High school students' perceptions of school science and science careers : a critical look at a critical issue

Disproportionate representation of males and females in science courses and careers continues to be of concern. This article explores gender differences in Australian high school students’ perceptions of school science and their intentions to study university science courses. Nearly 3800 15-year-old students responded to a range of 5-point Likert items relating to intentions to study science at university, perceptions of career-related instrumental issues such as remuneration and job security, self-rated science ability and enjoyment of school science. Australian boys and girls reported enjoying science to a similar extent, however boys reported enjoying it more in relation to other subjects than did girls, and rated their ability in science compared to others in their class more highly than did girls. There was no significant difference between the mean responses of girls and boys to the item “It is likely I will choose a science-related university course when I leave school��� and the strongest predictors of responses to this item were items relating to students’ liking for school science and awareness from school science of new and exciting jobs, followed by their perceived self-ability. These results are discussed in relation to socio-scientific values that interact with identity and career choices, employment prospects in science, and implications for science education.

The influence of school science teachers : the differential importance attributed by males and females to encouragement from science teachers

Research on the achievement and retention of female students in science and mathematics is located within a context of falling levels of participation in physical science and mathematics courses in Australian schools, and underrepresentation of females in some science, technology, engineering and mathematics (STEM) courses. The Interests and Recruitment in Science (IRIS) project is an international project that aims to contribute to understanding and improving recruitment, retention and gender equity in STEM higher education. Nearly 3500 first year students in 30 Australian universities responded to the IRIS survey of 5-point Likert items and open responses. This paper explores gender differences in first year university students’ responses to three questions about important influences on their course choice. The IRIS study found good teachers were rated highly by both males and females as influential in choosing STEM courses, and significantly higher numbers of females rated personal encouragement from senior high school science teacher as very important. In suggestions for addressing sex disparities in male-dominated STEM courses, more females indicated the importance of good teaching/encouragement and more females said (unspecified) encouragement. This study relates to the influence of school science teachers and results are discussed in relation to implications for science education.

Looking back : students' perceptions of the relative enjoyment of primary and secondary school science

This paper reports and discusses a contentious result from an Australia-wide study of the influences on students' decisions about taking senior science subjects. As part of the Choosing Science study (Lyons and Quinn 2010) 3759 Year 10 students were asked to indicate which stage of their schooling (lower primary, upper primary, lower secondary, middle secondary) they had most enjoyed learning science. Crosstabulations of responses revealed that around 78% of students indicated that they had enjoyed learning science more in secondary than in primary school, and 55% enjoyed it the most during Years 9 and 10. The perception that school science was more enjoyable in high school was also found among students who did not intend taking science in Year 11, though to a lesser extent. These findings are unexpected and significant, challenging the prevailing view that enjoyment of school science steadily declines after primary school. The paper elaborates on the findings and suggests that the different conclusions arrived at by studies in this field may be due to the different methodologies employed.

Gender differences in Australian students' relationships with school science

This paper explores issues of gender in Year 10 Australian students‘ experiences of science at school, their self-reported ability in science and their perceptions of science as a subject choice for senior secondary school. A sample of 3759 Year 10 students from across Australia responded to Likert-style questions related to these issues, with findings showing gender differences in perceptions of science, self-rated ability, and reasons for choosing not to study further science. Moreover, interesting contrasts were revealed in patterns of difference of self-rated ability for boys and girls across single-sex and co-educational schools.

A school by any other name...is still a rock band?

How is your academic institution structured? If you work within a university, then no doubt you are familiar with the use of faculties or perhaps colleges. What about departments or schools? Whatever names or structures are employed, how would you describe the working relationship between academics and professional staff members? As a research scientist and academic over the last twenty years, my appointments have almost always been made through academic departments or schools. In each case, the academic unit has been led by a senior academic manager, such as a chair or head, supported by a dedicated team of professional staff. More recently, however, I have had the opportunity of leading an academic discipline and the experience has led me to reflect more broadly about leadership styles and academic structures within the Australian higher education sector. The written record of this reflection was published last year in the Australian Universities Review (Harkin and Healy, 2013), but I’m pleased to be able to provide a brief synopsis here for the readership of Insights.

Anglican boarding school a hotbed of sexual punishment

THE little Anglican boarding school of St Barnabas, in the misty mountain town of Ravenshoe, north Queensland, was allegedly a hotbed of physical and sexual abuse in the 1960s. North Queensland Bishop Bill Ray has confirmed the diocese has few files about the school -- which was closed mid-term in 1990 -- with suspicions they were dumped "down a well or an old mine shaft" in the district A history of brutal physical punishment and sexual abuse at the school dating from the 1960s is now emerging. Headmaster Robert Waddington, who arrived at the school from England to be headmaster in 1961, dished out daily canings to many of his young students and then allegedly raped some behind closed doors in his room or the sick bay, which were next to each other. Former St Barnabas student Bim Atkinson, now 58, and two other former students have levelled allegations against the man they called "the Wadd".

The tertiary debate : a case study analysis of factors considered when applying for university entry by traditional age school leavers in Brisbane

Many interacting factors contribute to a student's choice of a university. This study takes a systems perspective of the choice and develops a Bayesian Network to represent and quantify these factors and their interactions. The systems model is illustrated through a small study of traditional school leavers in Australia, and highlights similarities and differences between universities' perceptions of student choices, students' perceptions of factors that they should consider and how students really make choices. The study shows the range of information that can be gained from this approach, including identification of important factors and scenario assessment.

Choosing science : understanding the declines in senior high school science enrolments

'Choosing Science' reports on the most thorough study yet undertaken in Australia to investigate Year 10 students' decisions about whether to take science subjects. The study was well supported by ASTA members, with around 590 teachers and 3800 students participating. It examined teachers' views on the persistent declines in science enrolments, and students' perceptions of school science and aspirations towards further study and careers. The report discusses students' attitudes to science, their enrolment deliberations, sources of advice and recommendations for change. The report identifies the most likely and unlikely contributors to enrolment declines, and makes 10 recommendations.

Non-response bias in randomized control experiments in criminology : putting the Queensland Community Engagement Trial (QCET) under a microscope

Objectives The goal of this article is to examine whether or not the results of the Queensland Community Engagement Trial (QCET)-a randomized controlled trial that tested the impact of procedural justice policing on citizen attitudes toward police-were affected by different types of nonresponse bias. Method We use two methods (Cochrane and Elffers methods) to explore nonresponse bias: First, we assess the impact of the low response rate by examining the effects of nonresponse group differences between the experimental and control conditions and pooled variance under different scenarios. Second, we assess the degree to which item response rates are influenced by the control and experimental conditions. Results Our analysis of the QCET data suggests that our substantive findings are not influenced by the low response rate in the trial. The results are robust even under extreme conditions, and statistical significance of the results would only be compromised in cases where the pooled variance was much larger for the nonresponse group and the difference between experimental and control conditions was greatly diminished. We also find that there were no biases in the item response rates across the experimental and control conditions. Conclusion RCTs that involve field survey responses-like QCET-are potentially compromised by low response rates and how item response rates might be influenced by the control or experimental conditions. Our results show that the QCET results were not sensitive to the overall low response rate across the experimental and control conditions and the item response rates were not significantly different across the experimental and control groups. Overall, our analysis suggests that the results of QCET are robust and any biases in the survey responses do not significantly influence the main experimental findings.

Optimising the length of Random Breath Tests : results from the Queensland Community Engagement Trial

Research suggests that the length and quality of police-citizen encounters affect policing outcomes. The Koper Curve, for example, shows that the optimal length for police presence in hot spots is between 14 and 15 minutes, with diminishing returns observed thereafter. Our study, using data from the Queensland Community Engagement Trial (QCET), examines the impact of encounter length on citizen perceptions of police performance. QCET involved a randomised field trial, where 60 random breath test (RBT) traffic stop operations were randomly allocated to an experimental condition involving a procedurally just encounter or a business-as-usual control condition. Our results show that the optimal length of time for procedurally just encounters during RBT traffic stops is just less than 2 minutes. We show, therefore, that it is important to encourage and facilitate positive police–citizen encounters during RBTat traffic stops, while ensuring that the length of these interactions does not pass a point of diminishing returns.

School-based youth health nurses and adolescent decision-making concerning reproductive and sexual health advice : how can the law guide healthcare practitioners in this context?

This paper outlines some of the issues faced by School-Based Youth Health Nurses working in Queensland, in relation to the legal principles surrounding the provision of reproductive and sexual health advice. The paper outlines a number of specific issues faced by nurses working within this setting and considers the legal principles underpinning the issues concerning consent and confidentiality. The discussion in this paper demonstrates how the legal principles – which are often viewed as complex and uncertain by nurses working within this field – may be used as a guide to underpin good practice and compliance with the law. Although this paper is considered in the context of nurses working within Queensland, the principles and factors outlined are relevant to healthcare practitioners working within all Australian jurisdictions.

The role of Non-Government Organisations (NGOS) in practising editorial photography in a globalised media environment

The news media industry has changed dramatically into a global business with ever-increasing attention being devoted to entertainment and celebrity across the last 10–20 years. There has also been a growing reliance on images produced by citizens (citizen photojournalism), by media outlets and publishers. It is widely acknowledged that in tandem these changes have shrunk publication opportunities for professional photographers undertaking editorial projects. As a result, photographers are increasingly relying on non-government organisations (NGOs) to gain access to photographing issues and events in developing countries and to expand their economic and portfolio opportunities. This increase in photographers working for and alongside NGOs has given rise to a new genre of editorial photography which I call NGO Reportage. By way of a case study, an exploration of this new genre reveals important issues for photographers working with NGOs and examines the constructed narratives of images contained within these emerging practices.

Accused cleric built reputation at small school in Australia

The little Anglican boarding school of St Barnabas, in the mountain town of Ravenshoe, north Queensland, was where Robert Waddington built his reputation as an educationalist. He was headmaster there from 1961-70, but a growing number of former pupils are now coming forward to say they were subjected to sexual and physical abuse by him. Bim Atkinson, 58, said that his ordeal began after he was sent to the school and joined the choir. “I was absolutely petrified of the man,” Mr Atkinson recalls. “After I joined the choir, the abuse started. He would tell me to go to the sickbay, which had a connecting door to his bedroom and then I would end up in his room.”

Accused cleric link to top music school probe

THE senior Anglican clergyman at the centre of an international child sex scandal was also a governor of a prestigious English music college that is under investigation for the alleged abuse of scores of its students across decades. Robert Waddington, who is alleged to have sexually assaulted students and choirboys in Britain and Australia, was a governor of the scandal-hit Chetham's School of Music for nine years. Waddington recruited students from the school for his choir at Manchester Cathedral, and allegedly abused at least three of the boys until he retired in 1993. The police investigation into the school, which began after the conviction in February of Michael Brewer, a former Chetham's music director, for the sexual abuse of female students, has not previously looked at Waddington. A victim has told The Weekend Australian that he was aware Waddington abused several boys from Chetham's who, like him, had been in the choir. The Cambridge University-educated business analyst, who has offered to give evidence under oath to police and the Church of England's inquiry into Waddington, said the clergyman had kept a collection of pictures in his house of boys he had abused.

Managing and analysing big audio data for environmental monitoring

Environmental monitoring is becoming critical as human activity and climate change place greater pressures on biodiversity, leading to an increasing need for data to make informed decisions. Acoustic sensors can help collect data across large areas for extended periods making them attractive in environmental monitoring. However, managing and analysing large volumes of environmental acoustic data is a great challenge and is consequently hindering the effective utilization of the big dataset collected. This paper presents an overview of our current techniques for collecting, storing and analysing large volumes of acoustic data efficiently, accurately, and cost-effectively.
