ABSTRACT This article reports on a study designed to explore how digital and physical reproductions of original artifacts could be incorporated into museum programs that teach visitors about mechanical motion. Museum visitors were introduced to 3 different types of models through 2 different programs: an engineering design challenge and an exhibit interpretation exploring mechanical motion in every-day objects. Research, based on visitor observation and interviews (n = 79), explored how user interaction with the digital and physical models compared with interactions with the original artifacts, assessed what effect the integration of digital and physical models had on learning, and examined what the learning experience looked like for learners using the mechanisms in the museum activities. Analysis of the learning conversations in additional in-depth case studies (n = 8) for both programs provides a detailed look at how visitors integrated the 3 different model types into their group's experience. Results showed that visitors' usage of, attitudes toward, and learning from the three different types of mechanical models varied based on the visitor or educators' perceived value of the particular model, which was impacted by the context in which the objects were presented. 相似文献

Family climate is theorized to influence psychosocial functioning of adolescents both with and without type 1 diabetes. Family system theory considers adolescent behavior as a function of the dynamic interactions between family members. In the present multi-informant longitudinal study, we used two-step cluster analysis to empirically derive family climates based on four family dimensions (i.e., cohesion, conflict, organization, and control) at baseline and we related these climates to longitudinal assessments of adolescent psychosocial functioning. Analyses were conducted on a total of 220 adolescents (102 with diabetes, 118 healthy controls), 217 mothers, and 168 fathers. Cluster analysis on the four FES subscales revealed the following four family climates: a cohesive (moderately high on cohesion and moderately low to low on the other dimensions), balanced (high on cohesion and organization, low on conflict), conflictual (high on conflict, low on organization and cohesion), and controlling (high on control, moderately high on conflict and organization, moderately low on cohesion) climate. Adolescents with diabetes were somewhat overrepresented in the balanced climate, and underrepresented in the cohesive and conflictual climate as compared to their healthy peers. Consistent with hypotheses, we found that adolescents raised in cohesive or balanced climates fared better in terms of internalizing symptoms, externalizing symptoms, and self-concept as compared to adolescents raised in conflictual or controlling climates. Additionally, family climate was not associated with differential changes in outcome variables over time. These finding were consistent across informants and across time. Finally, these associations were not moderated by having type 1 diabetes. Suggestions for future research and practical implications are discussed. 相似文献

Recent evidence suggests that spatial frequency (SF) processing of simple and complex visual patterns is flexible. The use of spatial scale in scene perception seems to be influenced by people's expectations. However as yet there is no direct evidence for top-down attentional effects on flexible scale use in scene perception. In two experiments we provide such evidence. We presented participants with low- and high-pass SF filtered scenes and cued their attention to the relevant scale. In Experiment 1 we subsequently presented them with hybrid scenes (both low- and high-pass scenes present). We observed that participants reported detecting the cued component of hybrids. To explore if this might be due to decision biases, in Experiment 2, we replaced hybrids with images containing meaningful scenes at uncued SFs and noise at the cued SFs (invalid cueing). We found that participants performed poorly on invalid cueing trials. These findings are consistent with top-down attentional modulation of early spatial frequency processing in scene perception. 相似文献

Connine, Blasko, and Hall (Journal of Memory and Language 30:234–250, 1991) suggested that within a 1-second temporal window, subsequent biasing information can influence the identification of a previously spoken word. Four experiments further explored this hypothesis. Our participants heard sentences in which an ambiguous target word was followed less than or more than a second later by a word biased in favor of either the target word or another word. Overall, the effects of the contextual biases on responding, measured using phonemic restoration and phoneme identification, were almost as large after 1 second as before 1 second. The implications of these results for defining the window of contextual effects are discussed. 相似文献

The purpose of this study was to test the effectiveness of a spiritually-based intervention in the alleviation of subsyndromal anxiety and minor depression in an elderly population. Twenty-two residents of six continuing care communities diagnosed with minor depression participated in this study. There was a significant decrease in anxiety and a trend toward decreased depression. In addition, participants who continued to use the Prayer Wheel had a decrease in depression scores, while those who did not had an increase in depression scores. These findings suggest that use of the Prayer Wheel may promote psychological well-being among older adults. 相似文献

Coping with stress is a major focus for chemically dependent persons in relapse prevention programs. The relationships among
coping and psychological distress were investigated in 71 men with substance use disorders, at both pre—and post-treatment.
It was predicted that low task-oriented coping, high emotion-oriented coping, and high avoidance-oriented coping would predict
psychological distress (e.g., anxiety and depression). It was also expected that use of task-oriented coping would increase
following treatment and that use of emotion-oriented coping and avoidance-oriented coping, and reported levels of psychological
distress would all decrease following treatment. Participants completed the Coping Inventory for Stressful Situations and
the General Health Questionnaire, took part in an intensive treatment program (e.g., relaxation, drug education, stress management)
and completed these questionnaires again following treatment. Results indicated that high emotion-oriented coping predicted
hypochondriasis, anxiety and depression. Task-oriented and avoidance-oriented coping did not predict psychological distress,
although task-oriented coping was negatively related to hypochondriasis, anxiety and depression. The results regarding change
in coping styles and levels of psychological distress were as hypothesized, except that avoidance-oriented coping did not
significantly change following treatment. Theoretical and practical implications of the research are discussed. 相似文献

This is an account of some of the learning experiences of mature students undertaking a Level 2 Diploma course in Person-Centred Counselling over four terms in a higher education establishment in England. The central question driving this research stemmed from a desire to understand the student experience of becoming professional. Therefore the question was that of qualitative inquiry: ‘What are the experiences of mature learners on person-centred counselling courses within higher education?’ This paper discusses students’ perceptions of training and the ways in which they evaluate their status as professionals. 相似文献

In two studies examining resource allocation, support is found for the notion that group decisions are affected in systematic ways depending on whether or not there was individual consideration of the problem before meeting as a group. Specifically, compared to no prior consideration groups, prior consideration groups (1) escalate their commitment more in progress (i.e., ongoing) decisions, and (2) are less willing to concentrate resources on a single project in adoption (i.e., resource utilization) decisions. The findings challenge the blanket assertion that promoting divergent views in a group decision context is always related to better decisions. 相似文献
