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.

This book was released on 2015-03-26. Encountering ETI available in PDF, EPUB and Kindle. 'Encountering ETI' weaves together scientific knowledge and spiritual faith in a cosmic context. It explores consequences of Contact between terrestrial intelligent life (TI) and extraterrestrial intelligent life (ETI). Humans will face cosmic displacement if there are other complex, technologically advanced intelligent beings in the universe; our economic structures and religious beliefs might need substantial revision. On Earth or in space, humans could encounter benevolent ETI (solicitous ofour striving for maturity as a species) or malevolent ETI (seeking our land and goods to benefit themselves, claiming that their 'superior civilization' gives them the right) - or meet both types of species. Earth Encounters of the Third Kind described by witnesses (including Native American elders) suggest that both may have arrived already: some have been accused of shutting down US and USSR ICBM missiles to promote peace; others of mutilating cattle or abducting people, perhaps to acquire physiological data on biota for scientific study or for other, unknown purposes. Scifi movies such as Avatar and novels like The Martian Chronicles describe humans as malevolent ETI aliens: we do to others what we fear others will do to us. A shared and evolving spiritual materiality could enable humanity to overcome cosmic displacement, and guide TI and ETI in a common quest for meaning and wellbeing on cosmic common ground.

What if the biblical creation account is true, with the origins of Adam and Eve taking place alongside evolution? Building on well-established but overlooked science, S. Joshua Swamidass explains how it's possible for Adam and Eve to be rightly identified as the ancestors of everyone, opening up new possibilities for understanding Adam and Eve consistent both with current scientific consensus and with traditional readings of Scripture.

Close Encounters with Humankind: A Paleoanthropologist Investigates Our Evolving Species available in PDF, EPUB and Kindle. “Deftly weaving together science and personal observation, Lee proves an engaging, authoritative guide… of the human condition.” —Kate Wong, editor at Scientific American What can fossilized teeth tell us about our ancient ancestors’ life expectancy? Did farming play a problematic role in the history of human evolution? And what do we have in common with Neanderthals? In this captivating bestseller, Close Encounters with Humankind, paleoanthropologist Sang-Hee Lee explores our greatest evolutionary questions from new and unexpected angles. Through a series of entertaining, bite-sized chapters that combine anthropological insight with cutting-edge science, we gain fresh perspectives into our first hominin ancestors and ways to challenge perceptions about the traditional progression of evolution. With Lee as our guide, we discover that we indeed have always been a species of continuous change.
