    Arrow of time: Metaphorical construals of entropy and the second law of thermodynamics2012In: Science Education, ISSN 0036-8326, E-ISSN 1098-237X, ISSN 1098-237X, Vol. 5, no 96, p. 818-848Article in journal (Refereed)
    Abstract [en]

    Various features of scientific discourse have been characterized in the science education literature, and challenges students face in appropriating these features have been explored. Using the framework of conceptual metaphor, this paper sought to identify explicit and implicit metaphors in pedagogical texts dealing with the concept of entropy and the second law of thermodynamics, an abstract and challenging domain for learners. Three university-level textbooks were analyzed from a conceptual metaphor perspective, and a range of explicit and implicit metaphors were identified. Explicit metaphors identified include entropy as disorder, thermodynamics processes as movements along a path, and energetic exchange as financial transactions among others. Implicit metaphors include application and elaboration of the generic Location Event Structure metaphor, application of the Object Event Structure metaphor, and others. The similarities and differences between explicit and implicit metaphors found in the textbooks are also described. Two key pedagogical implications are discussed: that the selection of explicit instructional metaphors can be guided by consistency with implicit metaphors; and that the range of implicit metaphors found in pedagogical texts implies that a multiple instructional metaphor strategy is warranted. The depth of the phenomenon of conceptual metaphor and its implications for future research are also discussed

    Analogical reasoning in science education: - connections to semantics and scientific modelling in thermodynamics2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Analogical reasoning is a central cognitive ability that is used in our everyday lives, as well as in formal settings, such as in research and teaching. This dissertation concerns how analogies and analogical reasoning, attention to semantics and insight into scientific modelling may be recruited in order to come to terms with challenges in science education, in particular within the field of thermodynamics. In addition, it provides a theoretical framework of how analogy relates to semantics and the practice of scientific modelling, three fields of study which all strive to map correspondences between two different domains. In particular, the dissertation addresses the following research questions: To what degree is analogy involved in connecting different representations of a phenomenon to each other and to the represented phenomenon? How do students’ selfgenerated analogies relate to the practice of scientific modelling?

    The dissertation comprises four published journal articles and a cover story. The first article is a semantic investigation of the word ‘entropy’, the second article is an empirical study of the view on scientific modelling in different traditions of knowledge, and the third and fourth articles are empirical studies of self-generated analogies for thermal phenomena among preservice physics teachers and first-graders, respectively. From a methodological point of view, the empirical studies were conducted in a primarily qualitative tradition, where central lines of reasoning are exemplified by analysis of dialogue excerpts. The two studies on self-generated analogies provided the participants with extensive scaffolding in the form of social interaction among peers, interaction with physical phenomena and discussion of their representations of the phenomena. The theoretical framework is developed in the cover story, which provides a background to the individual studies and reanalyses of the findings.

    A key claim of the dissertation is that any phenomenon can be represented in many different ways, all potentially adequate and useful in different contexts, emphasising different aspects of the phenomenon. Applied to the field of analogical reasoning, it is argued that students can generate several analogies themselves in order to get a richer, complementary view of a phenomenon, as opposed to be provided with a presumed best analogy. As for scientific models, many different representations or models may bring across different aspects of a phenomenon at varying degrees of idealisation and within different traditions of knowledge. Finally, in semantics, one word may correspond to several distinct, yet related, meanings: the phenomenon of polysemy. These three perspectives may provide constructivist approaches to conceptual development in science teaching, in which students are encouraged to connect to and enrich their everyday understanding of encountered concepts and phenomena in dialogue, rather than merely abandoning them for one single, supposedly correct, scientific concept.

    In addition, science education research can come quite far with structural approaches to analysing analogical reasoning and scientific modelling, establishing correspondences between entities in different domains, ultimately striving for isomorphism, perfect matches, but other dimensions, such as the perceptual, embodied nature of our cognition, the pragmatic, contextual circumstances in which any act of reasoning is performed, and the specificities of language, should also be taken into account for a fuller view.

    Abstract [en]

    A challenge in the teaching of entropy is that the word has several different senses, which may provide an obstacle for communication. This study identifies five distinct senses of the word entropy, using the Principled Polysemy approach from the field of linguistics. A semantic network is developed of how the senses are related, using text excerpts from dictionaries, text books and text corpora. Educational challenges such as the existence of several formal senses of entropy and the intermediary position of entropy as disorder along the formal/non-formal scale are presented using a two-Dimensional Semiotic/semantic Analysing Schema (2-D SAS).

    Abstract [en]

    Nineteen informants (n = 19) were asked to study and comment two computer animations of the Otto combustion engine. One animation was non-interactive and realistic in the sense of depicting a physical engine. The other animation was more idealised, interactive and synchronised with a dynamic PV-graph. The informants represented practical and theoretical traditions of knowledge: science students and teachers at upper secondary school level; vocational students and teachers in vehicle mechanics at upper secondary school level, and; MSc and PhD students in vehicle system engineering. The aim was to explore how they interpreted the animations against the background of their different traditions of knowledge and their experience of physical engines and models of engines. A key finding was that the PhD students saw the interactive animation as a familiar and useful model of engines, whereas the vehicle mechanics teachers saw it as a poor representation of reality. A general conclusion was that there is a variety of competent ways to interpret a model, depending on the tradition of knowledge.

    Abstract [en]

    Using self-generated analogies has been proposed as a method in a constructivist tradition for students to learn about a new subject, by use of what they previously know. We report on a group exercise on using self-generated analogies to make sense of two thermodynamic processes, reversible adiabatic expansion and free adiabatic expansion of an ideal gas. The participants (N = 8) were physics preservice teacher students at the fourth year of the teacher education program. A main finding was that work with self-generated analogies tended to be accompanied by the students assuming ownership for their learning, manifested in terms of actions of choice and control and the use of exploratory talk. Consequently, several self-generated analogies were elaborated and developed to a high-order relational structure. However, we also found that with the use of self-generated analogies in science teaching follows the risks of developing idiosyncratic explanations of the encountered phenomena or getting stuck in overly complex comparisons.

    Abstract [sv]

    Självgenererade analogier har förts fram som en metod i en konstruktivistisk tradition för att elever och studenter ska kunna lära sig något nytt genom att relatera till vad de redan vet. Vi redogör här för en gruppövning där självgenererade analogier användes för att förstå två termodynamiska processer: reversibel adiabatisk expansion, respektive fri adiabatisk expansion av en ideal gas. Åtta (N = 8) lärarstudenter på fjärde året av utbildningen med inriktning mot fysik på gymnasiet deltog i studien. Ett viktigt resultat var att vid arbete med självgenererade analogier tenderade studenterna att ta ägandeskap för sitt lärande, vilket tog sig uttryck i handlingar såsom aktiva val, kontroll över processen och explorativ dialog. Som en följd utvecklades flera av de självgenererade analogierna till ett stort strukturellt djup. Samtidigt såg vi att vid skapande av egna analogier löper studenter risken att utveckla egna förklaringar av de studerade fenomenen som inte svarar mot dem inom vetenskapen eller snärja in sig i alltför komplexa jämförelser.

    Abstract [en]

    This exploratory study in a classroom setting investigates first graders (age 78 years, N = 25) ability to perform analogical reasoning and create their own analogies for two irreversible natural phenomena: mixing and heat transfer. We found that the children who contributed actively to a full-class discussion were consistently successful at making analogical comparisons between known objects provided by a researcher and that some of the children could come up with their own analogies for the abstract natural phenomena with which they interacted. The use of full-class and small-group settings, shared laboratory experiences of the phenomena and childrens drawings as different kinds of scaffolding was found to be helpful for the childrens analogical reasoning. As an implication for science education, self-generated analogies are put forward as a potential learning tool within a constructivist approach to education.

    Collaborative and self-generated analogies in science education2013In: Studies in science education, ISSN 0305-7267, E-ISSN 1940-8412, Vol. 49, no 1, p. 35-68Article in journal (Refereed)
    Abstract [en]

    It has long been recognised that analogies may be a useful tool in science education. At the same time, it has been found that there are challenges to using analogies in teaching. For example, students might not identify a suitable analogy, might not recognise how the taught target domain is similar to the source domain to which it is compared, or may fail to realise where the analogy breaks down. The present study offers a review of two trends which reflect the ambition to come to terms with such challenges: self-generated analogies, making use of students’ own analogies in teaching, and analogy generation in collaborative settings, such as in small-group work. Empirical studies show predominately positive results with regard to students’ enjoyment and learning gains, and point to opportunities for formative assessment. The specificities of language in conjunction with analogy and the role of analogies in authentic science classroom discourse are suggested as areas of study that deserve more attention going forward.

    NORDTEK:s Teknikdelegation2012Report (Other academic)
    Abstract [en]

    ‘NORDTEK:s Teknikdelegation’ (NORDTEK’s Technology Delegation) was launched by NORDTEK, a collaboration network for institutes of technology in the Nordic countries, and was conducted with the purpose of investigating initiatives that have been taken in order to strengthen young people’s interest in mathematics, science and technology and the recruitment to engineering educations in the Nordic countries. The focus of the project was on bringing to the fore interesting and successful examples, analyse success factors, and suggest initiatives that would be suitable for spreading to other institutes of technology or to the other Nordic countries. Against a background of a large perceived gap between the number of students that decide to enrol in engineering education and the future demand for engineers in the industry, it is encouraging to see an increase in the enrolment in the Nordic countries the last couple of years. Henceforth, in the short term, a suitable focus might be to attract the “right” students, manage their expectations and work for high retention among the students that actually enrol. Research suggests that many young people are interested in science and technology, as such, but that the corresponding school subjects they have been presented to are perceived as difficult, less interesting and detached from their everyday lives and the society. This is particularly unfortunate with respect to the girls, who require the education to be relevant for them and match their current and future identities. Overall, strengthening of the education programmes that are offered to the students should be given higher priority than information campaigns with the purpose of changing the view of the engineering profession and engineering education.

    Confronting conceptual challenges in thermodynamics by use of self-generated analogies2014In: Science & Education, ISSN 0926-7220, E-ISSN 1573-1901, Vol. 23, no 7, p. 1505-1529Article in journal (Refereed)
    Abstract [en]

    Use of self-generated analogies has been proposed as a method for students to learn about a new subject by reference to what they previously know, in line with a constructivist perspective on learning and a resource perspective on conceptual change. We report on a group exercise on using completion problems in combination with self-generated analogies to make sense of two thermodynamic processes. The participants (N = 8) were preservice physics teacher students at the fourth year of the teacher education program. The students experienced challenges in accounting for the constant entropy in reversible, adiabatic expansion of an ideal gas and the constant temperature in free, adiabatic expansion of an ideal gas. These challenges were found to be grounded in the students’ intuitive understanding of the phenomena. In order to come to terms with the constant entropy in the first process, the students developed idiosyncratic explanations, but these could by properly adjusted given suitable scaffolding. In contrast, the students by themselves managed to make sense of the constant temperature in free expansion, by use of microscopic explanatory models. As a conclusion, self-generated analogies were found to provide a useful approach to identifying challenges to understanding among students, but also for the students to come to terms with these challenges. The results are discussed against a background of different perspectives on the issue of conceptual change in science education.

    Taking advantage of the "Big Mo": Momentum in everyday english and swedish and in physics teaching2015In: Research in science education, ISSN 0157-244X, E-ISSN 1573-1898, Vol. 45, no 3, p. 345-365Article in journal (Refereed)
    Abstract [en]

    Science education research suggests that our everyday intuitions of motion and interaction of physical objects fit well with how physicists use the term “momentum”. Corpus linguistics provides an easily accessible approach to study language in different domains, including everyday language. Analysis of language samples from English text corpora reveals a trend of increasing metaphorical use of “momentum” in non-science domains, and through conceptual metaphor analysis, we show that the use of the word in everyday language, as opposed to for instance “force”, is largely adequate from a physics point of view. In addition, “momentum” has recently been borrowed into Swedish as a metaphor in domains such as sports, politics and finance, with meanings similar to those in physics. As an implication for educational practice, we find support for the suggestion to introduce the term “momentum” to English-speaking pupils at an earlier age than what is typically done in the educational system today, thereby capitalising on their intuitions and experiences of everyday language. For Swedish-speaking pupils, and possibly also relevant to other languages, the parallel between “momentum” and the corresponding physics term in the students’ mother tongue could be made explicit.

    Primary school childrens´s ideas of mixing and heat as expressed in a classroom setting2014In: Journal of Baltic Science Education, ISSN 1648-3898, E-ISSN 2538-7138, Vol. 13, no 5, p. 726-739Article in journal (Refereed)
    Abstract [en]

    This study investigates primary school children’s (7-8 year-old, N = 25) ideas of mixing of marbles and of heat, expressed in small-group predict-observe-explain exercises, and drawings representing the children’s own analogies in a classroom setting. The children were typically found to predict that marbles of two different colours would mix when rocked back and forth on a board. This idea of mixing is slightly more advanced than previously reported in the literature. The children’s ideas of heat included reference to warm objects, their own bodies when exercising, and the process of one warm solid object heating another object in direct contact. In addition, through scaffolding, some of the children expressed a substance view of heat. Finally, the potential and challenges in probing children’s ideas through a combination of data collection techniques in a classroom setting are reflected upon

    Taking on the Heat—a Narrative Account of How Infrared Cameras Invite Instant Inquiry2016In: Research in science education, ISSN 0157-244X, E-ISSN 1573-1898, Vol. 46, no 5, p. 685-713Article in journal (Refereed)
    Abstract [en]

    Integration of technology, social learning and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where students often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can strengthen students’ understanding of thermal phenomena. Grounded in the Swedish physics curriculum and part of a broader research programme on educational uses of IR cameras, we have developed laboratory exercises around a thermal storyline, in conjunction with the teaching of a heat-flow model. We report a narrative analysis of how a group of five fourth-graders, facilitated by a researcher, predicts, observes and explains (POE) how the temperatures change when they pour hot water into a ceramic coffee mug and a thin plastic cup. Four chronological episodes are described and analysed as group interaction unfolded. Results revealed that the students engaged cognitively and emotionally with the POE task and, in particular, held a sustained focus on making observations and offering explanations for the scenarios. A compelling finding was the group’s spontaneous generation of multiple "what-ifs" in relation to thermal phenomena, such as blowing on the water surface, or submerging a pencil into the hot water. This was followed by immediate interrogation with the IR camera, a learning event we label instant inquiry. The students’ expressions largely reflected adoption of the heat-flow model. In conclusion, IR cameras could serve as an access point for even very young students to develop complex thermal concepts.

    Different Senses of Entropy-Implications for Education2010In: ENTROPY, ISSN 1099-4300, Vol. 12, no 3, p. 490-515Article in journal (Refereed)
    Abstract [en]

    A challenge in the teaching of entropy is that the word has several different senses, which may provide an obstacle for communication. This study identifies five distinct senses of the word entropy, using the Principled Polysemy approach from the field of linguistics. A semantic network is developed of how the senses are related, using text excerpts from dictionaries, text books and text corpora. Educational challenges such as the existence of several formal senses of entropy and the intermediary position of entropy as disorder along the formal/non-formal scale are presented using a two-Dimensional Semiotic/semantic Analysing Schema (2-D SAS).

    Perspective on models in theoretical and practical traditions of knowledge: The example of Otto engine animations2012In: International journal of technology and design education, ISSN 0957-7572, E-ISSN 1573-1804, Vol. 22, no 3, p. 311-327Article in journal (Refereed)
    Abstract [en]

    Nineteen informants (n = 19) were asked to study and comment two computer animations of the Otto combustion engine. One animation was non-interactive and realistic in the sense of depicting a physical engine. The other animation was more idealised, interactive and synchronised with a dynamic PV-graph. The informants represented practical and theoretical traditions of knowledge: science students and teachers at upper secondary school level; vocational students and teachers in vehicle mechanics at upper secondary school level, and; MSc and PhD students in vehicle system engineering. The aim was to explore how they interpreted the animations against the background of their different traditions of knowledge and their experience of physical engines and models of engines. A key finding was that the PhD students saw the interactive animation as a familiar and useful model of engines, whereas the vehicle mechanics teachers saw it as a poor representation of reality. A general conclusion was that there is a variety of competent ways to interpret a model, depending on the tradition of knowledge.

    Modeller, analogier och metaforer i naturvetenskapsundervisning2013Collection (editor) (Other academic)
    Abstract [sv]

    Elever kan bara lära sig nya saker genom att bygga på det de redan vet och sina tidigare erfarenheter. Detta är en viktig utgångspunkt i konstruktivismen. Samtidigt är naturvetenskapen ofta abstrakt till sin karaktär. Hur kan vi som lärare skapa miljöer och situationer i naturvetenskapsundervisningen där våra elever ges möjlighet att dra nytta av sina tidigare kunskaper och inne­boende resurser? Ett sätt att åstadkomma detta är att använda sig av modeller, analogier och metaforer i undervisningen.

    I denna antologi presenteras forskning och undervisningsexempel kring hur man kan använda modeller, analogier och metaforer, samt elevers egna representationer i undervisningen i fysik, kemi och biologi.

    Antologin vänder sig främst till blivande och verksamma lärare i ­naturvetenskap med fokus på grundskolans senare år och gymnasiet, samt lärarutbildningen i naturvetenskapliga ämnen och deras didaktik.

    Exploring the Use of Conceptual Metaphors in Solving Problems on Entropy2013In: The Journal of the learning sciences, ISSN 1050-8406, E-ISSN 1532-7809, Vol. 22, no 1, p. 70-120Article in journal (Refereed)
    Abstract [en]

    A growing body of research has examined the experiential grounding of scientific thought and the role of experiential intuitive knowledge in science learning. Meanwhile, research in cognitive linguistics has identified many conceptual metaphors (CMs), metaphorical mappings between abstract concepts and experiential source domains, implicit in everyday and scientific language. However, the contributions of CMs to scientific understanding and reasoning are still not clear. This study explores the roles that CMs play in scientific problem-solving through a detailed analysis of two physical chemistry PhD students solving problems on entropy. We report evidence in support of three claims: a range of CMs are used in problem-solving enabling flexible, experiential construals of abstract scientific concepts; CMs are coordinated with one another and other resources supporting the alignment of qualitative and quantitative reasoning; use of CMs grounds abstract reasoning in a “narrative” discourse incorporating conceptions of paths, agents, and movement. We conclude that CMs should be added to the set of intuitive resources others have suggested contribute to expertise in science. This proposal is consistent with two assumptions: that cognition is embodiment and that internal cognitive structures and processes interact with semiotic systems. The implications of the findings for learning and instruction are discussed.

    Exploiting languages in teaching of entropy2011In: Journal of Baltic Science Education, ISSN 1648-3898, E-ISSN 2538-7138, Vol. 10, no 1, p. 27-35Article in journal (Refereed)
    Abstract [en]

    The words disorder, information, freedom and spreading are used as metaphors and analogies in science teaching to capture the scientific qualitative sense of entropy. In addition, the identification of entropy with the everyday conception of heat has been proposed. While physical sciences are regarded as exact disciplines, in which terms have precise definitions, the words being used in the qualitative interpretation of entropy have many senses. This may provide an obstacle to achieving a scientific understanding of entropy. In this study, the metaphors for entropy and seeing entropy as heat were analysed by use of the different entries for the words in a dictionary. The present paper is a contribution to highlighting the importance of making any metaphors and analogies and their benefits and limitations explicit.

    Pupils' early explorations of thermoimaging to interpret heat and temperature2014In: Journal of Baltic Science Education, ISSN 1648-3898, E-ISSN 2538-7138, Vol. 13, no 1, p. 118-132Article in journal (Refereed)
    Abstract [en]

    In thermodynamics teaching, pupils have been found to confuse temperature and heat, and to conceive touch as an infallible thermometer. This study explored the potential of combining the sense of touch with infrared (IR) thermal imaging on pupils’ understanding of heat and temperature. Eight 7th-grade pupils (12-13 years old) worked in pairs across three laboratory exercises (real-time IR imaging, static IR images, or thermometers) to predict, observe and explain (POE) the temperatures of different objects. An anomaly between perceived ‘coldness’ and measured temperature was induced among the pupils, but they did not manage to resolve this cognitive conflict. The pupils observed the objects getting warmer and increasing in temperature, but did not explain the experiments as involving a heat flow from their bodies to the objects. Successful explanation might require a combination of thermal imaging and the explicit introduction of a simple heat-flow model.
