Entering the European Information Society: Four Rural Development Projects     

Pernilla Gripenberg  Ingjerd Skogseid  Francesco Botto  Andrea Silli  Virpi Kristiina Tuunainen 《The Information Society》2004,20(1):3-14

This article compares four European information and communication technologies (ICT) development projects spawned by national and EU initiatives to create the “European information society.” These projects, which sought to support learning and better use of ICT, were all the result of opportunities opened up by political initiatives. The analysis indicates that the main problems that afflict these projects stem from varied expectations and interests of the major actors. These problems can be mitigated considerably if a feeling of ownership is generated among the participants. This sense of belonging, however, is difficult to foster in a “top-down” project. Hence there is a need for a better balance between the “top-down” and “bottom-up” influences in the development of such projects.  相似文献

Weak Ties in Networked Communities     

Andrea L. Kavanaugh  Debbie Denise Reese  John M. Carroll  Mary Beth Rosson 《The Information Society》2005,21(2):119-131

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals-is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities.  相似文献   

Patterns of Nonverbal Adaptation in Supportive Interactions     

Graham D. Bodie  Kaitlin E. Cannava  Andrea J. Vickery  Susanne M. Jones 《Communication Studies》2016,67(1):3-19

This study seeks initial evidence for the patterns of nonverbal adaptation predictive of emotional improvement after a troubles talk conversation. A total of 128 dyads composed of two unacquainted individuals engaged in a 5-minute conversation about a stressful event, and the nonverbal behaviors of both the supportive listener and discloser were coded for immediacy. We detected a general pattern of matching between interlocutors, which was positively associated with disclosers’ reported emotional improvement above and beyond listener immediacy. Importantly, we found primary support for a discloser-matching model whereby emotional improvement is a function of disclosers matching highly immediate listeners but no support for a listener-matching model whereby emotional improvement is a function of listeners matching disclosers to signal empathy.  相似文献   

Personal,professional, political: an exploration of science teacher identity development for teaching climate change     

Andrea Drewes 《Environmental Education Research》2020,26(4):611-612

Abstract

Climate change presents societal and environmental challenges, as well as educational ones. Obstacles abound within teaching and learning climate change, related to its complex nature, the proliferation of misinformation, and its absence from many science curricula. Efforts have previously been made to study teacher content knowledge and beliefs on climate change with varying results. This study employed identity as a theoretical framework to examine aspects of climate change teaching. This study followed a reflexively iterative process that enabled the construction of a conceptual model for identity development. This model demonstrates multifaceted influences including personal, professional, and political elements, and the dynamism these elements exhibit over time. This conceptual model is best described via five trends: Personal Valuation of Nature; Experiences in Science Teaching and Learning; Teacher Instructional Support and Agency; Epistemic Evidence-based Instruction; and Civic and Social Awareness via Socioscientific Literacy. The presence and strength of enactment of each trend led to the development of four possible constructions of identity: Passionate Environmentalist, Student Interest Engager, Content First Educator, and Civic and Epistemic Skills Promoter. Most frequently teachers exhibited combinations of identities and often created a unique amalgam of multiple dimensions of identities in action.  相似文献   

A Model of School Counseling Supervision: The Goals,Functions, Roles,and Systems Model     

Chris Wood  Andrea Dixon Rayle 《Counselor Education & Supervision》2006,45(4):253-266

The authors outline the Goals, Functions, Roles, and Systems Model (GFRS), a school counseling—specific model for supervising school counselors‐in‐training (SCITs). The GFRS was created as a guide for assisting in supervising and preparing SCITs for the multifaceted tasks they will undertake in their internships and careers. The components of this model are described within the context of the systems influencing supervision of SCITs. The GFRS is detailed to illustrate how it meets the specific needs of school counseling supervision. Examples are included of the GFRS when applied in supervision.  相似文献

Computer science and engineering: utilizing action research and lesson study     

Andrea C. Burrows  Mike Borowczak 《Educational Action Research》2019,27(4):631-646

ABSTRACT

This article explores one group’s use of action research (AR) and lesson study in three US university-level computer science courses affecting 85 undergraduate computer science and engineering students. It offers an overview of three areas including AR, lesson study, and engineering soft skills. The research group identified a problem: undergraduate engineering student soft skill understanding. The group collaborated to enhance participant engagement with this problem by utilizing one lesson focused on soft skills over three research lesson iterations in three distinct university semesters (2017-2018). Field notes were the main data collection method. Observational field notes were recorded in the three research lesson iterations, and themes from the notes were identified. The group valued peer interactions, and the research lesson adaptations as well as pedagogical changes were based on evidence. Four themes were identified, and participant comments were considered as the lessons became more focused . The research group argues that AR and lesson study are separate and distinct ventures based on this yearlong experience, which is counter to some other literature presented. Implications are large for all stakeholders interested in AR, lesson study, soft skill utilization, conflict management, and participant learning impact. Possibilities for enhanced participant engagement exists with honed lesson pedagogy.  相似文献   

Response rate is not an effective mediator of learned stimulus equivalence in pigeons     

Frank AJ  Wasserman EA 《Learning & behavior》2005,33(3):287-295

We explored response rate as a possible mediator of learned stimulus equivalence. Five pigeons were trained to discriminate four clip art pictures presented during a 10-sec discrete-trial fixed interval (FI) schedule: two paired with a one-pellet reinforcer, which supported a low rate of responding, and two paired with a nine-pellet reinforcer, which supported a high rate of responding. After subjects associated one stimulus from each of these pairs with a discriminative choice response, researchers presented two new clip art stimuli during a 10-sec FI: one trained with a differential reinforcement of low rate schedule (DRL) after the FI and the other trained with a differential reinforcement of high rate schedule (DRH) after the FI. Each of the stimuli that were withheld during choice training was later shown to see if the choice responses would transfer to these stimuli. The results suggest that response rate alone does not mediate learned stimulus equivalence.  相似文献   

Food sharing in albino rat pups: Does familiarity breed contempt?     

Georgia D. Wills  Frank R. Moore  Andrea L. Wesley  Barry Friedman 《Learning & behavior》1984,12(1):106-108

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.  相似文献
