The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

The argument of this paper is that there have always been, and still remain, fundamental differences between the purposes of industry and those of higher education. Industry's concern is to make a profit, universities are concerned with open enquiry and intellectual freedom. The values of the two are incommensurable, and it is important that these conflicts of values are not obscured by ambiguity of language or by external pressures.
For more than a decade the British government has sought to increase the competitiveness of industry, and has initiated many changes in universities which it has linked to this policy. Three such developments are critically discussed: the enterprise in higher education initiative, academic audit and assessment of teaching quality and the recent White Paper on fundamental research. It is argued that the tendency of each of these is to cause the merging of business values with those of higher education. If this tendency proceeds unchecked universities will no longer be able to fulfil their vital rôle in a free society - the advancement of new and controversial ideas and the education of their students to think critically and autonomously. 相似文献
