Parent involvement: perceptions of recent immigrant parents in a suburban school district,Minnesota     

Bu-Hyun Nam 《Educational studies》2014,40(3):310-329

The study aimed to examine the perceptions of immigrant parents regarding their school’s efforts to encourage three types of parent involvement: Parenting, Communicating, and Learning at Home. The sample includes 106 immigrant parents with children who were enrolled in English Language Learners programmes at 10 schools in a suburban school district in Minnesota, USA. The results showed that depending on their ethnicities, the children’s school levels and the father’s educational level, the perceptions of the parents were significantly different in terms of the “Parenting” and “Learning at Home” involvement types. Mother’s educational level was significantly correlated to the languages used at home and to their children’s academic achievement in English. Results indicated that schools should consider ethnic backgrounds and educational levels of parents, and languages used at home to instil as collaborations between immigrant parents and schools.  相似文献

Social Influences on Terrestrial and Satellite Mobile-TV Adoption in Korea: Affiliation,Positive Self-Image,and Perceived Popularity     

Kyounghee Hazel Kwon  Bum Soo Chon 《媒体管理杂志》2013,15(2):49-60

Mobile TV is a representative product of media convergence. In South Korea, the diffusion of mobile TV has been in high gear, which provides an exemplary case study of mobile-TV adoption. The study examines the relation between the social influence, adopters' individual factors, and the adoption of the 2 different forms of mobile TV: terrestrial and satellite. Factor analysis identified 3 dimensions of social influences, defined respectively as “affiliation,” “positive self-display,” and “perceived popularity.” Results suggest that these 3 social influences differ in degree in relation to the adopters' demographic characteristics and innovativeness. Adoption of terrestrial or satellite mobile TV was predicted by social influence and, in particular, driven by the motivation to maintain a positive self-image. Because of the implications this may have on media management, the article calls for future research on the social construction of new media technology use to assess how individuals become susceptible to social influences and how social influences affect the diffusion of the technology.  相似文献   

The Net Effect     

Siho Nam 《广播与电子媒介杂志》2013,57(2):260-261

This study introduces the term "travelers" to describe programs that move from one broadcast network to another. Travelers represent a form of television recycling common to the television industry, which has used over three times as many travelers as spin-offs. This article examines and accounts for the history and use of travelers over a fifty-year period: their initial popularity with networks and sponsors in the 1950s their decline in the 1970s and 198Os, and their resurgence in the 1990s. Travelers have become an increasingly important television programming tool as broad- cast networks compete for market share.  相似文献   

Profit Sharing in a Closed Content Market     

Jungsuk Oh 《Journal of Media Economics》2013,26(1):55-75

Many media industries can be characterized as a closed content market in which only subscribers of the distribution network operator (Network Provider [NP]) have access to the content provided by a content provider (CP). In these markets, the NP frequently charges the CP for providing billing and connectivity services to potential customers. Due to this carriage payment, the closed content market has structural similarity to the coalitional form game. Consequently, concepts of superadditivity, the core, and the Shapley value can be applied to determine what constitutes a sustainable and fair share of the CP's profit that could be paid to the NP as a carriage payment. This article addresses issues concerning the existence of the sustainable and fair profit allocation in a closed content market like the one described previously.  相似文献   

Pedagogical Transformations of Science Content Knowledge in Korean Elementary Classrooms     

Phil Seok Oh  Kyoung Suk Kim 《International Journal of Science Education》2013,35(9):1590-1624

While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.  相似文献   

Learning Visualization Strategies: A qualitative investigation     

Daniel Halpern  Kyong Eun Oh  Marilyn Tremaine  James Chiang  Karen Bemis  Deborah Silver 《International Journal of Science Education》2013,35(18):3038-3065

The following study investigates the range of strategies individuals develop to infer and interpret cross-sections of three-dimensional objects. We focus on the identification of mental representations and problem-solving processes made by 11 individuals with the goal of building training applications that integrate the strategies developed by the participants in our study. Our results suggest that although spatial transformation and perspective-taking techniques are useful for visualizing cross-section problems, these visual processes are augmented by analytical thinking. Further, our study shows that participants employ general analytic strategies for extended periods which evolve through practice into a set of progressively more expert strategies. Theoretical implications are discussed and five main findings are recommended for integration into the design of education software that facilitates visual learning and comprehension.  相似文献   

What Teachers of Science Need to Know about Models: An overview     

Phil Seok Oh  Sung Jin Oh 《International Journal of Science Education》2013,35(8):1109-1130

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: meanings of a model, purposes of modelling, multiplicity of scientific models, change in scientific models and uses of models in the science classroom. First, a model can be defined as a representation of a target and serves as a ‘bridge’ connecting a theory and a phenomenon. Second, a model plays the roles of describing, explaining and predicting natural phenomena and communicating scientific ideas to others. Third, multiple models can be developed in science because scientists may have different ideas about what a target looks like and how it works and because there are a variety of semiotic resources available for constructing models. Fourth, scientific models are tested both empirically and conceptually and change along with the process of developing scientific knowledge. Fifth, in the science classroom, not only teachers but also students can take advantage of models as they are engaged in diverse modelling activities. The overview presented in this article can be used to educate science teachers and encourage them to utilise scientific models appropriately in their classrooms.  相似文献

A U‐Shaped Relation Between Sitting Ability and Upright Face Processing in Infants     

Cara H. Cashon  Oh‐Ryeong Ha  Casey L. Allen  Amelia Cevelle Barna 《Child development》2013,84(3):802-809

A growing body of research indicates connections exist between action, perception, and cognition in infants. In this study, associated changes between sitting ability and upright face processing were tested in 111 infants. Using the visual habituation “switch” task (C. H. Cashon & L. B. Cohen, 2004; L. B. Cohen & C. H. Cashon, 2001), holistic processing of faces was assessed in same‐aged non‐ and near sitters (22–25 weeks) and same‐aged new and expert sitters (27–32 weeks). U‐shaped relation was found between sitting stage and holistic face processing such that only nonsitters and expert sitters processed faces holistically. It is posited that the results are due to a reorganization of the upright face‐processing system resulting from infants' learning to sit independently and trying to incorporate the meaning of upright faces.  相似文献
