This study demonstrates how case study research can be used to do a contextual and inductive study of information literacy (IL) and develop robust models of IL. First, it identifies several key characteristics of case study research as a qualified research methodology for studies that aim to build theories. Second, it rationalizes a need for case study research in the field of IL research. Drawing on that, it demonstrates how Eisenhardt's case study process was adopted to conduct a contextual study of IL and discusses the researcher's activities and tasks in each phase of the process. It uses the researcher's experience of the research journey to justify the validity and robustness of the research. This article contributes to current IL research methodologies and can be of value for LIS researchers and practitioners who wish to holistically gain deep insight into phenomena through case study research. 相似文献

This research was initiated to explore the effects of changing tuition rates on the open‐door policy of U.S. community junior colleges. Tuition trends in the two‐year colleges of 50 states were assessed using data gathered from the 1975 and 1980 editions of the AACJC Directory, 1980 Fact Book for Academic Administrators, and recently published journal articles. The relationship between tuition rates and enrollment levels in each state were analyzed. The analyses point to a trend of continuous increase in tuition rates for U.S. public two‐year colleges since 1951. Even though the percentage of increase in tuition for recent years has been higher for two‐year colleges than for four‐year colleges, there remains a substantial difference between the average annual tuition of the two types of institutions. There appears to be a negative correlation between tuition and enrollment at two‐year colleges for 1974‐1975 (—.27) and for 1979‐1980 (—.21). Based on these findings, it would appear that further increases in tuition might serve to close college doors for those not able to afford the rising costs of education. Suggestions are offered for internal and external actions to help maintain open access despite rising tuition costs. 相似文献

Swarm intelligence approaches, such as ant colony optimization (ACO), are used in adaptive e-learning systems and provide an effective method for finding optimal learning paths based on self-organization. The aim of this paper is to develop an improved modeling of adaptive tutoring systems using ACO. In this model, the learning object is personalized based on learning and solving problem styles. The purposed algorithm, based on ACO, generates the adaptive optimal learning path. The algorithm describes an architecture which supports the recording, processing and presentation of collective learner behavior designed to create a feedback loop informing learners of successful paths towards the attainment of learning goals. The algorithm parameters are tuned dynamically to conform to the actual pedagogical process. The article includes the results of implementation and experiment represent this algorithm is able to provide its main purpose which is finding optimal learning paths based on learning styles and improved performance of previous adaptive tutoring systems. 相似文献

Studying everyday life information seeking (ELIS) in a variety of contexts contributes to its conceptual development. The primary goal of this study was to understand ELIS in the context of female university students' coping with daily hassles. To identify the dimensions and determinants of ELIS, and to fill this current gap in the literature, a grounded theory study was conducted using Flick's stages of episodic interviewing with 21 Iranian female first-year university students. Data were collected through semistructured interviews and analyzed through open, axial and selective coding. The findings showed that ELIS in coping with daily hassles is a multidimensional phenomenon that is affected by individuals' characteristics and sociocultural norms and values. Three main categories emerged as determinants of ELIS, namely normative status of the daily hassles, normative status of the information resources, and the individual's characteristics. Two main categories emerged as dimensions of ELIS which were type and strategy of action. Results of this study can contribute to the conceptual development of ELIS and may indicate how and in what circumstances ELIS dimensions emerge. The findings can also be used as a basis for developing information and intervention services in the context of coping with daily hassles. 相似文献

Background and purpose: The perception of aging is one of the independent predictors of functional disability and mortality in the aged ones, this study was conducted to compare the follow-up of a training program with the use of two in-person and telenursing methods on the perception of aging of the elderly, covered by the comprehensive health centers in Ahvaz city.Materials and Methods: This quasi-experimental study involved systematic random sampling conducted on 60 elderly persons (aged 60–75 years) who were referred to in Ahvaz. A training program was conducted for all elderly persons for 3 weeks (three sessions per week), which was accompanied with 2 months of six follow-ups for the telephonic follow-up group (Tele-nursing), and two follow-ups for in-person follow-up group. The data were collected with the use of demographic form, Abbreviated Mental Test (AMT), and The Brief Aging Perceptions Questionnaire (B-APQ). Elderly completed the questionnaire at the beginning of the study and 8 weeks later. The data were subsequently analyzed with SPSS software; and P values less than 0.05 were considered significant.Results: Based on the results, the mean score of perception of aging increased in the study groups after the intervention. This increase was statistically significant only in the intervention group.Discussion and Conclusion: The telephonic follow-up was more effective on Increasing the perception of aging compared with the in-person follow-up. Therefore, using this method is recommended for the elderly. 相似文献
