Physical field trips to scientists?? work places have been shown to enhance student perceptions of science, scientists and science careers. Although virtual field trips (VFTs) have emerged as viable alternatives (or supplements) to traditional physical fieldtrips, little is known about the potential of virtual field trips to provide the same or similar science career exploration advantages as physical field trips. The overarching goal of this paper is to describe a VFT, zipTrips?, designed to provide middle school students, especially those in resource limited rural areas, with access to university scientists. Using zipTrips as a case example, the paper identifies and describes some of the core characteristics and elements of high quality authentic VFTs that foster student-scientist interactions. In addition, the paper uses program evaluation data to examine the impact of zipTrips on student perceptions of scientists.  相似文献   

Using a wiki to facilitate an online professional learning community for induction and mentoring teachers     

Amy Hutchison  Jamie Colwell 《Education and Information Technologies》2012,17(3):273-289

The purpose of this case study was to report on the use of a wiki as a tool for conducting online professional learning communities (OLCs) with 26 induction and mentor teachers. Data sources include teachers’ wiki postings and teacher interviews. Results indicate that: (a) Web 2.0 tools may be most effective in OLCs when the social features are utilized in addition to the features that enable task completion; (b) Using Web 2.0 tools restrictively, and without consideration of their affordances, may inhibit the success of OLCs; (c) Online learning communities for induction teachers may be most effective when supplemented with face-to-face discussion; and (d) A task-driven environment in OLCs can encourage professional dialogue and reflection, but may make induction teachers feel isolated and unsupported.  相似文献   

Strategic Alliance Poker: Demonstrating the Importance of Complementary Resources and Trust in Strategic Alliance Management     

Christopher R. Reutzel  William J. Worthington  Jamie D. Collins 《Decision Sciences Journal of Innovative Education》2012,10(1):109-115

Strategic Alliance Poker (SAP) provides instructors with an opportunity to integrate the resource based view with their discussion of strategic alliances in undergraduate Strategic Management courses. Specifically, SAP provides Strategic Management instructors with an experiential exercise that can be used to illustrate the value creation potential of complementary resources and the role of trust in fostering resource sharing in strategic alliances. A discussion of the theoretical background, implementation, implications, and results of SAP is provided in this paper.  相似文献   

Prominent Messages in Television Drama Switched at Birth Promote Attitude Change Toward Deafness

The study at hand employed a pre- versus posttest experimental design to test the effects of television drama Switched at Birth on viewers’ attitudes toward deafness. This program tells the story of two teenage girls (one of whom is deaf) and their struggles to relate to their peers and families after discovering they were switched as newborns. Two hundred eleven female adults completed pre- and postexposure measures utilizing Cooper, Rose, and Mason's (2004 Cooper , A. , Rose , J. , &; Mason , O. ( 2004 ). Measuring the attitudes of human service professionals toward deafness . American Annals of the Deaf , 148 , 385 – 389 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Attitudes to Deafness measure, the items of which were categorized according to thematic dimensions. After exposure to one of three episodes, viewers’ attitudes toward deafness significantly improved overall, although significant differences in attitude changes varied by episodes and dimensions. The three thematic dimensions that were most strongly represented in the program (social interaction, deafness as a handicap, and language issues) appeared to show the strongest attitude change. Positive attitude changes were observed on social interaction and deafness as handicap dimensions, which was consistent with program content depicting positive deaf-hearing friendships and capable deaf characters. However, attitudes on the language issues dimension showed a negative shift, possibly due to the way that deaf characters communicated with hearing characters onscreen.  相似文献   

Remembering Things Without Context: Development Matters     

Jamie O. Edgin  Goffredina Spanò  Kevin Kawa  Lynn Nadel 《Child development》2014,85(4):1491-1502

Spatial context supports memory retrieval in adults. To understand the development of these effects, context effects on object recognition were tested in neurotypical children ages 3 years to adulthood (n 3–6 years = 34, n 10–16 years = 32, n college age = 22) and individuals with Down syndrome (DS) ages 10–29 years (n = 21). Participants engaged in an object recognition task; objects were presented in scenes and either remained in that same scene or were removed at test. In some groups (< 4.5 years and with DS) context effects were present even though object recognition was poor. After 4.5 years, children demonstrated memory flexibility, while later in adolescence context effects reemerged, showing nonlinearity in the development of these effects.  相似文献   

Teachers' Awareness of the Learner–Teacher Interaction: Preliminary Communication of a Study Investigating the Teaching Brain     

Vanessa Rodriguez  S. Lynneth Solis 《Mind, Brain, and Education》2013,7(3):161-169

A new phase of research on teaching is under way that seeks to understand the teaching brain. In this vein, this study investigated the cognitive processes employed by master teachers. Using an interview protocol influenced by microgenetic techniques, 23 master teachers used the Self‐in‐Relation‐to‐Teaching (SiR2T) tool to answer “What are you focusing your mind on throughout the process of teaching?” A number of emergent themes were identified in participants' responses and one, awareness of interaction, is discussed here. This theme refers to teachers' recognition of the learner–teacher (L‐T) relationship as a separate entity or system. Within interaction, at least three types of awarenesses emerged in teachers' responses: (1) connection, (2) collaboration, and (3) mutual effects. Furthermore, some teachers described a sense of synergy with their students due to this L‐T interaction. The results suggest that a teacher's awareness of interaction plays an important role in the teaching brain, and support the implications of the proposed teaching brain framework.  相似文献   

Commercial ethnicity: Language,class and race in the marketing of the hispanic audience     

América Rodriguez 《The Communication Review》2013,16(3):283-309

This essay examines the historical construction of the Hispanic audience and analyzes how contemporary Hispanic audience researchers/marketers have disrupted that unitary, essentialist construction by segmenting the Hispanic audience by class. The principal tool in this effort is language: the Spanish language is proxy for the “mass” of lower socioeconomic class Hispanic audience; English language usage by Hispanics is the sign of a higher class of Hispanic audience. The clearly defined panethnic conceptualization of the Hispanic audience, the nexus of which is the Spanish language, has been blurred. The study draws on interviews with Hispanic media marketers and audience researchers and on analysis of Hispanic market research reports.  相似文献   

Eysenck's BIG THREE and communication traits: Communication traits as manifestations of temperament     

James C. McCroskey  Virginia P. Richmond  Alan D. Heisel  Jamie L. Hayhurst 《Communication Research Reports》2013,30(4):404-410

Two studies are reported which sought to determine the possible limitations of the proposition that “temperament is manifest through communication.”; The results of earlier studies suggest that many communication related traits indeed are correlated with one or more temperament variables. In the present study Willingness to Communicate, Singing Apprehension, and Innovativeness were found to be associated with one or more of the BIG THREE temperament variables. Writing apprehension was found to have no meaningful relationship with any of the temperament variables. It is concluded that, while most important oral communication traits probably are correlated with one or more temperament traits, some other communication traits, like writing apprehension, may not be.  相似文献   

The effectiveness of appeals used in Cambodian and Vietnamese magazine ads     

Sela Sar  Lulu Rodriguez 《亚洲交流杂志》2013,23(6):529-548

In this two-part study, a content analysis of advertisements published in Cambodian and Vietnamese magazines was first conducted to determine the kinds of advertising appeals (functional, individualistic, and collectivistic) that were most frequently employed. The findings indicated that across product types, the Cambodian ads contained more individualistic appeals. The Vietnamese ads, on the other hand, depicted more collectivistic and functional appeals. Next, an experiment was conducted to determine audience response to the use of three appeals in ads that promote four product types (informative, affective, habit-forming, and self-satisfaction). Vietnamese participants responded more positively to functional appeals across product types. They also preferred collectivistic rather than individualistic appeals for ads that promote habit-forming and self-satisfaction products. Cambodian consumers, on the other hand, registered more positive attitudes toward ads with individualistic and functional appeals.  相似文献   

Implementing Twitter in a Health Sciences Library     

Colleen Cuddy  Jamie Graham  Emily G. Morton-Owens 《Medical reference services quarterly》2013,32(4):320-330

The NYU Health Sciences Libraries created an account on Twitter, a microblogging service, as a new outreach tool marketed to students, faculty, and staff. The team used Twitter to promote resources, events, and news. Twitter is a part of a pipeline of information that also includes the library's Web site and Facebook. Although it is difficult to measure the effectiveness of a social networking tool, the overhead of using Twitter is so low that it merits consideration.  相似文献
