Exploring Prospective Teachers’ Worldviews and Conceptions of Nature of Science     

Shiang‐Yao Liu  Norman G. Lederman 《International Journal of Science Education》2013,35(10):1281-1307

This study explores the relationship, if any, between an individual’s culturally based worldviews and conceptions of nature of science. In addition, the implications of this relationship (or lack of relationship) for science teaching and learning are discussed. Participants were 54 Taiwanese prospective science teachers. Their conceptions of nature of science and their worldviews specific to humans’ relationship with the natural world were assessed using two open‐ended questionnaires in conjunction with follow‐up interviews. Their understandings of nature of science were classified into informed and naïve categories based upon contemporary views of these constructs and those stressed in international reform documents. An anthropocentric–naturecentric continuum emerged and is used to explain the participants’ views about humans’ relationship with Nature. Participants who recognized the limitations of scientific knowledge, and accept the idea that science involves subjective and cultural components, were more likely to emphasize harmony with Nature. In contrast, participants who possessed narrow views about the scientific enterprise and described science as close to technology and as of materialistic benefit tended to provide an anthropocentric perspective regarding the human–Nature relationships. The findings illustrate the interplay between participants’ sociocultural beliefs and conceptions of nature of science. Concisely, people with different worldviews may have concurrently different views about nature of science. The study suggests the need for incorporating sociocultural perspectives and nature of science in the science curriculum.  相似文献   

What’s in a Name: Differential labelling of plant and animal photographs in two nationally syndicated elementary science textbook series     

Melanie A. Link‐Pérez  Vanessa H. Dollo  Kirk M. Weber  Elisabeth E. Schussler 《International Journal of Science Education》2013,35(9):1227-1242

This study investigated plant and animal photographs in elementary science textbooks to discern whether there were disparities in the number of plant and animal photographs or in how those photographs were labelled. We examined the Life Science sections of two nationally syndicated (USA) textbook series. For each text, we identified the photographs with plant and/or animal content and evaluated them for two features: (1) the subject of the photograph, and (2) the specificity of the label (name) provided. We found that photographs with animal subjects were more numerous than those with plant subjects; they also represented a greater diversity of animals and had a higher instance of repetition than did plant photographs. We also found a significant naming disparity: animal photographs were three times more likely to be provided with a specific label (common name) than were plant photographs. Not only were plant photographs less likely to be provided with a specific name for the plant (e.g. orchid or dandelion), but also they were commonly identified only by the name for a plant part (such as flower or leaf) or life‐form (e.g. tree or shrub). To address the disparity revealed by this study, and to encourage student interest in and knowledge about plants, we recommend that educators go beyond textbooks to expose students to a diversity of named plants, and present plants as distinct organisms rather than as a collection of parts.  相似文献   

Action research: A situated perspective     

Vicky I. Zygouris-Coe  Barbara G. Pace  Cynthia L. Malecki  Regina Weade 《International journal of qualitative studies in education》2013,26(3):399-412

Rigoberta Menchú has become an icon for the struggles of oppressed peoples for justice and self-determination. For many academics and activists around the world, the accusations of lying made against Ms. Menchú by David Stoll brought into sharp focus the politics of "truthmaking" and the absolutist categories of fact and fiction. In this attempt to discredit Ms. Menchú, and through her, the Mayan experience of genocide by the Guatemalan military and its U.S. sponsors, important questions have been raised about how and when Third World women can speak, the conditions under which they will be heard, and the strategies used to silence them. In this paper, the author draws upon some of the lessons of the Rigoberta Menchú case to examine the politics of truth making in Canada in a recent controversy regarding a speech she made criticizing American foreign policy and urging the women's movement to mobilize against America's War on Terrorism. The highly personalized nature of the attacks on the author by political and media elites sought to accomplish a closing down of public space for informed debate about the realities of U.S. foreign policy and to silence dissent. Repeatedly emphasizing her status as an immigrant outsider, this controversy also contributed to the (ongoing) racialization of people of color as a treacherous "enemy" within the nation's geographical borders, against whom "Canadians" had to be mobilized.  相似文献   

Drugs and the Brain: Learning the impact of methamphetamine abuse on the brain through a virtual brain exhibit in the museum     

Meng‐Tzu Cheng  Leonard Annetta  Elizabeth Folta  Shawn Y. Holmes 《International Journal of Science Education》2013,35(2):299-319

Drugs and the Brain: A Serious Game, a prototype museum exhibit, was designed to employ virtual models of the brain into a video game format. It was done to create a fun and engaging way of conveying knowledge and concepts about neuroscience, as well as the impact of methamphetamine abuse on the brain. The purpose of this study is to evaluate this prototype exhibit that promises to educate participants from various age, ethnicity, and gender backgrounds, and to establish a stronger concept of drug abuse prevention among children. A quantitative methodology using the pre‐ and post‐experimental designs was conducted on 175 museum visitors. A series of two‐sample paired t‐tests and subsequent ANOVAs were performed to examine the difference between pre‐ and post‐tests and to determine if there was a difference in the results in age, gender, ethnicity, and race. Results showed that both the understanding and attitudes of the participants toward the impact of methamphetamine abuse on the brain improved significantly (p < 0.01).  相似文献   

Making Science Vivid: Using a historical episodes map     

Chen‐Yung Lin  Jung‐Hui Cheng  Wen‐Hua Chang 《International Journal of Science Education》2013,35(18):2521-2531

Many have argued that the inclusion of the history of science in science teaching might promote an understanding of the nature of science as well as the attitudes toward science. However, its inclusion in science teaching may not have the desired effect due to the limited coverage it receives in textbooks and the limited time available for teaching. A historical episodes map (HEM) is thus developed with four storylines and more than 20 events related to the history of science and is designed to fit in with regular teaching topics. A total of 329 students in Grade 7 were involved in the experimental group and the control group. The control group was taught using the textbook only, while the experimental group was also taught using the textbook plus HEM materials and associated discussion. The intervention of such teaching lasted for a month and a half. The findings reveal that the exposure of students to HEM materials did promote the students’ understanding of the nature of science as well as their attitudes toward science.  相似文献   

US Urban Elementary Teachers’ Knowledge and Practices in Teaching Science to English Language Learners: Results from the first year of a professional development intervention     

Alexandra O. Santau  Walter Secada  Jaime Maerten‐Rivera  Neporcha Cone  Okhee Lee 《International Journal of Science Education》2013,35(15):2007-2032

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5.  相似文献   

The Use of Criteria in Argumentation and the Construction of Environmental Concepts: A university case study     

Araitz Uskola  Gurutze Maguregi  María‐Pilar Jiménez‐Aleixandre 《International Journal of Science Education》2013,35(17):2311-2333

We have analysed the processes of argumentation of three university student groups (A: six students, C: five students, and J: seven students) while making a decision about an environmental problem (selection of a heating system). The discussions took place in three 1½‐hour sessions that were audio‐taped and transcribed. For the analysis of the oral discussions, on the one hand, we have taken into account some of the dimensions characterising the quality of this decision‐making process, including the number and variety of criteria utilised, whether criteria, which did not favour the selected option, were considered and whether priorities were established among criteria, and, on the other hand, the use of environmental concepts such as renewable and sustainability as well as the meanings that were constructed for both concepts. We have determined that the students in this study proposed and utilised, both explicitly and implicitly, a high number and great variety of criteria to support their choices, although they were rarely able to consider contradictory evidence; that is, those that demonstrated disadvantages of the option selected. In terms of the construction of knowledge, we observed that in some groups the proposed task favoured the construction of a concept of sustainability that took the future into consideration and which was utilised as the most important justification in their selection. In terms of the concept of renewable, we found that they did not relate depletion of resources to economic consequences. We discuss the implications for the educational competence development.  相似文献   

Interactive group activity: a socially mediated tool for opening an interpretive space in classroom research     

Barbara Whyte  Deborah Fraser  Viv Aitken  Graham Price 《International journal of qualitative studies in education》2013,26(8):1019-1040

An ongoing challenge in classroom research is to understand children’s perspectives on their learning. While learning is highly individual, it is also significantly social and this raises methodological challenges. An Interactive Group Activity (IGA) is one of several data collection strategies used during the action research phase of the Connecting Curriculum, Connecting Learning project (2010–2011) focusing on arts-based curriculum integration. This article concentrates on the IGA tool as a means of uncovering children’s meaning making following an extended period of learning. Of particular note is the use of an arts pedagogical device to introduce the IGA to children, a device that frames the purpose of the task. In effect, the IGA acts as a group assessment device underlining the socially mediated nature of children’s learning. This article describes how the IGA tool evolved, gives its form and structure, argues for its affordances and suggests possibilities for its wider use.  相似文献   

Power Users and patchworking – An analytical approach to critical studies of young people’s learning with digital media     

Thomas Ryberg  Lone Dirckinck‐Holmfeld 《Educational Media International》2013,50(3):143-156

This paper sets out to problematise generational categories such as “Power Users” or “New Millennium Learners” by discussing these in the light of recent research on youth and information and communication technology. We then suggest analytic and conceptual pathways to engage in more critical and empirically founded studies of young people’s learning in technology and media‐rich settings. Based on a study of a group of young “Power Users”, it is argued that conceptualising and analysing learning as a process of patchworking can enhance our knowledge of young people’s learning in such settings. We argue that the analytical approach gives us ways of critically investigating young people’s learning in technology and media‐rich settings, and study if these are processes of critical, reflexive enquiry where resources are creatively re‐appropriated. With departure in an analytical example, the paper presents the proposed metaphor of understanding learning as a process of patchworking and discusses how we might use this to understand young people’s learning with digital media.

Les “Power Users” et la construction en “patchwork” – Une approche analytique des études critiques portant sur l’apprentissage chez les jeunes avec l’aide des médias numériques.

Le présent article vise à faire ressortir la problématique des catégories de générations, celles par exemple des “Power Users” ou des “Apprenants du Nouveau Millénaire” en les examinant de façon critique à la lumière des recherches récentes sur la jeunesse et les TICE. Nous suggérons ensuite des voies d’approche analytiques et conceptuelles pour nous engager dans des études plus critiques et plus solidement empiriques de l’apprentissage chez les jeunes dans des environnements à fort contenu technologique et médiatique. En nous appuyant sur l’étude d’un groupe de jeunes “Power Users”, on avance l’hypothèse selon laquelle le fait d’analyser et de conceptualiser l’apprentissage comme un processus de construction de patchwork peut améliorer notre connaissance de l’apprentissage chez les jeunes se trouvant dans de tels environnements. Nous avançons l’idée que cette approche analytique nous fournit les moyens d’étudier de façon critique l’apprentissage chez les jeunes se trouvant dans des environnements à fort contenu technologique et médiatique et de déterminer s’il s’agit là de processus de recherche critique et réflexive dans lequel ils se réapproprient les ressources de façon créative. En s’appuyant sur un exemple analytique, cet article présente une proposition, celle d’une métaphore pour comprendre l’apprentissage comme un processus de patchwork et discute de la façon dont nous pourrions l’ utiliser pour comprendre de quelle façon les jeunes apprennent avec les medias numériques.

?Power User“ und ?Patchworking“ – eine analytische Annäherung an kritische Studien über das Lernen junger Leute mit digitalen Medien

Dieser Artikel problematisiert generationspezifische Kategorien wie ?Power Users“ und ?New Millenium Learners“ welche hier vor dem Hintergrund der jüngsten Forschungsergebnisse im Bereich Jugend und Informations‐ und Telekommunikationstechnologie (ITK) diskutiert werden. Darauf aufbauend werden analytische und konzeptionelle Wege vorgeschlagen, wie auf empierischer und auf Fakten basierender Grundlage das Lernen junger Menschen in einem technologie‐ und medienreichen Umfeld studiert werden kann. Eine Gruppe junger ?Power Users“ ist die Grundlage unserer Argumentation, dass Konzeptionalisierung und Analyse des Patchwork Lernprozesses junger Leute unser Verständnis von ihrer Herangehensweise an den Lernprozess verbessern kann. Wir argumentieren, dass die analytische Herangehensweise uns hilft, das Lernen junger Leute im ITK Kontext zu analysieren und wir untersuchen, ob diese Prozesse kritisch und reflexiv sind und dazu beitragen, Ressourcen kreativ zu nutzen. Der Artikel schließt mit einem analytischen Beispiel in dem wir die zuvor diskutierte Metapher – Lernen als einen Patchworkprozess zu verstehen – nutzen, um zu diskutieren wie dieses Verständnis genutzt werden kann, um unser Wissen über das Lernen junger Leute mit digitalen Medien zu erweitern.

Los “Power Users” y la construcción en “patchwork” – Un enfoque analítico sobre los estudios críticos acerca del aprendizaje de los jóvenes con los medios digitales.

El propósito del presente artículo es de hacer resaltar la problemática de las categorías de generaciones, entre ellas los “Power Users” o los “discentes del Nuevo Milenio”, a través de una discusión de esas categorías a la luz de las últimas investigaciones sobre la juventud y las TICs. Sugerimos después algunos caminos analíticos y conceptuales para meterse en estudios con una base más crítica y más fuertemente empírica, del aprendizaje de los jóvenes en entornos con una fuerte dimensión tecnológica y mediatizada. Basandose en el estudio de un grupo de jovenes “Power Users”, se argumenta que el hecho de analizar y conceptualizar el aprendizaje como si fuese un proceso de “patchworking”, puede en realidad realzar nuestro conocimiento de la manera de aprender de los jovenes en entornos de ese tipo. Argumentamos que el enfoque analítico nos ofrece maneras de investigar críticamente el aprendizaje de los jóvenes dentro de entornos fuertemente tecnológicos y mediatizados y de estudiar si se trata de procesos de investigación crítica y reflexiva en los cuales se produce una re‐apropiación creativa de los recursos. Con una salida hacia un ejemplo analítico este artículo presenta la propuesta de una metáfora para entender el aprendizaje como si fuese un proceso de construcción de un “patchwork” con una discusión sobre las posibilidades de uso de esto para entender como los jóvenes aprender con los medios digitales.  相似文献   

International student security: a view from Beijing     

Helen Forbes‐Mewett  Chris Nyland  Sijun Shao 《International Studies in Sociology of Education》2013,23(4):355-373

Security is an integral component of the relationships that shape the lives of students hosted by foreign countries. International student security became a source of contention between nations in 2008 when China's Government charged that Australia was failing to adequately provide for the safety of Chinese students. We discuss Beck's theorisation of the ‘risk society’ and Clements' notion of balancing risk with opportunity. We draw on interviews undertaken in Beijing to highlight the importance of student security and the need for hosts to accord attention to the views of parents as well as students. Our findings reveal that parents play a major role in the study‐location decision, tend to accord security greater weight than do students when location is being debated within the family, utilise a range of strategies to keep students secure and believe host governments and institutions have primary responsibility for student well‐being.  相似文献
