Developing key concepts in physics : Is it more effective to teach using scientific visualizations?

A quantitative, quasi-experimental study of the effectiveness of computer-based scientific visualizations for concept learning on the part of Year 11 physics students (n=80) was conducted in six Queensland high school classrooms. Students’ gender and academic ability were also considered as factors in relation to the effectiveness of teaching with visualizations. Learning with visualizations was found to be equally effective as learning without them for all students, with no statistically significant difference in outcomes being observed for the group as a whole or on the academic ability dimension. Male students were found to learn significantly better with visualizations than without, while no such effect was observed for female students. This may give rise to some concern for the equity issues raised by introducing visualizations. Given that other research shows that students enjoy learning with visualizations and that their engagement with learning is enhanced, the finding that the learning outcomes are the same as for teaching without visualizations supports teachers’ use of visualizations.

Renewing undergraduate IT education

Information Technology (IT) education is in crisis. Enrolments have dropped by up to as much as 70% at some universities (Markoff, 2009). This coupled with traditionally high attrition and failure rates (Biggers et al, 2008) is resulting in the number of graduates nationwide being far lower than industry demand (Queensland Government SkillsInfo Report, 2009). This work reports on a radical redesign of the Bachelor of IT degree at QUT. The initial results are very promising with attrition in first year dropping from being one of the highest at QUT for an undergraduate degree to being one of the lowest. The redesign followed an action research model to reflect on issues and problems with the previous version of the degree and to introduce changes to attempt to rectify some of these problems. The resulting degree intends to produce "business savvy" graduates who are capable of using their IT knowledge and skills within cross-functional teams to solve complex problems.

Charitable grants and donations from maching gaming sources : Does it all work out in the wash up?

Material for this paper comes partly from a report commissioned by the Department of Family Services, Aboriginal and Islander Affairs. The report is the result of a multi-strategy research project designed to assess the impact of gaming machines on the fundraising capacity of charitable and community organisations in Queensland. The first Queensland gaming machine was commissioned on 11 February 1992. By 30 November 1994 there were: · 636 clubs operating 13,162 gaming machines · 436 hotels/taverns operating 3,468 gaming machines.1 It was anticipated that the introduction of gaming machines would impact on charities and community organisations. The adverse impacts would be through competition with charity gaming and disposable income that might otherwise be directed towards donations. Some also expressed concern that charities would be relied on to finance social services for problem gamblers. This paper seeks to describe the donations and grants derived by charities from Gaming Machine revenues. Such revenues primarily come from either government distributions from its gaming machine taxes and levies or gaming machine club donations. A final comment is made on the opinions of charitable fundraising professionals about the impact of gaming machine levies on club donations.

An exploratory study into audit challenges in IT governance : a Delphi approach

Information technology (IT) has been playing a powerful role in creating a competitive advantage for organisations over the past decades. This role has become proportionally greater over time as expectations for IT investments to drive business opportunities keep on rising. However, this reliance on IT has also raised concerns about regulatory compliance, governance and security. IT governance (ITG) audit leverages the skills of IS/IT auditors to ensure that IT initiatives are in line with the business strategies. ITG audit emerged as part of performance audit to provide an assessment of the effective implementation of ITG. This research attempts to empirically examine the ITG audit challenges in the Australian public sector. Based on literature research and Delphi research, this paper provides insights regarding the impact of, and required effort to address these challenges. The authors also present the ten major ITG audit challenges facing Australian public sector organisations today.

Nonprofits and the GST : don't sign anything until you've read the fine print, (if you can find it to read!)

On 13 August, 1997 Prime Minister Mr Howard announced five principles as a foundation for a Tax Reform Package to revitalise the Australian economy. They were that: 1. there should be no overall increase in the overall tax burden; 2. any new taxation system should involve major reductions in personal income tax with special regard to the taxation treatment of families; 3. consideration should be given to a broad-based indirect tax to replace some or all of the existing indirect taxes; 4. there would be appropriate compensation for those deserving of special consideration; and 5. reform of Commonwealth-State financial relations must be addressed...

Teamwork in first year law units : can it work?

Since the 1980s, higher education in Australia has undergone significant change which has led to the belief that universities should cultivate students’ generic skills and attributes. For example, Achieving Quality states that generic skills ‘should represent the central achievements of higher education as a process’ (Higher Education Council, 1992, p 20). The CALD Standards for Australian Law Schools also recognise that tertiary curricula should ‘seek to develop knowledge, understanding, skills, and values’ (Council of Australian Law Deans, 2009, [2.3]. See also AQF Council, 2010, pp 32-5, 40-2; AQF Council, 2011, p 45-50). This more instrumentalist view of education is similarly exhibited by students (Saulwick and Muller, 2006, pp 7, 34). No longer does the modern graduate expect their university degree to equip them solely with the content knowledge of their discipline, but also with the skills and attributes relevant to their career and prospective employment.

What would it take to optimise young people’s sexual health? A conversational journey with youth workers

Marginalised young people have been consistently identified as a high risk group in relation to sexual health. This research, undertaken through the Youth Affairs Network of Queensland, seeks to explore impacts on youth workers’ ability to provide effective interventions around sexual health? What knowledge,skills, resources, value and ethics, training and support is available to youth workers? What do youth workers identify that they need and what workforce development strategies are recommended to enable the youth sector to respond more effectively? This project report provides a snapshot and introduction to the key themes raised by youth workers and other key stakeholders in Queensland Australia.

'It ain't over till it's over' : Yogi Berra bias on prediction markets

The recent expansion of prediction markets provides a great opportunity to test the market efficiency hypothesis and the calibration of trader judgements. Using a large database of observed prices, this article studies the calibration of prediction markets prices on sporting events using both nonparametric and parametric methods. While only minor bias can be observed during most of the lifetime of the contracts, the calibration of prices deteriorates very significantly in the last moments of the contracts’ lives. Traders tend to overestimate the probability of the losing team to reverse the situation in the last minutes of the game.
