In Support of Pair Programming in the Introductory Computer Science Course

A formal pair programming experiment was run at North Carolina to empirically assess the educational efficacy of the technique in a CS1 course. Results indicate that students who practice pair programming perform better on programming projects and are more likely to succeed by completing the class with a C or better. Student pairs are more self-sufficient which reduces their reliance on the teaching staff. Qualitatively, paired students demonstrate higher order thinking skills than students who work alone. These results are supportive of pair programming as a collaborative learning technique.     

Community attitudes towards broadcasting standards in New Zealand

In this article we report on the findings of a 1999 research project conducted by New Zealand's Broadcasting Standards Authority (the Authority). The project was designed to survey the attitudes of New Zealand adults to several aspects of broadcasting standards, such as offensive language, screen violence, the portrayal of sex and nudity, discrimination and privacy issues. This article will examine the background to the research, the principal empirical findings, and in conclusion will identify five cluster profiles which emerged from a statistical analysis of the data.     

Using Story to Help Student Understanding of Gas Behavior

Students tend to have a poor understanding of the concept of gas pressure. Usually, gas pressure is taught in terms of the various formulaic gas laws. The development of the concept of gas pressure according to the early Greeks did not include the concept of a vacuum. It was not for another 2000 years that Torricelli proposed that a vacuum can exist and that he was able to produce a vacuum above a column of mercury. However, the existence of a vacuum continued to be a contentious issue for at least another 100 years. During this time the behavior of gases was studied by Boyle, Amontons, Gay-Lussac, Daniel Bernouli, Charles, and Dalton. In the 19^th century gas behavior was revisited and studied from the molecular level through the work of Graham, Maxwell, Boltzmann, and van der Waal. The stories of conflicting theories and the development of the concept of gas pressure gives students an increased appreciation for the nature of science and helps them with conceptual understanding of the concept of gas pressure.     

Techno therapy or nurtured niches? Technology studies and the evaluation of radical innovations

This article contributes to recent discussions in technology studies about applying insights from technology studies to policy decisions about the development and management of technological innovations. It does so by examining two approaches that can be used by policy makers to manage radical technological innovations in mobility and transportation: strategic niche management (SNM) and the PROTEE approach. The SNM approach uses protective ‘niches’ to develop radical innovations, whereas the PROTEE method is grounded in the assumption that technological innovations have a better chance of success if made “vulnerable” by subjecting them to risks and oppositions from the outset. Both SNM and PROTEE have, so far, been applied to retrospective case studies. This paper examines their potential effectiveness in the monitoring of real time innovation projects by comparing their conceptualizations of ‘learning’ and ‘experimenting’. It argues that the two approaches can draw upon each other to achieve a more refined conceptualization of learning and experimenting and in dealing with the problem of change and obduracy in the development of innovation projects.
