Adaptation and validation of the Course Experience Questionnaire in the context of post-secondary education in Hong Kong

Purpose – The Course Experience Questionnaire (CEQ) is a quantitative instrument for collecting student feedback on programme quality that has been tested and practically used in Western university response-contexts. The purpose of this paper is to adapt and partially validate a Chinese translation of the CEQ, for application in the new context of post-secondary education in Hong Kong. Design/methodology/approach – From a population of about 2,515 students in six institutions, 1,572 responses were obtained, representing a response rate of 62.5 percent. Given that a Chinese CEQ has never been tested in this new context, an exploratory approach was adopted by examining the psychometric properties of the CEQ constituent scales and their underlying factor structure as exhibited via item-correlation analysis and exploratory factor analysis. Findings – The alpha values of the CEQ scales in the present study are generally lower than those of the other reported studies. The results of exploratory factor analysis indicate that the degree of overlap among the constructs as measured by the CEQ scales is more extensive than most other reported studies, resulting in only four factors being explicitly indicated, with some constructs being overshadowed by other more salient constructs and failing to exhibit in the factor structure. Practical implications – While broadly supporting the potential of CEQ-type surveys in informing the quality endeavour, the findings of the present study (and those of some related tests on Chinese students that have recently been reported) suggest the need for further development of the CEQ for application in the Chinese context in general, and the context of Hong Kong post-secondary education in particular. Originality/value – The paper cross-validates the CEQ in a new context

Adaptation and validation of the Inventory of Learning Styles for quality assurance in a Hong Kong post-secondary education context

A Chinese translation of the Inventory of Learning Styles (ILS), a quantitative instrument employed mainly in Western higher education contexts for collecting students' feedback on their learning patterns (in the form of students' processing strategies, regulation strategies, learning orientations and conceptions of learning), was adapted and validated for application in the new response-context of Hong Kong post-secondary education via a large student sample. The reliabilities of the adapted ILS scales, as reflected by Cronbach's coefficient alphas, were found to be generally satisfactory. From an exploratory factor analysis conducted on the adapted ILS scales, four factors were identified that resemble the relevant features of the factor structure reported in a study in an Indonesian response-context. Overall, the present study provides qualified support for the reliability and validity of the adapted ILS for application in the context of Hong Kong post-secondary education

Recent achievements in facilitated transport membranes for separation processes

Membrane separation processes have been extensively used for some important industrial separations, substituting traditional methods. However, some applications require the development of new membranes. In this work, we discuss recent progress achieved in this field, focusing on gas and liquid separation using facilitated transport membranes. The advantages of using a carrier species either in a liquid membrane or fixed in a polymer matrix to enhance both the flux and the selectivity of the transport are summarized. The most probable transport mechanisms in these membranes are presented and the improvements needed to spread this technology are also discussed. As examples, we discuss our very successful experiences in air fractioning, olefin/paraffin separation and sugar recovery using liquid and fixed carrier membranes
