A Practical Introduction to Authoring for Computer-Assisted Instruction. Part 7: Graphic support     

P Barker  T Skipper 《British journal of educational technology : journal of the Council for Educational Technology》1986,17(3):194-212

Images provide a useful method of presenting information to an audience. In a learning situation the use of pictorial forms can offer a high-bandwidth mechanism for the transfer of information between an instructor and a student. This paper discusses some ways of providing graphic support in a computer-based learning environment and describes some approaches to the provision of authoring facilities that utilize this technique.  相似文献

Peer victimization, poor academic achievement, and the link between childhood externalizing and internalizing problems     

van Lier PA  Vitaro F  Barker ED  Brendgen M  Tremblay RE  Boivin M 《Child development》2012,83(5):1775-1788

This study explored whether early elementary school aged children’s externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early internalizing problems contributed to an increase in externalizing problems. The study examined 1,558 Canadian children from ages 6 to 8 years. Externalizing and internalizing problems, peer victimization, and school achievement were assessed annually. Externalizing problems lead to academic underachievement and experiences of peer victimization. Academic underachievement and peer victimization, in turn, predicted increases in internalizing problems and in externalizing problems. These pathways applied equally to boys and girls. No links from internalizing to externalizing problems were found.  相似文献   

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   

Meeting needs assessment challenges: Applying the performance pyramid in the U.S. Army     

Linsey M. Barker Steege  Rose M. Marra  Keri Jones 《Performance Improvement》2012,51(10):32-41

This article describes an application of the Performance Pyramid, a needs assessment framework that supports a holistic view of an organization allowing assessors to identify how organizational culture may affect performance. We illustrate use of the Performance Pyramid for a needs assessment with human systems integration practitioners in the U.S. Army. We describe how the Performance Pyramid guided our methods, data collection, and results interpretation and discuss advantages and disadvantages of the methodology.  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     

Seon-Kyoung An  Llewyn Elise Paine  Jamie Nichole McNiel  Amy Rask  Jourdan Taylor Holder  Duane Varan 《Mass Communication and Society》2014,17(2):195-216

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
