Students as decoders of graphics in mathematics

This paper reports on students’ ability to decode mathematical graphics. The findings were: (a) some items showed an insignificant improvement over time; (b) success involves identifying critical perceptual elements in the graphic and incorporating these elements into a solution strategy; and (c) the optimal strategy capitalises on how information is encoded in the graphic. Implications include a need for teachers to be proactive in supporting students’ to develop their graphical knowledge and an awareness that knowledge varies substantially across students.

Solving graphics tasks : gender differences in middle-school students

The capacity to solve tasks that contain high concentrations of visual-spatial information, including graphs, maps and diagrams, is becoming increasingly important in educational contexts as well as everyday life. This research examined gender differences in the performance of students solving graphics tasks from the Graphical Languages in Mathematics (GLIM) instrument that included number lines, graphs, maps and diagrams. The participants were 317 Australian students (169 males and 148 females) aged 9 to 12 years. Boys outperformed girls on graphical languages that required the interpretation of information represented on an axis and graphical languages that required movement between two- and three-dimensional representations (generally Map language).

What health services within rural communities tell us about Aboriginal people and Aboriginal health

There is a growing body of literature within social and cultural geography that explores notions of place, space, culture, race and identity. When health services in rural communities are explored using these notions, it can lead to multiple ways of understanding the cultural meanings inscribed within health services and how they can be embedded with an array of politics. For example, health services can often reflect the symbolic place that each individual holds within that rural community. Through the use of a rural health service case study, this paper will demonstrate how the physical sites and appearances of health services can act as social texts that convey messages of belonging and welcome, or exclusion and domination. They can also produce and reproduce power and control relations. In this way, they can influence the ways that Aboriginal people engage in health service environments – either as places where Aboriginal people feel welcome, comfortable, secure and culturally safe and happy to use the health service, or as places where they utilise the service provided with a great deal of effort, angst and energy. It is important to understand how these complex notions play out in rural communities if the health and wellbeing of Aboriginal people is going to be addressed.

Merging fact with fiction : a study of year 9 students' developing scientific literacy through the writing of hybridised scientific narratives on a socioscientific issue

International assessments of student science achievement, and growing evidence of students' waning interest in school science, have ensured that the development of scientific literacy continues to remain an important educational priority. Furthermore, researchers have called for teaching and learning strategies to engage students in the learning of science, particularly in the middle years of schooling. This study extends previous national and international research that has established a link between writing and learning science. Specifically, it investigates the learning experiences of eight intact Year 9 science classes as they engage in the writing of short stories that merge scientific and narrative genres (i.e., hybridised scientific narratives) about the socioscientific issue of biosecurity. This study employed a triangulation mixed methods research design, generating both quantitative and qualitative data, in order to investigate three research questions that examined the extent to which the students' participation in the study enhanced their scientific literacy; the extent to which the students demonstrated conceptual understanding of related scientific concepts through their written artefacts and in interviews about the artefacts; and the extent to which the students' participation in the project influenced their attitudes toward science and science learning. Three aspects of scientific literacy were investigated in this study: conceptual science understandings (a derived sense of scientific literacy), the students' transformation of scientific information in written stories about biosecurity (simple and expanded fundamental senses of scientific literacy), and attitudes toward science and science learning. The stories written by students in a selected case study class (N=26) were analysed quantitatively using a series of specifically-designed matrices that produce numerical scores that reflect students' developing fundamental and derived senses of scientific literacy. All students (N=152) also completed a Likert-style instrument (i.e., BioQuiz), pretest and posttest, that examined their interest in learning science, science self-efficacy, their perceived personal and general value of science, their familiarity with biosecurity issues, and their attitudes toward biosecurity. Socioscientific issues (SSI) education served as a theoretical framework for this study. It sought to investigate an alternative discourse with which students can engage in the context of SSI education, and the role of positive attitudes in engaging students in the negotiation of socioscientific issues. Results of the study have revealed that writing BioStories enhanced selected aspects of the participants' attitudes toward science and science learning, and their awareness and conceptual understanding of issues relating to biosecurity. Furthermore, the students' written artefacts alone did not provide an accurate representation of the level of their conceptual science understandings. An examination of these artefacts in combination with interviews about the students' written work provided a more comprehensive assessment of their developing scientific literacy. These findings support extensive calls for the utilisation of diversified writing-to-learn strategies in the science classroom, and therefore make a significant contribution to the writing-to-learn science literature, particularly in relation to the use of hybridised scientific genres. At the same time, this study presents the argument that the writing of hybridised scientific narratives such as BioStories can be used to complement the types of written discourse with which students engage in the negotiation of socioscientific issues, namely, argumentation, as the development of positive attitudes toward science and science learning can encourage students' participation in the discourse of science. The implications of this study for curricular design and implementation, and for further research, are also discussed.

Nurturing Needs: Literacy Achievement for Refugee students

Yeronga State School, located 7 km from the city in Brisbane, Queensland, opened in 1871. YSS caters for a middle class inner-suburban community, however, from the mid 1990s enrolments brought new forms of socio-economic, cultural and linguistic diversity. Initially, ESL students were enrolled due to their immigrant parents enrolling in the neighbouring TAFE. Then refugee families from Bosnia and the Middle East became part of the YSS community. In recent years, refugee numbers have accounted for up to 23% of the school population. Many of these new arrivals left behind families in war-torn circumstances, were orphaned or came to live with unknown relatives. Some family members were victims of torture which may have been witnessed by the children. Trauma for some or all family members was a very real concern. Others were born in refugee camps, where food was scarce, belongings needed to be guarded and safety was never guaranteed.

Rural Poultry in the Developing world

In 2007 I travelled to Mozambique and Tanzania to photographically document the work undertaken by a group of Australians who are working to bring a self sufficient lifestyle back to the HIV Aids stricken communities of Africa. University of Queensland veterinary researchers have developed a vaccination that can eradicate disease from local rural poultry. The Kyeema Foundation is working in country to supply this vaccine to families battling HIV AIDS and to teach local residents how to successfully implement it. QUT, AusAID and the Kyeema Foundation funded the trip.
