The development of a framework for coding argumentations schemes in the transcripts of classroom dialogical deliberations on controversial, socioscientific topics is described. Arriving at a coding framework involved resolving a number of complex issues and challenges that are discussed in order to create practical remedies. The description of the development process is based on audio recordings and written exchanges between the authors as they attempted to resolve differences in the interpretation and application of argumentation schemes . These deliberations address theoretical (...) and practical concerns for adapting notions of argumentation schemes to the practical context of analyzing authentic classroom interactions. The framework was developed to accommodate research and curriculum development in school science education. A practical framework for analyzing argumentation in authentic classroom contexts is proposed and implications for science education and argumentation theory are raised. (shrink)

There has been little investigation to date of the way metacognition is involved in conceptual change. It has been recognised that analytic metacognition is important to the way older children acquire more sophisticated scientific and mathematical concepts at school. But there has been barely any examination of the role of metacognition in earlier stages of concept acquisition, at the ages that have been the major focus of the developmental psychology of concepts. The growing evidence that even young children have a (...) capacity for procedural metacognition raises the question of whether and how these abilities are involved in conceptual development. More specifically, are there developmental changes in metacognitive abilities that have a wholescale effect on the way children acquire new concepts and replace existing concepts? We show that there is already evidence of at least one plausible example of such a link and argue that these connections deserve to be investigated systematically. (shrink)

Using an analogy in science and everyday life is a double-edged sword because they are accompanied by alternative ideas, in addition to scientific concepts. Schools and public education explain global warming by making a common analogy between this phenomenon and greenhouse effects. Unfortunately, this analogy sometimes produces various incorrect explanatory mental models. To construct a correct understanding of global warming, it is necessary: first, to investigate the attributes of analogical reasoning; second, to understand these features by restructuring the greenhouse analogy; (...) and third, to explore the problems and benefits of the greenhouse analogy. The characteristics of relations, rather than objects, must be mapped according to the principle of systematicity, but the public tends to preserve the attributes of the base domain, which is mapped relatively easily. In conclusion, certain facets of the prevailing greenhouse analogy cause a distorted public view of climate change. We must use the greenhouse analogy and yet simultaneously emphasize the relations and attributes highlighted and hidden in the analogy during evaluation. (shrink)

Many scholars often use the terms “metaphors,” “analogies,” and “models” interchangeably and inadvertently overlook the uniqueness of each word. According to recent cognitive studies, the three terms involve distinct cognitive processes using features from a familiar concept and applying them to an abstract, complicated concept. In the field of science and religion, there have been various objects or ideas used as metaphors, analogies, or models to describe the science–religion relationship. Although these heuristic tools provided some understanding of the complex interaction, (...) they failed to address the broad nature of science and religion as well as the multifarious relationship between the two in a sociocultural context. Unlike the previous candidates, the concept of language, including the notions of linguistic worldview, linguistic identity, dialects, power, and bilingualism, offers a unique and comprehensive window through which science, religion, and the relationship between the two are seen with clarity.

Model-based learning has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, (...) I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students’ mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students’ mental representations of models in terms of evolving relational structures in greater detail than previously done.

Entropy is often introduced to students through the use of the disorder metaphor. However, many weaknesses and limitations of this metaphor have been identified, and it has therefore been argued that it is more harmful than useful in teaching. For instance, under the influence of the disorder metaphor, students tend to focus on spatial configuration with regard to entropy but disregard the role of energy, which may lead their intuition astray in problem solving. Albeit so, a review of research of (...) students’ ideas about entropy in relation to the disorder metaphor shows that students can use the metaphor in developing a more nuanced, complex view of the concept, by connecting entropy as disorder to other concepts such as microstates and spreading. The disorder metaphor—in combination with other explanatory approaches—can be used as a resource for learning, in giving students an early flavour of what entropy means, so long as we acknowledge its limitations; we can put this “bad” metaphor to good use in teaching.

Work on analogy has been done from a number of disciplinary perspectives throughout the history of Western thought. This work is a multidisciplinary guide to theorizing about analogy. It contains 1,406 references, primarily to journal articles and monographs, and primarily to English language material. classical through to contemporary sources are included. The work is classified into eight different sections (with a number of subsections). A brief introduction to each section is provided. Keywords and key expressions of importance to research on (...) analogy are discussed in the introductory material. Electronic resources for conducting research on analogy are listed as well.

We believe that physics education has to meet today’s requirement for a qualitative approach to Quantum Mechanics (QM) worldview. An effective answer to the corresponding instructional problem might allow the basic ideas of QM to be accessed atan early stage of physics education. This paper presents part of a project that aims at introducing a sufficient, simple, and relevant teaching approach towards QM into in-/preservice teacher education, i.e., at providing teachers with the indispensable scientific knowledge and epistemological base needed for (...) a reform of science education along the aforementioned line. The investigation of teacher–learners’ (t-ls’) initial knowledge indicated that their main misconceptions appear to be the result of their pre-/in university traditional instruction, which causes the overlapping/mix-up of the conceptual frameworks of Classical Physics (CP) and QM. Assuming that these misconceptions form by nature epistemological obstacles to the acquisition of QM knowledge, the educational strategy proposed here aims at leading t-ls to form a conceptual structure that includes CP and QM as two totally independent conceptual systems. Accepting, furthermore, that the complete distinction of these systems demands a radical reconstruction of t-ls’ initial knowledge, we present here an instructional model that bases the required reconstruction on the juxtaposition of two models that constitute the signal point of twentieth century’s “paradigm shift”: (a) Bohr’s semiclassical atom model, and (b) the model of the atom accepted by modern physics theory.

This thesis considers the role of aesthetic meaning-making in elementary school science learning. Children’s aesthetic experiences are traced through their use of aesthetic judgements, spontaneous metaphors and art activities. The thesis is based on four empirical studies: the first two examining children’s language use, i.e. the role of aesthetic judgements and the significance of spontaneous metaphors while learning science and the latter two dealing with how art activities mediate what elementary school children learn in science and what a variety of (...) art activities with different purposes afford elementary school children to learn in science. The theoretical stance emanates from pragmatist theories and includes Dewey’s definition of an aesthetic experience, Wittgenstein’s later work on language-games, and socio-cultural perspectives. The analytic approach used is a practical epistemology analysis developed by Wickman and Östman. The empirical data consists of audio- and video recordings of elementary school children’s (aged 6–10 years) discussions in pairs or small groups during science lessons and photographs of children’s pictures, sculptures and poems from a total of 14 different elementary school classes. The main findings of the empirical studies show how aesthetic meaning-making is continuous with elementary school children’s scientific learning. The thesis shows how elementary school children’s aesthetic experiences are related to whole activities and are crucial for the direction that learning takes. Aesthetic experience is important in terms of how and what elementary school children learn aesthetically and normatively in science class, which has consequences for cognitive learning, the possibility of participating in science class and learning the genre of science. Moreover, it can be seen how children’s prior experiences are recurrently reconstructed and transformed through imaginative processes. (shrink)

Neste trabalho, avaliamos as implicações que o debate filosófico acerca das explicações em termos de função e objetivo podem ter no contexto educacional, particularmente no ensino e aprendizagem de biologia. Para alcançar este objetivo, investigamos como três obras didáticas de biologia do Brasil utilizam a linguagem teleológica na formulação de explicações para os assuntos que são objeto de estudo dessa ciência. Na análise das obras, exploramos os enunciados teleológicos e funcionais a partir de dois projetos explanatórios discutidos na filosofia da (...) biologia contemporânea, a saber: (i) etiológico, que fornece uma abordagem essencialmente histórica de explicação biológica; e (ii) organizacional, que orienta o estudo acerca das capacidades de sistemas complexos mediante o apelo às funções de seus componentes, ou seja, a contribuição das partes para a realização de uma capacidade global. Nossos resultados mostram que poucas explicações podem ser qualificadas como etiológicas, em razão de que os autores preterem a discussão de temas segundo um tratamento evolutivo. Associado a esse resultado, a maioria dos enunciados foi localizada no contexto do projeto organizacional de explicação científica. Na análise das explicações, destacamos os principais problemas que elas apresentam, como a falta de clareza na identificação do explanandum e explanans, situação que pode prejudicar a compreensão dos assuntos pelos estudantes. Por fim, colocamos que a recontextualização das duas abordagens centrais sobre as explicações funcionais na filosofia da biologia, a perspectiva etiológica e a organizacional, podem fornecer um embasamento epistemológico consistente para as explicações biológicas no ensino médio.
