ITEM-EXAMINEE SAMPLING PROCEDURES AND ASSOCIATED STANDARD ERRORS IN ESTIMATING TEST PARAMETERS

Selected parameters for a negatively skewed and a normally distributed normative distribution were estimated in a post mortem item-examinee sampling investigation. Manipulated systematically were number of subtests, number of items per subtest, and number of examinees responding to each sub-test. Each item-examinee sampling procedure was replicated five times. Defining one observation as the score received by one examinee on one item, the results of this investigation support the conclusion that, in estimating parameters by item-examinee sampling, the variable of importance is not the item-examinee sampling procedure but is instead the number of observations obtained by that procedure. Degree of skewness in the normative distribution and failure to distribute all items among subtests were found to be relatively unimportant variables.     

Towards a Transformative Epistemology of Technology Education

Technology Education offers an authentic and invaluable range of skills, knowledge, capabilities, contexts and ways of thinking for learners in the 21^st century. However, it is recognised that it occupies a comparatively less defined and more fragile curricular position than associated, but longer established, subjects such as Mathematics and Science. While recognising that no single factor lies behind such a condition, this paper draws upon thinking in the philosophy of technology, technology education and the ontology of artefacts to argue that transformation may be considered as an epistemic source for technology in a similar way to ‘proof’ within Mathematics and ‘interpretation’ within Science. Encapsulating technology's intimate relationship with materials, it is ultimately argued that the transformation of a technical artefact from an ill‐defined into a well‐defined ontological state constitutes a prime source of technological knowledge for pupils. Moreover, it provides an alternative route into further consideration about the nature of the domain, epistemology and curricular identity of the subject.     

Hong Kong Higher Education, 1981–2001: public policy and re-emergent social stratification

In this paper I first place the development of Hong Kong's higher education in the larger context of education and governance histories. Next I describe one of the deepest policy quandaries for Hong Kong's government in charting the futures of its higher education system: whether to view the ultimate benefits of higher education for individuals in terms of ‘sponsored’ versus ‘contest’ mobility. I then turn to evidence from HK census data about the changing distribution of opportunity for higher education. I discuss trends in educational stratification since 1981, focusing most attention on changes in the opportunity for post-secondary and, especially, for university education to the Bachelors' degree level. I discuss methods for the use of Hong Kong's 1981, 1991 and 2001 census, and I present bivariate and multivariate analysis of the changing impact of family cultural and material resources on the odds of continuing and attending education at the university level. From 1991 to 2001, census data suggest there was a reversal of a trend towards greater equality of opportunity that was observed between the 1981 and 1991 census. I conclude by relating the findings from these analyses to future higher education planning in Hong Kong.
