The present paper focuses on the application of a structured template, maximum impact flow (MIF), in order to encourage young students in the area of optics and optical engineering. MIF introduces a template in terms of individual steps and linked functionality and is shown to fuse separate learning tools together into a cohesive unit. Prioritization and teaching structures are also discussed with the promotion of technology identified as a key factor. 相似文献

OBJECTIVE: The United States General Accounting Office (United States General Accounting Office [USGAO], 1989) report on out-of-home care affirmed that the foster care system is in crisis. To shed light on some factors that influence retention, the study reported here asked "What factors influence the satisfaction of foster parents?" and "What factors influence the intent of licensed foster parents to continue to foster?" METHOD: A sample of 539 foster parents in eight urban counties in a large Midwestern state completed questionnaires aimed at addressing these questions. RESULTS: Some of the factors exerting the strongest influence on satisfaction were: feeling competent to handle the children who were placed; wanting to take in children who needed loving parents; no regrets about investment in foster children; foster mother's age; and agency social worker providing information and showing approval for a job well done. An example of factors exerting influence on intent to continue to foster include overall satisfaction, readiness to phone the social worker, number of foster boys in the home, being treated like one needed help oneself, and agency affiliation (private). CONCLUSIONS: Efforts to increase the supply of foster homes through recruitment is not enough. The support, training, and professional regard given to parents after they have begun the fostering task is of greater need. Based on analysis of the findings, implications for practice, programming, and policy are offered. 相似文献

Amidst global competition in higher education, colleges and universities adopt strategies that mimic and adapt business practices. Branding is now a widespread practice in higher education; multimodal advertisement is a manifestation of emerging branding strategies for universities. While the visibility of brands in higher education has grown substantially in recent years, its empirical study has lagged. This article reports on the findings from a study that employed social semiotic and multimodal analysis to explore text and visual rhetoric as brand construction strategies in publicly displayed university advertisements. After analyzing photographs representing advertising campaigns from 16 different universities displayed in an urban public transportation system, I suggest that universities construct their brand identity through messages that emphasize multiple choices and convenience, but construct success primarily according to corporate standards and values. 相似文献

There are established links between education and well-being, and between poverty and education. This article draws on interviews with parents of school-aged children impacted by a policy in the UK commonly referred to as the ‘bedroom tax’. A critical psychology perspective to education is put forward, acknowledging the complex interrelationships between psychological well-being, sociopolitical factors and education. 相似文献

Scholarly productivity and the research reputation of academic staff frequently dominate as criteria in the review of higher education courses, disciplines and institutions, a bias which represents a profound hazard for plausible evaluation. Three distinct outcome constructs were identified from analyses of performance indicator data gathered on the accounting discipline in Australia. They were the scholarly productivity of the academic staff involved, the quality of teaching and learning as perceived by students and graduates, and the academic efficiency, in terms of subject completion rates, with which the courses were conducted. Each outcome was shown to be related in a different manner to various characteristics of the courses investigated. The results challenge the orthodox view that scholarly productivity will lead naturally to other desired outcomes of higher education, question the usual surface level interpretation of performance indicators, and suggest that evaluation in higher education might combine connoisseur and performance indicator approaches within the framework of a realist epistemology, placing emphasis on the structures and mechanisms which generate the diverse and distinct outcomes of different courses. 相似文献

For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of statistical tests for deconstructing interaction effects when they are of primary substantive interest. Results indicate the general superiority of the modified Bonferroni procedure over Scheffé and Roy-type procedures, where the Bonferroni and Scheffé procedures have been modified to accommodate the logical implications of a false omnibus interaction null hypothesis. An applied example is provided and considerations for applied researchers are offered. 相似文献

This study highlights the longitudinal changes in educational attitudes of students during the freshman year of college, with the prime focus on comparisons between students in a living-learning program (N=95) and students in the regular curriculum (N=89) at the University of California, Davis. The Student Orientations Survey was used in a pre-post design, and major results were (1) students who selected the experimental program held somewhat different attitudes from their peers in the regular curriculum prior to the start of the academic year and (2) compared to changes in attitudes of their peers, the experimental-program students, by the end of the academic year, had significantly decreased their desire for lectures and formalized education, expressed greater interest in self-directed independent study, desired a more significant role in educational decision-making, and viewed education more as a way of exploring various academic areas rather than solely preparing for a vocational future. Coupled with findings from student interviews, various implications of the results were discussed. 相似文献
