Exploring the Meanings of Hijab through Online Comments in Canada

Controversies surrounding ethnic dress such as hijab have increased public awareness about cultural diversity. The number of comments posted on online media make it evident that many people are concerned about ethnic attire, cultural differences and social cohesion. Although researchers have examined the meanings of veiling, the relationships between hijab and public opinion have seldom been investigated. The overarching objective of this study was to understand the relationships between Islamic attire and online readers’ opinion. In light of the limitations in the previous studies on this topic, this study attempts to fill the gap by studying posters’ opinions toward hijab through publicly available online information in the form of posted comments.     

The Use and Effectiveness of Palmtop Computers in Education

This paper reports how palmtop computers were used in an English secondary school over the course of a year. In particular, it concentrates on the perceived effectiveness of such computers in an educational setting, and on how teachers' and students' knowledge and use of "content-free" applications increased over that time. The benefits and potential problems with this new technology are discussed along with the consequences it has for classroom and school organisation.     

The role of a professional learning community in teacher change: a perspective from beliefs and practices

This longitudinal study aimed to examine the role of a professional learning community (PLC) in changing teachers’ beliefs and practices. Teachers of a Chinese department in a Hong Kong secondary school were interviewed and observed. The findings indicate that the features of a PLC-facilitating teacher change are development of a coherent structure, a collaborative culture, and effective learning activities. These help teachers to overcome initial difficulties and induce their motivation for transformation. Teacher change in five dimensions (curriculum, teaching, learning, roles of teachers, and learning to teach) and three patterns (change in practice but not in belief, change in belief but not in practice, change in practice and belief) were detected. It is argued that cultivating an effective PLC is significant to teacher development.     

Intra-Asian Cultural Flow: Cultural Homologies in Hong Kong and Japanese Television Soap Operas

This paper examines and theorizes the intra-east-Asian cultural flow of televisual imaginaries between Japan and Hong Kong. With an analysis of survey data, in-depth interviews, and the comparison of soap operas of Hong Kong and Japan in terms of audience interpretation of gender values, marriage, capitalistic relationships, and love, the author illustrates that there is a strong degree of cultural homologies between Japan and Hong Kong and argues that the regional values from Japan have gradually displaced the global culture to become Hong Kong's emancipatory power to resist the control of the state.     

The effect of superfluous information on children's solution of story arithmetic problems

Forty 6- to 7-year-old children were tested with single-step, addition/subtraction story problems with and without superfluous numerical information. Half of the children were allowed to find out the solution using objects and half were given pen and paper. Fewer problems with superfluous information than those without such information were solved accurately. Less than half of the problems were attempted with spontaneous modelling with objects and rarely were pen and paper used. In many cases, the use of objects could not facilitate solution of problems with superfluous information thus suggesting that in these cases children's failure to solve the problems could not be explained just by an increase in the cognitive demand for selective attention to, and memory of, the relevant information.     

An overview of Prolog debugging tools

In this paper we present an overview of the advances in debugging standard Prolog programs. The analysis offered is in terms of a classification of tools that provide different degrees of activity in the debugging process. Other possible dimensions of analysis are also outlined.     

Software that assists learning within a complex abstract domain: the use of constraint and consequentiality as learning mechanisms

This paper describes a research project into undergraduates’ use of a software tool to learn symbolic logic—a complex abstract domain that has been shown to be intimidating for students. The software allows the students to manipulate proofs in certain ways and then calculates the consequences of their actions. A research method has been developed that allowed students’ use of this tool to be modelled, and this model was then used to identify, refine and create visual cues that provide support for students’ reasoning. The focus of this paper is the role of the software as an artefact to aid students’ visualisation of reasoning processes rather than the logic itself. The main mechanisms by which this visualisation is supported are the imposition of constraints on the actions available and the demonstration to students of the consequences of their actions. The study shows that the software encouraged experimentation with different routes to a proof, and constituted a challenge to fixated reasoning.     

Managing Element Interactivity in Equation Solving

Between two popular teaching methods (i.e., balance method vs. inverse method) for equation solving, the main difference occurs at the operational line (e.g., +2 on both sides vs. ?2 becomes +2), whereby it alters the state of the equation and yet maintains its equality. Element interactivity occurs on both sides of the equation in the balance method, but only on one side in the case of the inverse method. Thus, the balance method imposes twice as many interacting elements as the inverse method for each operational line. In two experiments, secondary students were randomly assigned to either the balance method or the inverse method to learn how to solve one-step, two-step, and three-or-more-step linear equations. Test results indicated that the interaction between method and type of equation favored the inverse method for equations involving higher element interactivity. Hence, by managing element interactivity, the efficiency of instruction for equation solving can be improved.
