Leading professional learning in an Australian secondary school through school-university partnerships

As the limitations of one‐off and disconnected professional learning programs for teachers are recognised, there is widespread interest in building learning communities and professional learning teams within schools. When considering how to build local learning communities, school and university partnerships are seen as offering rich possibilities for transformative professional action. Set in the context of the international agenda of “Education For All” (UNESCO, 2005) a model of sustained on‐going professional learning, developed in one large secondary school in Australia, is analysed. The social practices that generate action and participation for partnership members are then scrutinised for the legitimacy of school‐university partnerships and the contribution to enhancing teacher learning.

Mining characteristic relations bind to RNA secondary structures

The identification of RNA secondary structures has been among the most exciting recent developments in biology and medical science. It has been recognized that there is an abundance of functional structures with frameshifting, regulation of translation, and splicing functions. However, the inherent signal for secondary structures is weak and generally not straightforward due to complex interleaving substrings. This makes it difficult to explore their potential functions from various structure data. Our approach, based on a collection of predicted RNA secondary structures, allows us to efficiently capture interesting characteristic relations in RNA and bring out the top-ranked rules for specified association groups. Our results not only point to a number of interesting associations and include a brief biological interpretation to them. It assists biologists in sorting out the most significant characteristic structure patterns and predicting structurefunction relationships in RNA.

Popular culture : a resource for writing in secondary English classrooms

This chapter explores how a secondary English teacher working with students aged 14-15 enabled them to use their popular culture practices as a resource for writing. The chapter provides examples of conventional classroom situations in which this teacher created a space for students to bring their own semiotic resources to bear on the curriculum. It argues the need for English teachers to become sensitized to the complex literacy practices in which their students engage outside school and to the ways these practices are bound up with their social relationships and sense of identity. The discussion challenges conventional understandings of ‘reading’, ‘writing’, ‘speaking’, and ‘listening’ as components of the English curriculum, arguing that a more contemporary understanding of literacy must take into account the multi-modal practices in which students engage in beyond school.

Performance evaluation of different ultrafiltration membranes for the reclamation and reuse of secondary effluent

This study investigates and compares the performance of two different types of ultrafiltration (UF) membranes in the recovery of water from secondary treated wastewater. Filtration experiments were carried out on a pilot scale cross-flow unit using synthetic wastewater similar to the quality of secondary treated wastewater by varying the operating parameters such as transmembrane pressure (TMP), feed composition and membrane configuration. The filtration experiments demonstrated that the flux recovery through spiral polymeric UF membrane was more sensitive to the variation in TMP compared to the tubular ceramic UF membrane over the range of TMP studied. The resistance in series model was used for the evaluation of the resistance to the permeate flux. The fouling resistance, particularly irreversible resistance compared to reversible resistance plays a major role in the total resistance for the tubular ceramic membrane. In contrast clean membrane resistance is the major contributor for the total resistance of the spiral polymeric membrane. Finally, the effectiveness of the filtration treatment was determined by evaluating the rejection coefficients for various pollution indices of the wastewater. Significant differences in the performance of the membrane types were observed which are likely to impact on the selection, operation and maintenance of the membrane system.

An investigation of middle secondary students' mathematical conceptions of rate

This study identified four educationally critical aspects of ‘rate’ through analysis of phenomenographic, video-recorded interviews with Year 10 students. Further analysis indicated understandings in one representation or context were not necessarily transferable.

Homophobic bullying in secondary schools : a prejudice worth fighting about

This thesis reports on the outcomes of the first mixed-methods controlled trial of a manualised anti-homophobia program with 72 year nine students.  The program tended to produce small improvements although most of the changes occured in the control group which experienced an overall worsening of homophobia.  Qualitative data suggests that the program has led to an increase in awareness of homophobia and highlights the need for specialised teacher training.

Computers are taking mathematics into the next century : gender differences in attitudes of secondary mathematics students to the use of computers

Secondary students who participated in a computer enhanced mathematics program expressed positive attitudes about the use of computers. They viewed computers as a source of pleasure, success, relevance and/or power in mathematics. Girls were more likely than boys to qualify their support for the use of computers and more likely to view computers as a source of success in mathematics. Boys were more likely to claim that computers brought pleasure or relevance to mathematics learning.
