FATORES DE RISCOS DE QUEDAS EM IDOSOS INSTITUCIONALIZADOS: UMA REVISAO INTEGRATIVA DA LITERATURA
Authors: Almeida Ludimilla Cardoso De , Gresik Karla Rocha Carvalho
Published: December 2024

This work aims to point out the main causes of falls in institutionalized elderly people, taking into account the hypothetical factors linked to the natural process of physiological aging, lack of adequacy of long-term care institutions, heavy use of medications, degenerative diseases and hereditary diseases. The study aims to identify the main causes of falls in the elderly, so that there is prevention and reduction in hospitalization. This is an integrative literature review with exploratory objectives through bibliographic research. The searches for articles took place in the main databases, Scielo, Lilacs, Pubmed with a time frame of ten years. The search results provided 49 articles, after going through the inclusion/exclusion criteria, 8 articles were selected for writing the results and discussion. Studies show that long-term care institutions are not prepared to receive these elderly people, due to a lack of infrastructure, inadequate ergonomics and the lack of assistance with a multidisciplinary team for the elderly.
A PRODUÇÃO DE “FALSAS” MEMÓRIAS NO PROCESSO PENAL: COMO OS ASPECTOS COGNITIVOS AFETAM A PROVA TESTEMUNHAL
Authors: Nascimento Caio Freitas , Gomes Junior Antonio Carlos de Sousa
Published: December 2024

O presente trabalho focará na produção da prova testemunhal, em especial, na possibilidade da criação de falsas memórias, aferindo se é possível que tal fato, seja tão crucial, que impacte o âmbito do processo penal, prejudicando a credibilidade dos depoimentos colhidos, bem como, os textos aduzidos a termo após a colheita da prova oral, na instrução processual penal. O presente trabalho pretende realizar um estudo sobre o paradigma de DRM aplicado em relação ao caso Washington x Steve Gary Titus (1980) e a influências das lembranças “criadas” pela memória, na produção da prova testemunhal e no processo penal. A pergunta que se pretende responder é: aspectos cognitivos do processamento da memória, pelo cérebro, podem influenciar a produção da prova testemunhal, no processo penal? A hipótese traçada é de que sim, a forma como a memória é produzida e armazenada pode influenciar a produção da prova testemunhal afastando-a da “verdade real”. O objetivo geral da pesquisa é identificar como esses aspectos cognitivos do processamento da memória, podem influenciar a percepção dos eventos pela testemunha, no que tange a sua contribuição no processo; enquanto que os específicos são compreender o Paradigma de DRM, conhecer o caso State of Washington x Steve Gary Titus (1980) e avaliar a prova testemunhal no processo penal brasileiro. Sobre a metodologia eleita, tem-se que após a escolha dos textos em repositórios públicos sobre o tema, foram realizadas resenhas das doutrinas das áreas técnicas de conhecimento do direito e do estudo da memória, utilizou-se o Paradigma de DRM, aplicado ao caso Washington x Steve Gary Titus (1980), numa perspectiva lógica decrescente, partindo dos conceitos abstratos da teoria, aos elementos concretos do caso, para em seguida promover as conclusões sobre a efetividade e legitimidade dos resultados obtidos no caso do estudo sobre os testemunhos produzidos.
AVALIAÇÃO DO DESEMPENHO DE FIBRAS NATURAIS EM COMPÓSITOS PARA CONSTRUÇÃO CIVIL NO BRASIL: SUSTENTABILIDADE E INOVAÇÃO
Authors: Ferreira Celina Lísia da Costa , Lima Laura Brito , Siqueira Ronaldo Alves
Published: December 2024

A sustentabilidade na construção está intrinsecamente ligada à seleção de materiais que sejam  duráveis, de baixo custo e que apresentem menor impacto ambiental, além de possuírem boas  propriedades mecânicas. A intensificação das alterações climáticas no globo e suas repercussões a  médio e longo prazo tem impulsionado cientistas e pesquisadores a explorar soluções para as nossas  construções através de materiais mais sustentáveis. Pesquisas voltadas para o desenvolvimento de  compósitos ecologicamente sustentáveis têm adquirido importância na construção civil, que visa  simultaneamente a outras metas atenderem o Objetivo 11 – Cidades e comunidades sustentáveis da  Agenda 2030 para os Objetivos de Desenvolvimento Sustentável (ODS). Nesse contexto, o uso de  fibras naturais surge como uma alternativa promissora para mitigar os referidos impactos como  emissão de CO2, degradação do solo com extração e despejo de materiais agressivos ao meio. Para a  avaliação dos teste, percebeu-se que com adição de 2% de bambu nos compósitos cimentícios não só aumentou a resistência do concreto, mas também elevou sua massa específica. Isso sugere que  o bambu pode contribuir para a melhoria da massa específica do concreto e, como resultado, para sua  resistência à compressão. Avaliou-se também a fibra de coco, e constatou-se a partir dos estudos que  a incorporação dessas fibras atuam como agentes de reforço, aumentando a resistência à compressão  do concreto e ajudando a controlar a propagação de fissuras, o que eleva sua tenacidade e ductilidade.  Além disso, a presença de fibras de coco reduz a absorção de água, contribuindo para a durabilidade  do material.

How is Virtual Reality (VR) Changing the Way We Interact with the World
Authors:   Lorong Seri Serdang, Kepala Batas, Pulau Pinang, Malaysia, Ganason Thanissa
Published: December 2024

Virtual reality (VR) is revolutionizing the way we interact with the world. VR is a simulated three-dimensional (3D) environment and a simulated experience that allows the user to explore and interact with the virtual environment to approximate reality and give the user the feeling of being immersed in a virtual world. It has gained amazing growth and popularity in transforming industries, such as entertainment, education, and others. Back then, learning was limited to textbooks and lectures. Complex topics were explained through static images and text. In addition, films were shown on flat screens. Interaction with video games was possible but was limited by the screen and remote controls. Nowadays, however, VR enables immersive excursions and 3D simulations for learning. This letter begins by discussing how VR is changing the way we interact with the world.
Artificial Intelligence in Drug Discovery: Transforming the Future of Medicine
Authors:   Former Research Scholar, Gurukula Kangri (Deemed to be University), Haridwar, Uttarakhand, India, Chawla Malvika
Published: December 2024

Artificial intelligence (AI) is one of the important tools in modern drug development processes, which can work through large bodies of data and build predictive models. This aids in identifying suitable drug candidates and predicting possible interactions between drugs and specific targets as well as exploratory therapeutic areas—all of which lead to a simpler and more efficient drug development cycle at minimal cost. In this review article, we examine the state of AI in drug discovery and discuss its applications where it provides support during target identification, validation stages including the drug-designing stage, as well as clinical research. This paper also discusses challenges associated with using AI in drug discovery, such as problems with the quality and interpretability of data/models or regulatory concerns. The review also considers the future of AI-driven drug discovery, with far-reaching implications for personalized medicine, and the expansion of therapeutic repertoire in recalcitrant diseases.
Asset Framing and Ethical Storytelling as Tools to Empower Communities and Reduce Stigma: An Examination of Virginia SNAP-Ed Reporting Practices
Authors: Reitmeier Ella , Zeide Anna , Misyak Sarah
Published: December 2024

Background: Federally funded nutrition education programs, such as the Supplemental Nutrition Assistance Program-Education (SNAP-Ed), produce annual reports on program impacts and outcomes. Some reports have traditionally used a “deficit frame,” which potentially stigmatizes participants. On the other hand, asset framing and ethical storytelling practices can empower communities and partners and reduce stigma. The purpose of this project was to determine how the language used in the 2022 Virginia SNAP-Ed annual report for the United States Department of Agriculture (USDA) aligns with ethical storytelling and asset-framing practices. In addition, the purpose was to outline strategies for more empowering reporting practices that rely on asset framing and ethical storytelling practices instead of a deficit frame.
Method: Content coding was used to identify instances of asset- and deficit-based framing. Codes were developed from a toolkit on asset framing and ethical storytelling. The annual report was coded by one researcher and reviewed by a second.
Results: Instances of deficit- and asset-framing and ethical storytelling were low. Only seven instances of stigmatizing language were identified. One was “low-income families,” and the other six were instances where “SNAP-eligible” was used to describe a group of people. Both are examples of presenting challenges as personal characteristics. The majority of the language was neutral and did not stigmatize or empower program participants.
Conclusions: Overall, the report did not frequently utilize deficit framing. However, asset-framing practices were also not explicitly used. The authors propose multiple strategies to develop more empowering reporting practices, including implementing an asset frame to emphasize participants’ contributions and strengths and employing ethical storytelling practices to center community voices.

Published: December 2024

To investigate the impact of PCI on renal function in IHD patients and identify risk factors for CIN development.
Background. Contrast-induced nephropathy (CIN) is a common complication among patients with 
ischemic heart disease (IHD) undergoing percutaneous coronary intervention (PCI). Understanding the pathogenesis, risk factors, and preventive measures of CIN is essential for reducing morbidity and mortality.
Materials and methods. An analysis was conducted on patients with IHD who underwent PCI with contrast media administration. Renal function indicators, including serum creatinine levels and glomerular filtration rate, were assessed pre- and post-procedure. Clinical manifestations, CIN incidence, and associated risk factors were evaluated.
Results.The incidence of CIN varied based on baseline renal function and comorbidities. Key risk factors included elevated baseline serum creatinine, diabetes mellitus, and advanced age. Hydration therapy was effective in reducing the incidence of nephropathy.
Conclusion. PCI increases the risk of CIN in IHD patients, particularly in those with predisposing risk factors. Comprehensive renal function assessment and preventive measures are recommended prior to the procedure to minimize risk.
The Gut-Skin Axis: Unraveling the Interplay between Gut Microbiota and Dermatological Health
Authors:   Idaho College of Osteopathic Medicine, Meridian, ID, USA, Fritts Haily
Published: December 2024

The bidirectional communication between the gut microbiota and the
skin, known as the gut-skin axis, has garnered increasing attention as a
novel paradigm in dermatology. This review provides a comprehensive
overview of recent research elucidating the role of gut dysbiosis in the
pathogenesis of dermatological conditions, including acne, eczema, and
psoriasis. Current evidence suggests that alterations in gut microbial
composition and dysregulated immune responses contribute to systemic
inflammation and skin barrier dysfunction. Moreover, microbial
metabolites and immune mediators produced in the gut can influence
skin homeostasis and inflammatory processes. Future research directions
include investigating microbial-based interventions, such as probiotics,
prebiotics, and fecal microbiota transplantation, for modulating the
gut microbiota and improving dermatological outcomes. Furthermore,
integrated multi-omics approaches and advanced computational
modeling hold promise for unraveling complex interactions within the
gut-skin axis and identifying potential therapeutic targets for personalized
dermatological care.

Learning mathematics through inquiry
Authors: Skovsmose Ole , Säljö Roger
Published: December 2024

The role of inquiry in teaching and learning has been discussed for a long time and by many leading educational philosophers and analysts. The purpose of this article is to analyse the assumptions and some of the outcomes of two interrelated and extensive developmental projects in mathematics teaching and learning in Norway. The projects – referred to as the KUL projects (Knowledge, Instruction, Learning) – aimed at introducing the notion of communities of inquiry as a basis for developing mathematics teaching and learning in participating schools, and as a model for organizing developmental work in cooperation between teachers and researchers. In several respects, it seems as if the projects have been successful in the sense that they were accepted by the teachers (especially at lower levels) as a productive mode of engaging in developmental work. In the article, the interpretation of the concept of inquiry in the projects is scrutinized. It is argued that in order to develop our understanding of inquiry processes, detailed analyses of the nature of inquiry in interactional activities in mathematics learning is necessary. It is also argued that the notion of inquiry adopted by the projects is based on a conception where inquiry is seen as a means of learning mathematics better. An alternative conception is to see inquiry as a means of promoting critical thinking in which understanding of mathematics is at the core of the development of more general reasoning skills that play a central role in a democratic society.
Bilingual students’ mother tongue – a resource for teaching and learning mathematics
Authors: Norén Eva
Published: December 2024

This article presents some of the main results of a bilingual mathematics teaching project, which run in five multicultural schools in Sweden. The main research question was: How do mathematical practices emerge in bilingual mathematics classrooms? In the project bilingual mathematics teachers seemed to promote mathematical learning and engagement in the classroom by using two languages in mathematical discourses. Pupils and teachers communicated mathematically in different ways, and the interplay between mathematics and language often became obvious. Bilingual pupils participating in the project expressed that they were able to learn more and they felt secure with the ways of using languages and learning mathematics. Participating in the project gave many of the pupils’ confidence in their mathematics learning competence.
Homework and minority students in difficulty with learning mathematics – the influence of public discourse
Authors: Lange Troels
Published: December 2024

In this paper, I contrast an immigrant 10 years old girl’s perception of her home support and her mathematics teacher’s rather different perception. I show how the girl tries to align her perception of her home support with middle class Danish family values, and how the public discourse about immigrants apparently frames the teacher’s per- ception of the resources that are available or not available to the girl. The analysis becomes an example of how mathematics teaching and learning are embedded in a wider socio-political field. It suggests that sometimes resources could be available that schools do not see because students are constructed as disadvantaged.
School mathematical discourse in a learning landscape – understanding mathematics education in multicultural settings
Authors: Valero Paola , Meaney Tamsin , Alrø Helle , Fairhall Uenuku , Trinick Tony
Published: December 2024

By bringing our research work together, we are able to discuss the potential of combining the notions of the learning landscape and school mathematical discourse. We do so in a search for concepts and methodological tools to challenge the simplification of issues in regard to mathematics learning in multicultural settings, when adopting restricted perspectives on issues of bilingualism. In the paper we discuss the relationship between the learning landscape and school mathematical discourse. We then use these notions to analyse two case studies in Danish and New Zealand schools. Our conclusion raises possibilities about how these notions can be used when researching mathematics education in multicultural settings.

Denne artikkelen fokuserer på arbeidsformer i matematikk i begynnaropplæringa i grunnskulen, og byggjer på data innsamla gjennom klasseromsobservasjonar over ein treårsperiode (2002–2005). Funna som her blir presenterte viser stor variasjon i arbeidsmåtar, men tradisjonelle arbeidsmåtar har ei dominerande rolle. Lærebøkene styrer svært mykje av aktiviteten og taus oppgåveløysing er den mest typiske arbeidsforma. Temaarbeid utgjer ein betydeleg mindre del av undervisningstida enn det læreplanen føreskriv. Det er lite samarbeid og elevane får i liten grad uttrykke tankane sine i ein sosial samanheng. Elevane får i liten grad hjelp frå lærar til å strukturere kunnskapen og til å sette ny kunnskap inn i ein større samanheng. Det mest oppsiktsvekkjande einskildresultatet er at det vert brukt markert mindre tid til arbeid med matematikkfaget enn det læreplanen legg opp til.
Identities-in-action – exploring the fragility of discourse and identity in learning mathematics
Authors: Stentoft Diana , Valero Paola
Published: December 2024

The notion of identity is often used in mathematics education research in an attempt to link individual and social understandings of mathematical learning. In this paper we review existing research making use of the notion of identity, and we point to some of the strengths and weaknesses in the ways the notion of identity is being constructed. We propose a conceptualization of the notion which points to the fragility and instability of identification processes as embedded into discourse. We contend that a notion of identity formulated from a poststructuralist perspective and emphasising the dialectic relationship between identification and discourse offers interesting possibilities for interpretations of mathematical learning as a fragile process characterised more by discontinuities and disruptions than by continuity and stability. We further argue that a poststructuralist notion of fragile identities in action allows us to bring attention to what is normally considered as ”noise” or ”impossibilities” in our understandings of mathematics education and classroom interaction.
Development of students’ concept images in analysis
Authors: Juter Kristina
Published: December 2024

Students’ pre-knowledge and conceptual development in analysis were investigated at a teacher education program to reveal what pre-knowledge endured and how the students perceived the concepts a year after the course had ended. Questionnaires and interviews were used to collect data. Two students’ results are presented in more detail in the article. The study was cognitively framed with the influence of situated theories to take as many aspects of concept development into account as possible. The students showed numerous connections between concepts, but they were often unable to discern valid links from invalid links. The perceived richness from many connections causes unjustifiably strong self-confidence which prevents further work with the concept. A tool for classification of the students’ connections between concepts resulted from the analysis.
What is quality in a PhD dissertation in mathematics education?
Authors: Niss Mogens
Published: December 2024

The present paper discusses the issue of quality in PhD dissertations in mathematics education on the basis of the author’s reflections, observations and experiences as a supervisor and as an assessor of PhD dissertations in several countries during the last three decades. Thus, the paper represents the personal stances and views of the author and does not claim to be written on behalf of any segment of the community of researchers in mathematics education. Two major components of quality in a PhD dissertation are being dealt with, quality of the underlying research, and quality of the dissertation as a reflective report of this research and its outcomes. Particular attention is being paid to the issue of what should cause a dissertation to be rejected. The paper emphasises, at the end, that because of the multiplicity of research paradigms and philosophies in research in mathematics education there is no royal road to quality in a PhD dissertation. Therefore, the student cannot avoid involving him- or herself in independent in-depth thinking.

Professional development in early mathematics: effects of an intervention based on learning trajectories on teachers’ practices
Authors: Sarama Julie , Clements Douglas H. , Wolfe Christopher B. , Spitler Mary Elaine
Published: December 2024

We evaluated the effects of a research-based model for scaling up educational inter- ventions on teachers’ practices in preschool mathematics. The original participants were from 106 classrooms for 4-year-olds in two distal city districts serving low-resource communities, with 42 schools randomly assigned to one of three groups, of which the two treatment groups were the same throughout preschool (thus, there were 72 treatment classrooms). The intervention, a professional development program based on young children’s mathematical learning trajectories, had a substantial positive effect on teachers’ instructional practices, some of which mediated student outcomes. Teachers also demonstrated sustained levels of fidelity as long as six years after the end of the intervention. Notable is these teachers’ encouragement and support for discussions of mathematics and their use of formative assessment. Finally, teachers taught the curriculum with increasing fidelity over the following six years without support from the project.
Formative assessment in Swedish mathematics classroom practice
Authors: Andersson Catarina , Boström Erika , Palm Torulf
Published: December 2024

Research shows that substantial learning gains are possible through the use of formative assessment. However, little is known about Swedish mathematics teachers’ use of formative assessment, and thus about the possible value of professional development programmes. This study uses teacher interviews and classroom observations to examine the classroom practice of 38 randomly selected primary and secondary school teachers in a mid-sized Swedish municipality. A framework of formative assessment comprising one big idea and five Key strategies structured the analysis. The study identifies characteristics of current formative assessment practices. The results show that the teachers do use a variety of formative assessment activities, but also that there is much room for development towards a more effective formative classroom practice.

The teaching of mathematical problem-solving in Swedish classrooms: a case study of one grade five teacher’s practice
Authors: Pansell Anna , Andrews Paul
Published: December 2024

In this paper we examine the teaching of mathematical problem-solving to grade five students of one well-regarded and experienced Swedish teacher, whom we call Mary. Working within a decentralised curriculum in which problem-solving is centrally placed, Mary is offered little systemic support in her professional decision making with respect to problem-solving instruction. Drawing on Lester’s and Schroeder’s descriptions of teaching for, about and through problem-solving, we draw on multiple sources of data, derived from interviews and videotaped lessons, to examine how Mary’s problem-solving-related teaching is constituted in relation to the weakly-framed curriculum and the unregulated textbooks that on which she draws. The analyses indicate that Mary’s emphases are on teaching for and about problem-solving rather than through, although the ambiguities that can be identified throughout her practice with respect to goals, curricular aims and the means of their achievement can also be identified in the curricular documents from which she draws.
First and second language students’ achievement in mathematical content areas
Authors: Petersson Jöran
Published: December 2024

This study compares Swedish first (n = 2 253) and second language (n = 248) students’ achievement in mathematical content areas specified by the TIMSS-framework. Data on mathematics achievement from three national tests 2007–2009 in school year 9 are used. The present study found that the achievement difference between the mathematical content areas algebra and number was smaller for second language students than for first language students and this result holds with statistical significance (p = 0.016). The same holds for algebra versus data and chance (p = 0.00053). A hypothesis for further research is suggested; that students immigrating in late school years have contributed to the observed result by bringing experiences from other curricula into their new schooling.

Denne artikkelen handler om hvordan egenskaper ved en didaktisk situasjon i matematikk påvirker studenters muligheter til å løse en algebraisk generaliseringsoppgave. Studien er gjennomført innenfor et lærerutdanningsprogram ved en høgskole, og datamaterialet består av matematikkoppgaven og et videoopptak av tre studenters samarbeid for å løse oppgaven. Transkripsjonen av videoopptaket er analysert ved den konstant komparative metoden, der teorien for didaktiske situasjoner i matematikk (TDS) er brukt for å forstå hvilke egenskaper ved den didaktiske situasjonen som begrenser studentenes muligheter for å løse oppgaven. Den observerte didaktiske situasjonen er en ordinær undervisningssituasjon i den forstand at den ikke er et resultat av didaktisk ingeniørvirksomhet basert på TDS. Resultatene fra analysen viser hvordan to faktorer skaper avstand mellom lærerens hensikt med den gitte matematikkoppgaven og studentenes aktivitet knyttet til oppgaven. Den ene faktoren handler om begrepet ”matematisk setning” som studentene tillegger en annen betydning enn den læreren legger til grunn; den andre faktoren handler om lærerens bruk av et generisk eksempel uten at de generelle egenskapene til eksemplet blir diskutert. Studien bidrar til innsikt i sammenhengen mellom et miljø for en adidaktisk situasjon og den matematikkunnskapen som studenter har mulighet for å utvikle i det aktuelle miljøet.
Research as praxis, en route theory/practice teacher-researcher collaboration: a self-study
Authors: Gade Sharada
Published: December 2024

This paper relates to project related instructional interventions, conducted via teacher-researcher collaboration in a Grade Four mathematics classroom. Drawing upon cultural historical activity theory or CHAT perspectives, such conduct exemplifies research as praxis. While CHAT perspectives argue for a theory/practice approach, enabling practitioners to act on their reflexivity and address contradictions found in ongoing practice; research as praxis views practitioner reflexivity as central to pursuing openly ideological work and practising in empirical inquiry what one preaches in theoretical formulations. Such pursuit led to our becoming stakeholders in each other’s professional practice and the conduct of interventions becoming the shared object of both teaching and research. In teacher-researcher collaboration realising expansive learning activity, it was possible to question modernist assumptions which view abstract theory as applicable to any concrete practice and take political action in dialectic with theory.
A review of the impact of formative assessment on student achievement in mathematics
Authors: Palm Torulf , Andersson Catarina , Boström Erika , Vingsle Charlotta
Published: December 2024

Research reviews show that formative assessment has great potential for raising student achievement in general, but there is a need for reviews of formative assessment in individual subjects. This review examines its impact on student achievement in mathematics through an assessment of scientific journal articles published between 2005 and 2014 and indexed in Web of science. Through the use of search terms such as ”formative assessment”, ”assessment for learning” and ”self-regulated learning”, different approaches to formative assessment were included in the review. While varying in approach, they all share the defining characteristic of formative assessment: agents in the classroom collect evidence of student learning and, based on this information, adjust their teaching and/or learning. The results show positive relations between student achievement in mathematics and the ways of doing formative assessment included in the review.
Theorizing the interactive nature of teaching mathematics: contributing to develop contributions as a metaphor for teaching
Authors: Eckert Andreas
Published: December 2024

The teachers’ role in teacher-student interaction in mathematics has received increased attention in recent years. One metaphor used to describe teaching in teacher-student interaction is to describe teaching as a learning process itself, in terms of learning to develop learning. The aim of the present study is to contribute to the conceptualization and understanding of this view of teaching mathematics. This is done by introducing and elaborating on a new conceptual framework, describing teaching as Contributing to Develop Contributions (CDC). The CDC framework is constructed by combining the theory of symbolic interactionism with a complementing metaphor for learning; learning as contribution. The CDC-framework is illustrated in the context of experimentation-based, interactive teaching of probability. The analysis shows how the CDC-framework helps in coming to understand how teachers develop their own contributions to manipulate the negotiation of meaning of mathematics in the classroom and thereby also develops the students’ contributions. In the presented case we can see how CDC particularly helps in giving account of how a teacher develops her way of using symbols and indications and adjust her own interpretations during a whole class discussion where the teacher and students interpret the empirical results of a random generator. In addition, the analysis also illustrates how the framework draws our attention to how a teacher can contribute to the negation of meaning, and so, to students’ opportunities to learn, by making her own interpretations and ways of ascribing meaning to objects transparent to the students in the interaction.
Analysing genomgång: a Swedish mathematics teaching lesson event
Authors: Andrews Paul , Larson Niclas
Published: December 2024

In this paper, drawing on group interviews focused on Swedish upper secondary students’ perspectives on school mathematics, we analyse participants’ use of the noun genomgång. Loosely translated as a ”whole class event during which the teacher goes through something” and for which there is no English equivalent, the word was used by both interviewers and interviewees even when referring to different forms of whole class activity. Analyses identified four broad categories of genomgång based on their form and function. With respect to form, genomgångs were either transmissive or participative. With respect to function they were either instructional or problem solving.
Characterising undergraduate mathematics teaching across settings and countries: an analytical framework
Authors: Mali Angeliki , Petropoulou Georgia
Published: December 2024

This paper explores the characteristics of teaching of a sample of university mathematics teachers in two countries, Greece and Great Britain, and in two settings, lectures and tutorials, seeking to identify a common ground for undergraduate mathematics teaching. Our observations of teaching and our sociocultural perspectives enabled us to develop a framework for a detailed description of the observed teaching. The description reveals categories of teaching actions, and the associated tools teachers use in selecting tasks for their students, providing comprehensive explanations, extending students’ mathematical thinking, or evaluating students’ mathematical meaning. The findings are across settings and countries in the direction of a profound understanding of undergraduate mathematics teaching.

Transformation gennem teater: I Fluks' fænomenologiske fodspor
Authors: Damsgaard Janne Brammer , Jensen Jens Peter , Brinkmann Svend
Published: December 2024

Kunst, for eksempel performanceteater, kan skabe og påvirke dybe følelsesmæssige og kropslige oplevelser. Dette essay giver, baseret på en fænomenologisk og interdisciplinær tilgang, der involverer teater, sygepleje, filosofi og psykologi, indblik i Teater Fluks’ arbejde med temaet demens. Med udgangspunkt i indsigter skabt gennem et dybdegående interview med kunstnerne, argumenteres for, at kunstens værdi ikke kun ligger i den terapeutiske dimension, men også i muligheden for interaktion med dynamikker, der er indlejret i alle mennesker. Disse dynamikker kan bevæges og farvelægges gennem kunsten, hvilket kan skabe forbindelser mellem mennesker. Med de budskaber ønsker vi at udfordre eksisterende logikker i omsorgs- og sundhedsdomæner, der ofte, ret ensidigt, efterspørger dokumentation af kunstens værdi. I den kontekst argumenteres for, at kunsten ikke nødvendigvis kan eller skal måles, men at dens kraft i sin essens består i frisættelse og fremkaldelse af følelsesmæssige og transformerende aflejringer med potentiale for omsorg, sundhed og uddannelse. Med afsæt i dette perspektiv introduceres psykolog og psykoanalytiker Daniel Sterns forskning med fokus på bevægelse, vitalitetsaffekt som indre følelsesstrømme og associative netværk. Dynamikker som kunsten og kunstnere bevidst kan fremme ved at forbinde sansninger og oplevelser. På den baggrund rækker vi afslutningsvis ud efter perspektiver fra grupper som sjældent inkluderes i offentlige meningsudvekslinger, for eksempel mennesker berørt af demens eller social-og sundhedshjælpere. Med reference til jurist og designhistoriker John Holden og filosof Jacques Rancière ønsker vi at kickstarte en demokratisk dialog om kunstens plads i samfundet, dens iboende værdi og potentiale for omsorg.
