Using Virtual Field Trips to Connect Students with University Scientists: Core Elements and Evaluation of zipTrips? 总被引:1,自引:1,他引:0

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

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 (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

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) 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

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

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 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

The present study investigated relations between proactive and reactive functions of physical and relational aggression and functional impairment across early childhood. It was hypothesized that reactive functions of aggression would be associated with functional impairment. Hypotheses with regard to proactive functions of aggression were exploratory. Participants were 36 children (22 girls) from a longitudinal study. At Time 1 (M = 50.31 months old, SD = 10.97), observations of aggressive behavior were collected during preschool free-play. At Time 2 (M = 73.33 months old, SD = 10.88), parent-report of functional impairment was collected. Reactive physical aggression was a significant and unique predictor of future impairment when controlling for gender and all other types of aggression. Implications of these findings are discussed from a developmental perspective. 相似文献
