This book was released on 2017-10-20 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial resistance to antibiotics threatens modern healthcare on a global scale. Several actors in society, including the general public, must become more involved if this development is to be countered. The conveyance of relevant information provided through education and media reports is therefore of high concern. Antibiotic resistance evolves through the mechanisms of natural selection; in this way, a sound understanding of these mechanisms underlies explanations of causes and the development of effective risk-reduction measures. In addition to natural selection functioning as an explanatory framework to antibiotic resistance, bacterial resistance as a context seems to possess a number of qualities that make it suitable for teaching natural selection – a subject that has been proven notoriously hard to teach and learn. A recently suggested approach for learning natural selection involves so-called threshold concepts, which encompass abstract and integrative ideas. The threshold concepts associated with natural selection include, among others, the notions of randomness as well as vast spatial and temporal scales. Illustrating complex relationships between concepts on different levels of organization is one, of several, areas where visualizations are efficient. Given the often-imperceptible nature of threshold concepts as well as the fact that natural selection processes occur on different organizational levels, visual accounts of natural selection have many potential benefits for learning. Against this background, the present dissertation explores information conveyed to the public regarding antibiotic resistance and natural selection, as well as investigates how these topics are presented together, by scrutinizing media including news reports, websites, educational textbooks and online videos. The principal method employed in the media studies was content analysis, which was complemented with various other analytical procedures. Moreover, a classroom study was performed, in which novice pupils worked with a series of animations explaining the evolution of antibiotic resistance. Data from individual written assignments, group questions and video-recorded discussions were collected and analyzed to empirically explore the potential of antibiotic resistance as a context for learning about evolution through natural selection. Among the findings are that certain information, that is crucial for the public to know, about antibiotic resistance was conveyed to a low extent through wide-reaching news reporting. Moreover, explanations based on natural selection were rarely included in accounts of antibiotic resistance in any of the examined media. Thus, it is highly likely that a large proportion of the population is never exposed to explanations for resistance development during education or through newspapers. Furthermore, the few examples that were encountered in newspapers or textbooks were hardly ever visualized, but presented only in textual form. With regard to videos purporting to explain natural selection, it was found that a majority lacked accounts of central key concepts. Additionally, explanations of how variation originates on the DNA-level were especially scarce. These and other findings coming from the content analyses are discussed through the lens of scientific literacy and could be used to inform and strengthen teaching and scientific curricula with regards to both antibiotic resistance and evolution. Furthermore, several factors of interest for using antibiotic resistance in the teaching of evolution were identified from the classroom study. These involve, among others, how learners’ perception of threshold concepts such as randomness and levels of organization in space and time are affected by the bacterial context

Available in PDF, EPUB and Kindle. Book excerpt: Antibiotic Resistance: Origins, Evolution, Selection and Spread Chairman: Stuart B. Levy, 1997 Over the last 50 years, the rapid increase in the use of antibiotics, not only in people, but also in animal husbandry and agriculture, has delivered a selection unprecedented in the history of evolution. Consequently, society is facing one of its gravest public health problems-the emergence of infectious bacteria with resistance to many, and in some cases all, available antibiotics. This book brings together a multidisciplinary group of experts to discuss this problem. It begins by examining the origins of resistance and goes on to look at how the use of antibiotics in human medicine and farming/agriculture has selected for resistant bacteria. Separate chapters describe the evolution of resistance determinants and how these are spread both within and between bacterial species. Finally, the book contains discussions on strategies for countering the threat of antibiotic resistance. A major re-thinking of our approach to the treatment of infectious diseases is proposed-that antibiotic resistance should be seen as a problem created by the disruption of normal microbial ecology. To restore efficacy to earlier antibiotics, and to maintain the success of new antibiotics that are introduced, we need to use these drugs in a way that ensures an ecological balance that favours the predominance of susceptible bacteria.
Download or read book Encountering Evolution written by Johanna Frejd and published by Linköping University Electronic Press. This book was released on 2019-08-21 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores preschool class children’s meaning making processes when they encounter evolution. By adopting social semiotic and sociocultural perspectives on meaning making, three group-based tasks were designed. Video data from the activities were analysed using a multimodal approach. The analysis focuses on how the communicated science content affects the science focus of the tasks, how different materials function as semiotic resources and influence meaning making, and interactive aspects of doing science in the meaning-making processes. The findings reveal that, by using the provided materials and their previous experiences, the children argue for different reasons for animal diversity and evolution. Throughout the tasks, a child-centric view of life emerged in a salient manner. This means that, apart from the science focus, the children also emphasise other aspects that they find important. The child-centric perspective is suggested to be a strength that enables children to engage in science activities. The results show that the provided materials had three functions. Children use materials as resources providing meaning. This means that the children draw on the meaning potential of the materials, a process that is influenced by their previous experiences. Moreover, in interaction with peers, the materials also serve as communicative and argumentative tools. Thus, access to materials influences the children’s meaning making and enables them to discuss evolution and “do science”. The findings also reveal an intimate relationship between task context and interaction. More scripted tasks convey more child–adult interaction (scaffolding) while less scripted tasks, during which children build on previous experiences instead of communicated science content, stimulates child–child interaction (mutual collaboration). In scaffolding interactions, a greater emphasis is placed on the science topic of the task due to guidance from the adult. Consequently, meanings made by children in more scripted tasks are more likely to be “scientifically correct”. However, if the teacher or the adult steps back and allows the children to engage in mutual collaboration, they engage in multiple ways of doing science through evaluating, observing, describing and comparing. Overall, the research reported in this thesis suggests that task contexts and materials have a great impact on children’s meaning making and how science is done. Den här avhandlingen utforskar förskolebarns meningsskapandeprocesser kring evolution. Tre gruppbaserade aktiviteter har designats. Videodata har analyserats utifrån ett multimodalt perspektiv på kommunikation. Analysen fokuserar på hur kommunicerade naturvetenskapliga beskrivningar av evolution påverkar aktiviteternas naturvetenskapliga fokus, materials funktion som semiotiska resurser och påverkan på meningsskapande och interaktiva aspekter av att göra naturvetenskap. Avhandlingens resultat visar att barnen, genom att använda material och sina tidigare erfarenheter, för olika resonemang kring varför djur utvecklas och blir olika. Genomgående har barnens syn på världen en betydande roll för meningsskapandeprocessen. Det betyder att barnen, förutom att fokusera på det naturvetenskapliga innehållet i aktiviteterna, också lägger stor vikt vid andra aspekter som är viktiga för dem. Det barncentrerade perspektivet förslås vara en styrka som möjliggör för barn att delta i och engageras av naturvetenskapliga aktiviteter. De material som barnen har tillgång till de i de olika aktiviteterna har tre funktioner. Barnen använder material som meningsgivande resurser, vilket betyder att barnen använder materialens meningspotential. Denna process påverkas av barnens tidigare erfarenheter. Vidare används materialen som kommunikativa- och argumentativa redskap i interaktion med andra. Tillgången till material påverkar således barnens meningsskapande och möjliggör att de kan diskutera evolution påverkar barnens naturvetenskapliga handlande. Avhandlingens resultat visar på en nära relation mellan uppgifters kontext och interaktion. Mer styrda aktiviteter medför mer interaktion mellan barn och vuxna (scaffolding). Mindre styrda aktiviteter, där barnen bygger på sina tidigare erfarenheter, stimulerar istället interaktion mellan barnen (mutual collaboration). Som ett resultat av den vuxnes agerande, läggs det större vikt vid det naturvetenskapliga innehållet (evolution) i scaffolding-interaktioner. Följaktligen är de meningar som skapas i mer styrda aktiviteter mer i linje med naturvetenskapliga förklaringar till evolution. Samtidigt finns det ett samband mellan att den vuxne kliver åt sidan och att barnen kliver fram och gör naturvetenskapliga handlingar som att utvärdera, observera, beskriva och jämföra. Sammanfattningsvis visar den här avhandlingen att uppgifters kontext och material har stor påverkan på barns meningsskapande och hur de gör naturvetenskap.

Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. The history of evolution comprises several scales of magnitude, some of which are far from direct human experience and therefore difficult to understand. One way of addressing this issue is to use dynamic visualizations that represent time, for example, to facilitate teaching and learning about evolution. This thesis investigates how students’ comprehension of evolution and evolutionary time can be facilitated by visualizations in educational settings. Two different dynamic visualizations were investigated. In paper I different temporal versions of a spatio-temporal animation depicting hominin evolution were explored. The temporal information was expressed as one or several timelines along which an animated cursor moved, indicating the rate of time. Two variables, the number of timelines with different scales, and the mode of the default animated time rate (either constant throughout the animation or decreasing as the animation progressed), were combined to give four different time representations. The temporal aspects investigated were undergraduate students' ability to find events at specific times, comprehend order, comprehend concurrent events, comprehend the length of time intervals, and their ability to compare the lengths of time intervals. In paper II, perceptions and comprehension of temporal aspects in an interactive, multi-touch tabletop application, DeepTree, were investigated. This application depicts the tree of life. The focus was on the interactive aspects, especially how the zooming feature was perceived, but also on any misinterpretations associated with the interaction. The same temporal aspects listed for paper I were also implicitly investigated. The findings indicate that handling the problem of large differences in scale by altering the rate of time in the visualization can facilitate perception of certain temporal aspects while, at the same time, can hinder a correct comprehension of other temporal aspects. Findings concerning DeepTree indicate that the level of interactions varies among users, and that the zooming feature is perceived in two ways, either as a movement in time or as a movement in the metaphorical tree. Several misinterpretations were observed, for example the assumption that the zooming time in the tree corresponds to real time, that there is an implicit coherent timeline along the y-axis of the tree, and that more nodes along a branch corresponds to a longer time. The research reported in this thesis supports the claim that careful choice, and informed use of visualizations matters, and that different visualizations are best suited for different educational purposes För att kunna förstå och ta ställning till utmaningar i form av exempelvis klimatförändringar, förlust av biodiversitet och antibiotikaresistens krävs kunskap om evolution. För att förstå evolution är det i sin tur viktigt att inse betydelsen av de tidsskalor som evolutionära processer omfattar. Detta utgör inte sällan ett problem vid undervisning om evolution eftersom det rör sig om tidsskalor som sträcker sig långt bortom vad vi själva kan erfara. Tidsskalor ingår i en grupp av begrepp som kallas tröskelbegrepp. Tröskelbegrepp utmärks av att de är svåra att ta till sig, men när väl förståelse uppnås så innebär det en radikal och permanent förändring av hur ett ämnesinnehåll, exempelvis evolution, betraktas. Av den anledningen är de också ”enkelriktade” i meningen att den nya förståelsen är bestående Ett sätt att bemöta problemen med att förstå tidsskalor av varierande storlekar är att använda dynamiska visualiseringar. Denna avhandling handlar just om hur elevers förståelse av evolution med avseende på tiden kan underlättas genom visualiseringar i undervisning. Avhandlingen baseras på två studier som var och en belyser evolutionär tid på olika sätt beträffande såväl innehåll som form. I den första studien undersöktes hur olika varianter av en tidsrepresentation i form av animerade tidslinjer påverkade 144 studenters förståelse av olika tidsaspekter. Representationen av tid hade två variabler, nämligen antal tidslinjer (en tidslinje respektive 3 tidslinjer med olika skalor) och hastighet för animationen av tidsförloppet (konstant hastighet respektive avtagande hastighet när animationen närmade sig nutid). De två variablerna kombinerades för att ge fyra olika varianter av tidsrepresentation. I studien jämfördes varianterna genom att undersöka studenters förmåga kring olika tidsaspekter; hitta händelser vid specifika tider, uppfatta ordning på händelser, uppfatta samtidiga händelser, uppfatta längden på ett tidsintervall och jämföra längden av två tidsintervall. I den andra studien undersöktes uppfattningar och förståelse av tidsmässiga aspekter hos 10 gymnasieelever med utgångspunkt från det interaktiva multi-touch-bordet ”DeepTree”. Det är en interaktiv visualisering av livets träd, det vill säga de fylogenetiska sambanden mellan organismer på jorden. I denna studie fokuserades de interaktiva aspekterna av visualiseringen, särskilt kring hur zoomfunktionen uppfattades av elever men också vilka missuppfattningar som var kopplade till interaktioner. Även tidsaspekterna från den första studien undersöktes. Resultaten från den första studien visar att det under vissa omständigheter kan vara en fördel att variera det animerade tidsflödet, till exempel genom att hastigheten på tidsflödet i animationen avtar under en speciellt händelserik period som behöver granskas noggrannare. Under andra omständigheter kan det däremot vara olämpligt att variera hastigheten för den animerade tiden eftersom det försvårar bedömningen av storleken på, och jämförelsen av, tidsintervall. Det är alltså viktigt att lärare är medvetna om vilken, eller vilka, tidsaspekter som är centrala i den specifika lärandesituationen. Resultaten från den andra studien visar två olika sätt att uppfatta zoomfunktionen när den används i applikationen DeepTree; antingen som en rörelse i tid eller som en rörelse i det metaforiska trädet. Flera missuppfattningar av interaktionen observerades hos eleverna. Till exempel tolkade en del elever den tid det tog att zooma i trädet som att det motsvarade hur lång tid som förflöt mellan olika evolutionära händelser. Ett antal elever verkade anta att det finns en implicit linjär tidslinje längs y-axeln på trädet, och att ju fler grendelningar som fanns längs en gren desto längre tid motsvarade grenen. Generellt är de flesta tidsaspekter svåra att uppfatta för användare av DeepTree. Evolutionära träd av denna typ är dock främst gjorda för att illustrera släktskapsförhållanden, men de tidsmässiga aspekterna skulle kunna förbättras. Applikationer av den typ som DeepTree utgör har potential att erbjuda goda möjligheter till lärande även beträffande evolutionär tid men hänsyn behöver då tas just till hur tidsaspekter beskrivs.
Download or read book Coteaching chemical bonding with Upper secondary senior students written by Felix Schultze and published by Linköping University Electronic Press. This book was released on 2018-11-22 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to investigate how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers while teaching chemical bonding in a grade 10 Upper secondary class. The study has been conducted from a sociocultural perspective, especially Vygotsky’s zone of proximal development (ZPD) (Vygotsky, 1978). Other theoretical concepts and models that has framed this study are Shulman´s Pedagogical content knowledge (PCK) and Pedagogical reasoning and action model (Shulman, 1986, 1987). When analysing the data, Magnusson, Krajcik, and Borko´s (1999) model of PCK and the 2017 Refined consensus model of PCK (Carlson, Daehler, et al., in press) was used. Empirical data was collected by video- and audio recorded lessons, coreflection sessions, coplanning sessions and interviews. During 10 weeks, about 28 hours of video and audio recordings was collected. Selected parts of the material were transcribed and analysed in order to answer two questions: (1) How can chemistry teachers refine their PCK when coteaching together with senior students in an Upper secondary science class? (2) How do Upper secondary senior student coteachers´ conceptual knowledge of representations and chemical bonding shape a teacher’s foundation of personal PCK (pPCK) when teaching chemical bonding in an Upper secondary science class? The results relating to research question one indicates that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. The coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students’ frames of references. The experienced chemistry teacher improved her understanding of students´ thinking about themselves as learners of chemical bonding. Regarding the second research question, the findings showed that the creative process of reconstructing concepts of chemical bonding in the coplanning sessions meant that these were a useful tool for developing new teaching strategies and to further develop representations such as drama to illustrate chemical bonding. Together, the teacher and student coteachers, constructed a new representation that better illustrated polar covalent bonding. Taken together, these results provide important insights into how the chemistry teacher´s pPCK was refined and how the coteachers contributed to improve instructional strategies.
Download or read book Time Progress Growth and Technology written by Filipe Duarte Santos and published by Springer Nature. This book was released on 2020-09-18 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the current challenges of sustainable development, including its social, economic and environmental components. The author argues that we need to develop a new concept of time based on inter-generational solidarity, which focuses both on the long- and the short term. The evolution of man's notions of time are analyzed from prehistory to modern times, showing how these concepts shape our worldviews, our ecological paradigms and our equilibrium with our planet. Practical approaches to dealing with the major medium- and long term sustainability challenges of the 21st century are presented and discussed. This is a thought provoking and timely book that addresses the main global socioeconomic and environmental challenges facing the current and future generations, using science-based analysis and perspectives. It presents an historical narrative of the advent of progress, economic growth and technology, and discusses the structural changes needed to co-create sustainable pathways. It provides hope for our future on Earth, mankind’s common home. António Guterres, Secretary-General of the United Nations This is an amazing, almost mind-boggling book. The author takes a look at the true whole, i.e., the development of the human enterprise since its very beginning. This enterprise is evidently a possibility under the boundary conditions of cosmological dynamics and natural evolution, but evidently also a highly improbable one. It is all but a miracle that the Earth system in its present form exists and happens to support a technical civilization. Will this civilization last long, will it transform itself into something even more exceptional, or will it perish in disgrace? Santos dares to address these grandest of all questions, equipped with a unique transdisciplinary wisdom drawing on physics, cybernetics, geology, biology, economics, anthropology, history, and philosophy. And he dares to dive into the deepest abysses of thinking, where categorial monsters like time and progress lurk. Thereby, he takes us on fascinating journey, during which we perceive and grasp things we have never seen and understood before. One of the best essays I have ever read.

Download or read book Microbial Evolution written by Howard Ochman and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria have been the dominant forms of life on Earth for the past 3.5 billion years. They rapidly evolve, constantly changing their genetic architecture through horizontal DNA transfer and other mechanisms. Consequently, it can be difficult to define individual species and determine how they are related. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines how bacteria and other microbes evolve, focusing on insights from genomics-based studies. Contributors discuss the origins of new microbial populations, the evolutionary and ecological mechanisms that keep species separate once they have diverged, and the challenges of constructing phylogenetic trees that accurately reflect their relationships. They describe the organization of microbial genomes, the various mutations that occur, including the birth of new genes de novo and by duplication, and how natural selection acts on those changes. The role of horizontal gene transfer as a strong driver of microbial evolution is emphasized throughout. The authors also explore the geologic evidence for early microbial evolution and describe the use of microbial evolution experiments to examine phenomena like natural selection. This volume will thus be essential reading for all microbial ecologists, population geneticists, and evolutionary biologists.

Download or read book Recent Advances in Science and Technology Education Ranging from Modern Pedagogies to Neuroeducation and Assessment written by Zacharoula Smyrnaiou and published by Cambridge Scholars Publishing. This book was released on 2016-03-08 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science and technology education research, influenced by inquiry-based thinking, not only concentrates on the teaching of scientific concepts and addressing any misconceptions that learners may hold, but also emphasizes the ways in which students learn, and seeks avenues to achieve better learning through creativity. New developments in science and technology education rely on a wide variety of methods, borrowed from various fields of science, such as computer science, cognitive science, sociology and neurosciences. This book presents papers from the first international conference on “New Developments in Science and Technology Education” that was structured around seven main thematic axes: namely modern pedagogies in science and technology education; new technologies in science and technology education; assessment in science and technology education; teaching and learning in the light of inquiry learning methods; neuroscience and science education; conceptual understanding and conceptual change in science; and interest, attitude and motivation in science. It explores the beneficial impact of pedagogically updated practices and approaches in the teaching of science concepts, and elaborates on future challenges and emerging issues that concern science and technology education. By pointing out new research directions, the volume will inform educational practices and bridge the gap between research and practice, providing new information, ideas and perspectives. It will also promote discussions and networking among scientists and stakeholders from worldwide scientific fields, such as researchers, professors, students, and companies developing educational software.

Download or read book Why Evolution is True written by Jerry A. Coyne and published by OUP Oxford. This book was released on 2010-01-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.
