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   

Introduction: Through our eyes and in our own words     

Frances V. Rains  Jo Ann Archibald  Donna Deyhle 《International journal of qualitative studies in education》2013,26(4):337-342

The realities of Indian belief and existence have become so misunderstood and distorted at this point that when a real Indian stands up and speaks the truth at any given moment, he or she is not only unlikely to be believed, but will probably be contradicted and "corrected" by the citation of some non-Indian and totally inaccurate "expert." More, young Indians in universities are now being trained to see themselves and their cultures in terms prescribed by such experts rather than in the traditional terms of the tribal elders ?. In this way, the experts are perfecting a system of self-validation in which all semblance of honesty and accuracy is lost. This is not only a travesty of scholarship, but it is absolutely devastating to Indian societies. (Deloria, as cited in Rose, 1992, p. 404)  相似文献   

Images and stories: through the eyes of at-risk college learners     

Dely Lazarte Elliot  Anne Gillen 《International journal of qualitative studies in education》2013,26(7):912-931

In a study with at-risk Scottish college learners (n?=?81), a participatory action research method called Photovoice was strategically employed. Participant-driven photographs were used to access learners’ intimate thoughts and emotions while photograph-inspired stories were used to understand further their views and experiences. This photo-elicitation method provided access to rich and informative findings and enhanced the overall research process where photographs and narratives encouraged reciprocal validation. The study uncovered four key aspects in supporting at-risk learners: (a) overcoming psychological barriers; (b) addressing physical barriers; (c) providing adequate social support; and (d) assistance through suitable support for learning. This led to three pragmatic results: it (a) raised awareness about the plight of vulnerable learners, (b) afforded them a coordinated voice and (c) brought real benefits to both at-risk and other college learners alike. The implications of the study findings were discussed using the Human Capital Theory.  相似文献   

Ethnocinema and the impossibility of culture     

Anne Harris 《International journal of qualitative studies in education》2013,26(4):546-560

The emerging methodology of ethnocinema fuses techniques from its ethnographic origins with its co-constitutive methods, and invites collaborators to creatively come together for mutual education and cultural transformation. Education as a site of the enactment and “politics of identity construction” continues to confront notions of authenticity/fallacy, hybridity/purity and a media-driven “fictive unity” in the ways we enact and teach culture (Souter, in Hall). Collaborative methods in educational practice, like ethnocinema, suggest that as notions of culture are changing so too must educational practices, both in classrooms and in research contexts. As global mobilities muddy the waters of articulable cultural values and identities, educational practices present an urgent imperative to engage in more dialogic teaching and learning – and more collaboratively generated research – to reduce alienation, generalisation and increase pedagogical border crossing. This article addresses the im/possibility and implications of moving beyond cultural identities in intercultural co-educational dialogue.  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   

Learning about Inheritance in an Out‐of‐School Setting     

Anne Dairianathan 《International Journal of Science Education》2013,35(8):1079-1108

The purpose of this study was to investigate primary students’ learning through participation in an out‐of‐school enrichment programme, held in a science centre, which focused on DNA and genes and whether participation in the programme led to an increased understanding of inheritance as well as promoted interest in the topic. The sample consisted of two groups (245 students in the experimental group and 150 students in the control group) of upper primary students (Grade 5) from six schools in Singapore. Two instruments were developed—a 15‐item multiple‐choice test to measure learning gains and a 17‐item survey form to measure student feedback. Pre‐, post‐, and delayed post‐tests were administered. Results showed statistically significant gains in learning for the experimental group that appeared to be stable as well as high levels of interest stimulated by the programme.  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
