Secondary School Art Teachers' Concepts of Teaching in Hong Kong

Recently, there has been considerable concern among art educators and cultural policy makers to promote art education in Hong Kong. The launch of the new curriculum of a discipline-based character in 1996 generated debate in the art education circle of Hong Kong. There were diverse opinions on the rationale for teaching art. Concern was expressed about the present constraints of art teaching related to teachers' ability and school administration poses another important issue that seems to inhibit further developments. This paper reports part of the findings of a study on art teachers' concepts of teaching. It explores the concepts of about 20 secondary art teachers in Hong Kong. Several categories of teaching are derived from interviews: aesthetic development, moral development, intellectual development, expression and therapy, and intellectual and aesthetic development. A scheme is developed which can be used to analyze teachers' concepts as education in or through art on a continuum from subject to learner centred.     

Locating Self in the World: Elementary school children in Japan,Macau and Hong Kong

In the so-called 'global age', the issue of how children learn to locate themselves in the world is an important one. Working from a foundation of theories related to globalisation, identity development and citizenship education, this paper describes the findings of a research project which explored elementary school children's geographical and affective location of the self in Japan, Macau and Hong Kong. Analysis and discussion of Japanese education policy is then presented in an attempt to explain the finding that Japanese children are far less likely than their counterparts in Hong Kong and Macau to locate themselves in an international sphere.     

Dielectrophoretic manipulation of particles in a modified microfluidic H filter with multi-insulating blocks

The conventional microfluidic H filter is modified with multi-insulating blocks to achieve a flow-through manipulation and separation of microparticles. The device transports particles by exploiting electro-osmosis and electrophoresis, and manipulates particles by utilizing dielectrophoresis (DEP). Polydimethylsiloxane (PDMS) blocks fabricated in the main channel of the PDMS H filter induce a nonuniform electric field, which exerts a negative DEP force on the particles. The use of multi-insulating blocks not only enhances the DEP force generated, but it also increases the controllability of the motion of the particles, facilitating their manipulation and separation. Experiments were conducted to demonstrate the controlled flow direction of particles by adjusting the applied voltages and the separation of particles by size under two different input conditions, namely (i) a dc electric field mode and (ii) a combined ac and dc field mode. Numerical simulations elucidate the electrokinetic and hydrodynamic forces acting on a particle, with theoretically predicted particle trajectories in good agreement with those observed experimentally. In addition, the flow field was obtained experimentally with fluorescent tracer particles using the microparticle image velocimetry (μ-PIV) technique.     

Improvement of rectification effects in diffuser/nozzle structures with viscoelastic fluids

This paper reports the improvement of rectification effects in diffuser∕nozzle structures with viscoelastic fluids. Since rectification in a diffuser∕nozzle structure with Newtonian fluids is caused by inertial effects, micropumps based on this concept require a relatively high Reynolds numbers and high pumping frequencies. In applications with relatively low Reynolds numbers, anisotropic behavior can be achieved with viscoelastic effects. In our investigations, a solution of dilute polyethylene oxide was used as the viscoelastic fluid. A microfluidic device was fabricated in silicon using deep reactive ion etching. The microfluidic device consists of access ports for pressure measurement, and a series of ten diffuser∕nozzle structures. Measurements were carried out for diffuser∕nozzle structures with opening angles ranging from 15° to 60°. Flow visualization, pressure drop and diodicity of de-ionized water and the viscoelastic fluid were compared and discussed. The improvement of diodicity promises a simple pumping concept at low Reynolds numbers for lab-on-a-chip applications.     

Development of a Questionnaire to Measure the Level of Reflective Thinking

Many courses aim to promote reflective thinking or reflection upon practice, but there is a scarcity of readily usable instruments to determine whether students engage in reflective thinking and, if so, to what extent. This paper reports the development and testing of such an instrument. To ensure validity, the constructs measured were derived from the extensive literature on reflective thinking, particularly the writing of Mezirow. A combination of the literature review and initial testing led to the development of a four-scale instrument measuring four constructs; habitual action, understanding, reflection and critical reflection. The final version of the instrument was tested with a sample of 303 students from eight classes of a health science faculty. The reliability of the scales was established by acceptable Cronbach alpha values. Confirmatory factor analysis showed a good fit to the proposed four-factor structure. Comparison of mean scores between the eight classes showed predicted significant differences on each of the four scales between undergraduate and postgraduate students.
