The digital age has not simply changed the nature of resources and information; it has transformed several basic social and economic enterprises. Contemporary society—the settings where we live, work, and learn—has likewise changed dramatically. Both the amount of information and access to it have grown exponentially; a significant potential for using varied resources in numerous ways for instruction and learning has emerged. However, several issues related to the educational uses of varied resources (e.g., people, place, things, ideas) must be addressed if we are successfully to implement resource-based learning environments. In this paper, we trace the changing nature of resources and perspectives in their use for learning in the digital age, describe the overarching structures of resource-based learning environments, and identify key challenges to be addressed.  相似文献

Since Grossman’s seminal paper in 1972, there have been a number of studies concerning the effect of education on health and health care demand. Though several studies have distinguished between preventive and curative care, no study has investigated the effects of general education on the utilization of unnecessary emergency department use. We test whether general education reduces “potentially unnecessary” emergency department utilization and provide a measure of the resulting private benefits associated with increased education. Our results partially confirm our hypothesis regarding “potentially unnecessary” emergency department use. We find that moving from a high school to greater than high school education appears to reduce “potentially unnecessary” emergency department use, with the impact being greater among the insured. However, though reducing the education level from high school to less than high school increases “potentially unnecessary” emergency department use among the insured as predicted, it has the opposite impact on the uninsured.  相似文献

Three experiments tested the hypotheses that (1) the onsets of prolonged, fixed-duration treatment shocks (shock treatment, or ST) serve as cues for fear conditioning to the ongoing painful effects of these stimuli, and (2) this acquired fear transfers to and influences shock-motivated test performances in predictable ways. Experiments 1 and 2 involved spaced post-ST presentations of very brief shocks (a presumed analogue of the onsets of treatment shocks) as a means of extinguishing the fear putatively associated with shock cues. This procedure reduced defecation by ST subjects over blocks of extinction sessions and nullified the punishment intensification effect that was otherwise shown to be a consequence of ST. As a further test of the shock-cue hypothesis, Experiment 3 involved relatively massed presentations of these brief shocks prior to ST in a latent-inhibition procedure (Lubow, 1973). This briefshock regimen also nullified the ST punishment intensification effect but did not impair the transituational transfer of contextual fear. In contrast, the group that was given the same brief shock regimen following ST showed enhancement of the punishment effect. With respect to current theoretical accounts of ST effects, these data were most consistent with notions that rely on an acquired-fear construct.  相似文献

This article summarizes a reformulation of the main findings and perspectives from a cross-sectional and longitudinal qualitative study of the development of 100 counselors and therapists. The results are presented as a phase model and as a formulation of 14 themes of counselor/therapist development. The following six phases are described: The phases of the lay helper, the beginning student, the advanced student, the novice professional, the experienced professional, and the senior professional. The themes describe central processes of counselor/therapist development. The themes are addressing different issues such as shifts in attentional focus and emotional functioning, the importance of continuous reflection for professional growth, and a life-long personal/profession integration process. Sources of influence for professional functioning and development are described. The results show consistently that interpersonal experiences in the personal life domain (early family life and adult personal life) and the professional life domain (interacting with clients, professional elders, and peers) are significant sources of influence for professional development.  相似文献

This longitudinal study used latent growth curve modeling to investigate English literacy development in a sample of Spanish-speaking language minority students from third through eighth grade. This study also compared the sample’s literacy development to the entire population of California students using state standardized test data. Second, this study examined the contributions of a variety of bilingual measures of kindergarten letter knowledge, phonological awareness, word reading, and vocabulary to literacy development. Results demonstrated the present sample scored below average in literacy compared to the overall population of California students across years, but made slight gains to narrow the achievement gap. The greatest gains were obtained between fourth and fifth grade, but plateaued thereafter. Results concerning the second research questions showed that the third grade literacy intercept was predicted by kindergarten English letter knowledge, Spanish onset, Spanish word reading, and English vocabulary. However, English literacy development through eighth grade was only predicted by kindergarten English and Spanish vocabulary. Findings support arguments for educational efforts to target oral language instruction for these students in early elementary and instruction in both languages may provide the greatest benefit. Instructional implications are discussed.  相似文献

Interest in career development and career counseling is growing in Korea. Nevertheless, neither the research nor the literature adequately address the question as to what applications can be cross-culturally transferred from career counseling centers in the United States to Korea. This study qualitatively examines the practice of career counseling in seven university career counseling centers in the United States in a search for concepts and methods that may be cross-culturally applied to Korean universities. Nine categories of data emerged in our qualitative analysis of information gathered: (a) types of systems; (b) staff; (c) services provided; (d) career assessments; (e) alumni networks; (f) workshops and outreach; (g) publicity; (h) information technology; and (i) facilities. Applications and ideas for the Korean context, limitations, and suggestions for future research are discussed.  相似文献
