The “new” science specialists

A Victorian government initiative called The Primary Science Specialists Professional Learning Program is designed to tackle students' falling interest in science by investing in the building of teacher capacity. The aims of the initiative are: to improve the science knowledge base of all teachers and therefore increase teachers' capacity to engage students in their learning of science; to increase student interest, aspirations and participation in science and to raise the level of science achievement. The role of the "new" science specialist is not necessarily to teach science to all students, rather to promote science, organise the teaching programs and resources for teaching science and support other teachers in teaching science in their school. The results, to date, show that by creating the role of science specialists in primary schools, and investing in science as a specialised knowledge area, science can be promoted, science teaching resources better managed, and teachers who are not confident in science, mentored. In this way, the impact of promoting and improving the teaching of science can extend from the science specialists to other teachers, to students, the school and the wider community.

A hybrid weighted aggregation method based on consistency and consensus in group decision making

A recent study in Science indicated that the confidence of a decision maker played an essential role in group decision making problems. In order to make use of the information of each individual's confidence of the current decision problem, a new hybrid weighted aggregation method to solve a group decision making peoblem is proposed in this paper. Specifically, the hybrid weight of each expert is generated by a convex combination of his/her subjective experience-based weight and objective problem-domain-based weight. The experience-based weight is derived from the expert's historical experiences and the problem-domain-based weight is characterized by the confidence degree and consensus degree of each expert's opinions in the current decision making process. Based on the hybrid weighted aggregation method, all the experts' opinions which are expressed in the form of fuzzy preference relations are consequently aggregated to obtain a collective group opinion. Some valuable properities of the proposed method are discussed. A nurse manager hiring problem in a hospital is employed to illustrate that the proposed method provides a rational and valid solution for the group decision making problem when the experts are not willing to change their initial preferences, or the cost of change is high due to time limitation.

Gender differences in conference presentations: a consequence of self-selection?

Women continue to be under-represented in the sciences, with their representation declining at each progressive academic level. These differences persist despite long-running policies to ameliorate gender inequity. We compared gender differences in exposure and visibility at an evolutionary biology conference for attendees at two different academic levels: student and post-PhD academic. Despite there being almost exactly a 1:1 ratio of women and men attending the conference, we found that when considering only those who presented talks, women spoke for far less time than men of an equivalent academic level: on average student women presented for 23% less time than student men, and academic women presented for 17% less time than academic men. We conducted more detailed analyses to tease apart whether this gender difference was caused by decisions made by the attendees or through bias in evaluation of the abstracts. At both academic levels, women and men were equally likely to request a presentation. However, women were more likely than men to prefer a short talk, regardless of academic level. We discuss potential underlying reasons for this gender bias, and provide recommendations to avoid similar gender biases at future conferences.

Weaving a web: subaltern consumers, rising consumer culture, and television

Cultivation analysis suggests that television influences local cultures through its complex repertoire of images and narratives, which constitute a representation. Through a discursive analysis of television content in India we contend that rising material aspirations and consumer culture are significantly influenced by this medium. Dialectics of turmoil and tranquility mark this development for the working class population. On the one hand, there is domestication of unrest among subaltern groups, as they withdraw from collective political struggles to narrower and more tranquil forms of emulation and economism. On the other hand, these attempts at emulation have resulted in the poorer sections of society devoting their limited resources to aping a lifestyle well beyond their reach and further compromising their quality of life. The other pole of the dialectic is the increase in turmoil that results from tearing the traditional social fabric and support systems. This turmoil progressively manifests itself in increasing materialism and greater monetization of relationships for these subaltern groups.

Associations between physical activity, television viewing and postnatal depressive symptoms amongst healthy primiparous mothers

Background: Postnatal depression is a serious illness in new mothers. In the general population, physical activity (PA) has been found to reduce the risk of depression, whilst sedentary behaviour (SB; in particular television viewing) has been linked to higher levels of depressive symptoms, yet little is known regarding associations between PA, SB and postnatal depression. This study aimed to investigate associations between PA, television viewing and postnatal depressive symptoms in healthy primiparous mothers.. Methods: Cross-sectional survey data were provided by 406 first-time mothers (approximately 3-months postpartum) enrolled in the Melbourne InFANT Extend trial (2012/2013). Women self-reported PA (time spent walking for leisure and transport, and other moderate and vigorous PA), television viewing, and depressive symptoms (CES-D 10). Random intercept linear models examined associations between PA, television viewing and depressive symptoms. Results: In crude models total PA was inversely associated with risk of postnatal depressive symptoms (B = -0.122; 95% CI = -0.24, -0.01). In models adjusted for key sociodemographic and behavioural covariates the association did not remain statistically significant. No other associations between PA, television viewing and postnatal depressive symptoms were evident.. Conclusions: Postnatal depressive symptoms may not be related to PA and television viewing in the same way that these behaviours predict depressive symptoms in the general population. Further investigation of the specific domains of PA, as well as different types/contexts of SB and their respective associations with postnatal depressive symptoms is warranted in order to better inform development of targeted interventions aimed at enhancing postnatal mental health..

Teacher change in implementing a research developed representation construction pedagogy

The Representations in Learning Science (RiLS) project developed a representation construction approach to teaching and learning in science, which has successfully demonstrated enhanced student learning through sustained engagement with ideas, and enhancement of teachers’ pedagogical knowledge and understandings of how knowledge in science is developed and communicated. The current Constructing Representations in Science Pedagogy (CRISP) project aims at wider scale implementation of the representation construction approach. This paper explores a range of issues that confronted four Year 8 teachers in implementing this research-developed approach, such as: preparedness of the teacher in terms of epistemological positioning and positioning as a learner, significant support for planning and modelling by the university expert, and a team ethos where teachers share ideas and plan jointly. The Year 8 teachers implemented a representation construction approach to the teaching of the topic of astronomy. The Interconnected Model of Teacher Growth (IMTG) (Clarke & Hollingsworth, 2002) was used to analyse the teachers’ experience in planning and delivering the teaching sequence. This model was found to be flexible in identifying the experiences of teachers in different situations and useful in identifying issues for implementation of a research developed pedagogy.

Effect of electronic time monitors on children's television watching: pilot trial of a home-based intervention

OBJECTIVES: This pilot study evaluated the feasibility (recruitment, retention, and acceptability) and preliminary efficacy of a six-week home-based electronic time monitor intervention on New Zealand children's television watching in 2008. METHODS: Twenty-nine children aged 9 to 12 years who watched more than 20 h of television per week (62% male, mean age 10.4 years) were randomised to either the intervention or the control group. The intervention group received an electronic TV time monitor for 6 weeks and advice to restrict TV watching to 1 h per day or less. The control group was given verbal advice to restrict TV watching. RESULTS: Participant retention at 6 weeks was 93%. Semi-structured interviews with intervention families confirmed moderate acceptability of TV time monitors and several perceived benefits including better awareness of household TV viewing and improved time planning. Drawbacks reported included disruption to parents' TV watching and increased sibling conflict. Time spent watching television decreased by 4.2 h (mean change [SD]: -254 [536] min) per week in the intervention group compared with no change in the control group (-3 [241] min), but the difference between groups was not statistically significant, p=0.77. Both groups reported decreases in energy intake from snacks and total screen time and increases in physical activity measured by pedometer and between-group differences were not statistically significant. CONCLUSIONS: Electronic TV time monitors are feasible to use for home-based TV watching interventions although acceptability varies between families. Preliminary findings from this pilot suggest that such devices have potential to decrease children's TV watching but a larger trial is needed to confirm effectiveness. Future research should be family-orientated; take account of other screen time activities; and employ TV time monitors as just one of a range of strategies to decrease sedentary behaviour.

A collaborative autoethnography study to inform the teaching of reflective practice in STEM

The paper explores a collaborative self-study, autoethnography research project, which aided in informing practice for the teaching of reflective practice in Science, Technology, Engineering and Mathematics (STEM) at an Australian university. Self-report methods were used, because it enabled the collection of a variety of self-awareness data generated processes to help produce insights and understandings. This was achieved by undertaking a systematic approach to the exploration of a critical friendship between two academic support staff members alongside reflections from a recorded, focus group interview with nine STEM teachers. Four self-awareness data generated processes were used: (1) self-reflections; (2) collaborative reflections; (3) reflections on pertinent literature findings and (4) reflections from nine STEM teachers. A thematic analysis of the data was undertaken, which resulted in the discovery of three turning points such as moments of understandings that challenge assumptions and/or lead to new insights. The findings indicated that a STEM-centric, scaffolded approach that utilised the scientific method for reflective practice enabled the development of a shared understanding around teaching and assessing reflective practice for STEM teachers. First, because it boosted self-confidence and second, because it reduced scepticism around reflective practice as a non-scientific form of learning.

Establishing school university partnerships to teach science – Does what worked for us work for you?

Concerns over the quality and amount of science teaching in Australian primary schools has led to a concentration of research on the methods of delivery of science education. There is a growing interest in both Australian and International contexts on building teacher knowledge and confidence to teach science, how science is taught at the primary school level and also how pre-service teachers are prepared to teach science. The Science Teacher Education Partnerships with Schools (STEPS) project is one response to these concerns. The STEPS project is a collaboration of five Australian universities that each independently set-up their own school-based partnership approaches with schools to deliver their science education programs. Each university aimed to provide pre-service teachers with the genuine experience of teaching science while being supported by university teaching staff. The project has drawn on feedback from pre-service teachers, teachers, principals and teacher educators involved at the five universities to examine the prevailing practices and led to the development of a set of tools and process, referred to as the Interpretive Framework (IF)(Hobbs et al. 2015). The IF describes how to create and maintain effective partnerships with schools, based on this research. This current paper reports on a survey conducted in 2014 which aimed to feedback from teacher educators across Australia to explore the extent to which school-based teaching opportunities in science for PSTs were in use across the country and to identify the range of approaches and theories driving their practices. Some respondents were followed up for interview and key factors were analysed and reported here. These data will be used to further refine the IF.
