The role of context in learning and instructional design 总被引:4,自引:0,他引:4
Martin Tessmer Rita C. Richey 《Educational technology research and development : ETR & D》1997,45(2):85-115
Context is a pervasive and potent force in any learning event. Yet instructional design models contain little guidance about how to accommodate contextual elements to improve learning and transfer. This paper defines context, outlines its levels and types, specifies some pertinent contextual factors within these types, suggests methods for conducting a contextual analysis and utilizing its results for instructional design, and outlines future issues for context-based instructional design. The incorporation of a contextual approach to instruction will make our design models systemic as well as systematic. 相似文献

Following landmark legislation passed more than 20 years ago, university–industry relationships have now become central to understanding the changing role of research universities in American Society. The paper analyzes the development of university–industry partnerships during the 1990s. Past studies have used a broad array of measures of ties and a variety of research methodologies, but they have shared a focus on top collaborators or on samples of universities skewed toward the top. However, findings based on top collaborators may not be valid for other universities. Universities involved in mid- to low-levels of collaboration are qualitatively different in many ways from the more extensively studied set of top collaborators, suggesting that characteristics affecting university–industry ties may not be the same for these institutions. The paper shifts the focus away from top collaborators to this sizable and less studied majority. In general, we find that the same characteristics predicting high levels of involvement for the sample as a whole also predict high levels of involvement for the sub-sample of mid- and low-level collaborators. However, We find some particular characteristics of these institutions, such as land grant status, are also associated with stronger ties to industry, and that some characteristics of 25 top institutions do not predict the level of involvement of these lower-level collaborators. We will discuss whether the licensing of new technology is likely ever to become an important source of net revenues for current middle and low-level collaborators. Our findings raise doubts about whether many universities below the top 25 will earn substantial net revenues from licensing, though they do not dispute the potential service value of these ties. The study is based on examination of a wide range of potential influences on university–industry collaboration for institutions that are not currently among the most heavily involved in partnerships. These include status, other institutional characteristics (such as size and control), investment in science and engineering, and characteristics of offices or technology transfer. 相似文献

School–university partnerships are not uni-dimensional projects. Success in these partnerships can be found in loosely-coupled systems such as client–server partnerships and in more tightly-coupled systems such as collaborative development centers. Using a comparative case study approach, we explore two school–university partnership case studies and propose a framework for identifying and evaluating partnerships as learning systems. The structure of the partnership has implications for the focus of organizational learning initiatives that can form the foundation of sustained, systemic internal evaluation. 相似文献

The South African National Integrated Early Childhood Development Policy was approved by the South African Cabinet in 2015. Given capacity and financial constraints, all services outlined cannot be implemented in a single step. Priorities must be set. We examine the budget implications (total cost and cost per child) and benefits of the four largest components of the Policy: interventions to improve pregnancy outcomes; home visits for at-risk mothers of children under 2 years of age; community-based playgroups for mothers and children, and center-based early childhood development services. Further, we identify which services are based on the strongest evidence, the value-based trade-offs that characterise the prioritising decisions, and which logistical factors favour alternative orderings of services. The interventions to improve pregnancy outcomes are low cost, based on sound evidence and would make use of the established healthcare infrastructure. Home visits for at-risk mothers are associated with improved development for targeted children and consequential benefits for caregivers and broader society. Playgroups are a promising low-cost intervention, but further evidence is required to determine their effectiveness. Centre-based services are expensive and generate smaller developmental returns, but provide childcare. The results highlight the value judgements required to determine the appropriate sequencing of interventions. 相似文献

Although attachment theory has long posited a link between early experiences of care and children's prosocial behavior, investigations of this association have not embraced the multifaceted nature of prosociality. This study is the first to assess associations between child attachment and independent observations of helping, sharing, and comforting. Attachment quality in 3- to 5-year-old children (N = 137) was linked to all three prosocial behaviors. Additionally, bifactor analyses revealed distinct associations between attachment and children's general prosocial dispositions and their specific abilities to meet the unique challenges of helping and, marginally, comforting. These findings underscore the importance of considering multiple explanations for links between attachment and prosocial behavior and provide novel insights into sources of variation in children's prosociality. 相似文献

The Legacy of Early Abuse and Neglect for Social and Academic Competence From Childhood to Adulthood
K. Lee Raby Glenn I. Roisman Madelyn H. Labella Jodi Martin R. Chris Fraley Jeffry A. Simpson 《Child development》2019,90(5):1684-1701
This study used data from the Minnesota Longitudinal Study of Risk and Adaptation (N = 267) to investigate whether abuse and neglect experiences during the first 5 years of life have fading or enduring consequences for social and academic competence over the next 3 decades of life. Experiencing early abuse and neglect was consistently associated with more interpersonal problems and lower academic achievement from childhood through adulthood (32–34 years). The predictive significance of early abuse and neglect was not attributable to the stability of developmental competence over time, nor to abuse and neglect occurring later in childhood. Early abuse and neglect had enduring associations with social (but not academic) competence after controlling for potential demographic confounds and early sensitive caregiving. 相似文献

A reciprocal relationship informing both research and practice is one of the primary goals in the emerging field of Mind, Brain, and Education (MBE), yet the field has little documentation and analysis of such collaborations. In this article, we present case studies of three research–practice partnerships taking place between scientists and educators. By comparing and contrasting these three partnerships we expect to illuminate common characteristics, challenges, and benefits that come with doing MBE work. 相似文献

Appetitive, aversive and avoidance responses to a flavoured solution in distinct contexts were examined. Rats placed in either
a white or black box were given access to saccharin. Consumption was followed by an injection of a toxin in one but not the
other box. Rats showed more aversive responses in anticipation of and during the presentation of saccharin in the box paired
with the toxin than in the box paired with vehicle. The reverse was true for appetitive responses. The acquisition of conditioned
avoidance paralleled the acquisition of aversive and appetitive responses. These findings demonstrate that the toxin does
not have to overlap exposure to contextual cues to produce conditioned aversive responses, that the aversive and appetitive
responses to a flavour can be modulated by visually distinct environments that predict the toxin, and that conditioned avoidance
and conditioned aversions develop simultaneously during acquisition. Thus, environmental cues can modulate anticipatory nausea
and may prove helpful in the control of nausea in clinical settings. 相似文献

Witnesses?? event recall and the realism in their evaluation of the correctness of their recall are of great importance in forensic processes. These issues were investigated in the present study by use of calibration methodology. More specifically, we analyzed the effects of two recalls of the same event (repetition) and of probes (non-informative follow-up questions at recall) on 9?C11?year-old children??s and adults?? open free recall and the degree of realism in the participants?? confidence judgments of the correctness of the recall after they had seen a short video clip. The findings were that repetition resulted in more units recalled both for children and for adults, and in that the children showed higher overconfidence compared with one recall, but not the adults. Moreover, when only the statements in the repetition conditions that were recalled twice were included in the analysis, higher confidence was found for the children (independent of an increase in the proportion correct statements of all statements) but not for the adults. Probing increased the number of units recalled for both children and adults, decreased the children??s proportion correct statements but not the adults??, decreased both children??s and adults?? confidence and increased the children??s overconfidence, but not the adults??. Finally, the combination of two recalls and probing disrupted the children??s but not the adults?? metacognitive performance. 相似文献
