon John
Published: May 2022

Exponents, inverse functions, and logarithms are fundamentally important concepts in almost every branch of technical science. However, they are not taught together as a cohesive, comprehensive, pedagogical unit in many instances. As a result, students lose deep insight into their meaning and applicability. Additionally, particularly in the concept of the inverse function, the richness, and beauty inherent in the concept are reduced to a purely mechanical process. This paper seeks to remedy this situation by outlining a pedagogical strategy that links exponents, inverses, and logarithms together in such a manner as to preserve their natural dependence, coherency, and logic. Keywords: Exponents, inverse, functions, logarithms.
Infographics to Develop Graphical Literacy
Authors: Hydorn Debra
Published: May 2022

Tools for easily creating infographics are widely available, both online and through statistics, mathematics, and other programs. Determining the appropriate graphs to produce for different kinds of data is an important skill for students at all levels to learn, as is determining the best graph for a specific audience. With the increased availability of data comes the increased expectation that researchers in all disciplines can effectively communicate their findings to a wide range of audiences. Experts in graphical design have defined aspects of “graphical excellence,” but the effectiveness of graphically portrayed information depends a great deal on the needs and abilities of the intended audience. To create effective graphs, students not only need to be familiar with tools for creating graphs, they also need to be familiar with the communication, cognitive, and aesthetic principles associated with infographic design.
Combining Various Data Mining Techniques in Binary Classification Teaching
Authors: Khalemsky Anna , Stukalin Yelena
Published: May 2022

Binary classification is one of the most common data analytics tasks. It appears in a wide range of applications including finance, sociology, psychology, education, medicine, and public health. In statistical and analytics courses, binary classification is usually handled by logistic regression. Other alternatives, such as decision trees, neural networks, and Naïve Bayes are not commonly taught in traditional undergraduate programs. We suggest making these methodologies accessible as alternatives or complementary approaches to binary classification. We treat the teaching of the subject as a dynamic process that involves the understanding of the analytical task, understanding terms and concepts, visualizing, analyzing, interpreting the results, and decision making.
Magic Throughout the Years
Authors: Kroesch Allison M. , Otto Albert
Published: May 2022

Too often teachers use the word “trick” in their mathematics lessons. There are no tricks in mathematics, but there are explanations for what appears to be a trick. Throughout this paper, we will address this history of magic, including the history of playing cards.
Support for Mathematics Teachers through Representations of Practice - Vignette-based Approaches in the Project coReflect@maths
Authors: Kuntze Sebastian , Friesen Marita , Krummenauer Jens , Skilling Karen , Fernandez Ceneida , Ivars Pere , Llinares Salvador , Samkova Libuše , Healy Lulu
Published: May 2022

Teachers' analysis of vignettes can be a key for connecting specific classroom situations with mathematics education theories. As vignettes are representations of practice with relevance for professional requirements of the mathematics classroom, vignettes also represent or portray meaningful theoretical elements. The use of vignettes in pre-service and in-service teacher professional development needs, however, conceptual and evidencebased exploration. Building on prior work with video, text, and cartoon vignettes, the project coReflect@maths aims at exploring the potentials of vignette-based work both for supporting professional learning and for research into aspects of mathematics teachers' expertise. Key aspects of the project work will be presented.
Undergraduate Research in a 2-Year College: Climate Change, Global Learning, Process and Observations
Authors: Leitherer Barbara H. , Dwarka Pankaj R. , Xhane Entela K. , Rami Jignasa R.
Published: May 2022

In order to thrive and be successful in an increasingly interconnected world, 21st century students require multiple opportunities to engage with global learning (Landorf et al., 2019). Mathematics faculty guided 2-year college honors students in the US through an independent study analyzing real-world global climate change data supplied by the World Wildlife Fund (WWF). This proposal will elaborate in depth about the undergraduate research process, lessons learned, and observations made. Presenters will reflect on strategies used to support both collaborative and independent learning; how students increased their awareness of climate change as a global problem; how this contributed to students’ ownership, success and enhancement in undergraduate research leading to preparedness for further education and a successful career in science, technology, engineering, and mathematics.

Published: May 2022

We describe three Mathematics Education initiatives launched as a result of the global pandemic. (i) The Eastman-funded MathElites professional development (PD) program for K-8 teachers was offered online. Teachers were vastly more involved due to their greater autonomy. Old outcomes and those from 2020 will be compared. (ii) ETSU’s Governor’s School, which offers high school students Statistics and Biology college courses, went online too, and we used Columbia University Virology lessons and Covid19 data sets to make the courses more engaging to students. Student projects were assessed to be of a higher quality than in years past. (iii)With Niswonger Foundation support,we have launched a PD thrust for teachers in 2021, in the new areas of Epidemiology, Artificial Intelligence, and Statistics-with-R.
Professional Mathematical Modelling: What we can Learn about Teaching Real World Mathematics from the Real Application of Mathematics in our World?
Authors: Maaß Jürgen
Published: May 2022

lessons, more motivation and a more sustainable learning success. Professional mathematical modelling is an important foundation for modern, technology-based societies. We are all significantly influenced by the results of mathematical modelling. The decisions for lock down, masks and travel restrictions in connection with Corona are a current example. This article drafts what we as teachers & researchers can learn about successful mathematical modelling from professional working mathematicians who are using & applying mathematics in the natural sciences, technology development, medicine, economics, social and humanities research & practice, consultancy for politics, the financial world & other economic sectors). The background for this article is my research on mathematics as a technology, its acceptance as a concept and ways of technology transfer, as well as decades of experience with colleagues from industrial mathematics (https://www.indmath.uni-linz.ac.at/) and the RISC (https://www.jku.at/institutfuer-symbolisches-rechnen-risc/anwendungen/risc-software-gmbh/) who started their work here in Linz a long time ago. As a co-founder and co-organizer, I organized and enjoyed many lectures on mathematics and society, industrial mathematics, etc. at the Johannes Kepler Symposium (https://www.numa.unilinz.ac.at/JKS/2020/
