The Nonverbal Literacy Assessment (NVLA) is a literacy assessment designed for students with significant intellectual disabilities. The 218‐item test was initially examined using confirmatory factor analysis. This method showed that the test worked as expected, but the items loaded onto a single factor. This article uses item response theory to investigate the NVLA using Rasch models. First, we reduced the number of items using a unidimensional model, which resulted in high levels of test reliability despite decreasing the number of questions, providing the same information about student abilities in less time. Second, the multidimensional analysis indicated that it is possible to view the NVLA as a test with four dimensions, resulting in more detailed information about student abilities. Finally, we combined these approaches to obtain both specificity and brevity, with a four‐dimensional model using 133 items from the original NVLA. 相似文献

In this study, counselor educators responded to a survey about their scholarly productivity over a 3‐year period. Their involvement in 7 scholarly activities is reported by category and by type of institution, tenure status, academic rank, and gender. Using a more comprehensive definition of scholarly productivity, this study documents that counselor educators are involved in a much broader, more diversified spectrum of scholarly activities than prior studies of scholarly productivity have indicated. Implications for tenure and promotion decisions, along with recommendations for training and mentoring of future counselor educators as well as future directions for research, are discussed. 相似文献

The effects of college tuition costs on early career educational, occupational and economic achievements were estimated for a national sample of black and white college students. The findings suggest that attending a relatively high tuition college has a net positive influence on such outcomes as educational attainment, occupational status, income and women's entry into sex-atypical careers. These effects remained significant even when controls were made for student background characteristics (e.g., socioeconomic origins, secondary school achievement, educational and occupational aspirations); the academic selectivity, private/public control, size and graduate orientation of the college attended; and one's specific college experiences (e.g., academic major, academic achievement and social involvement). The findings are discussed in terms of several plausible causal mechanisms. 相似文献

An assessment was undertaken of the attitudes of individuals within the science community towards a program to produce genetically modified cattle for altered milk composition, expectantly allowing for research into the treatment of multiple sclerosis in humans. The majority of respondents to an electronic survey expressed favorable attitudes to the program, thought it beneficial, respected individual freedom and was fair and just and disagreed that it was harmful. A passion for science and having a suitable lifestyle were the most important motivating factors for individuals. Finally, there were a wide range of responses to a number of cultural beliefs or myths. Science grouping significantly affected the responses. Compared with Systems and Land groups, Plant and Reproduction groups more strongly agreed with the project, thought it less harmful to interest groups, felt that genetic modification of animals was more morally acceptable, and more strongly agreed with the myth statements. These results indicate a diversity of beliefs and attitudes towards genetic modification amongst those within the science community, and highlight the importance of understanding ethics and myths in dealing with them. It is suggested that the diversity of beliefs could be better used to help shape public policy and understanding of biotechnology. 相似文献

This editorial paper outlines key directions for knowledge management research and practice. The editorial team presents the results from a small survey of academics and practitioners about the present and future of knowledge management, and the editors include their own informed views on how this journal can help promote scholarly inquiry in the field. 相似文献

This paper estimates the effects of various college qualities on several early adult outcomes, using panel data from the National Education Longitudinal Study. I compare the results using ordinary least squares with three alternative methods of estimation, including instrumental variables, and the methods used by Dale and Krueger [(2002). Estimating the payoff to attending a more selective college: An application of selection on observables and unobservables. Quarterly Journal of Economics, 117(4), 1491–1528.] and Black and Smith [(2004). How robust is the evidence on the effects of college quality? Evidence from matching. Journal of Econometrics, 121, 99–124.]. I find that college quality does have positive significant effects on most outcomes studied using OLS. While there is some evidence of positive selection bias in the OLS results, the alternative methods rarely produce findings that are significantly different from the OLS estimates. Furthermore, alternative methods have their own limitations, which are discussed. Across methods of estimation, there is solid evidence of positive effects of college quality on college graduation and household income, and weaker evidence of effects on hourly wages. 相似文献
