Personal Leadership in Practice: A Critical Approach to Instructional Design Innovation Work     

Marcia L Ashbaugh 《TechTrends》2013,57(5):74-82

An argument is made in this article for a link between leadership and innovation, when innovation is an outcome of the work approaches and practices that underpin an educational technologist’s academic course designs. The practice of instructional design (ID) is continually being challenged to rethink its conceptualization of academic course designs, especially for web-based affordances, to release designers to new processes that more align with the modern use of communication devices and networks. I suggest here that the time has come for ID to leave non-adaptive, linear thinking behind not only in how and when to prescribe certain technologies but in how to approach educational change with an adaptation of personal leadership that drives innovation (Ashbaugh, 2012).  相似文献   

A framework for assessing market entry opportunities for internet‐based TV     

Claudia Löbbecke  Marcia Falkenberg 《媒体管理杂志》2013,15(2):95-104

Abstract

The advent of the Internet alleviates the access bottleneck to TV distribution channels and softens licensing requirements. This lowers entry barriers to TV markets via the Internet in various forms. This paper takes the German TV sector as an example to analyse the attractiveness of TV markets for new entrants. A sequential framework for entering TV markets is introduced. The skills set of an Internet‐based TV provider for such an entry is examined. Technical feasibility, legal aspects, and potential sources of revenue are considered.

Potential above average profits due to the market's oligopolistic structure, as well as an increased contestability thanks to lower market entry barriers seem to render the German TV market attractive for new entrants. In early 2002, Internet‐based TV still faced severe technical and legal constraints. The analysis suggests that once these constraints have been overcome, the Internet could be an attractive additional distribution channel for some types of television content. While existing revenue sources from the TV sector are expected to be transferable to a certain degree, the value of innovative revenue sources based on online sales cannot yet be determined. This value will depend on the future acceptance of interactivity by the viewer (e. g. Owen 1999).  相似文献   

A Review of “RDA Vocabularies for a Twenty-First-Century Data Environment”     

Marcia Salmon 《Cataloging & classification quarterly》2013,51(1):49-51

Automation and economic cutbacks are forcing many large libraries to alter traditional organizational structures. This paper describes the reorganization of technical and public service activities in the University of Illinois Library at Urbana-Champaign. The decentralization of original cataloging functions is examined, particularly as implemented in the Education and Social Science Library (ESSL), and the effect on management of original cataloging activities and cataloging norms is discussed.  相似文献

Technology and science education: Starting points,research programs,and trends     

Marcia Linn 《International Journal of Science Education》2013,35(6):727-758

Over the past 25 years, information and communication technologies have had a convoluted but ultimately advantageous impact on science teaching and learning. To highlight the past, present, and future of technology in science education, this paper explores the trajectories in five areas: science texts and lectures; science discussions and collaboration; data collection and representation; science visualization; and science simulation and modeling. These trajectories reflect two overall trends in technological advance. First, designers have tailored general tools to specific disciplines, offering users features specific to the topic or task. For example, developers target visualization tools to molecules, crystals, earth structures, or chemical reactions. Second, new technologies generally support user customization, enabling individuals to personalize their modeling tool, Internet portal, or discussion board. In science education, designers have tailored instructional resources based on advances in understanding of the learner. More recently, designers have created ways for teachers and students to customize learning tools to specific courses, geological formations, interests, or learning preferences.  相似文献

Advancing intercultural competency: Canadian engineering employers’ experiences with immigrant engineers     

Marcia Friesen  Sandra Ingram 《European Journal of Engineering Education》2013,38(2):219-227

This paper explores Canadian engineering employers’ perceptions of and experiences with internationally educated engineers (recent immigrants to Canada) employed in their organisations for varying lengths of time. Qualitative data were collected from employers using focus group methodology. Findings reflected employers’ observations of culturally different behaviours and characteristics in their internationally educated employees, employers’ reactions to cultural differences ranging from negative attributions to tolerance, and the implementation of largely ad hoc intra-organisational strategies for managing cultural differences in employer–employee relationships. Findings exposed the lack of corporate intercultural competency in the Canadian engineering profession. Equity and gatekeeping implications are discussed.  相似文献   

Education for Interdisciplinary Community Collaboration and Development: The Components of a Core Curriculum by Community Practitioners     

Martha Lucia Garcia  Terry Mizrahi  Marcia Bayne-Smith 《Journal of Teaching in Social Work》2013,33(2):175-194

Social workers are actively engaging in the practice of interdisciplinary community collaboration (ICC) with the goal of bringing diverse groups together to improve the conditions of communities and enhance the quality of life of population groups. Yet, collaborations are challenging and require great skill and commitment. The pedagogy and the content of curricula have become a more prominent part of teaching to macro practice students and practitioners the art of effectively convening and moving collaborative efforts forward. This article adds to the literature on the content and methods of teaching students and novice practitioners the competencies embedded in ICC. It provides empirical data from six focus groups of experienced community practitioners (social workers and others) in New York City who identified components of a core curriculum for this work. Eight months later, these 33 community practitioners were asked to reprioritize the topics and concepts that they had collectively identified at the earlier time. Skills such as the ability to share power, manage differences, include the constituency and diplomacy are among those discussed. Core curriculum themes, the pedagogy and process, and the attributes and values necessary for training an ICC practitioner are presented.  相似文献   

Toward a Learning Technologies knowledge network   总被引：3，自引：0，他引：3

The National Science Foundation-funded Center for Innovative Learning Technologies (CILT) is designed to be a national resource for stimulating research and development of technology-enabled solutions to critical problems in K-14 science, math, engineering and technology learning. The Center, launched at the end of 1997, is organized around four themes identified as areas where research is likely to result in major gains in teaching and learning, and sponsors research across disciplines and institutions in its four theme areas. CILT brings together experts in the fields of cognitive science, educational technologies, computer science, subject matter learning, and engineering. It engages business through an Industry Alliance Program and is also training postdoctoral students. CILT's founding organizations are SRI International's Center for Technology in Learning, University of California at Berkeley (School of Education and Department of Computer Science), Vanderbilt University's Learning Technology Center, and the Concord Consortium. Through its programs, CILT seeks to reach beyond these organizations to create a web of organizations, individuals, industries, schools, foundations, government agencies, and labs, that is devoted to the production, sharing and use of new knowledge about how learning technologies can dramatically improve the processes and outcomes of learning and teaching. This paper describes the rationale and operations of the Center, and first-year progress in defining a set of CILT partnership projects with many other institutions that came out of our national theme-team workshops. Roy Pea, of SRI International, is Director of CILT. Marcia Linn (U. California, Berkeley), John Bransford (Vanderbilt University), Barbara Means (SRI International), and Robert Tinker (Concord Consortium), serve as CILT's coprincipal investigators. Sherry Hsi (Ubiquitous Computing) and Sean Brophy (Technology and Assessment Models) are among the first group of CILT Postdoctoral Fellows. Jeremy Roschelle (SRI International) and Nancy Songer (University of Michigan) are CILT theme-team leaders. Roy Pea and Marcia Linn would like to thank the Spencer Foundation for support during their year at the Center for Advanced Study in the Behavioral Sciences, Stanford University, in which they developed the CILT concept with the other authors. CILT is funded by National Science Foundation grant #CDA-9720384. Pea and Linn would also like to acknowledge contributions to this article by the many authors of CILT partnership project proposals, and by theme-team leaders. The authors thankfully acknowledge Donna Baranski-Walker for her many contributions to developing the CILT Industrial Alliance Program while serving as its Director in 1998.  相似文献   

A step function in pigeons’ temporal generalization in the peak shift task     

Marcia L. Spetch  Ken Cheng 《Learning & behavior》1998,26(1):103-118

Pigeons were reinforced for pecking a key following one signal duration (S+) but not following another signal duration (S?). The S+ and S? were 2.52 and 5.67 sec, respectively, counterbalanced across birds. Subsequent generalization tests with a range of signal durations revealed a step function, with high response rates for all durations on the S+ side of the distribution, low response rates for all durations on the S? side, and an intermediate rate for the intermediate duration. A comparison group of pigeons trained with only the S+ duration showed a flat generalization function. For the discrimination-trained birds, the delay between signal termination and opportunity to respond was subsequently varied during generalization testing. A step function again appeared, and no evidence of subjective shortening over the delay was found. The overall pattern of results suggests that the birds categorized the temporal signal into two classes and retained a categorical code over the delay.  相似文献
