Prolog programming techniques

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language.     

University research in flux: Policy debate in Australia

After a brief golden age Australian university research faces a difficult future. Two notions, utility and concentration, have become the catchwords of the emerging policy initiatives. Both have tended to be interpreted narrowly and simplistically, utility as having immediate technological applications that will bring economic benefits, and concentration to argue for breaking the teaching-research nexus, reducing the research workforce and thus achieving cost savings. As proposed, both initiatives require more centralised control of research policy and funding. Despite the outstanding record of Australia's universities in research and the absence of evidence to support the benefits claimed for the new initiatives, the pressure for change is gaining momentum. The problems facing Australian universities have much in common with those in other Western countries, although unique solutions must be sought for every setting. This paper argues that, in Australia, the adoption of the easy solution of increased concentration, short-term utility, and centralised control, is likely to compromise the established excellence and diversity in basic research, and to lead to an overall reduction in the scale of university research. Before any changes are instigated, there is a pressing need for a broad-ranging review based on widespread participation in a debate about needs and priorities, and rigorous research into the performance of the existing system and the potential benefits of the changes proposed.     

Factors contributing to preservice teachers' management of children's problem behaviors

The purpose of this study was to assess factors that contribute to preservice teachers' choice of a helping or a restrictive strategy to manage social immaturity and social defiance behaviors among children. Levels of tolerance, opinions as to the causes of behavior, perceptions of adverse effects or costs of problem behaviors, and choice of strategy were measured in response to hypothetical samples of problem behavior. Regression analyses indicated that the costs of problem behavior significantly predicted the type of strategy that would be chosen. Training preservice teachers to manage these costs was the main implication for teacher training programs.     

Analyzing a service-learning experience using a social justice lens

This mixed methods study explores a service-learning experience embedded in a social foundations course in a teacher education program. The authors differentiate learning outcomes for social justice and charity service-learning, and utilize this framework to examine whether the service-learning experience fosters a social justice perspective. The findings demonstrate that while the experience did foster social justice perspectives for some students, the data also reflect evidence of learning outcomes that align with charity service-learning.
